Praxis Works Buzz 130BCD TT Chainrings

Praxis Works Buzz 130BCD TT Chainrings Aimed squarely at those pushing themselves to the limit in time trials; the Praxis Works Buzz 130BCD TT Chainrings have been systematically developed by Praxis Works to give long-lasting service and great shifting with either 10 or 11-speed drivetrains; whether mechanical or electronic. These chainrings are designed for five arm cranks; with a 130 bolt circle diameter (BCD) meaning that the large chainrings are fully supported for stiffness; helping both power transfer and shifting performance. A series of ramps and pins move the chain across chainrings quickly and accurately every time a shift is called for; even whilst under load; and the scallops help control the chain movement and prevent chain-suck. Please note that the Spider is not included.
