I've watched the youtube manual/drop off lessons and damn it I just can't do them!
I'm 5'9" but have a long torso and short-medium legs and arms.
The bike is a 28" Carrera Vulcan, I assume that's decent enough for the problem not to be that the front of the big is just too heavy?
I also feel my breath is constricted due to being hunched over.
Do you think I should move down to a 16" frame? Halfords say that's only relevent for people 5'1"-5'6".
