bent rear fork
A few days ago I noticed the left-hand side of my rear fork was
significantly bent, which probably explains why the rear brake was rubbing almost beyond adjustment, or why replacing the wheel and tightening the quick-release was a bit tricky. It's not really that bad, which is why I rode the bike for days before I realised, but certainly noticeable if you observe. My immediate thought was some ******* had kicked the bike but then I realised it also looks like the tube was badly squeezed one of the very few times I used the D-lock to secure rear triangle and wheel (rather than front triangle & wheel). This can happen for example if the bike drops while locked up against railings and the D-lock breaks its fall. Then again, someone may have helped a bit. Anyway, I am now wondering how bad this is. The frame is steel, so I doubt it will snap without warning, and I've already done quite a bit of riding before I realised. Would a bike shop normally be able to repair this or is it a write-off? The problem is this particular bike is not worth too great an investment really. And while I'm still at it, have you seen this? http://anglegrinderman.co.uk/ -- Michael Klontzas 'If everything seems to be coming your way, you're probably in the wrong lane' (Borstelmann's Rule) |

The problem is this particular bike is not worth too great an investment really. This sort of bend in steel should be pretty easily fixable by any bike shop that can do frame repairs. It's basically a case of bending the frame back into place and checking the alignment. It probably wouldn't cost that much. Alternatively, you could try straightening it yourself.

Alternatively, you could try straightening it yourself. This page on DIY rear end respacing might have some hints. http://www.sheldonbrown.com/frame-spacing.html Thanks for that. I don't think I could do it myself though. It looks a bit more difficult than just straightening a tube. The tube is not bent totally smoothly -- on the inside of the newly produced curve (i.e. the left-hand side of the tube) there is a spot-dent. I'll take it to my bike-shop and see. Judging from previous experience, they'll take it to a frame builder. Thanks. Why not take it to a frame builder yourself. If the tube is 'kinked' I would brace myself for bad news. A frame builder may be able to replace the tube[1] but it will probably be cheaper to replace the frame.
