The Sram GX 1400 BB30 is the crankset from the SRAM GX serie. The GX series makes riding with a 11-speed accessible for everyone. You can choose between a single and a double crankset. With the double and a 11 speed cassette (10/42) you have the largest range ever on a double crankset! Thanks to the X-Glide chainrings you can shift with a perfect timing in all conditions.
With the single variant you have 32 teeth on the chainring. The X-Sync chainring ensures that the chain does not jump from the chainring.
