Geometry & Sizing
Free Floating Technology suspension allows the rear shock to float with the rocker link and the rear triangle. Traditional
shock mounts are hard mounted, meaning the rear shock engages when the rocker link is activated. With the FFT suspension system both the chain stays and rocker link engage the shock and move fluidly. This allows Mongoose to fine-tune the suspension to offer a supple and progressive feel for the rider.
Our adaptable drop outs utilize machined aluminum inserts to convert from our standard 141 mm QR hub spacing to the stiffer 148 mm spacing, 12 mm thru axle hubs. It’s another way that Mongoose is giving you the best bang for your buck; the right ride at the right price at the right time.
T2 Tectonic Aluminum
Aviation technology in a bicycle frame. With a 50% increase in strength and 30% decrease in weight when compared to our T1 aluminum, Tectonic T2 aluminum brings aircraft quality to your ride without compromising on overall frame stiffness.
