robnewland Posted April 8, 2006 Report Share Posted April 8, 2006 (edited) Recently on my onza t-raptor the chain came off without me realising it, and got stuck between my bashguard and chainring - scratching the paint quite badly and bending the front chainring. So I took it off and sorted it out. Five minutes later it came off again and bent the chainring once more. So I decided enough was enough and went out to replace the bent chainring.£16 down and with a new middleburn chainring fitted I don't have this problem anymore because the new one is wider than the cheapo one that came with my onza, and subsequently the chain can't slip down into the gap between my chain and bashguard.This was quite an annoying problem, but I was wondering has anyone else ever suffered this?

watto Posted April 8, 2006 Report Share Posted April 8, 2006 is it on these cranks ? If it is then yes i had the same problem and replaced it with a race face ring which was only £13, had no problems since this. Quote Link to comment Share on other sites More sharing options...
robnewland Posted April 8, 2006 Author Report Share Posted April 8, 2006 Yep its the armstrong cranks. I may get some new cranks later on though as I have seen some nice ones about.I am happier now that I have replaced the chainring as I know it shouldn't happen again.

Tony Harrison Posted April 8, 2006 Report Share Posted April 8, 2006 You did the right thing buying a Middleburn one - always worth having decent transmission. I remember most Sundays I used to fix my mates bike before we went out for the day, and there would always be something totally wrecked, which was wierd as he could usually still ride the bike well... Anyway, once he had a chainring that only had two bolts in it, next to each other. Needless to say the chainring was egg-shaped when we took it off...

watto Posted April 8, 2006 Report Share Posted April 8, 2006 So basically its a warning to anyone thinking of buying these cranks when on a tight budget make sure you buy a better chain ring straight away . It will benefit you in the long run. Quote Link to comment Share on other sites More sharing options...
Wiggins15 Posted April 9, 2006 Report Share Posted April 9, 2006 armstrongs have to be one of the most annoying cranksets ever. I used to have them and my chain always came off and i bent a couple of chainrings. I found though that bigger chains or thicker chainrings solve the problem.
