Finished the 3 month Centurion Prestige build. Adjusted everything on the stand. Test rode up and down the block, brifters and brakes, it's working nicely so I go to end of the block, turn left uphill and stand on the pedals. I didn't finish the second rotation when it came apart violently.
This was a tough lesson; when building on an old frame with unknown history, build and test before any cosmetic work.
Only 10 minutes to live
So, the worst has happened; n-1, and this will be rectified soon!
