    Homebrewed chainring and Specialized cranks

    I love my new crank setup. Homebrewed spiderless Ti chainring, Specialized 180mm cranks and Zipp Vumaquad bearings. This is on my 2011 Stumpjumper SS.

    Is it the camera angle or how close is the ring to the chainstay?

    The pic is deceiving. There is plenty of room between the ring and the chainstay.

    Those cranks are cool and even more cool is the little pedal strike caps at the end of the arms. I would caution you to put some threadlock on the bolt that joins the cranks together and tighten that thing way above the spec's. I had these on my stumpjumper and they came loose in the middle of a race. Not cool, and while I managed to scavenge an allen wrench that was long enough to tighten them from a passing racer, I couldn't put enough torque on them to stay together. You need a socket and ratchet to tighten them to or beyond spec. It also happened to one of my teammates on his stumpy.

    They're nice, light, and stiff but if they ever come loose on you you'll hate them for life. I have a pair of Lightnings (the non s-works branded predecessor of these) that I gave a teammate because I just couldn't put any trust in them anymore and didn't want to put them on any of my bikes. I actually broke one of the arms (Lighting replaced it under warranty) on that set and then after the s-works came loose on my 2x10 bike I completely gave up on that design. With that said, there's a lot of people riding them and a lot of people who swear by them. Unfortunately my experience with them was jinxed.

    I've been keeping on eye on the bolt over the past 2 months. So far, so good. The crank protectors I re-used from my RaceFace crankset that I took off.

    Wow! Didn't realize that it was the only one you've made for the S-Works cranks. Very cool!
