Praxis - CR - 130 BCD Aero TT

The 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 the 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.Features

SHIMANO - The Praxis time trial chainrings work great with the new Shimano 12sp chain and drivetrains (Di2 included) when mounted to a traditional 5-arm mount 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 *the chainrings do not mount to the new DA9000 crank with its new custom asymmetrical BCD.

SRAM - The chainrings work great with the SRAM 12sp drivetrains when mounted to a traditional 5-arm mount 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 - The rings are not made for the brand new SRAM Exogram cranks as they are a custom 4-arm mounting. -YAW FRONT DERAILLEUR - The rings shift great with the new SRAM Yaw front derailleur.

CAMPY - The rings work great with Campy 12sp chain and drivetrains (EPS included) when mounted on a traditional 5-arm mount 130 BCD crank such as a THM, Rotor, Cannondale, Specialized, LOOK, FSA crank. The rings DO NOT mount to Campy cranks.

LEVATIME The 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.

Press

Cycling PlusThey worked as quickly and smoothly as Dura-Ace or SRAM Red and better than older drivetrains or those outside of the big three. Pick-up is instant, and even though we tried to upset things by climbing at full power on the big ring and suddenly shifting to the small ring, and by shifting when riding inadvisable chain lines, the Praxis setup stayed resolutely smooth and glitch-free. we found chain retention with a 9-speed Shimano chain perfect, the drivetrain running as quietly as it ever had.Pricing is competitive, and Praxis has delivered a great alternative if youre looking for a drivetrain upgrade or to change gearing.
