Is it worth getting a proper bike fit? I mean, there are probably lots of people out there riding about quite happily and never had a proper bike fit. The reason I'm asking is now that I have bought (in the correct size!) a Bianchi which is a bike I've always wanted and I'm in the process of buying an adventure bike, is it worth getting a proper bike fit. Also, do the fit measurements apply universally to all bikes that a person may purchase in the future?
