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.
