RC30 Mk2 If of interest can sort some more detailed images to show condition + vital 1'shim + Pace (NOS) 1" treadless steerer:I also could offer some Mark 2 RC30s - I am original owner of these - as you will see in nickel plating is a bit scruffy minor corrosion, but only cosmetic.
Carefully cleaned up for my last retro field, which was , Roberts DB - so currently set to 11/8th” threadless - but can also supply a 1” uncut Pace steerer tube plus the magic Pace converter shim.
£260 posted inc. both steerers + shim
