I'm looking around at getting a FS bike to go along with my hardtail. I've been comparing geometry on a bunch of different bikes. My hardtail has a bottom bracket height of 11.5 inches by the original specs. I was hoping to get a little more bb and pedal clearance on the FS rig, so I'm wondering what I need to shoot for. They don't really compare directly because of rear suspension sag and travel, right?
