I really dont like it when doctors do that ... esp. in 'murica... There are so many options: stem risers, 45 deg stems, if in the budget, a "tall headtube" road bike ( takes the new tittle of "old guys road bike", which used to describe a flat bar road/hybrid bike ) ... or even a custom frame.

A friend of mine was told ( by a doctor ) he cant ride his bike anymore cause of prostate issues ... I had 3 words for him " Selle Italia Superflow."
