Serfas CK-1 Combo Kit 1 (Product Review and Giveaway)

01 Jul

Even if you don’t have a clue about how to repair a flat tire or make minor adjustments to your bike, you really need to carry a tire repair kit, tire pump and mini-tool with you on every ride. You might not know what to do with the tools, but usually someone with offer to help you—but without the right tools you might have a long walk home. The folks at Serfas recently sent me one of their basic repair kits, the Serfas CK-1 Combo Kit 1, to review. This kit includes the items needed to repair about 90% of the problems you are likely to have on a normal bike ride. If you would like a chance to win this kit just keep reading!

The tire pump in this kit is the Serfas BS-1D Big Stick Pump and it normally retails for $18. This pump is 11″ long (17″ with the handle extended) and works with both Presta and Schrader valves. The pump should be able to inflate your tires up to 110 psi, but, like most air pumps, anything over 100 psi requires a bit of work. This pump weights just a little over 7 ounces (205 grams) and will easily attach to your seat tube with the included mounting bracket. The handle on this pump folds out and makes it very easy to grip.

This kit includes a small mini-tool that includes seven Allen keys (2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm), a Phillips screwdriver and a Torx wrench (mainly used for disc brakes). If you are in need of mini-tool with a with a wider selection of tools I would strongly suggest the Serfas ST-17i CO² Inflator / Mini-tool (the best all-round mini-tool I’ve ever seen).

Bicycle Mini-Tool

The tire repair kit is rather generic—a lot of companies sell nearly identical kits. This one includes two tire levers, four patches and a small tube of patch glue. There is also a small piece of sandpaper that is used to scruff up the area around the puncture before you apply the glue. The only thing missing here is a small piece of chalk (I don’t know of company that includes it with their tire repair kits, but they should). When you are trying to find the puncture in a deflated tire you first need to partially inflate the tube and then feel your way around the tube until you find the leak—and once you find it a piece of chalk makes it real easy to mark the location (if you don’t mark it well when the tube is inflated it will be very difficult to find once you let the air out).

Also included in this kit is a medium-sized saddle bag (6″ long x 4″ wide x 4.5″ tall). This bag is also expandable—just unzip the bottom zipper and the bag becomes a whopping 6″ tall! Even with the expandable bottom closed there is enough room for the tire repair kit, mini-tool, one MTB tire (or two road tires), your ID and a bit of cash with room to spare. This bag also has a key ring holder inside so won’t risk loosing your car keys every time you open the bag. The bag attaches to your bike with two Velcro straps—one strap goes around the seat post and the other around the rails of your saddle. One more thing: there is a piece of 3M Scotchbrite Reflective Trim all the way around the saddle (something I wish all saddles had).

Serfas CK-1 Combo Kit 1 retails for $40 and is available from the Serfas website or from an authorized Serfas retailer (most bike shops and REI stores).

    When I switch bikes, I sometimes also have to switch tools, and occasionally find, when it’s too late, that I haven’t brought the right kit for the bike I’m on. Looks like Serfas is doing a good job putting together a universal kit. If I still worked at the bike shop, I’d enjoy selling this instead of all the separate items. The customer leaves with what she needs, and she’s had to consider fewer individual purchases. Easy for her; easy for me. Win-win.

      I agree, Sam. As a female and very new to cycling, I remember having to purchase all this for my bike, individually. I would have loved to have purchased the whole kit instead of all the parts.

    I need it because I am a beginner rider(Just bought a bike a month ago) and your blog has given me some insight and I am eager to learn more on my own and through your blog!

    I’ve been following your blog for quite some time now. This is yet another very helpful product review. Here’s my reasoning for wanting to be considered:

    I’m getting back into cycling after walking away from it in my mid-20’s. (I didn’t intentionally walk away, life just got busy.) I just purchased my first road bike in March, since then I’ve put 800 miles on it. At the same time I purchased my bike, I purchased a bike for my son so he could ride with me. I have a kit for bike repairs on my bike, which is fine when we ride together, but more and more recently he is riding on his own. I’d love to win this kit for him to have on his bike. As a single mom, trying to get “geared up” in the cycling world, can tax the budget. (I don’t operate on credit.) This would be a windfall for me, and my son would be absolutely ecstatic over it. Plus, his birthday is coming up on September 1st. 😀 Thanks for considering us.

    Reblogged this on My Life In Gear and commented:
    I absolutely LOVE All Seasons Cyclist. He reviews so many cycling essentials in a clear, non-technical manner. This is yet another example of one of his great reviews. Plus, I entered to win the kit for my son’s bike. Shhhhh! Don’t say anything. His birthday is coming up soon. Anyway, read and enjoy one of my favorite cycling go-to resources. He’s like having the bike ship at your fingertips!

    This is great. I just purchased some of these essentials. A great review, and very helpful since I had no idea about the chalk. I don’t have patches, but I do have a spare tube in the kit i just put together. Thanks for sharing! 🙂

    • All Seasons Cyclist

      July 6, 2013 at 9:08 PM

      You only need the chalk if you plan on patching the tire. I always carry a spare tube, but on a few occasions I’ve had two flats on the same ride and had to patch up a tube by the side of the road just to get home!

    I could have used this 2 nights ago. Although I have all the stated gear I was on my mountain bike when I asked a couple of cyclists if they needed help as I passed and they needed a pump. I stopped and went to get the pump off my rear bag and realized it was on my road bike. Luckily another cyclist came by shortly after and had a pump. That’s why I could use this so it stays on one bike all the time.

    I just started following this blog and thank you for it as I have already loaned out “Cycling Home from Siberia” from the library for some lazy after cycling reading.

    Coincidentally I was thinking about your blog a few hours ago.

    On vacation here in the Finger Lakes and it’s been raining all day. We said screw it a went for a hike anyway and found ourselves cold, soaked, and still many miles from the car and still determined to get more miles in.

    Much to our surprise (we didn’t expect hikers, runners, cyclist, or anyone to be out) a group of intrepid cyclists bundled up in rain gear began to pass us with smiles and weather jokes and hellos and a quick question as to how far it was to Watkins Glen.

    I immediately thought about your blog and the cold, wet, muddy, windy condition they were in and how likely you might ride in the same conditions but likely with even more preparedness than even these guys.

    And I also thought how much I love biking and some of the inclement conditions that I have ridden in or I have found myself in. Yet I was thinking that you would not catch me riding on a day like this.

    Except I was hiking in it instead.

    So I guess it’s half a dozen of one and six of the other, as they say.

    As I now sit/recline/lay uncomfortably on an air mattress in a small tent (covered in a huge, ugly but very dry tarp) with my wife and two large dogs as the rain pours down outside, I find great enjoyment in reading your current blog entry as well as some previous ones that I had skimmed before.

      July 1, 2013 at 9:58 PM

      Marc, since it doesn’t appear as though you entered the contest I will go ahead and respond to your comment. First, those guys sound like they were having a great time! Second, if you could go hiking in that weather then certainly you could have gone cycling — you are going to get wet either way, but I’d rather ride than walk ANY day. As I always tell people about cycling in below zero weather — the hardest part is the first 500 yards after you leave your house. Ride safely!

    I just came across your blog and could really use this kit. I’ve been cycling fairly seriously for about a year and a half. I’m slowly building my arsenal of bike tools and accessories. This is something I don’t have yet. Building a collection of tools and accessories is not easy when on a budget!

    I am currently waiting with impatience for the arrival of my Tern D7i via FedEx. I just bought it this past week in Decatur, GA at Houndstooth Road bicycle shop while at a Suzuki violin Institute in Roswell, GA. Honestly, if you are going to Atlanta for any reason, check out the shop. is the website where you can get hours and location information for the boutique. They are within a block of the Decatur train station. (My train adventures I’d tell you if you ask.) As of July 1st my picture is still on the front page of the website with my Tern bike that is currently in transit to central NY state. Jae, the owner, was beyond fantastic. His shop (links on his wesite) has amazing European bikes and accessories. These aren’t the racing type spandex accessories, but the let’s-bike-to-the-store or bike-to-work in real clothes kind of accessories. Colorful fair trade bike baskets, waxed canvas bag sand saddles by Brooks, neat reflective capes from, chic rain gear by, yakkay, nutcase, and helmets and more. There is so much cool stuff there, it’s hard to leave not wanting to spend thousands of dollars. The bikes he carries are Pashley, Bobbin, Pilen, Bella Ciao, Xtracycle, Tern, and many other European bikes that include civilized items like chain guards, fenders, and rear racks as standard equipment. My intention was not to buy a folding bike, but to ride and try out the Dutch and English bikes while in town for my conference. Jae convinced me I needed to test drive the Tern. Wow, it ended up just what I was looking for, and I didn’t even know before I arrived! With no Tern dealers within hundreds of miles of my home, I decided to buy and ship it home.

    Since I was going on a plane I decided to pass on buying the Tern multi tool figuring TSA at the airport would confiscate it if I brought it on board. So if I don’t win this, I know I will need to go and get something like the kit you reviewed. I’m hoping with my Tern’s Kevlar coated citizen tires, the patch kit won’t be necessary. Wishful thinking? I’m looking forward to my new riding adventures, better health, less pollution, and hopefully training my golden retriever that he does indeed like bikes, and that he even wants to be pulled behind one in a cart to the park in the mornings instead of in the car! Wish me luck!

    Another fantastic article about a necessary item! Why do I need it? Because I’ve just started commuting to work 2-3 times a week and switching my gear bag from the road bike to the mountain bike is a huge pain in the… Posterior! I purchased most of these items for the road bike. Received the CO2 multi-tool as a gift (awesome!). To have the whole kit specifically for bike #2 would be all aces!

    One question, does the bag have a loop for a tail light? That would be good to know.

    Thanks again for an awesome post!

    • All Seasons Cyclist

      July 6, 2013 at 9:10 PM

      There is a loop for a taillight on the back of the bag — I should have mentioned that in the review!

      • Adam C. Henderson

        July 6, 2013 at 9:20 PM

        I see the straps holding the bag to the seat are velcro, how do you feel about velcro? I’ve seen it wear out (lose its grip) when exposed to weather and grime. What are you thoughts on this? My road bike bag has the plastic pinch connectors and is wearing famously.

        • All Seasons Cyclist

          July 6, 2013 at 9:40 PM

          I’ve had saddlebags that connect with both methods. While the Velrco and attract grime, the bag itself will probably wear out before the Velcro. There are several great saddlebags that have a “Quick Release” clamp and they are VERY easy to use.

    Good review and great contest. I admit to needing it (wanting it) because I am just getting in to riding and one of my greatest fears is being left out there stranded. Well greatest fear other than being run over by a car or falling in a pothole and winding up in Storybrook, Maine. I have even checked out the “Bicycling for Dummies” book from the library! That got some strange looks – “what does a middle aged guy need with a bicycling for dummies book? Just get on it and ride.” Did I tell you I am insure about this?

    Anyway, thanks for the site, the content and the chance to enter the contest.

      I’ve never seen “Bicycling for Dummies” at the bookstores, but it sounds like a great addition to the series (I own a lot of the other “Dummies” books).

    I just got a friend of mine into bicycling. His name is Dante and he works in my building and never would consider biking until his 11-year Hyundai broke down. He lives about 12 miles from his work and on hills, so biking is the last thing he thought about. He’s also overweight at 200 lbs. for his 5’5″ stature. I told him about how bicycling could be his primary mode of transportation and could possibly change his life. One day he bought a department store bike without asking my advice. He rode for a month on it and it broke down, however he enjoyed so much. I told him about mini velo and he fell in love with it because he can also takes it on the trains. On his ride home from work, his rear tire popped within the first week he got it. He didn’t know how to repair a flat and instead, he spent a lot of money to replace the tires. Also, where he lives it doesn’t even have one local bike shop. He has to come into San Francisco for repairs. So I would like to win this kit for him so he can become more mechanically skilled and never have to be afraid of a flat again. Now he rides his bike more than I do on my bikes. He’s obsessed, thanks to bicycles! Oh and after 7 weeks of biking, he has lost 27 lbs! Yeah, that’s how much he rides…

      Sorry you didn’t win, but a friend of mine called me and was impressed with your entry on behalf of Dante and he told me I ought to something for him — I mean, anyone driving an 11-year old Hyundai needs some help!

      While I don’t have a new kit to send him, I was able to go through the Man Cave (my garage) and round up a fairly decent amount of gear — a medium sized saddle bag, tire levers, compact tire pump, riding glasses, two taillights, a wired bike computer, and a multitool. If Dante would be able to use this stuff I would be more than happy to mail it to you. All of this stuff is used, but it still works.

      If you would like me to send this box of goodies just send me a mailing address and I’ll drop it in the mail next week (use the “Contact” form at the top of this page).

        Thank you. Greatly appreciated! Your site is awesome! I’m gonna follow it.

        Being the engine, cycling has made me conscious about my physical health—I hope to remain physically fit so that I can keep up with those steep hills. And I am also finding peace during the act of cycling in the open air—moving, improvising, and being aware of the very moment you are in.

        Thanks again for the useful items. I am definitely gonna need ’em 🙂

          July 17, 2013 at 3:28 PM

        I went cycling for a 50 mile round trip last Monday from Daly City to the Golden Gate Bridge and back. But I got a flat on the way back and the cycling kit you’ve generously provided saved my day. Since I always brought spare tire tubes with me, I was able to replace the flat tire in 15 minutes using the air pump from your kit (I always thought that pump would take forever, but actually not at all).Then my hands got dirty from the chain oil but your cycling kit also contained cycling hand wipes–lucky me! And I was able to know how fast I was going and that the round trip ride is 50 miles–thanks to the cycling meter you’ve also provided. I feel like a pro with those kits and people walking by were looking at me and looked like they were impressed at how prepared I was. Thanks again David. Now I know how important those cycling kits are, thank to your help.

          Dante, I am really glad you were able to use the kit I sent! Some of that stuff was just sitting in my garage and I didn’t need it anymore — i was just waiting to find someone who could use it. Ride safely!

    As I already have all those items I will not be entering this particular give away. (Actually, I have either not entered any…or cheered for someone else to win it lol.)

    Nevertheless, the all-in-one kit is a GREAT thing to get.

    Now only if they could stuff one of their women’s cycling jerseys in there…omg they have such cool jerseys! lol

    • All Seasons Cyclist

    I was forced to “retire” early from 12 hour night shifts where my weight and constant hustle was “tearing up my knees and ankles” according to the specialist. It was my choice. The other “choice” was a “new” knee, at the very least, thousands and thousands of dollars I didnt have, months laid up, all without promise of it feeling better and with arthritis in my back enough to deal with regularly, I didnt want knee problems to increase and totally incapacitate me. Too many years yet I hope! At age 60 and 250lbs I had enough background from my younger years to know there was yet another, harder earned yet longer lasting” option. Exercise (carefully) and lose weight………a LOT of it. Running was out, walking proved to be a bit much pain wise so….cycling (sensable) hit my attention list and off I went researching effects of proper cycling on one’s joints….and also found the many added benefits listed that I was aware of mostly, to staying in shape (other than ROUND, LOL). On the 4th, I was “only” on my third week of cycling after spending money I didnt have to spare on a hybrid/comfort bike weighing 40 lbs. At first, I didnt think I could do it but being bull headed does have some advantages. Starting out, 2nd gear on the Nexus 8 was ENOUGH for a mile. Yesterday, July 4, 2013 I hit my personal “best” (dont laugh, lol) of 34 miles in two rides, 10 mile pace of 58 minutes plus. The afternoon ride took me to hills I had “forgotten” about yet I made it but while riding I gave thought to my sons, both busy, both miles away with family. What was I going to do if I had a flat?…..or chain came off, or worse? I had no tools with me and was 10 miles from home on a holiday where even my few friends would be REALLY put out helping me, if needed. I actually found this link and site looking at tool kits I could carry handily on the bike for when funds allow again. Is it working? Yep! 3 weeks in the saddle, working up as I can and weather permits, I’m down two full sizes in jeans. No scales so no clue on lbs but inches mean more to me than lbs.A long, long way to go! Am I SORE……..oh yes! but………keeping track on my cycling on Endomondo has been fun, encouraging and informative…..AS LONG AS I DONT LOOK AT WHAT OTHERS RIDE DAILY, LOL! If you dont find a young person starting out for this kit, to encourage them to STAY AT IT rather than wait like I did, I would greatly appreciate it’s addition to my new found life in the saddle. Failing that I could sure use a LIGHTER BIKE! ROFL. Motoring a total package of 275lbs or so on a hill REALLY wants you want to LOSE WEIGHT! 🙂 If riding now….STAY AT IT! A 45 year “break” is a tough row to hoe! God Bless!

    • Steve

      July 5, 2013 at 10:12 AM

      MAKES you want to LOSE WEIGHT…I mean. Duh. God Bless!

      July 5, 2013 at 12:48 PM

      I’m also getting back on the bike after a LONG break. Not, 45 years, but almost. I started out with a hybrid and three years later upgraded to a road bike. Three years ago, it nearly killed me to ride 7 miles at about 7 mph. Now, my longest ride to date is 62 miles averaging 13.5 mph. It’s not racing speed, but I’m not poking around either. Hills still kill me. I need to lose about 40 pounds and then, maybe, just maybe I’ll be able to fly up the hills like the fast guys who are 15-20 years OLDER than me (I’m 51). I just wanted to say you are not alone in your journey, and you can do it!
      As my son is fond of saying when we ride up hills together, “C’mon, Mom. You got this!”
