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.

Look carbon dropout repair

LOOK 586 DROPOUT MODIFICATION

If you ever need an example of the level of competence within CBR here it is. A newly redesigned and injection moulded dropout to replace the original Look design.

Why did we change it? The left picture shows the original carbon dropout which is poor frankly. You can’t, without considerable risk, re-align the hanger without snapping the carbon dropout because there is NO support from the skewer when the wheel is fitted. There is too much reliance on the strength of this carbon section when, in fact, it needs to be less exposed.

This repair was for a Swiss client who loves the bike but after trying to repair it we gave up and suggested that we re-design the dropout to a different hanger system which he can replace as per normal if the hanger is damaged.

I don’t criticize the rest of the bike or the company but in our opinion this design, like some other manufacturers, have fallen short in this department. I would like to hear from Look as to why this is so. It is possible we have missed something obvious. I would be happy to share that update with you all in due course.

 

REPAIR & RESTORE SAMPLE

De-Rosa King XLight damage to the top tube. Customer wanted a full restore to what it was before the damage. Top tube fracture repaired. Restoration includes silver metallic lettering in the correct font and a red colour match.

‘Hello CBR

It looks perfect. I cannot see where was repaired!
I am really happy!’

SEAT STAY

Got this Cube Litening that had a side impact. The seat stay was broken off at the top and bottom of the chain stay. The seat stay piece was also snapped into two pieces. The first job was to align the broken parts together with a strong epoxy on the frame itself. Once cured in perfect alignment the repair could begin. Each break was rebuilt with 5 layups of different CF weave to ensure stiffness. In this case I resprayed the repair.
