Not sure what difference this may make but just adding to the general knowledge I notice the Beta fiber plates are now noted as being Ferodo rather than Adige. I personally haven't seen any but I do see Beta wants a lot more money per plate.

 

I noticed some of the bikes that use the 3mm Barnet plates also call out 1 plate with a different number. I ordered one just to see if it’s the same form factor with a different thickness. I’ll let you all know what I find.

Interesting the plate is still 3mm thick but the friction material is semi-metallic and the plate width is thinner. Something I didn’t notice about the kevlar plates is they are slightly wider than the stock plates.🤔
