Bb86 question

bukowski102

have a giant tcx slr1 with bb86 fsa cranks
Need a new bb and My question is will a sram bb86 bottom bracket be compatible with this chain set
I'm thinking its a pressfit?
Many many thanks

This chart suggests that your crankset uses a 30mm dia. axle, so as long as the SRAM pressfit BB you want to use has a 46mm O.D. and 30mm I.D. and is designed for a 86.5 wide BB shell it should fit, but I would double check with the supplier first. I would also double check the I.D. of the BB shell, as I thought the I.D. of the BB shell on Giant's pressfit frame was 41mm not 46mm.

So thankful for your info, yes it is that exact bike, I've ordered the sram bb86 after being told by giant hope it will work!!
Thanks again
