Hi,

I've just bought a damaged rear Red derailleur to tune and replace the Force one on my bike to save approx. 50g. It needs new front and rear plates and pulleys.

I'm going to get an inner plate from fibre-lyte and probably the pulleys from ebay, but can't find an outer plate. SRAM sell all of these together as one replacement part but it isn't going to be cheap to buy, especially when I only need one bit of it. Does anyone know of any after market outer plates as I can't find any at all.

If need be I can probably tidy the existing one up as it isn't too bad, but I was hoping to save another couple of grams by going aftermarket.

Thanks
Phil

Just a thought, as I don't have access to the SRAM pricing for such things, but could you get a Force cage from them, as I'm guessing that the reason for the Red one to be so expensive is due to the ceramic pulleys?

Why doesn't fibre-Lyte make one of these?

The outer plates never seem to be straight forward fit with Sram rd's. I don't think we've ever tried to completely strip an Sram Red or Force rd, but I think Boonen has and from what I remember it was quite intricate to put back together again. I could be wrong about that but a search on the forum would confirm the details. We have done some Shimano XTR outer plates (medium cage M972) but even they aren't totally straight forward.

Having stripped the derailleur it wasn't that bad anyway but it would nice to have a new one in a new 3k weave

I'll try and get hold of a second hand Red rd and see what can be done.

By the way gumgardner, just had a look at that Ruegamer of yours. Sweet ride, love the picture with the deep rims and tan sidewalls. 8)

,,,,,and had a look at the Crumpton. It just keeps getting better and better :D

I haven't got round to reassembling the derailleur. If its just the outer plate you would need I could post you mine if you send it back after.

I didn't realise you were just up the road (ok, an hour). You should call down for a coffee one day :D

Regarding the outer plate, it would be better seeing the full derailleur so that we know how the outer plate fixes to the main body.

I remember asking Stephen about an outer plate when I bought my inner plate. I have got the dremel out on my outer plate, its got holes everywhere, so how much of a weight gain could you expect if Stephen could make an outer plate, be interested to see if it will be worth it. Has anyone weighed the outer plate cage ?Question for Stephen, if you could make an outer plate ,could you put some holes in it like a lot of the tuned outer plates.

I'll weigh my outer plate whilst it's dis-assembled. I'm not so much after weight loss, I could do with a new one as mine is damaged.

If we did make an outer plate, the yes, we could 'tune' them exactly as the customer wanted. Bear in mind though that the outer plate is a very supportive piece and so introducing anything that could weaken it may affect shifting performance.

Thanks for the reply Stephen, If you do make one and you need a red mech to try it out on, I would be happy to test it. Im london based.

Any news on a Sram outer cage replacement?
Does someone know if it's possible to remove the outer cage on a first generation sram force RD? It doesn't has a phillips screw that holds the cage in place, but some kind of 'pin'…

SRAM have a spare parts catalouge, the reason the outer plate will be so expensive is becasue it comes in a kit with both pulleys, inner and outer plates. i dont see why it couldnt be built, im pretty confident i could build the spindle that the outer plate is attached to if someone could make a plate that would fit it. P.S. when i did my SRAM red rear D tune i knocked off 2 grams just by removing the clearcoat off the bit. :D
I guess there's worse hobbies than making a bike light? Right?
