SRAM's new X01 eleven-speed ensemble looks and performs like XX1 - but at a significantly lower retail price.
The aluminum X-Sync crankset uses a 94-millimeter bolt circle and will fit many bash guards. Like XX1, X01 chainrings use SRAM's profiled teeth that interlock with the chain's side-plates and help to keep the chain on when the pace is furious. X01 also needs a dedicated 11-speed chain, and it gets a slightly heavier one than XX1, but with the addition of a super-durable hard-chrome finish.
X01's 'X-Horizon' rear derailleur can be had with an aluminum or a carbon cage, and it shares both XX1's zero-slant parallelogram, and its Type-2 clutch system. The cassette is new for X01 and while it has the same gear ratios as XX1, the X01 cassette will be hard-plated with a black surface treatment and will weigh 275 grams compared to XX1's 260 grams. XX1 cassettes are designated XG1199, and the X01 is XG1195.
Like XX1, the X01 cassette requires the new XD freehub design, which is readily available from top wheel and hub makers now. Production X01 cassettes will be all black with a special surface treatment.
Shifters are available in trigger or GripShift, with both items being nearly exact copies of XX1, which means that the triggers are Matchmaker compatible and the thumb lever is angle-adjustable. Both shift options will interchange with XX1.
