NEW REAR END
In a focused effort to make the Epic, hands down, the fastest XC bike out there, one of the main goals was to drastically reduce weight. In doing so, we removed pivots from the rear end of this new platform, and that decision saved us 240g (39% lighter) in the rear end alone. This, in combination with the new Brain, allowed us to make large improvements in overall performance, while also saving up to 525g in some frames. You can say that the new Epic is a single-pivot bike. We've designed engineered flex zones in the chain and seatstays, however, to emulate the performance of the FSR system. Being designed around a 1x drivetrain, our engineers were able to tune the platform to perform better under pedaling forces. And combined with the sensitivity of the new Brain, the Epic builds on the efficiency of its predecessor.
Removing pivots also makes for a stiffer rear end, and of course, this means better power transfer efficiency. We very much believe in the FSR system as an effective an efficient suspension design, though, so you'll continue to see it throughout the rest of our mountain bikes.
