Re:
The RM Element is 20" centre to top, 18" centre BB to top of top tube/seat tube weld. SID air shock too. Something has been spilled on top tube and taken the paint/laquer off in one place which is a shame. Can get pics later if you're really interested.
Easton Ultralite, V or disc, although one V stud is missing for some reason.
Think bearing in mind the shock is a better one than I remembered...needs to be £80 plus the postage...
