Speedfox SF02/Shimano Deore-SLX Complete Bike - 2012

The BMC Speedfox SF02/Shimano Deore-SLX Complete Bike - 2012 is built to be a faithful companion that’s happiest when you take it on the trail. It takes the efficiency of the race-oriented Fourstroke, and gets an extra inch of travel, as well as a more cost-effective aluminum frameset. The result is a bike that’s highly efficient, yet comfortable enough for all-day rides.

The SF02 uses a triple-butted, hydroformed alloy tubeset. BMC's iSC (integrated Skeleton Concept) optimizes weight savings, strength, and ride characteristics by using Finite Elements Method (FEM) computer technology. Every 6000-series aluminum tube is shaped to exacting standards; what you get is a frame that reacts to rider inputs like power application, steering, and braking with impeccable efficiency and precision. BMC's extra attention to tube shape results in a frame that maximizes weight savings and stiffness.

Stroke is controlled using BMC's patented Advanced Pivot System rear suspension. It's essentially a mini-link rear suspension that creates a floating pivot. The forged aluminum links are purposely short to eliminate unwanted lateral flex, and they provide a union between the front and rear triangles using sealed cartridge pivot bearings. The placement of the upper and lower linkages creates a fine balance between bump sensitivity, stability (resistance to bobbing or effect from rider weight shift), and their desired leverage ratios. And by positioning the floating pivot relative to the chainrings, the APS suspension maintains the efficient pedaling characteristic that world class riders demand from a high-performance trail bike.

The Speedfox offers 120mm of race-ready rear wheel travel damped by a Scor shock. It's air sprung and has an external adjustment for rebound damping. The APS rear suspension is active throughout the travel range, accomplished by BMC's insistence on a nearly linear wheel rate. So although you'll get a suspension that is tuned for maximum acceleration and traction, it still yields the full 120mm of travel when you need it. The net result is a bike that soaks up bumps beautifully whether you’re at full gas, coasting, or braking.

This particular SF02 runs on a Shimano Deore drivetrain, with the exception of an SLX rear derailleur. Avid Elixir 1s keep your speed in check. Suspension duties are handled by a Scor rear shock, and a Rock Shox Recon Gold TK fork. Scor supplies the stem, handlebar, seatpost, and saddle. The wheels consist of Shimano hubs, laced to Alex XD-Comp rims, wrapped in Schwalbe tires.

The BMC Speedfox SF02/Shimano Deore-SLX Complete Bike - 2012 is available in four sizes, from Small to X-Large, and in the color Black.
