SRAM S100 Courier Crankset

I bought this crankset for a budget single speed commuter build. This is the first and last isis drive system I will ever buy.I don't have quadzilla leg strength, but when I sprint, this crank sounds like it's going to fall apart. I've rode for <100 miles so we'll see how much longer the isis bb will last. IMO, spend a little more and get the s300 with the gxp bb drive system.

Great crank! BUT!! IT IS DEFINITELY NOT THE ONE PICTURED....That being said.. What did arrive looks awesome, performs well and feels quite stiff when compared to the stock crank that came on my SS. Would definitely have to think this is one of the better crank options out there, dollar for dollar, if you're looking to upgrade your SS. Added some pics to hopefully give any future shoppers an idea of what will actually arrive when you order. (Personally, I think what I got it better looking that what is pictured, but that's just my opinion.)

Well, I wish it was 175cm. I can definitely feel a difference of the shorter cranks. However, this is a decent low-cost​ single speed crankset.

I bought this crankset for a fixie I was putting together and it has exceeded my expectations. It does what it is designed to do and has been a great success in terms of durability and power. The power spline system itself is also high functioning. If you plan on using this on a fixie, I would highly recommend it but might consider a shorter arm length than the 170mm that I chose.

I like this crankset, I don't feel like I am going to break it. If weight is not your primary concern, this is the best deal you are going to find. Plus it looks sexy. I actually had sex with it before I put it on my bike, and then again the next morning when we woke up.#bianchi#superpista

Either SRAM used a gallon of locktite or the wrong size of of bolts. To change the 48T chainring I had to drill out two of the bolts, and yes I have the special tool but all that did was strip out the back end of the nuts, The bolts appeared as if they were forced into the wrong size. SRAM could have just left it apart. Haven't tried installing them on the bike yet.

Broke too soon

I am on my second S100 crankset in less than two weeks because of the hard to remove chainring bolts. I stripped the chainring bolts on the original unit, even though I was using a chainring nut wrench to prevent them from spinning. The bolts themselves seem really cheap, and they are really loud and creaky as you try to remove them. Overall, poorly thought out.

For the price, you can't beat the quality. It's not the lightest crank out there, but it's strong and looks quite good. It does use a power spline BB which is slightly annoying, but other than that, can't complain.

Stiff af, but heavy gear so tough on climbs.

Would be 5 stars if I didn't have to drill out the chainring bolts to change the ring, otherwise very solid crank i went for the 109mm spindle bb and chainline is perfect, my bike is silent.
