Can anyone tell me what the axle width is for the Dura Ace 7402 cranks? I dont have the original bottom bracket, and want to use something generic and practical, like the sealed Token bottom brackets.
Thanks in advance!
7400 pre-dates the internet, so there are no Shimano docs online.
Do you have any BB that will mount the crankset? If so than you can measure the resulting chainline and calculate the needed axle length.
Information is here: http://www.sheldonbrown.com/bbsize.html
Bottom bracket axle length is 112 mm unless Italian, then 113 mm.
Good one! Sometimes even such as I forget to check with Sheldon first. :p
