After some info from those in the know,been looking into tuning my rear Ultegra road mech,found some carbon cages from Fibre-Lyte,they do an ultra lightweight cage weighing in at 2gr but how safe are these for everyday riding?
Fibre-Lyte have been making them for years and make chainrings from the same stuff. Don't they have 2 flavours though? Light and ultra light. I'd do your sums though and see how much you are saving and spending versus buying a dura ace mech. There is also a seller on ebay who does both mech plates.
I have,i asked if he did Ultegra stuff,he didnt mention about interchangable bits,dont want to order if they dont fit properly,better get the dremel out i suppose
Have ordered the outer from Fibre-Lyte now,wouldve liked an inner but hey ho
