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.

    Yes, you can do that. As you say, simply remove SRAM chainset and BB. Replace with Hollowtech II BB and Tiagra chainset.
