Specs

29"/27.5"+

New for 2018 is the Surface Ti. Chromag’s first ever Titanium hardtail! The Surface Ti mirrors the geometry of our highly evolved Surface model featuring our most updated design, tuned for all mountain capabilities with rugged trail riding as the priority. As per the evolution of all our trail bikes the Surface Ti features long front end geometry, slacker head angle, steep seattube angle, short chainstays, and low bb height, all tuned for longer travel (150mm). This frame is designed with 148 boost rear axle spacing and a new yoke, cnc machined from solid titanium for increased tire clearance.

Features

Head tube badges

Bikes are special. The headtube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our headtube badges have changed over the years and are an indication of the time each bike was made. Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.

Yokel

Our ‘Yokel’ design is a small machined junction on the chainstay that helps accommodate both tire clearance and chainring clearance. Our first versions were huge CNC yokes that bridged the entire front end of the chainstays. Over time we refined this to minimize weight by arranging our chainstay layout asymmetrically and reducing the yoke to a minimal size. It’s one of our most unique frame features and has been copied by other frame makers.

Tubing

The weight savings, feel and raw beauty of titanium with the performance and reliability of chromoly. This bike has been years in the making. We wanted to match the performance of our evolved steel designs with tubing manufactured to our own specifications. Off the shelf titanium tubing was not an option, nor was stock dropouts, junctions or cable guides. The Surface Ti is comprised of components and tubing made entirely of our own spec.
