Help for a novice please. I've just started riding but rather than spending a lot of money on a new bike I opted for a used one [just in case I lost interest]. I'm 6ft 3in and the bike I have is an XL. What I would like to ascertain is if I have the bike set up in relation to my various body parts legs, arms, reach etc, correct. I've been unable to locate a suitable website/page which gives me the ideal set up of a bike in relation to my size. Any assistance would be appreciated.
