Hello all, sad news to report. A crack has developed in the top tube on my much-loved Canyon Ultimate AL 9.0. The frameset is nearly 5 years old, but that seems young at my age It's done about 1600km/year so that's probably about 7000km - mainly rough London streets on the commute, but also a bit of light touring, the DunRun, winter bike etc.
I noticed last night there was a slight bump in the top edge of the rear brake cable port, where there hadn't been before. I looked through a magnifying glass, and the crack is already 8mm long.
1. What to do? I have no claim under guarantee, as I bought the frameset second hand, and I've used a rack etc, so the question is: ride it and see? Or attempt a repair? It looks too hard to weld - and likely to cause stress problems if it were to be welded.
2. What to replace it with? I've loved its efficiency and directness. Sharp steering and a rock solid bottom bracket area. A new Canyon frame is nearly £800, post Brexit! Ideas welcome.
