The Sram GX 1400 GXP is the crank set from the GX series by Sram. The GX series should make riding with a 11-speed accessible for everyone. You can choose between a single or a double crankset. With the double crankset you can have the largest range with a 11-speed (10/42)! Through X-Glide chainrings you can change gears with a perfect timing in all conditions.
With the single version you run 32 teeth on the chainring. The X-Sync chainring ensures that the chain does not jump from the chainring.
The 1400 series is lighter than the 1000 series due to the use of aluminium and an other milling technique.
