Hi Guys, looking to buy my first downhill bike and was wondering what size bike I should be looking at. I'm about 6ft and weigh about 87kg. There seems to be plenty of 2nd hand medium bikes around but I'm thinking a large would probably be more suitable. Been to a few shops and have been told a medium would be OK but others have said definitely large. Don't know what to believe. Any advice is much appreciated. Cheers, Adam.
