S3 FEATURES

Collapse

BBright

This asymmetrical 79mm bottom-bracket standard yields stiffer and lighter frames and crank systems.

Collapse

Carbon Dropouts

Tough, compression-molded dropouts save weight with no sacrifice in strength compared to traditional metal dropouts.

Collapse

Dropped Down Tube

Reduces drag by treating the front wheel and frame as one aerodynamic shape.

Collapse

Evolved Steerer Design

The fork steerer’s diameter has a noticeable effect on a bike’s handling. Evolved Steerer Design applies the diameters and taper designs that best suit each model.

Collapse

Future-Proof Cable Management

Ensures your frame is compatible with all current and future derailleur and brake systems.

Collapse

Partial Seat Tube Cutout

A close-fitting curve in the seat-tube’s trailing edge improves aerodynamics by partially shielding the leading edge and top of the rear wheel.

As with the Extended Seat Tube Cutout, the frame must fit closely to the tire, and the seat-tube cross section must have the right shape to help air flow smoothly across the seat-tube and around the wheel. Compared to the extended cutout, the partial version gives up a bit of aero to save a little weight.

Reduced-Friction BB Guide

Significantly reduces cable friction in the bottom bracket, which means smoother shifting, easier setup and longer service intervals.
