Second-hand Specialized Tarmac: price and what to check

If you're looking for a second-hand Specialized Tarmac, here's what you need so you don't overpay: which generation each one is, what changes between ranges and what to check before you hand over the money. The Tarmac is Specialized's race bike and one of the most common carbon bikes in group rides across Spain. That's why there are lots for sale, and very different from each other.

The key is this: two Tarmacs with the same name can be worth twice as much as each other. The generation, the brakes, the frame level and the groupset explain almost all of the difference.

What people ask for a used road bike

There aren't yet enough listings of a single model on bicis.net to give the Tarmac its own figure. What we do have is the range for road bikes, counted from active listings. A well-built carbon Tarmac usually sits in the upper half. An older one with rim brakes and a mid-range mechanical groupset, near the median or below.

The Tarmac generations

Before you look at the price, place the bike. The year is on the invoice and, if there isn't one, a Specialized shop can tell you from the frame's serial number.

Tarmac SL6: the last with rim brakes

It arrived in 2017 and was sold with rim brakes and with discs. It's a light, very balanced bike. Today the rim-brake ones lose value faster, because almost the whole market wants discs: that's where the most affordable Tarmacs turn up. If rim brakes work for you, it can be a good buy.

Tarmac SL7: discs and more aero

It came out in 2020 with disc brakes only and internal cables. Specialized presented it as an all-rounder, fast on the flat and uphill, and stopped making the Venge, its aero bike. It's the most sought-after generation second-hand: it holds its price well if it's been looked after.

Tarmac SL8: the most recent

It arrived in 2023. Used ones are few and usually ask at the top of the range, especially with an electronic groupset and carbon wheels.

The ranges: S-Works, Pro, Expert, Comp and Sport

Within each generation, the frame and the build change with the range:

• S-Works: the lightest carbon and the best components. It's the most expensive new and the one that loses the most euros over the years, although it's still pricey.
• Pro and Expert: high-end carbon frame with a mechanical or electronic groupset. They're usually the best balance between what you pay and what you get.
• Comp and Sport: a slightly heavier carbon and a mid-range groupset. The easiest to find and the cheapest.

Look at the groupset too. An electronic one (Shimano Di2 or SRAM AXS) pushes the price up, but needs a battery in good condition and, with SRAM, knowing how old it is. A power meter or carbon wheels justify part of the price, but not what they cost new.

What to check before you pay

The frame

Look for cracks or knocks on the chainstay, next to the bottom bracket, on the seatpost and on the head tube. Marks on the seatpost and the stem clamp tell you whether they've been overtightened. If in doubt, ask to see it at a shop or for a service with an invoice.

The internal cabling

On the SL7 and SL8, the cables and hoses run inside the headset. Check that the steering turns smoothly, with no play or noises. Changing the bearings is more expensive and slower than on a bike with external cables.

Drivetrain and brakes

Check the wear on the chain, chainrings and cassette, and that the rotors aren't bent or very thin. On rim-brake bikes, check the wheels' braking surface.

Size and paperwork

Try the size before you pay: a Tarmac in your size is worth more to you than a cheaper one that doesn't fit. Ask for the invoice and check that the serial number matches. Before you buy, ask a Specialized shop whether that frame has any pending service or recall from the brand.

Buy or sell your Tarmac on bicis.net

If you're looking for one, check the second-hand road bikes and filter by your province. You have a general guide to buying a second-hand road bike and the brand's price guide: how much a used Specialized is worth.

If you're selling yours, put the generation (SL6, SL7 or SL8), the range, the groupset, the size and the year in the listing, with clear photos of the frame. To price it in a minute, try the bike valuer.

Frequently asked questions

How much is a second-hand Specialized Tarmac worth?

It depends on the generation, the range and the groupset. As a reference, on bicis.net a used road bike asks a median of €1,100, and one in four asks more than €2,800 (41 listings, data as of 31 October 2026). A carbon disc Tarmac usually sits in the upper half.

Which used Tarmac should I buy: SL6, SL7 or SL8?

If you want the cheapest and rim brakes work for you, an SL6. If you want discs and a current bike, the SL7 is the easiest to find. The SL8 is the newest and the most expensive second-hand.

How do I know the year of a used Tarmac?

From the invoice and, if there isn't one, from the frame's serial number: a Specialized shop can look it up. Be wary if the serial number has been removed or doesn't match the paperwork.

Is a used S-Works worth it?

It can be, if it's been looked after and it's your size: it loses a lot in euros compared with new. Check the frame carefully and ask for the invoice: it's the range bike thieves are most interested in.
