What makes a great climbing bike?
Okay we all know that wheels/tires combo, a weight weenie bike and not to exclude the engine riding it makes any bike climb hills better. But what else is there on a bike that makes it a good climber? My guess is probably the frame geometry and stiffness in places that matter. So where are these magic areas? Is it shorter chain stays, shorter wheel base, huge BB etc? By looking at a geo chart, what would give me an indication its a good climbing bike, if there is such a thing? What characteristics do the pros look for when riding long and steep climbs? Just wondering...
