Description
Rims
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.
Hubs
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.
The Sign of Quality
All Kronostok models have undergone and passed the rigorous testing procedures necessary to be awarded UCI approval. This listing allows their use in all UCI (road), ITU & ETU (Triathlon/Duathlon) drafting events which has become increasingly important to many Age Group Triathletes as well as competitive road riders. Kronostok wheelsets come with a 2 Year mechanical warranty (excludes ware and tear such as bearings).
