ok, maybe that's too much difference for what i want. my brother wants a new bike but he wants to go down the tow paths sometimes. i suggested a hybrid, something like the sirrus, but it's too girlie apparently. what he is really trying to say is he wants drop handlebars. so i suggested a cyclocross/tricross. i had a quick moozy round on t'internet last night and they seem to start from about £690, but he has £500 at a push.
So would a road bike with tougher tyres be ok for him?
