After seeing that it was possible to repair carbon rims and replace one or more spokes on Lightweight wheels, some customers began to ask us if we could solve the braking problems that often occurred on these wheels.
Specifically, they felt jolts and jerks when braking, a sign that something was wrong with the braking track.
Doktorbike began measuring the thickness of the rims at the braking surface, around their entire circumference, and found that there was a significant difference in thickness, as much as 0.7 mm between the minimum and maximum thicknesses.
This irregularity was obviously the cause of the problems reported by customers.
The next step was to develop a solution:
Doktorbike built the mould shown in the photo, which is made specifically for lightweight wheels. To fix the irregularities on the braking surface, carbon fibre (the same as the rim) is applied and high TG (high temperature resistance) epoxy resin is used, which is necessary for the braking surfaces given the high temperatures reached during braking.
The results so far have been excellent.
