- Tubing
- Look for the Columbus label on the seat tube. A 1964 Specialissima wears Columbus tubes, the 1981 Reparto Corse catalog says its handbuilt frames use Columbus, and the 1984 frameset was listed in Columbus SL and SP. The 1973 catalog only says super-light chrome-nickel-moly tubes.
- The frame
- Ask for close photos of the head lugs and seat cluster. Bianchi's racing department built these by hand and says it X-rayed the joints, so the lug work should be tidy. Look for rust at the chrome stay ends and cracks in the paint around the lugs.
- Sizing
- The 1973 catalog listed the Specialissima from 53 to 61 cm, and the 1984 frameset ran 51 to 63 cm. In 1983 the 58 cm frame had a 56.5 cm top tube, so ask for both measurements.
- Threads and standards
- Expect Italian threading, 36 x 24 tpi in a 70 mm shell, as on most Italian bikes. Italian cups are right-hand threaded on both sides, so the drive-side cup can unscrew itself. Ask the seller to read the cup markings before you buy a replacement.
- Wheels
- Bianchi's racing bikes of the period came on 700c tubulars. A five-speed 1970s frame is likely narrower at the back than a modern hub, so measure before you buy wheels.
- Parts it came with
- The 1973 catalog lists a full Campagnolo Record group with Campagnolo brakes. Plenty of these have been upgraded over the years, so check the derailleur and crank against the frame's age.
- Dating it
- The Specialissima name goes back at least to 1964. It was the top road bike in the 1973 catalog and was still sold as a frameset in 1984. The Specialissima X4 of 1987 to 1988 is a later variant, with Columbus SLX, Campagnolo C-Record and an X4 engraved on the brake bridge.
- Paint and decals
- Celeste was the standard color in 1973 and 1984, but not every Specialissima is celeste. A documented 1964 example is green. Original decals sealed under the clear coat, as the 1981 catalog describes, are a good sign the paint is factory.
- Safety jobs
- Old tubulars and hard brake pads need replacing before you ride. Check the stem and seatpost for seizing.
Check the listing photos against these lists, and ask the seller about anything you can’t see. Swapped or missing original parts should come off the price if originality matters to you. For replacements, see our vintage components guide.
