This calibre bossnut is an Evo but I have upgraded it to a 1x11 system this can quickly be made in to a 12 if you know what your doing, IV upgrade the bottom bracket from a power spline to a dub system, wider handle bars from kore, new stem, I have fitted a dropper internal cable routed, front folk is the standard rock shox recon air folk, rear shock has been upgraded again rock shox. Bike has Shimano hydrolic brakes, mineral oil so not quite as powerful as a dot system but alot cleaner to look after and the easiest bleed system IV ever used. both front and back wheels are 27.5 tubeless ready (not converted yet) with a 2.3 on the front and a 2.25 on the rear. The bike itself I have only actually used a handful of time due to health reasons so for its age it's in really good condition. Framed size is a large but with the dropper seat that could easily suit anyone needing a smaller XL. Bike is sold as seen, collect in person
