Mountain bikes, in general, have been moving towards fatter tires and wider spacing for some time now as the industry as a whole continues to adopt new standards. Commencal’s most recent addition is keeping with the trends by offering a 650b plus sized all-mountain bike. The Supreme SX is centered around having fun while going up and down hills; though its 180mm of travel and slacked out head angle may put slightly more focus on the latter. Similar to others in the industry the SX is built around Boost spacing, while its chain line and suspension design are another story. Check out the specs, geometry and pricing after the break…
Commencal Supreme SX Frame & Geometry
Commencal claims that by using a high pivot point (left) the Supreme SX delivers more stability and grip while increasing pedal efficiency. Further, its unique chain line wraps around the main pivot to negate any impact the chain could have on its suspension. The frame is built with ISCG tabs, a 31.6-mm seat tube, internal cable routing, press fit BB92, Boost spacing (148 x 12 rear: 110 x 15 front) and a triple-butted aluminum construction. Bikes come in complete builds and frame only options. Individual frame sales include frames with and without rear shocks. The claimed frame weights are 4kg (w/o shock) and 4.6kg (w/ shock). Provided weight on the complete bike is 15kg. Despite the yellow diagram, the Supreme SX is only available in black and orange colors, and in sizes ranging from S – XL (availability may vary).
Commencal Supreme SX Build & Price
The Supreme SX gets a Sram 1×11 GX drivetrain and Guide RE brakes on 200mm rotors. A Rockshox Lyrik fork and Super Deluxe RC3 rear shock offer 180mm of travel front and back, while a Reverb Stealth dropper allows easy on-the-go adjustments. Also, an integrated downtube guard protects the frame from rocks and debris while a chain stay guard dampens chain slap. Stock tires include Maxxis HRII 650 x 2.4 up front and the DHRIII 650 x 2.3 in the rear. Frames without a rear shock are priced at $1,500, while a frame with the shock will go for $1,900. The complete Supreme SX builds have current prices of €3,700: $3,700 US: $4,800 CAD.
