Geometry & Sizing
Our internal cable routing system feeds cables through the bike frame keeping them protected from stray branches along the trail and any other bumps or snags the bike could come into contact with along the way. Inserts plug openings in the frame to keep water and debris out while firmly holding cables in place.
We’ve extended the top tubes and decreased the length of our stems on our trail and all-mountain models
positioning the rider perfectly in relation to the wheelbase for the most balanced riding position possible. Shorter stems allow
the effective reach to remain the same when combined with the lengthened top tube, all while providing more responsive steering.
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.
