Giant TCR3 2012 Bottom Bracket
I'm looking to replace my bottom bracket on my TCR3 2012 and am a bit confused! The current BB fitted has 'BB AL86 19' etched into it. I've been on Wiggle and it suggests that 'FSA BB86 Bearing Kit' is the one for the job. Having read their reviews, they say that it is compatible, but another post states it is a 24mm diameter instead of the 19mm one I need. Advice very welcome, please!
