I just got my brand spankin new ibis mojo hd frame on friday and i'm rapidly gaining a big pile of boxes of bits to build it up, i've got a pair of bos devilles and a vipr rear shock coming some time next week and provided the bos one is the correct spec (bos are insisting that the vipr should have a 57mm stroke length which i know is wrong it should be 51mm) i will have a 2013 200mm eye to eye 51mm stroke fox ctd shock for sale, any ideas what its worth? its got an rrp of 380, is 250 about right?
