Wonder Woman Posted May 21, 2009 Posted May 21, 2009 Di CPD...when you just pick up the bike spin your back wheel do your pedals start moving?? It sounds to me like you may need a new free-wheel body, that will also make your gears jump and it makes a screeching type sound when you free wheel??

[/quote'] When I spin the back wheel the pedals dont move - the freewheel action is still there. I have replaced the outer bit that the cassette goes on (cant remember the name of that thingy ma jobby). I dont have that plastic bit between the spokes and the cassette. My gears do jump a bit. So, would replacing the freewheel body fix this? I am irritated with my mtb at the moment!!

jpdub Posted May 21, 2009 Posted May 21, 2009 Hi Di Hope you well. how the bontis doing? hope the are they are getting used at least,

Okay, then that is the part that I replaced. It has a brand spanking new one! So, then that cant be the prob?? Now I am really confused!

Wonder Woman Posted May 21, 2009 Posted May 21, 2009 Hmmm, sounds to me like you might need to take it in for a full service...Something is definitely not right.So you fixed the free-wheel and you still getting an awful sound?? Makes no sense to me... You sure they put it on correctly??
BrendonMyb Posted May 21, 2009 Posted May 21, 2009 Hi Di This might sound stupid, but its happened to me before. Is your backwheel tight enough on the quick releases & in what condition are they. I fthey are worn from wheels being taken on & off constantly for the bike rack n stuff, eventually the skewer part that attaches onto the frame start to move on the farme. This is very little movement but as ive noticed, un-aligns the wheel itself causing i sideways play movemement as you peddle & stop peddleing. In other words the wheel is wobbling within the confines of the frame spaces that the skewers fit in. This will most definately cause skipping gears & when freewheeling might cause the chain to slacken up as there is no torque being put down on the peddles anymore. Like i said, this has happened to me & the quickest solution & only solution was to replace skewers in my case ( the problem was that they didnt have those grooves in the end caps of the skewers anymore & even tho i tightened them properly it would still slide when under peddle torque). Just uncanny that the symptoms sound similiar. Please just check though before you go out & just buy new skewers. I could be totally off track here & as they say, use it - dont use itBumpNgrind2009-05-21 02:05:19

I say this as the problem takes a while to show. Like, on Sunday at the bike park I rode a 40min route to the park, rode for an hour and only after I started jumping a bit I got issues. This is a second hand built up bike and a lot of the parts are older. Now you have me wondering.... Seems to make sense! On Sat I went to the park as my first ride on the wheel, had some issues then at the park Riaan tightened the wheel and I had only 1 or 2 issues after. Okay, so I will test that. Perhaps see if I can borrow skewers from a friend and test on Sunday. Just thinking out loud here... the prob first started 30km into my Magoebas ride and is not constant. It takes a while to show its head. I had budgeted to do my full service on the course with Johan at the end of June or to do it through the lab before I head on my multiday. Sucks being at the office all day - I want to go check my bike and see if this is the problemo. Thanks guys.
droo Posted May 21, 2009 Posted May 21, 2009 I've seen what bumpngrind describes - the ridges on the retaining nut that clamps against the dropout can also wear away, causing movement between the axle and dropout. I've not seen it cause gears to jump or jam, but it could be the issue if, as you say, this only happens in the smaller sprockets.
Canaris Posted May 21, 2009 Posted May 21, 2009 consider the chain. A worn chain can jump. Sometimes a line can be bent or hurt.consider the derailer hanger alignment. THe hanger does get bent in tansit.Worn gears? maybe.Chain to long? maybe
