Technology

BB30

Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.

GXP®

GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.

PressFit™

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.

X-SYNC™

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.

SRAM X01 DH and RockShox BoXXer voted ‘Best of Vital top 10 products for 2015′

“When SRAM’s XX1 drivetrain appeared a couple of years ago now, it was nothing short of a revolution, and certainly not just because it goes to 11…lighter, quieter, more reliable, and easier to operate. The obituary of the front derailleur was short and to the point: “so long, and good riddance. It turned out to be everything we had hoped for and then some, simplifying the drivetrain and making shifts count when every millisecond can make a difference.”

SRAM X01 DH Review on Pinkbike.com

“Shifting across the cassette feels extremely positive, even compared to SRAM’s other single-ring groups, and the 10 – 24 spread felt spot on for use on a downhill bike…but it was pretty obvious to me that I was shifting less than I would be if I had another three or four cogs, and when it comes to a downhill bike the less shifting the better.”
