GXP to Hollowtech II
My winter bike has a SRAM/Truativ crank and chain set. The rings are fairly worn and need replacing. The rest of the groupset is Tiagra 4600 and I was going to change the crank and chainset to a Tiagra 4700 setup. I have googled and searched endless threads and think Ive found the answer but then read another thread and find a contradictory answer to the previous one. So can anyone definitively tell me can I simply remove the crank/chainset and GXP cups and fit a Hollowtech II BB and tiagra chainset? The bike (Ridley Compact) has an English thread BB.
