Praxis Chainrings

"Praxis ChainringsNot all chainrings are created equal, and if you need proof of this, look no further than these chainrings that Praxis made exclusively for us. Their custom design revolves around a cold forged and hard-anodized 7075 T6 Aluminium that's incredibly stiff and very respectable in the weight department. Shifting between rings is also smooth and precise, as Praxis included several elevators and specially tuned ramps around each ring.Custom design Praxis rings made exclusively for Specialized.Cold-forged, Heat-treated, and hard anodize 7075 T6 AluminiumCompatible with Campagnolo, Shimano, and SRAM 10-/11-speed cranksets.110 BCD."
