Just ordered a set of Rebas through ALLtricks so many thanks to timb34 for spotting the white ones and posting the link.
The description of the lockout states on the tee which turns out is actually a crown mounted version, so managed to get them in black, 15mm axel, tapered steerer, 120mm travel and crown mounted lockout.
Exactly what I was after and all for £250 posted taking the exchange rate into account through Paypal. States 2 day delivery timescale on their site!
One happy bunny.
