Gulf colour one here, as above not quick up hill or on the flats but point it down and it flys, handles great through the twisty stuff corners on open flat corners and is just generally a great hard tail frame. As a serial frame changer I’ve gotta say this ones been with me for a year and I’ve no intentions of selling it on.
Build wise Xl frame shimano zee/xt, dt wiss wheels/maxxis tyres, bos deville forks and fox doss dropper post comes in about 30.5lb.
Size wise med/lrg gotta friend who’s 5.9 and on a medium but recons he could of gone for a lrg with short stem combo.
Don’t do the bottom bracket I’ve found it to be crap re greasing it about once a month.
Now your only issue is if you can decide if you want it before the last medium is sold in the uk.
