I'm building up a Giant Cadex CF-R 4 and I want to run it with downtube shifters.I've just realised that my 8 speed Shimano DT shifters backing plates are not compatible with the Cadex frame DT bosses and need a flat backing plate and not the usual type that follows the radius of the frame down tube.

Does anyone know of a source for this different design of backing plate?Pic here of the type I need on a Cadex frame,

Thanks in advance.

Most bike shops will sell them as they are a spare part and often they are what comes with new downtube shifters.
I have had a few that over the years have come with the flat ones where I always need the concave ones.
I will see what I have in the spares box when I get home as I may have a couple, failing that put a wanted ad in the road wanted section and I am sure someone will help.

Hi Mark
I have one only and think it is the right hand one with the indexing. I think.
Will look tomorrow but couldn't see the other one in the usual places.
You are more than welcome to this one.

Hello Jamie,
That's very good of you even if only one it's halfway to what I need and would be most welcome.I will wait until you confirm whether you find the other one or not.I would be happy to send you the concave ones I have in trade,by the way.

Edit: After some further thought I have placed a wanted ad for the backing plates in the road wanted section as you suggested to widen the search if you are unable to find the other one.The bike's all built up and just waiting for the shifters to be in place,which is a little tormenting!lol I'm not sure if the bike shops around my way would have such items,they seem to be the type of shops that just want to flog high end carbon bikes and do as little warranty work as possible.

Cheers,
Mark.
