Just building up one of the SPcycle M-05 frames at the moment too, size M. Painted turquoise it weighed 1,000gr on the nose stripped of all small parts. Finishing is actually rather good so I would be disappointed if it did crack in front of the rear brake mount, I guess we'll have to see. Building up with Elite Wheels 30mm IW, Thunder Burt/Racing Ralph 2.35s, Elita One post, WCS riser bar, Uno stem, Romin Pro, Fovno Ghost granks, XT 12 spd cassette & chain, SLX mech and shifter, Rockshox SID Select SL, Deore brakeset, XTR SPDs. Looks ace, should be quick and around 9kg / £1250 outlay. Will post some photos when finished.
