Bike Crankset 1x12 Speed 30T 170mm DUB Wide Boost Chainring for MTB

DESCRIPTION

Quality and durability combine in the SRAM X1 crankset to deliver consistent performance every time out.
Featuring the X-SYNC 2 tooth profile chainring for complete chain control. Each tooth's thickness is machined and controlled to work seamlessly with the chain's inner and outer links. DUB technology’s patented spindle design and bottom bracket provides a uniform approach to fitment, better sealing and forward and backward compatibility. 

These cranks provide a 55mm chainline which is compatible with SuperBoost 12x157mm rear hub bikes, but also compatible with newer Boost 12x148mm bikes to allow the use of larger than spec chainrings or to fine tune your chainline.
