All Kronostok rims use blunt trailing edge profiles which are now widely recognised as the fastest performing all round shape. Bunt profiles create a more balanced shape which results in superior handling characteristics, allowing deeper rims to be ridden with a lower interference from gusting crosswinds.
Braking is powerful due to the use of high temperature resistant resins and the addition of a hard wearing Basalt layer into the brake track surface, giving a rider confidence to attack even the most technically challenging races and routes, in wet or dry conditions.
New for 2020 is the use of our Revolver 321 hubset which has been designed to use a 2:1 ratio spoke build configuration to the rear wheel. 2:1 referring to the use of two spokes on the drive side to every one on the none drive resulting in less flex due to a more equal tensioning throughout the wheel.
Spokes – We use high quality Pillar PSR X-TRA Aero. A great combination of strength, lightweight and of course aerodynamics.
