Sram GX 1000 GXP crankset

The SRAM GX crankset delivers consistent performance every time out. Featuring SRAM?s X-SYNC? tooth profile, the GX crankset is engineered for complete chain control. Each tooth?s thickness is CNC machined to work seamlessly with the chain?s inner and outer links.


Features:

- CNC machined 7075, two-tone anodized X-SYNC? chainring?an integral component of the SRAM 1x? drivetrain
- Our Open Core Technology (OCT?) cranks are stiffer, stronger, and lightweight beyond any solid forged crankset.
- X-SYNC? tall, square tooth design provides maximum chain control
- Sharp, narrow tooth profile and rounded chamfer edges help manage a deflected chain
- Mud-clearing recesses for the inner chain links and rollers
- Chainring guard option
- BOOST 148 compatible
- Fat bike crank option

Technology:

BB30:
Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.

BOOST:
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®:
GXP?s Gutter Seal design cuts friction and weight?improving both feel and performance.

OCT (Open Core Technology)?:
To fabricate our Open Core Technology a single mass of premium alloy is pushed, pulled and squeezed into a hollow crank arm. During our exclusive process the magic happens, producing supreme strength while remaining weight-conscious. We may have not been the first to fabricate hollow crank arms, but we are the best by yielding the highest stiffness-to-weight ratio out there. Our OCT cranks are stiffer, stronger, and lightweight beyond any solid forged crankset and when we use our AL-7050-TV to fabricate with OCT the results are impressive.

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.
