Second-hand Colnago: reference price and what to check before you pay

A Colnago has something few bikes have: you recognise it from a distance. The clover on the head tube, the house paint jobs and a long history in the peloton mean lots of people look for one used, whether to ride at the weekend or to own "the Colnago" they've always wanted. If you've landed here looking for a second-hand Colnago, you'll find very mixed listings and the odd fake. Here's how to tell each family apart, what to check before you pay and a reference price with real data from bicis.net.

The Colnago families you'll see used

The first thing is to know which bike is in front of you, because the name "Colnago" covers everything from an entry-level bike to the one World Tour teams ride.

C series: lugged carbon, made in Italy

This is the historic family: C40, C50, C59, C60, C64 and C68. You recognise them by the lugs, the pieces that join the tubes at the head tube, bottom bracket and stays, as on a classic steel frame but in carbon. They're frames built to last and highly prized by anyone looking for a Colnago "like they used to make". The C60 and C64 come with rim or disc brakes depending on the year; the C68 is already modern, with internal cables and its own seatpost.

V series: monocoque and built for racing

V1-r, V2-r, V3, V3Rs and V4Rs. These are monocoque frames, lighter and stiffer, designed for racing. The V3Rs and V4Rs are the ones you see in the pro peloton and, because of that, the most sought-after second-hand. The most recent ones route the cables through the headset and use a D-shaped seatpost specific to the brand.

CLX, A2-r and Master: the entry point and the classic

The CLX is Colnago's entry-level carbon and the A2-r its aluminium bike: good bikes to start with the brand without paying what a C or a V costs. The Master, in steel, is another story: a classic bike you buy for love, more for restoring or riding at an easy pace than for racing.

Prestige and gravel: G3-X, C68 Gravel and G5-X

The Prestige is the cyclocross bike. In gravel, the G3-X was the brand's first gravel bike, the C68 Gravel is the lugged version and the G5-X is the new race bike, which we tell you about in the Colnago G5-X news. Used ones are still rare, especially the G3-X.

Reference price: what's asked on bicis.net

We don't yet have enough Colnago listings to give a median for the brand alone, so the honest reference is its category. These are asking prices set by sellers, not final prices, with data as of 9 November 2026 (source: Ciclismo en cifras). The low price marks where the cheapest quarter of listings begins, and the high price where the most expensive quarter begins.

How to read it with a Colnago in front of you:

• A CLX, an A2-r or an older rim-brake C usually sit in the middle and lower part of the road table. If you're asked the same as for a V3Rs, ask why.
• A V3Rs, a V4Rs or a C68 sit in the most expensive quarter of the table, and often above it, depending on the build (electronic groupset, carbon wheels, power meter).
• A Master or a classic C40 don't follow the logic of the table: their price depends on condition, original paint and how complete they are.

To fine-tune it for your specific bike, try the bike valuation tool: tell it the brand, year and build and it gives you a range.

What to check before you pay

The carbon and the lugs

Look at the frame in good light and run your hand along the tubes. Look for cracks in the paint, especially where the lugs meet the tubes on the C series, under the down tube (from stones) and on the chainstays, where the chain rubs. A fine crack that repeats in the same area may be just paint or may be carbon: if in doubt, ask a workshop to check it before you close the deal.

The headset and the cables

On the V3Rs, V4Rs and C68 the cables run through the headset. Turn the bars from lock to lock: it should feel smooth, with no notches or play. Ask when the bearings were last changed, because sweat and rain punish them, and changing them on an integrated headset takes more workshop time.

The seatpost, the size and the build

Check that the bike comes with its original seatpost: on models with a D-shaped post, any old post won't do. Colnago uses its own sizes ("48s", "50s", "52s"…), which don't match an S or an M from other brands: look at the model's geometry chart and compare stack and reach with your current bike. Also check the wear on the chain, cassette and chainrings, and that the disc brakes stop without noise.

Invoice, serial number and fakes

Colnago is one of the most copied brands. Be wary of a C or a V priced well below the table, of catalogue photos or of a seller who won't show it in person. Ask for the invoice or proof of purchase and look at the frame's serial number, engraved around the bottom bracket: it has to match the one on the invoice. A bike with papers and a clear serial number sells better and protects you if you want to resell it one day.

Selling yours?

If you have a Colnago gathering dust in the storeroom, list it for free in the bicis.net second-hand section with well-lit photos, the exact model, the size and the build. You'll find more tips in the guide to buying a second-hand road bike, which also helps you know what a buyer will look at.

Frequently asked questions

How much is a second-hand Colnago worth?

It depends on the family and the build. As a reference, used road bikes are listed at a median of €1,100 on bicis.net (45 listings, data as of 9 November 2026); the most recent V and C bikes are usually listed in the most expensive quarter, from €2,900.

How do I know if a Colnago is genuine?

Ask for the invoice, compare the serial number on the bottom bracket with the one on the papers and be wary of a price well below the market or catalogue photos. If in doubt, have a workshop look at it before you pay.

What's the difference between a Colnago C and a V?

The C series is made with lugs that join the tubes, like a classic frame, and the V series is monocoque, lighter and designed for racing. Both are carbon.

What size Colnago do I need?

Colnago uses its own sizes, like "50s" or "52s". Compare the stack and reach on the model's geometry chart with those of your current bike instead of trusting the letter.
