Seatpost diameter27.2 mm
Diameter27.2 mm
Typical classthe de facto standard on modern road and gravel frames, and many hardtail and lightweight full-suspension frames

The Trek Emonda SLR runs an integrated IS42 upper headset with a 28.6 mm steerer, a 27.2 mm class road seatpost interface, a 12x100 front thru-axle and a braze-on front-derailleur mount.

The 27.2 mm figure is the mainstream disc-road interface; Trek's own aero posts are proprietary in shape, so confirm the exact Trek post part. The bottom bracket on this frame is a threaded T47 shell, covered on its own page.
