Considering the amount of machining that#s gone into the backplate of THIS, AND the fact that it's anodised, £50 for one of these is a bit of a bargain.
If you were to manufacture these yourself in the UK you'd probably pay £50 per backplate just for the machining, sod the rest of the processing that goes into it.
Stick a big plate on a mill. Get it fastened down & then stick some holes in it for each part (patterned onto the large plate). Bolt down through those holes to secure each part once you've milled it out. Then set it running & leave it for a while. Come back & hey presto; a load of parts ready for anodising....
You can cut alu very quickly.
The moulds for the plastic bits might cost a lot at low volumes, but once the volume comes up a bit, then they are cheap bits per part. And one multi-cavity mould will probably do all the bits you need for one chain device.
And Yep - I think that chain devices are well over-priced! A bit like those K-Edge anti-chainsuck devices and their alternative Garmin mount. I try to stay clear of these types of products.
My other half bought me some KCNC fancy jockey wheels at Christmas after I said it was the kind of 'bling' part that I'd like to treat myself too, but never would as they aren't really a necessary purchase.
