I recently purchased a second hand 2010 felt tk3 and looking at upgrading my chain set from stock standard 3/32 to 1/8. I have been looking at different brands like Miche and Sram but not really confident with ehat will suite my current bb. From what I can find it's a 68mm fsa square shaft. Will I need to replace the bb to fit new chain set?
Your assistance would be appreciated.
Thanks
