This construction not only ensures a low overall weight, it provides a strength and stiffness far beyond any sold forged type. The GX 1400's X-SYNC™ chainring provides unrivalled durability and chain retention even over the roughest terrain and clears mud well thanks to specific recesses, so you can blast through anything with no drop in performance. X-Sync: 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. Open Core: To fabricate the Open Core Technology a single mass of premium alloy is pushed, pulled and squeezed into a hollow crank arm producing supreme strength while remaining weight-conscious.
