Halfway through the World Cup season marks a tipping point where teams start to pull out all the stops to play catch up or stay on top. The NS Bikes UR Team has brought along their new secret weapon: a prototype Fuzz with a six-bar suspension design, similar to what Commencal is using on their Supreme V5
. NS Bikes is calling this linkage system a "floating high pivot design" and it provides 203mm of travel and is built around a dedicated mixed wheel setup. Team members Kye A'Hearn and George Brannigan will be unleashing the bike on the blazingly fast Andorra World Cup track this weekend since they feel it's a beneficial place to test the bike to its full capacity.
The prototype bike appears similar to their current Fuzz, in its stealthy black veil, until you take a closer look and what's going on behind the seat tube. Deviating from their classic four-bar suspension system, they've added a short link between the main triangle and the chainstay, while keeping the pivot near the rear axle. A bridge connects from that short link near the bottom bracket to the middle pivot of the upper rocker arm. Interrupting the upper chainline between the cassette and the front ring is an idler that hangs from that rate controlling bridge. On that bridge, there are slots to move the idler vertically to tune the influence of the chain on the suspension. You might also notice that they are still opting to use the O-Chain device to reduce the pedal kickback, a component that is now widely used in both downhill and enduro racing.
