A carbon rim, precisely tensioned spokes and a reliable hub. IDEA wheel quality comes from how they work together — from development and measurement to hand building and long-term servicing.
Aerodynamic and deformation simulations help compare rims and spokes. We also choose rim depth to suit the terrain and riding style, rather than relying on a single test result.
02
The precision of hand building
Rim dimensions, spoke lengths, hub drilling and lacing must work together. Checking the wheel build and spoke tension matters too.
03
Wheels with long-term support
Individually replaceable IDEA carbon spokes, conventional truing and documented bearing dimensions make ongoing wheel care and servicing easier.
FROM TRAINING BACK TO THE WORKSHOP
Experience complements measurement
Team experience connects riding, equipment selection and servicing. The Rafkarna IDEA Cycling Team name reflects the long-term partnership with Rafkarna and its IDEA brand.
Choose your tyre size and rider weight from the IDEA table. For gravel and MTB, the pressure is an indicative value for firm surfaces; adjust the setup to suit off-road conditions.
If you know your tyre’s pressure limit, enter it here. The lower of the rim and tyre limits always applies.

COMPATIBILITY / HOOKLESS
Tubeless tyres in a suitable width
IDEA rims use a hookless profile. Choose a tubeless tyre approved for hookless use and for the rim width, even when fitting a conventional inner tube.

Do not exceed the rim or tyre pressure limit. 1 bar = 14.5 psi.
03 / IDEA TEST LAB
Measure, compare Understand the differences
In a simulation at 50 km/h, R55 CALOBRA had the lowest drag of the three road rims tested. A deeper rim is not automatically the answer for every route — lighter, shallower rims also have their place in the hills and on rolling terrain.
