Designed for epic days on epic terrain, Big Mama is our four inch travel, 29?er trail bike.
Crafted of custom-drawn scandium tubing, we?ve done our best to design an all-day bike that feels just right, rides just right, and looks?well, pretty damn sexy.
Big Mama uses a single pivot, flexing seatstay design to activate a custom- tuned Fox RP2 air shock. Most importantly, the seatstays act not just as a frame member, but also as an integral part of the suspension design.
At proper sag, the tuned seatstays provide resistance to pedal-induced bobbing while still remaining sensitive to small bump forces. On larger hits, the flexing seatstays work with the linkage to assist the rear shock in moving through its full stroke.
Use of the flexing seatstays also eliminates the need for a rearward pivot. This increases stiffness in the rear triangle. It also lessens stress on the frame?s remaining pivots and bearings and increases durability.
In an effort to keep your wheels where you want them, lateral stiffness has been maximized through tube butting and shaping, removal of the rear end pivot, a one-piece linkage, and the use of large weld areas in critical places.
Some say it is all in the details: Seven forged parts per frame add strength while keeping the weight down. Fantastic standover clearance encourages the rider to tackle tough terrain. Size-specific cable routing keeps it all clean and appropriately out of the way. Mud clearance abounds even with 2.4" tires. The direct mount, post style disc brake mount offers adaptor-free caliper mounting with 160mm rotors.
Big Mama. Sometimes bigger is better.
