This construction not only ensures a low overall weight, it provides a strength & stiffness far beyond any sold forged type. The GX 1400's X-SYNC™ chainring provides unrivalled durability & chain retention even over the roughest terrain & clears mud well thanks to specific recesses, so you can blast through anything with no drop in performance. Technologies: X-SYNC™ - 1x chainrings provide the highest level of performance & durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp & narrow tooth profile & the rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chainrings have been designed with mud-clearing recesses for the inner chain links & rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1x™ drivetrain. OCT (Open Core Technology)™ - To fabricate Open Core Technology a single mass of premium alloy is pushed, pulled & squeezed into a hollow crank arm. During SRAM's exclusive process the magic happens, producing supreme strength while remaining weight-conscious. SRAM may have not been the first to fabricate hollow crank arms, but they are the best by yielding the highest stiffness-to-weight ratio out there. OCT cranks are stiffer, stronger, & lightweight beyond any solid forged crankset & when with the use of SRAM'S AL-7050-TV to fabricate with OCT the results are impressive. BB30 - Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability & stronger crank construction. ...

Featuring SRAM’s X-SYNC™ tooth profile, the GX chainset is engineered for complete chain control. Each tooth’s thickness is CNC machined to work seamlessly with the chain’s inner & outer links. & with five available chainrings, you can personalise your gear range to match the way you ride. BOOST148 BOOST148 (hub width 148mm x 12mm) is targeted at 29ers & is designed to increase wheel stiffness via the hub. The hub flanges are slightly wider apart from standard hubs (142mm x 12mm) & according to SRAM & Trek "this small increase in width results in significant gains to rear wheel stiffness — comparable to a 27.5in mountain bike wheel". ...
