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.
Component aerodynamics and deformation under measurable conditions. Choose a test and a specific sample; the results always relate to its dimensions and test conditions.
For IDEA G35 ROUBAIX has no separate rim test result in the source data. The results below are for the labelled CALOBRA sample.

CAD simulation at 50 km/h. The results describe the components tested, rather than a complete wheel. For deformation, a lower value means less deflection under the same load. Wattage figures are indicative comparisons within the test, rather than a promise of power savings for a complete setup.
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.
