Apparently, shifting times differences measured with new and worn "10 speed" chains are marginally low to allow for any statistically significant conclusions. So I guess the message is don't fret unnecessarily over your chain length.
Links to the two studies courtesy of Wipperman are : Test on new chains, Test on worn chains.
Two plots from upshifting and downshifting tests are shown below.

Speaking of chain wear, Wipperman's most conclusive test results on chain wear ranks themselves as number 1 in the list of 10 speed chains, which they attribute to their solid, no frills side plate and solid pins. Link.

Truly needed is an explanation of why belt drives are not par for the course in wet climates. I don't own a belt but have a natural antipathy for rain and the resultant mess in my links. I still ride however (79 inches in Palm Beaches last year and at least 76 are in my shoes!)
ReplyDeleteI think due to the closed design of the belt, some challenges arise in dirt being lodging in the belt. Why else has motorcross bikes not switched to belts yet? Any other views?
ReplyDeleteOne answer is that rain is HUGELY less of a problem so long as you have good fenders to keep the road muck off of your drivetrain. The fenders also keep the road muck off of the rider. Win-win.
