Bobby Fox Posted June 1, 2009 Report Share Posted June 1, 2009 Just a quick one, im new to mod and have been riding a stock with vertial drop-outs for god knows how long. Ive got my bike built up with snails fitted, ive also marked where the snails meet the frames snail cam bolts so i can see if there has been any movement. A ride or so later and the chain although not completly slack is a bit looser than i used to have on my stock and you can see a very slight curve in the chain from a side on view. The snail cams or wheel hasnt moved at all, just wondering if running snails tends to give slightly less chain tension and is this normal for a mods chain to be like this? It rides fine by the way.sorry if this is a lame question just needed a quick answer to put my mind at rest cheers for the help guys nice one.

JT! Posted June 1, 2009 Report Share Posted June 1, 2009 Are you running the cams with teeth? Or are they smooth? Quote Link to comment Share on other sites More sharing options...
Bobby Fox Posted June 1, 2009 Author Report Share Posted June 1, 2009 They are smooth. But they 100% havent moved as i marked them with tip-x thinking it could be a new chain needed, ive had that one for a few months and might be stretching?

JT! Posted June 1, 2009 Report Share Posted June 1, 2009 I'd move to cams with teeth, mine was doing the same thing, i switched, problem solved.New chains tend to stretch more, older ones shouldn't. Watch out if you're running a front freewheel as depending on what angle the cranks at it can alter the chain tension. Quote Link to comment Share on other sites More sharing options...
joshlyd1 Posted June 1, 2009 Report Share Posted June 1, 2009 You might be better off with the snail cams with teeth Just a thought Josh Quote Link to comment Share on other sites More sharing options...

Cookyboy Posted June 1, 2009 Report Share Posted June 1, 2009 A lot of front freewheels are not 100% evenly round if you get what i mean, so if you pedal the cranks around and keep an eye on chain tension you may see it slightly tighten or loosen depending on the position of the cranks.

JT! Posted June 1, 2009 Report Share Posted June 1, 2009 Push on your chain like you would do to check it's tension, then spins the cranks backwards with your other hand, you'll probably notice the chain get tighter and slacker. Quote Link to comment Share on other sites More sharing options...
MikeCottTrials Posted June 1, 2009 Report Share Posted June 1, 2009 chain tugs are much better imo Quote Link to comment Share on other sites More sharing options...
A.Baxter Posted June 1, 2009 Report Share Posted June 1, 2009 I prefer chain tugs, they are much easier to use etc... Adam Quote Link to comment Share on other sites More sharing options...
sstein Posted June 1, 2009 Report Share Posted June 1, 2009 Tugs for the win. Quote Link to comment Share on other sites More sharing options...
JT! Posted June 2, 2009 Report Share Posted June 2, 2009 I hated my tugs, always had to over tighten them and they would usually slip into a normal tension. And that was with profile bolts. Cams with teeth are by far the best thing i've used. Quote Link to comment Share on other sites More sharing options...

Bobby Fox Posted June 3, 2009 Author Report Share Posted June 3, 2009 Got my new chain and trial-tech cams today! Fitted them making sure the chain was tight at the point when the cranks and freewheel were at there slackest point. Its worked good tension all the way round the pedal stroke and the same after a couple rides! cheers for the help guys Quote Link to comment Share on other sites More sharing options...
