What bottom bracket size /model do I need?
Hello people, so I'm working on a bike build and got a frame recently second hand but when I measure in the inside tube, it doesn't add up, so bit confused.
Frame is Giant defy advanced 1(2014) Medium. From online specs it says Shimano press fit, but no sizing. I'm also using Shimano 105 cranks, if that helps.
Appreciate the help!
