What Can And Cannot Be Repaired On Carbon Wheels?

Whilst clearly we can repair most areas of damage on a carbon frame, can the same be said for carbon wheels? Carbon wheels are certainly a lot more subjective in terms of whether a repair is viable, but we can effect repairs to some areas.

The areas that we generally can’t repair are fracturing to the brake track (on a rim brake wheel), the bead area and spoke hole areas. As rider safety is our first priority, these specific areas are very difficult to test to the limits with non-destructive testing. As such, we do not undertake these repairs.

In terms of fracturing, we can generally repair any other area, as long as it doesn’t go into any of the above areas. We have successfully repaired many types of damage to rim fairings for example.

If you have cosmetic or other damage, we generally treat each case on its own merits. Perhaps email in with your issue first and we can advise from there.

We sometimes get requests where a brake track has warped after heat build-up going down a descent. We can generally help here but we need to ascertain how warped the brake track is and make a judgement from there.

So if you do manage to damage your carbon wheels, before you bin them or just go for a straight replacement, why not get in touch with us first to see if we can help?

The Importance Of A Stripped Frame

If you have ever enquired for a quote or had a repair or restoration work carried out by CBR, you’ll know that we require a completely stripped and clean frame to work on. We can, of course, strip it for you. Yes, even little things such as bottle cage bolts, hangers, cable guides and bearings need to be removed! Whilst perhaps you might think of this as somewhat over the top with some of the modern designs out there (I’m thinking integrated front ends, frames with convoluted cable routing to name but a few examples), there are various logical reasons why this is required.

During the repair and restoration process, your frame is hung in various mounts to allow it to be worked on at different angles. Both the carbon and spray departments have specific jigs and during transitionary phases between and during each departmental stage, we employ storage racks. With the amount of frames we have here at CBR, we have to be extremely thorough and organized to run a coherent operation.

Your frame will be cured at various points during the repair process. We have a specialist curing system that allows a more efficient operation in that they cure quicker than just hanging them to dry for a few days. Curing may also adversely affect the finish on components left on the frame if it wasn’t fully stripped.

Your frame will also be going into a spray booth. When the spray team work, they have to carefully mask the entire frame, which is a time-consuming process. If components are not removed, it makes masking more difficult and there is a greater chance of overspray.

We hope this article has provided more insight into our processes and why we require a stripped frame. If you are unable to strip the frame fully yourself, we also have a fully equipped workshop here at CBR with Cytech-qualified expert mechanics. Alternatively, you could use your trusted local bike shop. If you are going to part-strip the frame yourself and let us do the rest, as some customers do, please note that we require the wheels if you would like us to set your gears and brakes up.

HOW TO SPOT A FAKE F10 PINARELLO

We recently came into the possession of a fake F10, so we thought we would share the differences with you. Please note that this is only one of many replicas flooding the market.

What’s so bad about a fake carbon bike then?

Carbon Bike construction is almost impossible to unpick. When layers of are sandwiched with inferior material to make it cheaper, you can see it until it breaks. We’ve seen mostly dangerous examples so I would question any seller of a high end bike where there is no paperwork.

Luckily it is pretty easy to spot the poor graphics against a real one.

Can you spot the fake? Look at the photos below.

CAN A MANUFACTURER REPAIR A BIKE?

Consider this – If you damaged your car door, and you have to repair it, who is best skilled to do the job?

The manufacturer uses machinery, materials and automation processes to construct an entire component, however the repairer is skilled to remove damage and restore utilising totally different tools and skills for the job.

In carbon it is much the same, bikes are manufactured using a variety of machinery to mould semi-complete components which require assembly as well as inspect for manufacture anomalies. The repairer is equiped to identify fracture anomalies, largely not experienced by the manufacturer. The repairer utilises a variety of diagnostics and localised repair processes, again, uncommon to the manufacturer.

The two skill sets are unrelated and should not be confused with each other.

CARBON BIKE REPAIR SALVAGE

Apart from the environmental aspect of needless waste, you can see just from a short period how many carbon bikes, some exceptionally expensive, are written-off through myth or demand.

Looking at this pile in our stores, it would be conceivable to assume that at least 70% of these frames and forks could be out giving someone great cycling pleasure. We have a salvage buying programme if anyone would like to have one of these bikes repaired for a fraction of the cost of a replacement. They all come with limited lifetime warranties so call with your size and your preference and we can look for you.

NON-WARRANTY SOLUTION FOR CARBON BIKES

Despite the lifetime warranties provided by many manufacturers, it is still the case that if your claim is out-of-warranty then you still need to replace at your cost.

Why not explore the repair route? If it is repairable, we provide limited lifetime warranties on the repair work and 1-year paint warranty for a lot less than a replacement frame in your specific colour. CBR brand is well represented and integrated throughout the cycling industry. We save our customers millions of pounds per year collectively. If you would like more information please drop us a line, phone or visit Carbon Bike Repair and we would be happy to review your inquiry.

RESULTS OF POOR CARBON REPAIR

We recently received this bike with a top fracture. It did not take long to discover that a previous repair had taken place.

We recognise the repairer’s work in this case. What’s the fuss? Remember how I always bang on about symmetry and repairs which meet the specifications of the surrounding material, well when we find that the repair is thicker then the surrounding material this occurs.

Why? Because the frame is designed to specifically respond to the flexing and movements subjected to it. When you stop this from happening then this occurs. You notice the original carbon has cracked on the edge of the repair.
