Reading the thread on loaning a bike many forum members mentioned loaning of their bikes but not allowing the person to make any adjustments. Aren't all our bikes "custom" fit to ourselves?
When do you consider getting your bike refitted or are you married to the fit you have now? I know now with the weight I've lost I should be my bike refitted. I don't have the "gut" I once did and I can bend forward more easily which changes my riding position.
