Rockman Kortz 2, should be £660 retail on Tarty. Doesn't come with a rear hub or a rim, so that's more than the 90 quid difference between that and the Koxx. I don't see Rockman having the same background, level of riders and testing involved; no offence Bigman and Ben Savage, but you aren't Vincent, Gilles, Benito, Diaz etc. and I don't see countless world cup podiums being won on a Rockman either. I think Koxx are expensive premium products, but I also think they can justify it.
