Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. Which is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs and RockShox forks.
GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.
A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter.
- Pressfit 30™
This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching.
SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.

"In conclusion, it’s still the same old drivetrain system we have had since the late 1800s, but XX1 is its biggest evolutionary step forward in a long time. It is simple, silent, reliable and rather resilient to real world use. All things you don’t normally expect from a boutique drivetrain. In short, I would find it hard to go back to anything else now.”
Huffington Post's Max Gladwell recently completed the Point-to-Point 80-mile Singletrack race in Utah focused on reviewing the new SRAM RISE 60 Wheels, SRAM Guide Ultimate brakes, SRAM XX1 Quarq equipped drive train and RockShox RS-1. In nearly 8 hours of non-stop racing that descends and ascends over 10,000 feet ranging from 7k to almost 10k feet he gave much praise to our products for getting him through.
The German Enduro Magazine published a long-term test about the SRAM 1x11 drivetrain. With each of these group sets having ticked off several thousand kilometers on their test fleet, they thought it was time to see how they were faring. The 1x11 drivetrains have been out on all terrains for serious testing - from the Bavarian mountains to the flowing trails around Stuttgart, and not forgetting the filthy wet lines of Scotland
