Hi everyone! Hope this is the right place to post this. Thinking about buying a road bike, but really don't know what kind. I do some mountain biking, but I'm fed up with all the mud from the crap weather so I guess I need something more appropriate for tarmac. I know nothing about road bikes so any tips would be gratefully received. What sort of money do you need to spend to get an ok road bike? How much faster will I go on a road bike compared to a mountain bike? Thanks guys (and gals).
