Dow Road Night Ride
(updated: Dec 29, 2006)
Some photos from yesterday's night ride at Dow. I managed to get a photo of each rider. Man did I have a mechanical - my crank arm came off. And later, I flatted. And there were light problems, too. What is it with me and singlespeeds? Maybe it was all that stuff I said about singlespeeds earlier coming back to bite me. "Oh, it's the chain's fault, well here's a loose crank arm for ya too, buddy."

Erol, if that bike has sliding dropouts, your crank arm fell off because your chain was too tight. This is especially common with external bearing bottom brackets, but I have seen it on isis and squares too. You have to check chain tension with the arm at several different positions, because no chainring is perfectly round. We rode UNCW last night, and I had an ipod mechanical if that makes you feel better. Lets ride this weekend, I might let you try my RacerX29, because I really want to ride the single.

Didn't seem that tight, and I haven't adjusted it or anything since I got it. But I may not have tightened the two bolts on the non-drive crankarm enough because I've never had this happen on the Kona. But then the chain always fell off on that bike. I guess I can't win - too loose and the chain falls off; too tight and the crankarm works its way off.

Yeah you adjusted it, you put a 2 piece XT on there. Too much chain tension will cause the pinch bolt to loosen and pull the arm off. Who installed your cranks? If you want, I will set it up for you.
