Scott Addict 20 – Cycling News | Bike Reviews

The Scott Addict 20 is one of those rare bikes that shows it is possible to have a road machine that feels incredibly light and fast – and I mean properly fast – while also offering an endurance style position paired with the highest level of comfort, all without making any real sacrifice anywhere. It’s a brilliant bike throughout, and well specced for the money.

Scott Addict 20: Performance

Twelve months ago, I wrote my review of Scott’s top end road racer, the Addict RC Pro and it was one of the best bikes I rode in 2025. In fact, I’m going to say it probably makes it into my top ten out of the hundreds of bikes I’ve ridden in the last 25 years, so I had high hopes for this less race orientated version.

The Addict line-up is split into two camps. The bikes carrying the RC moniker are the race machines while the standard Addicts come with a more relaxed geometry, all-road capable tyre clearances and more focus on comfort.

The Addict 20 has a relatively tall front end with the bars sitting around 25mm higher from the ground than the equivalent RC, but the top tube is only 4mm longer, so unlike a lot of endurance style bikes the position isn’t that much more compact.

Basically, I could still get into a decent aero position even with the increased stack and compared to something like Ribble’s Allroad models, which are designed with similar intentions, the Scott’s geometry feels much more balanced and natural.

In fact, when I was in the saddle the front end didn’t feel as tall as the numbers would suggest. I still felt like I was on a race bike, but slightly more relaxed and therefore comfortable.

This M/54 sized model has a wheelbase of just over a metre which means it retains the nimbleness of a race bike too. Pointing it down my main, technical, high-speed test descent, I was a little hesitant about how hard to push through the first couple of bends, and while it didn’t feel quite as crisp and sharp as its RC stablemate it felt impressively planted, and smooth through the corner.

A look over the data post ride showed that I was hitting just under 50mph on the descent, which is impressive for a hill that doesn’t have a single piece of straight road in it, and on par with what I’ve achieved on only the highest end race machines.

This bit of road also highlighted the stiffness of the fork as I took the corners at high speed.

Elsewhere, it performed just as well. The chunky down tube, chainstays and bottom bracket area mean that the Addict feels efficient when climbing in and out of the saddle, and the weight of 7.85kg means that it is decent when it comes to hard efforts of acceleration.

The biggest highlight of this Addict though is the comfort. The majority of that comes from the Syncros SP-R101-CF seatpost which also has a cutout to allow you to fit an integrated rear light which is available as an extra.

To fill the gap, you get – as you can see here – a plastic cover. This means that for the length of this section, the seatpost diameter is only half what it is elsewhere. That promotes flexibility and increases comfort.

I found it a little disconcerting at first, but quickly got used to it.

Aside from this, you get 34mm tyres as standard and when I was riding out of the saddle to isolate the seatpost, it was easy to appreciate how good the layup of the carbon fibre is.

The frame and fork have an excellent ride quality, promoting smoothness and increasing feedback. This is a bike that is very talkative to the rider.

Scott Addict 20: Frame and fork

The Addict line-up is available with two types of carbon composite layups. The higher end models get the HMX, which uses a higher modulus carbon fibre, while this Addict 20 uses the HMF version which balances, stiffness, weight and comfort.

It’s definitely a clean looking frame with fully integrated cables, hoses and the seat clamp too. It also has internal frame storage, but access to it isn’t located on the top of the down tube like most bikes, it is actually underneath.

Just up from the bottom bracket, you’ll find a small cover and Scott sells a Save-The-Day Kit designed to fit inside, which carries a tube, tyre lever and mini-pump. Another neat touch is the Torx tool which fits inside the right-hand end of the handlebar. All the bolts for adjustment on the bike use the same size Torx screw for this reason.

Other details include a universal derailleur hanger (UDH), a pressfit bottom bracket and tyre clearance of up to 38mm, which sees the Addict veer into all-road territory.

From a quality point of view, the Addict looks to be exceptionally well made and it’s available in three different paint colours: this Cumulus White, Tungsten Grey and Violet Pink.

In terms of sizing there are seven options, ranging from the XXS/47 to the XXL/61 with top tube lengths of 511mm up to 597mm – that’s effective length as the top tubes slope quite substantially.

This M/54 has a top tube of 551mm, a head tube of 161mm and a seat tube of 485mm centre to centre. With the seat angle of 74 degrees and the head angle of 72.2 degrees the measurements for stack and reach are 578mm and 386mm respectively.

Scott also gives cockpit stack and reach figures which measure slightly differently and include the stem length and handlebar. This makes it easier to compare one of their bikes against a bike that you already have.

Other measurements which may be of interest are a 1,009mm wheelbase, 418mm chainstays and a fork offset of 47mm.

Scott Addict 20: Finishing kit

The Addict 20 comes based around a full Shimano Ultegra Di2 groupset with a 50/34T compact chainset mated to an 11-32T 12-speed cassette, which as you’ve no doubt read before offers stunning shifting performance and a light action at the levers. If you haven’t then you can read our full review here.

The braking is taken care of by 160mm Shimano RT-CL800 rotors front and rear. Not only do they look smart, but paired to the Ultegra calipers you are getting loads of stopping power and great modulation thanks to a lot of feedback and feel at the lever.

Scott has its own finishing brand, Syncros, so it’s no surprise to see the majority of the finishing kit coming from that stable.

The handlebar is carbon fibre with an aero top section, which happens to be very comfortable, while the stem is aluminium and fully integrated in terms of running the brake hoses into the head tube.

Keeping things clean, you also see that there is an aero cover which hides the stem clamp.

The saddle is also from Syncros – its Tofino V2.0 Cut Out. It has a shorty design, and I like the curved shape for long ride comfort.

The WIND 42 DB carbon wheels are from Fulcrum and fit the bill as an all-round set of road wheels designed to provide a mid-aero benefit thanks to their 42mm rim depth while being manufactured to be tough enough for some light off-road excursions.

The rims have an internal width of 23mm (29mm external), so are well suited to blend with that 38mm max tyre width.

We reviewed a set of these wheels back in October so you can read more about them here.

Scott has specced Schwalbe’s ONE tyres for the Addict 20 and that is an excellent choice. Here we have the 34mm width and they feel just as fast, grippy and light as the narrower versions found on many race bikes.

These are one of my go-to tyre sets for fast road riding, and while they might not be the longest lasting due to their soft compound, the grip and suppleness you get more than makes up for the compromise.

Scott Addict 20: Value

The Addict range starts at £2,249 with the Addict 50 and tops out at £6,499 for the Addict Premium, which puts this 20 somewhere in the mid-range at £4,299.

That price compares well to something like Giant’s Defy range – a bike line-up that is very similar to the Addict, offering high performance aligned with comfortable, endurance driven geometry.

The Defy advanced Pro 1 model is £4,199 and comes with a SRAM Rival AXS groupset including a power meter and Giant’s 40mm deep carbon wheelset. It can take a max of 38mm tyres as well.

If you want Ultegra, you’ll need to spend £5,499 on the Advanced Pro 0 model, you do get a power meter with that one too.

I rode the Advanced SL 1 model last year, and it was a very impressive bike indeed.

The Ribble Allroad SL R I mentioned earlier also takes 38mm tyres and for the Ultegra Di2 model costs £4,599. It’s not a bike I’d recommend over the Scott as the Addict is better in every way. It’s here to highlight what good value the Addict 20 is.

Canyon has just released a new CFR model of their Endurace, so it’s probably a given that the rest of the range will be updated soon. For now though, the Endurace CF SLX (the mid-spec frame) model will cost you £4,649 for the Ultegra equipped 8 Di2 model.

That includes an integrated carbon cockpit, their flexible VCLS 2.0 seatpost and DT Swiss ERC 1400 Dicut wheels. You also get a power meter – a 4iiii one in this case.

I rode the previous CFR model when it was launched back in 2023 and found it to be comfortable and efficient, but not as involving a ride as this Addict.

Argon 18’s Krypton model has all-road capabilities, but like the Addict it rides primarily like a fast road bike with endurance-based geometry.

I reviewed the Pro model, but the standard Krypton with an Ultegra Di2 groupset and deep section Scope R4.A wheels will set you back £5,740.

Scott Addict 20: Conclusion

Taking everything into account from a ride and performance point of view, I rate the Addict as one of the best bikes of its genre out there right now. The ride quality is stunning, so is it’s rider involvement and it has the get up and go to satisfy all but the fastest of racers.

Add to all of that the relative value against much of the competition mentioned above and you have the recipe for an excellent bike choice .
