D Rock 45 Posted April 10, 2011 Report Share Posted April 10, 2011 (edited) having problems with getting my chain tension right its lose on one spot and rely tight in an other, recently had tarty bikes fix my chain problem an had it worked better then it did before. they said i need a new chain an to stop the lose spot tight spot change my crank arms from onza to some other crank arms were the freewheel screws strait on the the arm to reduce the tight an lose spot. i was also told the same by selectbikes to change them as i bought the new parts of them. ive bought echo crank arms and a new chain, an it hasn't made a difference. so having spent the money an it hasn't made a difference is getting on my nerves could there be any other reason why i have this annoying problem, if any one could shed a little light on the subject it would be a big help. thanks in advance dieter edit : could it be the freewheel am using. its a tensile 96 click Edited April 10, 2011 by D Rock 45 Quote Link to comment Share on other sites More sharing options...
ForrestDump Posted April 10, 2011 Report Share Posted April 10, 2011 A friend of mine has the same problem and also has the same freewheel that you are using. I fiddled about with his setup to try and find the problem, at first I thought it was the cranks (Onza cranks) causing the problem so I tried them on my bike with my freewheel, an Echo SL; although the tight and loose spots were still there they were not as bad as they had been on his bike before. The reason for the tight and loose spots is down to something being out of centre (I think) which results in a cam like effect, so if it’s not your cranks causing the problem then it may be the freewheel (I think). Hope this will provide an answer to your problem. Quote Link to comment Share on other sites More sharing options...
Azarathal Posted April 10, 2011 Report Share Posted April 10, 2011 You'll always get a tight and loose spot. Find the slackest point and tension it there, its what I did before I had my wheel slammed in the dropouts with a spoke tensioner. Quote Link to comment Share on other sites More sharing options...

Hope this will provide an answer to your problem. it has helped. i took my chain off an spun the crank arms round slowly. you an see the whole of the freewheel move up when the right peddle is facing forward an dips down when spun round with the right peddle then facing to back. You'll always get a tight and loose spot. Find the slackest point and tension it there, its what I did before I had my wheel slammed in the dropouts with a spoke tensioner. i work from the loose spot. but when i get the right tension in the loose spot the i tight spot is way to tight causing a clunking sound as the chain is to tight on the hub Quote Link to comment Share on other sites More sharing options...

If the chain is too tight then it can wear out the bearings quicker (I think). Quote Link to comment Share on other sites More sharing options...

If the chain is too tight then it can wear out the bearings quicker (I think). same happens hear, i think its safe to say its the freewheel, the bash ring stays central an no up an down movement when cranks arms spun edit: is there any freewheels that are good quality for under 60 pound edit: looking at the V!Z Seventy two on tartys are they any good, my mates got one an says its great, but thats one persons opinion. has anyone got one an have problems with it Edited April 11, 2011 by D Rock 45 Quote Link to comment Share on other sites More sharing options...
super Posted April 11, 2011 Report Share Posted April 11, 2011 Go for an Echo SL. prob the best freewheel available. PS. I've got some chain tension/brake mount alaignment issues on my echo control and so my chains running really slack at the moment but it doesn't cause me any problems. I wouldn't worry too much about the slack you'll get from having a slightly eccentric freewheel, just set it up on the tightest spot and it'll be fine.

ForrestDump Posted April 11, 2011 Report Share Posted April 11, 2011 (edited) Go for an Echo SL. prob the best freewheel available. I would defiantly agree with this as this is the freewheel that I'm currently using and I haven’t had any problems at all with it at all. I've used the Echo, the Rockman 108 and a Tensile 60 click and although the Echo is the most expensive out of the three I'd defiantly say it's well worth it.
