Title: Bottom Bracket for Thorn cranset?
Post by: CPeachey on October 24, 2009, 12:39:22 PM

I have a new Thorn 155mm crankset which is bottoming out when fitted to a Stronglight or Shimano JIS bottom Bracket.
Can anyone tell me what BB I need please?

Sounds like you just need a BB with a longer axle - how long depends on the application of the crankset and what chainline you're after.

If using as a triple 113, if only using as a single speed crank as on our Raven bikes 110mm
