Yesterday i was quoted £120 for a basic bike setup (saddle height, bars, pedal position etc) which i think is a rip off.

Do people tend to do their own set up and if so what guides are best for this ?

Only doing 30miles a week on average so no pro but do get some lower back pain so suspect my set up is slightly out somewhere.

TIA,
Mike.
