Triple Triangle Design

Avalanche's seatstays have been decoupled from the seat tube to give a ‘floating’ connection between seatpost and rear axle, making it 50% more vertically complaint than a traditional double diamond frame for additional comfort.

Internal Cable Routing

Routing the cables internally through the frame gives Avalanche a clean and sophisticated look while decreasing snag points. It also allows for a dropper post to be easily installed for a better descending experience.
