New Bike Nightmare, ARGHHH!!!

stoobydale

This is what happened on the second time out on my new bike. Doesn't look like any sort of structural damage, just paint and primer, I hope. At the end of the season I think that I will fill it with some car body filler and prime and paint it. Has anyone else had a problem like this? It happened when my chain came off moving from inner to outer ring.

Take it to a bike shop ASAP and get them to adjust the gears properly! Then get down to halfords and put a bit of car touch up paint on it sooner rather than later

You need to fit a Dog Fang to prevent your chain dropping down inside the ring.

BTW, the photo might be a bit deceptive but there does not seem to be much clearence between the chainring and the stay. Are you sure you have the correct bb fitted?

Smokin Joe: The dog fang looks like a good idea but unfortunately because of the design around the BB I don't think that I could fit one. The camera is closing up the depth of field, but that was my initial thought when I noticed the damage.

Robbie the roadie: Yeh I think a touch up pen from Halfords is the best bet. The gears are set up right it's just one of those things. I've had this happen at some time or another on every bike I have although not with such dramatic effects. I do a little bit of airbrush/spray work so it wont be a problem to fill it and paint. I also have a plotter so after I've touched it up I think that I will cut a piece of vinyl to protect the area in case of future mishaps.

I'm still gutted about it though. :x :twisted:

Heck, if you think that's bad, I'll post a piccie of my nice steel Audaxer - when it comes back from the shop's gear fettling service!
I bought a Halfrauds touch-up kit - works reasonably well - I found the paint stays soft for a week or two, but the lacquer final coat's well worth the trouble.

Changed over from a Campag. Veloce chain to a KMC last week - Marked reduction in chainsuck (which is the cause of mine), but not sure if that's just down to the old chain being old, and the new chain being new.

I've fitted one to mine despite the seattube flaring out near the BB just where it needed to fit - solved with a bit of modding to the dogfang. Wasn't going to ride it without, having done something very similar to what you did very shortly after getting my previous new bike (if it's any reassurance that is carbon and now 10 years old and still going strong).

You got off lightly. A similar problem on my Van Nicholas Vardar last year tore a big chunk out of the carbon chainstay effectively rendering the frame worthless scrap.....less than a month after buying it. Fortunately it was a £200 ebay bargain frame, so I didn't get too angry :evil:

Having said that, I patched it over with brushed on epoxy and have been riding the bike ever since. The damage is only to the top carbon layer, so I don't think it's likely to snap anytime soon.

It's the reason that I would never buy an expensive carbon frame though - they are far too easy to damage compared to metal.

[the dog fang idea is a nice one, but how many current carbon frames have a round downtube? - very few]
