2017 BMC Trailfox 03 X1 Bike
Aluminum frame, SRAM X1 drivetrain, Shimano SLX brake, the BMC Trailfox 03 X1 Bike is the bike that packages BMC’s offroad mastery of big, rough mountains in a way that anybody can swing a leg over.
Trail access is the goal. For one, it’s an enduro bike that climbs like a sprightly XC rig. For another, the build is designed to get you out the door for the least impact on your wallet. And, you can take this wherever you go, and be ready, willing, and able to take on all the action that daylight allows.
Let’s tackle the second item first. The 03 takes the design of the Trailfox 01 and executes it in triple-butted, hydroformed aluminum. BMC takes all those shapes and either gets them exactly the same, or as close as possible given the constraints of the material and hydroforming technology. Yes, it’s a bit heavier, but it is also much less expensive and more durable.
It has all the manners of the 01. Thanks to the Big Wheel Concept, low bottom bracket, short stays, long top tube, short head tube, it climbs like few 29ers. And thanks those same features plus a shallow head tube angle, it descends like nobody’s business. BMC’s Advanced Pivot System, APS, sets you up so you can pedal and still have an active suspension. The linkage helps separate pedal-induced forces from trail-induced forces. And you have 150mm of travel, with a Cane Creek Inline DB Air R shock presiding over the controls.
The gearing is SRAM’s X1. You start with the X1 crank with a 30-tooth chainring. Then the X1 X-Horizon rear derailleur shifts over a 10-42 eleven-speed cassette.
Stopping is courtesy of Shimano’s SLX hydraulic calipers. They stop 203mm rotors secured to BMC-built wheels. These feature SRAMS MTH-716 hubs and DT Swiss’ E512 rims. BMC wanted to deliver a durable, high-performing wheel without the price of a fancy set, so they assembled their own. Thru-axles front and rear keep both suspension elements laterally rigid, and Onza tires keep you firmly attached to the trail. They feature the Ibex tread, front and rear, with their Freeride-friendly FRC casing. The tires are in the 2.4” width.
The fork is RockShox Pike RC Solo Air 160mm. Again, think simplicity with only two adjustments, the Solo Air shock and charger damper. The 35mm stanchions, when paired with the thru-axle, are oversized, light, and stiff. Keeping with the theme, the steerer is tapered from a conventional 1 1/8″ to a massive 1 1/2″.

A dropper post is included, with 125mm of travel to get down. A Fizik Nisene XS saddle tops it off.
The Trailfox 03 X1 Bike brings the best of BMC’s trail tech down to a price everyone can love.
