I'll be honest, I've never felt that uncomfortable on my bike. I've had issues with feeling cramped. I've had issues with hand numbness. But I've never been so completely flummoxed by bike fit that I couldn't sort it out on my own.

I know fittings are popular and "fit" is a valuable sales item when buying a new bike. But not for me.

The different frame angles make subtle difference to ride comfort and handling. (I must be missing something important.) If you're shopping outside your usual style of bike, I can understand the concerns. I wouldn't know where to begin with mountain bike fit. But road bikes are fairly straightforward.
