hello all, i would like to ask help to identify this frameset, it should be from British builders, the story is telling that it could be Chas Roberts frame and painted in red. cause this frameset has many strange things, i will try to post it here
Lets start: serial number is the same on fork(steerer) and frame (bb shell). No 900737, according Roberts system it should be 1990 year, 07 month, and number 37 is the frame made that month.
Frame has Cinelli microfusione lugs, cinelli microfusione bottom bracket shell and SCA fork crown (drilled for brake originaly, not for fixie ride), fork crown is described as lightweight for only 150grams, and is internal into fork blades. both front and rear
dropouts are Campagnolo. tubing is unknown, but for seatpost sizing 27.2mm it should be Columbus. frameset weight is astonishing light, frame weight 1.76kg, and fork weight 0.64kg. frame tubing inside bb shell looks like not butted, so my guesing its Columbus Record or KL tubing. BB shell is british threaded
very interesting and unseen Seat tube lug/ cluster, looks like seatback style, but has brazings to join seatstays. sizing is 56x56cm, and final thing, it has braze on's for bottle cage ???. the filler on those braze on's looks the same as on lugs, so guess is that bottle cage braze on's were made buy this frame builder
maybe someone has ideas what it could be, or i should really think its Roberts and start to search for decals
