That should be 55 x 56 c-c, not 55 x 57.

Time to thin out the herd and I am offering this to the list before it goes elsewhere.
55 x 57 Jan de Reus 531C frame and fork with Shimano 105 headset and BB. Note these are the mid-80s 105 components and not the later stuff. Spaced 128mm. Has Campag ends on rear and fork. Racing number tang on top tube with internal rear brake cable routing. Pantographed sloping crown fork, braze on FD mount, under BB cable routing. BB shell is also panto'd Reus. Paint is in pretty good condition with some chipping in places. PO had his birthday punched into the BB for ID purposes. The clear portion of the decals are yellowed with age. Takes a 27.2mm seatpost. This frame was imported directly from a shop in The Netherlands.
Photos of the frame at the following link. Please bear in mind these are older photos and there is some chipping that does not appear. I have not had time to take current frame photos. If you want updated shots then I will provide, but it may be a day or so.

This is a really nice riding frame that is just a tad bit too big for me else it would stay in the stable. I always felt like I was flying when I rode it.
Special price to list members only of $220 shipped in the continental US. Cashier's check or USPS money order preferred. Personal check if I feel I know you well enough. Sorry no Paypal. I will throw in some nice usable Shimano 600 crank arms to sweeten the deal.
