Mrs S is looking to increase her gear ratio on her time trial bike. She currently has a 53t big ring on an Ultegra chainset, and is claiming that she is running out of gears while racing 10's and 25's (her maximum power output comes at a cadence of 65-70).
Do I need a new chainset (I notice that FSA do a 56t tt ring), or is there something that I can do with what she has? Also, if we do increase to 56, will I need to increase the inner ring from 39 to 42 or so?
Wouldnt really matter that much except she is showing some aptitude....
