i've started to get some lower back pain, but £200 is a lot of beer to forego. are there any slightly less scientific but almost as useful recommendations out there that you would trust: e.g. bikeshops that can check your position on a bike and make suggestions?

please read some of the other threads on this topic

lots of information is available

simply put you spend the money now in one go, or spend the money piecemeal slowly tweaking your bike and have the additional costs of physiotherapy until you get the bike to fit you

you get what you pay for

there are various rules of thumb to setting up bikes but if you cannot get it right yourself then you may wish to pay a professional
