Hi! A relative has asked me to help get him a mountain bike, and I know nothing about them! He wants a bike that can be used on and off road, and he seems to be partial to Japanese brands. He gave me a brochure for Shimano, but seems that they only make components?!? I have no idea what I'm looking it, so could anyone offer some advice? Also, budget is NOT an issue! He wants to go all out on this bike! Any help would be greatly appreciated. Thanks!
