EXACTLY what i want to know Wes!!

I thought the RS Turbo had the largest master cylinder fitted as standard, 25.4mm ? Anyone know if thats right?

I've got a 23.xmm fitted at the mo so really want to get the biggest one i can fitted..... if im right in thinking that the RST one is the biggest, then thats the one to have!

Im sure Christian knows a bit about this and the price of the correct one??
