4 Spoke carbon wheel: The original monocoque wheel model
The 4 Spoke carbon wheel is the worldwide reference of monocoque carbon wheels.
Created from the beginning to be a versatile wheel, it is perfect for road use (time-trial and triathlon) and for track use thanks to its excellent lateral stiffness.
The rear road cassette 4 Spoke wheel can also be used for track (for cyclists who sometimes ride on track), thanks to the specific preparation of the wheel in the Corima workshops and the purchase of the rear "Road to Track" converter kit (ref: 400115).
The 4 Spoke wheel is produced in 2 versions :
- Model HR is composed of High Resistance carbon fibres for strength, developed for triathlon and road racing.
- Model HM is made out of High Modulus carbon fibres. It is perfectly adapted to all track events and to powerful athletes?
The 4 Spoke carbon wheelset does not require any particular maintenance thanks to its monocoque structure.
 |
The indicated value is the weight of the front tubular wheel in 700C (28") without the skewer. |  |
The HM models of our 4 Spoke wheels are made of HM carbon fibre (High Modulus), approximately 20% more rigid than the HR model, perfectly adapted for road racing and track events. | |
 |
The 4 spoke carbon wheels are supplied with an integrated magnet in one of the spokes (indicated by a sticker) for use with most modern bicycle computers. |  |
The HR model of our 4 Spoke carbon wheels is composed of HR carbon fibre (High Resistance), developed for road racing or triathlon | |
 |
The rear CORIMA wheels for road are compatible with Shimano 10 speed cassette(Hyper Glide), Campagnolo 9/10/11 speed cassette (Exa Drive) or Shimano 8/9/10 speed Sram cassette (Hyper Glide). The complete cassette body is interchangeable. |  |
The carbon's appearance in 12K is highlighted by a more visual weave, each square weave is made of 12000 filaments. | |
 |
For safe and better braking, you must use the brake pads that have been specifically designed by CORIMA for use on carbon rims. Our brake pads are compatible on Shimano, Campagnolo and Sram brake shoes. |  |
New design of the rim's profiles to 22.6 mm which increases its stiffness and minimizes the air drag for better aerodynamics. | |
 |
This technology used on some of our tubular carbon wheels increases the rim's stiffness for better performance. |

(1) For tubular rims, CORIMA recommends 23 mm tubular tires and for clincher CORIMA recommends 23 mm clincher tires.
(2) Rims weights are given as an indication. Weight without skewer
(4) There is no maximum air pressure for tubular wheels except the one recommended by the manufacturer of the tubular tire you're going to set on your wheel.
(5) Front road wheels can be used for track by removing the quick release skewer and setting track bolts (ref: 400161) on each side of the axle.
(6) Monobloc rear road cassette wheels (4 SPOKE and DISC) can also be used for track thanks to the specific preparation of the wheel and the purchase of the rear "Road to track"
(8) Supplied with 2 rear track blocking screws
