Description
A super-wide 37mm max outer and 25mm internal tubeless clincher rim has an optimal aerodynamic performance zone when using 28–32mm tyres, lowering rolling resistance and improving comfort and control—especially on imperfect road surfaces.
At just 780g (carbon spoke SL version), the Helikon 107 is exceptionally light for its depth, offering rapid acceleration and agile handling on flat, technical, or undulating courses. Advanced carbon fibre materials and modern moulding techniques ensure high lateral stiffness, low inertia, and uncompromised speed when every second matters.
IMPORTANT SERVICE INFORMATION!
Helikon C107 models are 20x carbon fibre / alloy bonded spokes and can be trued only via access through the rim bed spoke holes using an internal tool and not by the external nipples.
Helikon 107 models are 24x Steel CX Ray spokes and can be trued in the traditional way using an external nipple spoke key tool.
MAXIMUM RECOMMENDED TYRE PRESSURE (Do not exceed!)
25mm – 90psi / 6.2bar
28mm – 85psi / 5.8bar
30mm – 80psi / 5.5bar
32mm – 75psi / 5.2bar
