Hello, I intend to replace the bottom bracket on my long suffering training bike soon. I use a Dura Ace 7402 Crankset. My understanding from Sheldon's site is that this would normally require a DA 7402 BB which is 68-112mm (8-speed 1990-95, Right end of spindle 3 mm longer 112 for 68 mm bb).
Could I use a Shimano XT UN73 Sqr Taper 68-110mm OR 68-113mm with this crankset ?

FWIW, I've successfully used a 107mm Shimano UN-7X with a FC-7402. It was a little narrow, though my bike allowed it. I think the 110 might be a better fit though.

The 7402 crank used a 113mm JIS tapered BB, 115mm for Italian threads. Use a UN-72/3 of 113/5mm length.
