Though not well known outside of Switzerland, Hans Ulrich Moser's 'Moser Radsport' of Bern was the place to go for a high-end road bike in the 1970s and '80s. The frames were designed by Moser and built in Italy by contract builder Renato Negri (formerly of Pogliaghi), who was also at the time building the highly regarded Freschi and Gianni Motta frames. With wonderful attention to detail and a high-end, subtle finish, these were some of the best custom road frames available in Switzerland at the time.

Probably built in the late 1980s, this great-looking Moser frame was built in Italy by famed contract builder Renato Negri. It is likely to be made from Columbus SL tubing, with internal brake routing, fastback seat stays, and a minimal semi-sloping fork crown—it looks quick even when stood still. The pillar-box red powder coat over a fully chromed frame is in great condition and just adds to the '80s Italian go-fast look.

If you're taking part in L'Eroica or a similar vintage event, this frame is of the correct age, so you won't be disqualified for being a rule breaker!

The frame's been carefully checked by one of our mechanics to confirm the alignment's correct and there's no damage to the threads. If there are any minor issues worth noting we will do so in the overview section below. Please take a good look at the detailed photos so you can see the cosmetic condition of the frame before you buy.

▼HELP SECTION

Seat Tube (ctc) - we measure from the centre of the bottom bracket shell up to the centre line of the top tube to give a consistent measurement regardless of frame design (ctc means centre to centre).

Top Tube (ctc) - this is measured from the centre of the head tube to the centre of the seat tube, along the centre of the top tube.

Chainstay Length - measured from the centre of the bottom bracket shell to the centre point of the rear dropout.

Wheelbase - measured from the centre of the front fork dropout to the centre point of the rear dropout.

Front & Rear Spacing - measured from the inside of one dropout to the other. The dropouts on steel frames can be stretched or squeezed a few mm but it's always best to avoid this if possible, aluminium or carbon frames should never be stretched.

Brake Drop - measured using wheels of the relevant size for the frame, as stated in the technical info section.

Headset Threads - although it's generally recommended to match threaded parts exactly, with headsets you can technically mix and match, unless you have French or the obscure old Raleigh threads, in which case you need to stick to that type.
