Topsy Posted June 4, 2011 Report Share Posted June 4, 2011 When I tension my chain properly I try to get it that it can move about a bit but obviously not jump. That means you can move it around about 3mm in both directions without too much force. Guess that should be alright? So, when I have it set up like that and start pedaling I get a nasty clacking sound, like the chain is slipping off the last bit of the freewheel. It also does it when there's no weight on the rear wheel. Chain is a new KMC K710. Problem started with a half link after about 2 months. freewheel is a Trialtech Sport 108 (I think) The noise doesn't really build up confidence so I wouldn't mind knowing what's causing it and how to solve it!.. Thx [haha, first time using spellcheck as I don't trust my spelling today and it wants to change "Thx" to "THC"] Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 4, 2011 Report Share Posted June 4, 2011 What frame/tensioner/rear sprocket (assuming front freewheel?) setup are you using? Could be chain wrap, possibly... Quote Link to comment Share on other sites More sharing options...
Topsy Posted June 4, 2011 Author Report Share Posted June 4, 2011 What frame/tensioner/rear sprocket (assuming front freewheel?) setup are you using? Could be chain wrap, possibly... Frame: Inspired Fourplay Pro 2010 Tensioner: Trialtech Race Rear Freewheel, sprocket etc. is all still that that was on the bike when it came.. So if it isn't a trialtech Sport 108, correct me Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 4, 2011 Report Share Posted June 4, 2011 If you put up a photo of your tensioner setup that should help out a lot Quote Link to comment Share on other sites More sharing options...
Topsy Posted June 4, 2011 Author Report Share Posted June 4, 2011 Could have actually though of doing that >.< Here we go: And like this it's silent: If you need some differen't angles just tell me Quote Link to comment Share on other sites More sharing options...
Mikee Posted June 5, 2011 Report Share Posted June 5, 2011 When it is tensioned properly and you pedal it backwards lightly by hand, does it feel free with no tight/stiff areas? Because I find that you usually get slightly tighter and looser parts in the drivetrain as things aren't always perfectly centric and fixed tensioners don't compinsate for this. I used to get funny noises sometimes when I used a fixed tensioner and it was over tensioned on a tight spot so it could be your problem aswell. It could also be chainwrap as Mark said. You could try using an old mech as a double wheel tensioner to see if that solves the problem aswell. Quote Link to comment Share on other sites More sharing options...
forteh Posted June 5, 2011 Report Share Posted June 5, 2011 The clacking would normally indicate bad chainline, the side plates catching on the tips of the teeth as they ride over the sprocket. Can you not tension the chain upwards? That will eliminate any issues with chain wrap, although I run a similar amount of wrap with no problems.

Topsy Posted June 5, 2011 Author Report Share Posted June 5, 2011 (edited) I do get some spots where the chain starts wobbling strangely, and if it's tensioned a little more I get spots where I hardly can pedal at all any more.. Actually I can't see any edges that could be catching.. Can't tension it upwards yet, need the chain to get a little longer.. I might add a vid showing the problem, though it might also only be my stupidity... :$ Edit: stupid me.. Was right with the stupidity.. The chain tries to jump out of the tensioner which seems to be bent inwards. :$ Will try and solve it and if I still get strange noises I'll post here again! By the way, are there instructions for a spoke tensioner somewhere? Edited June 5, 2011 by Hopping_Topsy Quote Link to comment Share on other sites More sharing options...
