Surface 27.5+" / 29"
Never wonder if you have the right bike
Big wheels, all mountain
The Surface features longer front end per sizing, slacker head angle, steeper seattube, shorter chainstays, and bb height adjusted for longer travel (150mm). We are now using 148 boost rear axle spacing and a new ‘yokel’ layout for increased tire clearance. The Surface is a 29er but will also accept 27.5+ tires up to 2.8” or possibly more.

29 x 2.5” or 27.5 x 2.8”

Chromag custom 4130 chromoly steel alloy, drawn to our own specifications for each model.
Head Tube Badge
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.
Making modern chromoly frames is challenging when most of the tubes available on the market are from an era of mountain biking long past. After several years of frame production we reached the point where we could design and produce our own custom tubing for the majority of our frame tubes. This contributes to the unique look of many of our frames but more importantly allows us to configure our bikes exactly as we want for each design.
As 12mm through axles have proven to be solid, reliable and convenient, we have committed most of our models to utilize this format. Our 12mm dropouts are accurate and tough and feature a removable derailleur hanger with a sturdy interface for strength and reliability. All 2017 models (excluding Monk and Nice Dreams) will follow the 148mm boost spacing.
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.
