I want to get a Isis bottom bracket for a Inbred 29er Swap-Out Frame. It to be run as a single speed. I see from their website it has a 68mm Bottom Bracket shell. My question is what width of BB do I need?
Advice much appreciated.
Scandal 29er is 73mm if that is any help
Hi I take it thats the shell width not the axle length?
Axle length depends on chainset and if you're trying to do anything special with the chainline. Shell size doesn't affect what axle length you need. If you're using spacers on a cassette hub, you can.play around with the sprocket position to.sort chainline, so you can be quite flexible on axle length. Best just go with whatever is recommended for your cranks.
Ah I see, thanks. The cranks are Bontrager, taken from a SS Trek 69er so I have no tech info to go on.
