Successor of the DH07, Stoy is the new damper BOS descent. Even more successful than its predecessor, it is changing especially in the design. It will be using a new head piggy-back, and a shorter tank. The entire block compression adjuster is also completely new. Finally, Stoy receives mounting rings bearing needles, a luxury previously reserved only for shock absorbers “factory” for Nicolas Vouilloz. Advantages of the system: a game reduced to nothing, and a very long lifetime compared to the du-bushing usually used.

Like all BOS dampers, Stoy is fully adjustable and rebuildable.

Available for most bikes down the market, in the usual standard lengths, it may also be delivered in extras and race one-off sizes upon request.
BOS also uses springs in 25lb increments to also aid in dialing in the perfect spring.
