Details, details (clockwise from top left): the rear stays offer gobs of tire clearance--and also comes with a handy sag indicator. Note the asymmetrical nature of the seat tube as it descends toward the bottom bracket--the shape and the additional material stiffen both work to alleviate lateral flex in this critical area. The frame will also mount a chainguide to the ISCG 05 tabs on the underside of the bottom bracket shell. This is the same frame as the Zesty, so it's also set up to accommodate a front derailleur (thoughtfully mounted to the chain stay). Every single one of the pivots holds two oversized bearings held in place with a low torque collette system (as the retaining bolt is screwed in, a wedge expands, locking everything together).
