My brother in law is in need of a new seat for a big ride we are doing in Africa in May. I wanted to build him a carbon seat so I designed a prototype that I have not seen on the market yet. Not only is it light but its super flexible for carbon. […]
Another victim to remind us that car doors opening into the road can be a real hazard to any cyclist. This 2012 Wilier XP suffered a frame fracture and shifter damage. A fairly simple repair in 4 x 300 Uni layup. Nice and thin but strong. You can see the tape covering the decal to […]
A common problem with carbon is over-tightening. Here I am rebuilding a deep crack. Its important to ensure all layers are exposed to build a strong repair. This Fi’z’ik seat got the MTB treatment and cracked in 3 stress areas. Again you can see how brutal I get in clearing damaged areas for structural repairs […]
Scott Genius MC20 Carbon frame with alloy rear stay mounting: Broken rear stay mount. Normally this is a throw away frame because the cracked alloy part is too close to the carbon frame. Epoxy and heat don’t mix. I welded the alloy mount at the same time protecting the carbon frame. In fact I increased […]
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 […]
Another sad but all too typical worn brake tracks on perfectly good wheels. It’s a time consuming job to ensure the re-build is flush, level and can withstand high heat and abrasion. Don’t ask what I use…it’s not off-the-shelf epoxy.
I was sent a set of Bontrager 700’s that had melted down an Alpine run. The rear wheel profile was deformed from the incorrect pads and brake surface was de-laminated. Luckily the wheel was still true so I took on the project. Firstly the profile had to be reset by creating a mold of the […]
