I bought a used carbon frame to use on the trainer. A Neil Pryde that I got for next to nothing.
The previous owner dropped the chain so it scuffed up the drive-side bottom bracket area (no structural damage) but he couldn’t tell since he couldn’t get the bottom bracket out. And I think this was the reason for him selling it so cheap – looks like he tried to use a screwdriver to remove the BB?
Luckily, I have the right tools and was able to pop the BB right out. Visual and tap test inspections show no structural damage. I will be getting some unidirectional carbon fiber tape and repair this area (for fun).
So, here are the first things I do to a used frame to prep it for a build.
- Inspect prior to purchase to see if it is worth buying.
If yes, then after you get back home,
- Remove fork and inspect for damage.
- Look at headset bearings to see if need replacing.
- Do a rear dropout/rear derailleur alignment. This frame was actually perfect!
- Remove BB and inspect inside frame.
- Thoroughly inspect entire frame for any structural damage.
- Clean and wax frame with Lemon Pledge.
Now, it’s ready for assembly.
