A classic horizontal tube break...the norm. Diagnosis: structural repair without problems and restoration of the color of the Pinarello bike tube.

The black Pinarello bike has a crack in the down tube. The crack was caused by an accident involving the top tube near the bottom bracket. Diagnosis: easily repairable under warranty, even beyond the three-year period.

Following a fall, the gear hanger on this Scott Addict bike was bent beyond repair. This might seem like a frame to be thrown away, as the hanger, being designed as a fixed part by the manufacturer, cannot be removed or replaced. However, Doktorbike repaired it by rebuilding the derailleur hanger on a lathe and milling machine and securing it to the frame with a stainless steel screw and epoxy resin, making the part replaceable in the unfortunate event of a subsequent breakage.

This is a very common type of damage, and the only possible repair is to re-wrap the broken part with high-strength carbon fibre.

The repair is secure and visually appealing. In the photos, you can see the broken dropout and the repaired dropout. The frame still needs to be painted to restore its original appearance.

The first photo shows the condition of the wheel when it arrived here: one spoke had been replaced previously, rather crudely, and obviously the wheel still had problems.

However, we were able to repair it by completely replacing the spoke and the flange.

The finished work can be seen in the last two photos: the spokes have been re-laced and the wheel is now "as good as new".

This case is very similar to the previous one: the first photo shows the condition of the wheel when it arrived at the workshop. Obviously, a spoke glued in this way cannot work properly and the wheel is affected, so it had to be completely replaced.

Once the work was completed, the difference was very clear, as can be seen from the last photos.

The wheel is now usable again.

This fork is a rigid, handcrafted lefty, definitely not manufactured by the parent company.

A probable error in judgement on the part of the craftsman who built it meant that the lower plate area was significantly undersized in relation to the stress to which the fork is subjected. In fact, on the first ride, a crack appeared: the plate immediately began to detach from the fork body.

The only feasible solution, given the impossibility of removing the plates, was to wrap the part with new carbon fibre from the outside, in order to make it safe and usable again.

As can be seen from the last three photos, once the work was completed, there was no longer any trace of the problem.

It is good practice to check the condition of the fork steerer tube from time to time.

Tightening the handlebar stem, designed for steerer tubes made of other materials, can have devastating effects on carbon; unfortunately, this is a widespread problem that occurs in all bike models.

The risk is that the steerer tube will break while the bike is in use, obviously putting the cyclist's safety at risk.

The first two photos show the condition of the steerer tube that was brought to us, while the last photo shows the steerer tube after the work has been completed.

An Ergal pin is also inserted inside, which guarantees the future safety of the steerer tube.

One spoke of this Corima wheel was damaged in two places: about one-third of the way along its length (starting from the rim) and where it attached to the rim itself, as can be seen in the first photo.

In this case, it was not necessary to replace the entire spoke; only the end of the spoke needed to be replaced.

The finished work can be seen in the second and fourth photos.

Carbon protectors are now available for the most popular MTB frame models: Trek, Cannondale and Specialised. The entire range is not yet available, but you can contact us for more information.

In addition, it was already possible to have custom carbon protectors for your frame when it came to us for repair; this is still feasible for less popular models.

The protectors are shaped to fit the lines of the frames perfectly and, of course, have holes for cable routing.

They are very easy to install, as all you need is some double-sided tape.
