0zzy Posted December 15, 2008 Report Share Posted December 15, 2008 i set up my back wheel straight, set up my brake and go out to ride, after a few hours my back wheel has moved. i have set up my back wheel numerous times now and it just keeps on happening does any body have any tips on keeping them in place? its a monty 221 pr frame, viz hub and monty knotched cams if that makes any difference. i really need to sort this problem out as soon as possible as i want to ride lots over the christmas holidays!! thanks in advance ozzy.x Quote Link to comment Share on other sites More sharing options...
Muel Posted December 15, 2008 Report Share Posted December 15, 2008 File the notches deeper and do the hub bolts hub tighter. Quote Link to comment Share on other sites More sharing options...
grant_hundley Posted December 15, 2008 Report Share Posted December 15, 2008 Tried tightening the bolts more? Deeper notches would help... Quote Link to comment Share on other sites More sharing options...
0zzy Posted December 15, 2008 Author Report Share Posted December 15, 2008 bolts are as tight as i can possibly do them......so i dont think its that. ill have a think about fileing the knotches bigger id like some more ideas first though..cheers.

Increases the possible tightening torque massively Quote Link to comment Share on other sites More sharing options...
shamus Posted December 15, 2008 Report Share Posted December 15, 2008 Strip any paint off the dropout area where the wheel is being clamped.If your frame is painted, as the wheel moves around it will be rubbing off little bits of paint etc, these will then act a 'bearings' between the snail and the dropout, meaning the wheel can slip a little easierWorked for my BMX and meant i never needed to run any tensioners.another possibility is to take the file to the actual dropout.Rough up the area which is normally clamped on, also make sure you rub the cam up a little as well on its inside face.Hope some of this helps bud Quote Link to comment Share on other sites More sharing options...
Jitters Posted December 15, 2008 Report Share Posted December 15, 2008 Strip any paint off the dropout area where the wheel is being clamped.notching the snails a bit more and greasing the bolt threads seems to be sensible too.That sounds like a good plan to me. Gonna give that a try on my zm2 as I have the same issues, although adjustments aren't as frequent as the OP mentioned. Quote Link to comment Share on other sites More sharing options...
weirdoku Posted December 15, 2008 Report Share Posted December 15, 2008 You shouldn't need to notch the cams more. Are you winding the cam up with your hands until it won't go any further? If yes, get a spanner/pliers and hold onto the cam ends, wind it up one more notch. You shouldn't be able to move this at all with your hands afterwards, your chain should also be nice and tight.I had a similar problem, winding the cam with my hands, they kept slipping. But after winding it up one more notch with pliers/spanner, mine has not slipped once. That was 1 month ago. Quote Link to comment Share on other sites More sharing options...
cai Posted December 15, 2008 Report Share Posted December 15, 2008 get a spanner/pliers and hold onto the cam ends, wind it up onehe's snapped two axles doing this before. shows how strong Viz is Quote Link to comment Share on other sites More sharing options...
weirdoku Posted December 15, 2008 Report Share Posted December 15, 2008 he's snapped two axles doing this before. shows how strong Viz is Snapped an axle? Sounds impossible! They must be really poop!My cams (16mm holes) goes on my hubs, not on my axle so I guess I don't have to worry about my axles.But seriously, cams really don't move/harder to move out of place if they are done up tight.

Captain Scarlet Posted December 16, 2008 Report Share Posted December 16, 2008 (edited) A longer allen key (or spanner).I guess whilst everyone is on the topic of making it tighter, having an allen that is like double the length of one that comes in a normal allen key set obviously gives you greater leverage, but there is a significant difference in amount of tightening torque you get from it.

Ashley-Wood Posted December 16, 2008 Report Share Posted December 16, 2008 spanner on end of allen key = extra leverage works a treat lol, or your drop outs may be indented? so try some spacers there to stop the bolts moving back into the indent.

eskimo Posted December 17, 2008 Report Share Posted December 17, 2008 It just came to mind that snail cams should have knurling on the outside of them. It wouldn't end up costing no more than the current retail price if they didn't CNC them. Quote Link to comment Share on other sites More sharing options...
