Hi Robin I know you posted this a while ago. But I'm experiencing the same problem. I got the bike the Saturday before 94.7 (I know I know)...but the thing completely destroyed me. Before this one I had a Giant OCR 1 with triple rings. And leaving to the race I was training on an MTB. I was lucky I finished within time. That was my first 94.7. So I just wanted to know how you resolved the issue, did the training eventually help? I'm a very heavy novice if I may add. Thanks in advance. Regards Max
