Our Praxis TT Road Chainrings are the result of relentless testing and tweaking, matched with the best material and manufacturing processes to create some of the smoothest running, most durable and sweetest shifting Chainrings available. These TT Rings are machined from 7075 T6 Aluminium and hard anodized for even more durability. They also feature our famous LevaTime Shifting Technology, which boasts synchronized ramps and strategically placed shift pins for perfectly timed shifts every time.
PLEASE NOTE: Chainring Bolts are NOT included.
SHIMANO – Our Praxis time trial chainrings work great with the new Shimano 10/11sp chain and drivetrains (Di2 included) when mounted to a traditional 5-arm mount 110 or 130 BCD Shimano crank. They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks… *Our chainrings do not mount to the new DA9000 crank with its new custom asymmetrical BCD.
SRAM – Our chainrings work great with the SRAM 10sp and 11sp drivetrains when mounted to a traditional 5-arm mount 110 or 130 BCD SRAM crank. They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks.
EXOGRAM RED/FORCE/RIVAL CRANKS – Our rings are not made for the brand new SRAM ‘Exogram’ cranks as they are a custom 4-arm mounting. -YAW FRONT DERAILLEUR – Our rings shift great with the new SRAM “Yaw” front derailleur.
CAMPY – Our rings work great with Campy 10/11sp chain and drivetrains (EPS included) when mounted on a traditional 5-arm mount 110 or 130 BCD crank such as a THM, Rotor, Cannondale, Specialized, LOOK, FSA crank. Our rings DO NOT mount to Campy cranks.
LEVATIME – Our LevaTime shifting is the product of years of relentless testing and tweaking. The final result is a set of some of the finest and fastest-shifting rings available. With a LevaTime ring, several custom shift pins are placed strategically at points on the ring to provide a perfectly timed lift. Synchronized ramps are tuned with a specific inner ring, providing a clean channel for the chain to move upwards. Each individual tooth is sculpted to handle a specific duty. Along with that, the Praixs time trail chainring’s precisely located scallops help control chain movement and prevent chain suck.
