Title: 756 bottom bracket
Post by: Nightowl on May 04, 2006, 11:47:30 pm
Hi all quick question, when shopping for a BB should i stick to the 110mm spindle or use what ever the crank manufacturer recomends ??? ???

         Good day all--Matt

You should use what the manufacturer recomends. You could try what you have but there may be clearance problems with the shifter or crank hitting the swingarm.

I would take the gamble and use your 110 BB. If the shifting works, you could shave your cranks for more clearance and increase your Q factor with shims on the pedals. Does it work well now?

Now class, what did I just say? (Did I do good Simon?)

As Terry origionally stated go with what the manufacturer recommends,
so 113mm should be fine.
Anyway your only 3mm longer than standard and I'm
sure everything will be fine.
