[OHPV-list] Crank Arm length

[Jim Pedersen]

Crank-arm length is certainly one of those subjects that can almost start a 
riot.  Like others have said, it's important to enter the discussion with 
some clear intent of what you wish to get from any change to the setup of 
your bike.  In designing my last two frames, I found it necessary to really 
scrutinize how I intended to ride before choosing components.  Here's a 
couple of interesting references I have used in the past:

(I can hear someone out there saying it now .... "D@&% engineers!".)
