I recently bought this on eBay, and fixed it up. I'm apparently at least the third owner. The first owner used this on triathlons, resulting a bunch of energy drink stains all over the top and bottom tube. I think throughout the ownership transfers, parts were removed. Annoyingly, I'm not even sure of whether it is an r1000 or a r900. Ironically, without the model badge, it is impossible to distinguish. Anyways, a lot of parts are from a r900. Shimano 105 all over, with sun mavic rims on...
