Square taper BB to Hollow... Help

leolun · 10-07-2016 12:53PM #1

Hello, I have a 68 mm square taper. I can't find a replacement for a broken crank so I need a full set and there are very little options. So I want to change to hollow BB so I have more options.
Do you know any website that will help me choose the right hollow size to replace my BB?

This bottom bracket and crankset should suit you. The bottom bracket is on special on ChainReaction, its the same price as a Tiagra BB.

Before you got down the route of replacing your bb, are you sure you need to?

What crankset would you like? Is it not available in some kind of format for square taper?

You're opening up a world of pain by messing with a functioning bb.

If you want to get a crankset to suit your current bottom bracket, this one should suit:

May be available cheaper elsewhere.

My crankset is broken, needs replacing. And since my BB is squaking might aswell get something new. It's a track bike, so there's very little options on BB square tapers, found a lot more for Octa.
