Thought the 16mm bore cylinders were for single caliper set ups and 19mm for twin. i may possibly be wrong.
The only thing that i really noticed on changing over to radials was the fantastic feel and smoothness of operation.
Oh yeah and I had no beer tokens for the rest of the month.:puzzled:

Now that was most helpful! Many thanks Desmo748.

I am a little confused as to this brick banding stuff your talking about?

That plastic stuff that goes round big heavy boxes, about 20mm wide and as long as you want it to be.

I suppose you could use wet n dry but the plastic banding wraps round the piston really easy.
