I've got a SRAM Red derailleur and I want to sand the graphics off the carbon front pulley plate and clearcoat it. I removed both pulley bolts and the rear plate comes off but the front plate does not. I don't want to destroy my derailleur in the process so I thought I should ask here first.

Thanks!!!!

I think it is with a lot of hassle and patience... as I have seen photos of both plates replaced. Unfortunately I don't know how either (and my "tool-shed" is whatever fits in a travel bag so I don't have the resources that some have). I was just careful with the dremel around the junction area with the body and used tape to protect. Couldn't get super-close (2-3mm) but it was good enough for me in removing the yellow from the Tour Edition.

How about Carbo-Lift. Seems like it could be of use here if you are really intent on an 'as-new' finished product.

Thanks so much for the replies. I'm glad I didn't try to muscle it off as it would have probably broken it.

I guess I'll just try and hand sand it and mask if off real well when I respray. Thanks guys!!!

Garth, with the standard Red derailleur, I think you'll be pretty successful with your only challenging area being the little "silver block" near the "Blackbox" text.

I took mine off with little issue and did exactly what you are wanting to do. However, I can not remember how I did it as it was over a year ago.

Funnily enough, I tried this for the first time last night as I wanted to swop a 2009 SRAM Force inner plate (which is plain carbon) for my Red inner plate (they both weigh 16g btw!). You can remove the inner plate, and although it's fiddly it isn't that difficult. What holds the inner plate to the mech body is a small screw on the mech body, situated close to the hinge that is closest to the inner plate. Take the jockey wheels out first and remove the outer plate. Then make sure you are pressing the inner plate into the mech body with one hand and undo the screw. It only has a few threads on it and you'll need to pull it out. Once the screw is fully removed from the mech body, the inner plate will want to spring off the mech body (which is why you need to hold it). Ease the inner plate off in a controlled way. The inner plate has a rod attached to it that fits into the mech body, and a slot into which you push the spring (which sits in the mech body). When you're putting the inner plate back on, you need to put the spring into the slot on the inner plate, then wind the spring (with inner plate attached) tighter around 180 degrees before pushing the inner plate back into the mech body and re-inserting the screw. As I say, it is a bit fiddly, but it can be done and there isn't anything in there (tiny springs, bearings, screws etc) that can fly out and get lost.

That sounds about right. Getting the screw back in once you move the plate 180 degrees was tricky but not that hard. It can be done and as you can see results in a better looking finish. Now I just need to get my hands on a Tour edition Red RD to do the same work as the all black body is nicer than what I currently have.

No worries. Look forward to seeing the results, as if it looks better than the Force plate, I'll be doing the same thing!

I know how to remove the RED cage, but on 2009 Force there isn't a screw that holds the plate in, but it looks more like a pin (without screw head)
How did you remove that one?
