Scott Addict RC 2020 first-ride overview: Now aero’ized

Scott Addict RC 2020 first-ride review: Now aero’ized

It was once 2007 when Scott first printed its 790g ultra-light Addict platform. With it, Scott set a brand new benchmark for gentle and stiff racing frames, and quite a lot of competition spent years attempting (with some good fortune) to overcome it. Since then, the Addict RC, Scott’s resolution to a light-weight all-around race device, has been ridden to numerous WorldTour wins, together with a Grand Excursion, with quite a lot of generational overhauls alongside the way in which. Right through, the Addict has remained a lot the similar platform as that unique trend-setting body – a minimum of in the way it was once outlined.

For 2020, Scott has overhauled its race-focussed Addict RC lineup as soon as once more – this time including some glaring aero design parts to the already gentle, and now stiffer, platform. And sadly for Wilier’s new 0 SLR, which claimed to be the arena’s solely entirely included light-weight disc race motorbike, neatly, that gross sales pitch lasted all of 24 hours. That’s proper, the now disc-only Addict RC gives a fully-integrated cockpit and cabling, too – and it’s arguably smarter in execution.


Suave integration for all

Tale Highlights

  • What: Scott’s GC-contending light-weight racer, up to date.
  • Key updates: Disc-only, included cockpit and hidden cables, aero tube profiles, revised body development, designed for 28c tyres.
  • Weight: 850g 54cm body, 360g fork, 295g handlebar/stem. Entire motorcycles from 6.9kg.
  • Value: To be introduced September 1st.
  • Highs: Amazingly responsive, however nonetheless comfy for all-day racing. Suave integration and a focus to element.
  • Lows: Now not sufficient check time to make a decision.

Within the 77-slide presentation for this new motorbike, over 45 had been devoted to Scott’s new included handlebar/stem and comparable cable routing. From lowered aerodynamic drag, to claimed device weight financial savings – a lot of it’s credited to the motorbike’s new one-piece bar and stem.

All seven fashions of the brand new Addict RC see both the mechanical or digital shift cables/wires, at the side of the disc brake hoses, run throughout the bars and instantly throughout the head tube. That is slightly distinctive as many included techniques are restricted on house and limit use to digital transferring solely (comparable to Wilier’s that was once printed the previous day). To triumph over that, Scott were given a little bit ingenious.

This patented introduction makes use of outsized 1.5in headset bearings on the height and backside, with the end bearing offset 3mm rearward with regards to the ground. The fork steerer is then offset too, and tapers from its 1.5in diameter on the backside to a nonetheless huge 1 1/4in (very similar to Large’s OD2) on the height. By way of combining the 3mm offset and the slimmer steerer operating thru an outsized bearing, Scott has created room for cables and hoses to run in entrance of the fork steerer sooner than weaving their approach to the related corners of the motorbike.

It’s one thing Scott has dubbed “Eccentric bicycle fork shaft”, and it targets to provide complete cable integration with out impacting transferring, handlebar resistance or body stiffness. Actually, Scott claims that the brand new Addict RC’s head tube is stiffer than it was once sooner than.

Scott hired its in-house part corporate, Syncros, to provide the included handlebar and stem setups – those function on all fashions. The costlier Addict RC fashions will obtain the one-piece carbon fibre Combo Creston iC SL bar. The Addict 10 and underneath get an alloy two-piece included setup (Creston iC 1.Five handlebar and RR iC stem), with identical ergonomics and aero profiling, together with the hidden bolts.

That Combo Creston iC SL bar is relatively the bit of apparatus, with a V-shape that makes use of continuing carbon fibre from the stem throughout the bar. Moreover, the form permits for clean cable paths from the bar and throughout the stem. In comparison to Syncros’ earlier one-piece bar and stem combo, the brand new Combo Creston iC SL is claimed to be 26% stiffer and 27% extra compliant. It’s mentioned to weigh an outstanding 295g and naturally, comprises an out-front laptop mount.

The form was once advanced with ergonomic analysis from spouse motorbike becoming corporate GebioMized. Accounting for hand sizes and force mapping, the bar gives a 2-degree flare on the drops and an oval form that’s designed to scale back force issues when at the tops. Moreover, the emblems of the bar are designed to assist in grip will have to you select to forgoe bartape at the tops.

In any case, the steerer clamp and headset topcap are coated by means of a magnetic duvet. After all, being a one-piece device makes long run servicing a little bit trickier, however fortunately, the headset spacers, will have to you wish to have them, are cut up and will also be modified with no need to undo the hydraulic brakes.

The inexpensive two-piece model will have to be more practical to provider, however keeps the similar headset device because the one-piece carbon model.

The cheaper price two-piece model is way more simply serviced, and the stem will also be swapped with no need to disconnect any cables or hoses. The transferring cables and brake hoses are routed over the stem and coated by means of a magnetic duvet. It’s a identical design to what Large did with its Propel Disc, albeit reputedly even more straightforward to provider and cleaner-looking. Scott has no longer supplied a weight determine for its two-piece device, however at a wager, it’ll be a minimum of 150g greater than the one-piece model.

Aero tube profiles and lowered waste

Scott claims the brand new Addict RC saves six watts (at 45kph) when in comparison to the former Addict RC. And whilst a lot of this is most probably all the way down to the brand new included bar and stem, the tube shapes were overhauled, too.

The down tube, head tube, seat tube, seat put up and seat remains all now function aerofoil shaping, identical to the ones used on Scott’s Foil and Plasma. And despite that reshaping, the brand new Addict RC body is claimed to be 14.5% stiffer.

Scott has constructed proper to the brink of to be had actual property in this block.

A part of this is consideration to the carbon layup, however maximum of it’s reputedly all the way down to widening the tubes. As an example, the 1.5in bearings within the head tube supply a much wider floor space for each the end tube and down tube to connect with. The fork steerer diameter is bigger than sooner than, and most probably achieves a lot of the similar stiffness advantages that Large claims of its efficiency avenue motorcycles. The entire width of the PF86 backside bracket is now hired for the down tube and the chainstays that drift from it.

As is changing into a not unusual vogue since BMC did it in 2017, the brand new Addict RC has decreased seat remains, with Scott suggesting it’s extra aero. Alternatively, aerodynamics is a handy bonus for the dropped remains, with the design additionally growing extra body compliance.

Scott claims the brand new Addict RC suits the Foil Disc in body compliance. Making convenience comparisons to a devoted aero race platform doesn’t learn neatly on paper, but it surely’s extra comfy than the former Addict RC, and the Foil Disc is arguably extra comfy than the rim brake Foil that Matthew Hayman rode to win the 2016 Paris-Roubaix. Reputedly, it’s simply comfy sufficient for a race motorbike. Upload in that it’s designed for 28c rubber (extra in this underneath), and there’s surely extra cush to this race motorbike than sooner than.

The aero tube profiles, greater body stiffness and included cable routing do, on the other hand, lead to a weight penalty. And consistent with the Addict’s legacy, Scott has long past to spectacular lengths to stay the burden aggressive.

Along with a cultured carbon layup, the brand new Addict RC reportedly employs a brand new production methodology that halves the collection of items required to make a body – slicing down on wasted subject matter overlap. A key component of that is the hole moulded rear finish, the place the chainstays, seat remains and dropouts are moulded as a unmarried piece. Scott then use a suave aluminium thru-axle insert to verify no clamping power is put at the hole carbon construction. It’s a design that Scott has already used with nice good fortune in its Scale RC and Spark RC go nation mountain motorcycles.

The dropouts at the moment are moulded as a part of the seat and chain remains. Notice how they’re hole.

The similar manner is used for the fork which additionally includes a one-piece development that comes with the dropouts.

The usage of an exterior seatclamp aids in weight loss, too. The place maximum motorcycles of this stage have moved to a type of included seat wedge, Scott’s exterior clamp weighs simply 12g, and is claimed to provide extra even clamping rigidity, which allowed the matching seatpost (142g claimed) to be lightened, too. By way of comparability, that seatpost is similar form as what the Foil makes use of, however is 66g lighter.

Scott claims to have stored any other 19 grams by means of overcoming the desire for the everyday flat mount adapter and 2nd set of bolts for the entrance brake. As a substitute, the brake caliper is fastened immediately to the fork floor, with the bolts coming in from the entrance of the fork. The fork is sized to suit a 160mm rotor. That is then given a magnetic duvet to offer a clear floor to the wind and onlookers.

All advised, the brand new Addict RC HMX body (54cm) weighs a claimed 850g as opposed to the former model which was once 810g. Fork weight is 15g heavier than the former model’s 345g. Alternatively, the brand new included handlebar is claimed to drop just about 100g from the former included model, and in a similar fashion, the seatpost is 60g lighter. And so total, Scott claims, the brand new Addict RC is lighter than the former Addict RC Disc.

All fashions of the Addict RC use the similar HMX body and fork, excluding the top-tier Addict RC Final (as examined). This motorbike options an “HMX SL” body and fork, which sees an additional 60g dropped.

Geometry optimised for 28c

For those who’re nonetheless in the hunt for proof that tyres are trending wider in racing, then the brand new Addict RC is one to take realize of. The geometry has been optimised round the usage of 28mm tyres on a 21mm rim, and all fashions come geared up as such.

The brand new Addict RC in comparison to the former technology. Most of the key numbers are untouched, however the motorbike has grown slightly for the larger rubber.

The ground bracket is now decrease, the fork is longer, the pinnacle tube is shorter and the chainstays have lengthened a slightly. That is all to permit for the larger rubber with out impacting at the dealing with. Simply how giant a tyre can the Addict RC are compatible? Smartly, this is one thing Scott isn’t striking a host on, but it surely looks as if 30c tyres will have to are compatible.

Moreover, Scott has made the are compatible of the Addict RC much more race-focussed than sooner than by means of lengthening the succeed in on maximum sizes. The ones in the hunt for a extra leisurely are compatible will have to search out the common and lower-cost Addict, which stays unchanged for 2020.

Using with Yates and Chaves

Product launches aren’t all the time the most productive venue for a complete check. You’re out in teams, regularly with a photographer getting snaps of you in ‘motion’. It leads to more than one stops, regrouping, and prerequisites a ways from optimum while you’re seeking to check a motorbike. So hands crossed that, someplace down the road, somebody right here at CT can get their arms on a long-term tester.

Alternatively, first impressions nonetheless rely. On this case, the Addict RC had me wishing I used to be more fit and sooner to squeeze out the entire efficiency it so obviously gives.

The Addict RC feels precisely how I need a race motorbike to really feel, however does it with simply the correct quantity of extra convenience and regulate.

Aero positive factors, low weight, integration of anything else that are meant to be hidden away, and making discs glance marginally interesting – that is the place efficiency developments are going. And as one of the vital first makes an attempt at combining these kinds of parts into an all-around race motorbike, the folks at Scott and Syncros have, in my view, hit the bottom operating.

Does it trip great? That’s a forged sure. Greater than anything else, the stiffness is blatantly noticeable while you first soar on. It’s exceptionally stiff. And it permits you to know. Actually, it was once the very first thing that each Esteban Chaves and Simon Yates discussed once I requested them what they considered the motorbike.

What had me stunned, and but, happy, was once the inclusion of 28mm tyres. That is, in spite of everything, meant to be a light-weight race motorbike. So shodding the wheels with what I’d magnificence because the broadest type of road-focussed tyres (anything else greater I’d magnificence as “all avenue”, which edges on gravel) is a daring transfer. It’s daring to construct the geometry round those tyres too. Everyone knows that there are some weight-weenies in the market, a lot of whom had been most likely enthusiasts of the former iterations of the Addict RC, and so they’d be guffawing to peer the Addict rolling on heavy 28s.

The bigger tyres haven’t taken away the Addict’s gentle feeling.

However the bigger-than-expected rubber presented a protected and sure footprint at the avenue. Now not as soon as did I believe I sought after additional oomph from the tyres; slightly the additional width and safety made me wish to throw the motorbike about slightly greater than I’d in most cases.

The bar form gained’t be for everybody. There have been various newshounds on the release who grumbled that the V-shape intruded on the place they’d typically position their arms when cruising. For my part, I discovered the bars to be among essentially the most comfy one-piece setups I’ve used.

The drops are reasonably shallow and no longer overly ergonomic of their form, protecting relatively a vintage drop. They jogged my memory of the FSA Compact professional, a bar form I’ve a sneaking suspicion is a template for plenty of producers in the market. I were given used to the tops temporarily, discovering them relaxed. The published grip was once a pleasing contact.

The brand new Syncros Belcarra Common semi stub-nose saddle was once but any other marvel. It’s a logo that hasn’t ever truly stuck my passion, however after this trip, I’m re-evaluating that opinion. I’ll have one on a long-term check so keep tuned for an replace there.

Extra to come back

Stiff and lightweight? Sure, it’s. At ease? Smartly, it gave the impression to tick that field too. Alternatively, it’s suitably comfy for racing, no longer staying power comfy. It is a motorbike that desires to be driven and it’ll kick you ahead because of this. But if it’s time to chill out, it’s glad to do this, too. It’s supremely neatly balanced.

However I merely didn’t get sufficient time at the motorbike to hit upon any problems or to notice nuisances. Optimistically, we will repair that within the close to long run.

As examined, the Final is alleged at 6.9kg, with the RC Top class (Dura-Ace Di2) quoted at 7.2kg. The most affordable model, the Shimano 105-equipped Addict RC 30 is quoted at 7.96kg. All figures are with out pedals. Fashions are anticipated to be in shops from September-October, and Scott will liberate pricing and ultimate specification on September 1st (no, this isn’t a funny story).
