Hard luck for sure on your brevet. So oddly enough I had a lose non-drive side crank arm this week commuting as well. I was really pushing hard on my single speed XO-3 and noticed a huge oscillation in my left foot. I limped the final 3 miles hand tightening the hex bolt headed crank bolt (no easy hex wrench socket) and stopped at my LBS before my return commute.
The mechanic grudgingly gave me a socket wrench to tighten the bolt myself but told me that a crank bolt is a'compression fitting', and that once it shows signs of loosening it will never stay tight and is fixed only with replacement of the crank arm... I said thanks and was on my way. It's staid tight fit me the remainder of the week but I'm now curious about this 'compression fitting' tightness issue and it seems in line with this thread... Can anyone confirm? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
