Sadly there is a catch. Frame has a crack at the top tube/seat tube junction and as such is sold as a wall hanger or repair job. Cracked it on my first ride. I was using a 350mm long ControlTech seatpost as you can see in the pictures and it was in the minimum amount but im guessing for this frame you need a 400mm long seatpost so that its quite a distance down past that tube junction. For a couple of years now ive planned on getting it sorted but never got round to it. Ive been in touch with Enigma and they'll fix it no problem. Drill a couple of holes at either end of the crack to prevent it going any further and then weld a bead over the top. Jobs a good un and youve got a King Kahuna for £300. Below is my build thread and link to some pictures of the frame as it is now which will be uploaded fairly soon
