Topic: SRAM Force RD Rubbing Spokes

Posted on: 8th Mar 2013 12:30 AM    Quote and Reply

Hi all, i just changed to sram force groupset and would like to seek some advice. Currently running ultegra 11-28T cassette with force RD, when I hit 28T, I shift some more unknowingly and the RD/jockey wheel will rub against my spokes. Its hard for me to tell if i'm on the largest cog, so I tend to shift until i hear the rubbing sound and let go of the shifter. I remember I don't have such an issue with shimano shifters and as i recall, i won't be able to shift any further once i reach the largest cog. On 28T, the RD is straight and parallel to my spokes. Any solution to this? Thanks!

1. check the stopper screws.

2. Rear D hanger could be bent. LBS could help to realign rear D hanger.

I had a similar issue with the same cassette and a 6700 RD
Some 10 speed cassettes / hub combinations require a 1mm spacer before the cassette - I forgot to put it on initially after I did and readjusted the RD problem went away - if you don't have the spacer phone round a few LBSthat do mechanic service and ask they will surely have one.

Could be a bent hanger but if it is bent enough to make the RD catch the spokes I am pretty sure you would - be able to see it
- the shifting would be crappy across the range of sprockets

I would check the RD limit screws, such that when u r in the 28T, make sure that the RD would not move further inwards even if u accidentally try to shift down some more.

Hi all, thanks for the advise. I don't have a hanging bar, hard for me to see the movement of the RD as i tune the lower limit screw. Seen some youtube videos, not sure how to tune it such that RD won't move inwards at 28T. Already turn the lower limit screw anti-clockwise and there's some space between the spoke and RD but still some rubbing with spoke. My chain got stuck in between the 28T cog and spokes while toying the limit screw. Think i should go to LBS have it fixed before i broke any spoke...

It honestly sounds like your cassette is too close to the spokes - get a spacer installed to move it away and it will be fine
