I also felt as though I should have been going faster for the amount of effort I was putting in (admittedly based on nothing more than old-school RPE with heart rate as a rough guide) – but in the end was surprised to post my fastest time on that particular route, which I ride regularly – since last summer. I was a bit preoccupied with the uncomfortable saddle on my first ride on the Addict RC 15. Using something as crucial as a seatpost clamp to save weight isn't a great idea in practical terms, but it worked fine – in fact better than some wedge designs that can easily get, erm, wedged – and we didn't experience any seatpost slippage. It uses a grub screw on a band at the front of the seatpost and feels flimsy, using a 3mm Allen key to tighten. The unusual seatpost clamp arrangement is aimed at cutting weight, adding a claimed 12g and Scott says it's a carbon-friendly design too. It was hard and unforgiving so that unless saddle height was perfect to the fraction of the millimetre it was uncomfortable. The Syncros Belcarra saddle would be the second upgrade. Call me old school, but a 56cm bike with a stubby 100mm stem, like the Specialized Tarmac SL7 Expert (opens in new tab), just doesn't look right. The 120mm stem and 42mm bar are sensible choices for this size. The finishing kit is also Syncros branded: the proprietary bar and stem are separate aluminium components (compared with the pro-level RC Ultimate's one-piece carbon bar/stem) but they work with the frame’s clever internal cable routing (which is also mechanic-friendly, according to Scott, with channels built-in) to give a very neat front-end integration with not a cable in sight. The Addict has clearance for 28mm tyres and perhaps Scott has specced them just because it can. These are good all-rounder tyres but for us would be the first upgrade: this bike deserves faster, lighter rubber, as we found. They have a modern, wide internal rim width at 21mm and they’re tubeless ready but Scott supplies them with tubes and Schwalbe ONE Race-Guard 28mm clinchers. These are pretty decent carbon wheels, with a retail price of over £1,000 if bought separately and weighing just over 1,500g. The Addict RC 15 gets Capital 1.0 35 Disc wheels from Scott’s in-house brand Syncros. Perhaps the only part of it that deviates from the usual disc road bike set-up is the 160mm rotors both front and rear. Since Shimano Ultegra Di2 is specced on all four bikes we tested back to back there’s no need to go into the pros and cons – suffice to say there aren’t many cons it’s a superbly functioning groupset.

Our test bike did come with a full stack of spacers under the stem, making the front end a little tall and the super integrated front end makes it a little tricky to fettle: it’s no longer a case of simply swapping the spacers under or over the stem: although the spacers are split, so that you can remove them without disconnecting the hydraulic hoses and Di2 wires that run through the middle of them and down into the head tube, the cover-cum-top cap has to sit directly on top of the stem, meaning the steerer has to be cut if it’s to be used – and it definitely wrecks the clean look if it’s not used. Overall it has a beautifully clean aesthetic.Īlthough the size 56 is designated ‘large’ (didn’t 56 always use to be medium?) the geometry is fairly standard, with head and seat angles at a classic 73° and the stack and reach as you’d expect for a race bike of this size: a ratio of 1.43, which is neither too upright nor crazy aggressive. To underline the Addict's aero ambitions there are some really smart little aero tricks like the magnetic cover on the caliper mounting bolts on the left fork leg.
