Buffwhack Posted June 8, 2008 Posted June 8, 2008 9 speed ultergra - I feel that the jockeys are too close to the spokes when I am on the biggest sproket. Do I set this distance with the H/L adjuster screws or could it be another problem? I know I use the L screw if it is not selecting the smallest sproket but turning the H does not seem to do anything. Advice please. Thanks Buffwhack2008-06-08 07:30:34
turtlek Posted June 8, 2008 Posted June 8, 2008 check that your derailer hanger is not bent and if it is take it to the lbs or buy a new hanger
Canaris Posted June 8, 2008 Posted June 8, 2008 triple check that the hanger is not bent, then use the L-H settings
Johan Bornman Posted June 8, 2008 Posted June 8, 2008 This has nothing to do with any setting. Don't fiddle with screws to fix this problem. Also don't start bending things, lets just figure out what is wrong first. However, before we declare this to be a problem, what do you mean by "feel that the jockey(s) are too close"? There is only one jockey, which is a nickname for the entire derailer. What are the symptoms?
Tumbleweed Posted June 8, 2008 Posted June 8, 2008 johan, if the derailleur was parallel to the spokes, would you reckon it was a bent hanger? holy roller2008-06-08 23:25:28
dirtrider Posted June 8, 2008 Posted June 8, 2008 I think it has been said before . Either the hanger is bend or the bottom cage is bend . Turning any screws will just frustrate you more . You can always remove a few spokes as I think that will solve a few issues .
AndreZA Posted June 8, 2008 Posted June 8, 2008 johan' date=' if the derailleur was parallel to the spokes, would you reckon it was a bent hanger? [/quote'] can be a bent cage aswell. They bend easier then the hanger.
MintSauce Posted June 8, 2008 Posted June 8, 2008 Bornmam overcomplicating things again. By 'jockeys' he OBVIOUSLY refers to the two jockey wheels. And fiddling with the screws is the first thing I would try since it's not exactly going to break the rear derailleur off and since the screw is there specifically to keep the derailleur away from the spokes. It's the first thing you check....DUH!
mbaymike Posted June 8, 2008 Posted June 8, 2008 take it to the lbs and don't mess with it if you are not sure

It's the first thing you check....DUH! I realise you don't particularly like me. However, think about your answer for a minute. The OP didn't articulate the problem well and now everyone jumps onto the bandwagon offering solutions. That is called male answer syndrome, or MAS. A condition where men feel they have to come up with an answer to a question. The fact that they don't know what the problem or real answer is, is always irrelevant in MAS answers. On The Hub, MAS answers are usually punctuated with "My 2 cents worth.," This is a clear indication that the poster is MASsing away. Back to the problem. If the top limit screw is the problem as you suggest, the symptoms would have been an overshift and chain in the spokes. I think we still have to find out why he considers the jockey (or as you suggest, the two idler pulleys) to be too close to the spokes. Johan Bornman2008-06-09 00:21:07
dirtrider Posted June 9, 2008 Posted June 9, 2008 I got to agree with you on this one Johan . The screw will for sure take the derailure further away from your spokes but it will also mean you loose some gears ! Not very wise .
Johan Bornman Posted June 9, 2008 Posted June 9, 2008 johan' date=' if the derailleur was parallel to the spokes, would you reckon it was a bent hanger? [/quote'] It depends on the groupset brand. On Shimano, the derailer hangs almost perfectly in the vertical plane. On Campag, the derailer is slightly angled towards the spokes and may appear parallel (or almost) to the spokes but out of plane with the vertical. I haven't examined SRAM derailers and don't know what their natural "hang" is. Unless the hanger is badly bent, it is almost impossible to gauge if the hanger is slightly bent. This can only be checked with hanger tool. Hangers should be perfectly in plane with the frame - fore-aft and up-down. Wheels with too few spokes and spec'd with Campag may occasionally ping the spokes if you honk hard uphill. This is from wheel flex and the spokes scraping the inside surface of the hanger. It is only a momentary ping on the downstroke from the left leg. It isn't dangerous as no-one I know is strong enough to make the wheel flex that extra 2mm so that the spokes actually jam in the jockey.

scotty Posted June 9, 2008 Posted June 9, 2008 I have a similiar thing with my 9spd Tiagra derailer, if its in the big ring at the back it rubs slightly on the spokes.
