Soma Riff 27.5" Frame (Pelham Blue) (S)
follow up soma riff frame (27.5). i'm 5'10' 150 pds and ordered size small.
i just built this frame w/ 2x10 xt groupset / manitou markour shock / niner rdo carbon seat post. it is basic, light (24pds) and a blast to ride. the reach is comfortable (not too long) and the wheel size makes bike feel fast but maneuverable.. the rdo niner seat post has 6mm rear shock absorb so takes some rattle off your rear. soma riff = great frame... suggestion - if between sizes order smaller size.
