I'm building up a bike for someone who impressively split his rear dropout on a steel LandShark
frame. He has decided to retire the Shark and has thus purchased a nice titanium frame.
I'm moving the 9 speed Dura Ace group over to the new bike. This is my first encounter with
splined cranks.
The question: how much force do I put on the self-extracting Allen bolts? I know that with
traditional tapered cranks, the answer (in the absence of a torque wrench) is "pretty damn hard"
with an eight-inch Crescent wrench on the standard extraction tool, or "until the edge starts
painfully cutting into your hand" with one of those 14/15/16 combo guys that I think are termed
"peanut butter" wrenches.
Is "pretty damn hard" appropriate for the Dura Ace? I'm using an eight-inch ratchet with the 7 (?)
mm. Allen fitting, simply because I don't seem to have a traditional Allen wrench of that size.
