Up close with the Scope Atmoz tyre pressure management

Nearly on the eve of this year’s Paris-Roubaix, the UCI introduced the approval of a tyre force administration gadget from Dutch wheel model Scope Cycling. The incorporate-on system, priced at a whopping €4,000, provides tyre inflation and deflation at the touch of a button and on the go.

On the confront of it, the Scope Atmoz sounds a good deal like the KAPS hub dependent tyre stress management program from another Dutch model, Graava. Nevertheless, the way in which the two methods alter tyre strain and, crucially, the UCI acceptance for use in opposition the Atmoz now features, set the two on-the-fly tyre pressure administration devices aside.

CyclingTips caught up with Scope at Eurobike 2022, to get some far more data on what the Dutch brand is contacting a “significant gain” and “one of the most major innovations of contemporary cycling”.

How the Scope Atmoz works

The procedure is made up of a hub attachment housing the electronics, tyre pressure sensors, valve stem for reservoir inflation, exhaust for tyre force deflation, and a USB rechargeable battery. Two air lines run from the hub attachment, alongside the spokes, and into Scope’s proprietary valve stem.

The hub attachment communicates wirelessly with a communications box less than the stem, which in convert is wired to two front and rear inflation and deflation buttons on the handlebars. With these buttons, the rider can inflate and deflate their tyres at a level of .5 bar / 7.3 psi per 2nd, on the go and with out lifting their fingers from the handlebar.

Riders can also system the Atmoz with preset tyre pressures, and the system capabilities higher and lower restrictions adjustable in line with individual tyre and wheel pressure recommendations.

Scope experienced the intention of creating a straightforward immediately after-marketplace include-on program, suitable with just about any wheel. As an include-on process with no motor or pump, the Scope Atmoz does not incorporate any more friction or drag into the wheel process and is appropriate with a wheel or frame’s standard via-axle. Properly there is no alter to the wheelset setup.

On top of that, Scope claims the Atmoz is compatible with all 700C and 29′ wheelsets and any tubeless tyre and promises the entire method is really uncomplicated to set up.

Simplicity of use and UCI acceptance was crucial to Scope from the outset. As this sort of the Atmoz is appropriate with “almost any wheel”.

The Atmoz provides all around 300 grams to each individual wheel, so an extra 600 grams to the whole bike bodyweight and noticeably, the Atmoz is now UCI accredited for use in level of competition. While an added 600 grams is a hefty body weight penalty, in functions like Paris-Roubaix, in which Scope suggests the Atmoz is most valuable, the added body weight is a great deal less of an issue.

Scope claims the effectiveness gains are also significantly from marginal also, describing the claimed 20-30 watts gains around the cobbles of Paris-Roubaix as “significant gains.” People proposed gains are located in optimising tyre stress for racing across the tough stones, and so will fluctuate relying on the various pressures diverse riders pick for Roubaix.

Scope points to the gain of various tyre pressure for the particular person cobble and tarmac sections of the race as yet another big reward. Scope co-founder Nieck Busser implies the profit to a rider across an overall Paris-Roubaix, various the force up and down from sector to sector is all over ten watts. Whilst the improved traction and comfort supply even even more benefits.

The Atmoz relies on an inner rechargeable battery and the pre-loaded air reservoir to inflate the tyres, and as such will generally be constrained in the variety of inflation and pressure variances it can provide per ride. Busser suggests for a race like Roubaix on 30 mm highway tubeless tyres with 3.5 bar reduce and 5.5 bar higher stress presets, the technique is capable of 8 inflation and 8 deflations across the race. In races with smaller pressure alterations or decrease volume tyres, the amount of changes could be substantially extra.

Whilst, unsurprisingly, the Atmoz needs a tubeless tyre set up, it is not but appropriate with tubeless sealant. It is something Busser and the Scope engineers are performing on and hope to introduce before long, but it prospects to one more exciting query. Just wherever is the air reservoir?

Where’s the air?

Even with now getting commercially readily available, as expected by the UCI rules, for a cool €3,998.00 from ScopeCycling.com, Scope are retaining a number of tricks up its sleeve as to exactly how the Atmoz outlets air in the method.

The hub attachment houses the nozzle for including air to the reservoir, but given the dimensions of the attachment, it was never ever likely to be huge plenty of to retailer an air reservoir able of featuring major tyre strain alterations through a journey. Rather, Busser describes “the air is stored in in this article,” pointing to the rim.

“Inside the rim?” I check with.

“No, not within the rim,”

Ah, it is a tube inside of the tyre?” I question

“It’s not a tube. It’s still a secret” Busser points out.

“Compressed air?”

You now know in which the mystery is, but not what the mystery is.”

Busser explains the exact strategy for storing air is a little something Scope is quite very pleased of and is extremely simple to set up, but cannot disclose any even more data just but. This secrecy perhaps partly points out the humongous price tag tag. The Atmoz will have to be commercially accessible if professional riders are to race with it, and “as riders, we want it available for racing,” Busser points out. By pricing it at practically €4,000, Scope can have it commercially accessible and still be fairly confident in retaining their insider secrets from rival companies.

UCI does very well

The key-trying to keep price tag tag is not the only affect the UCI rules have experienced on the Atmoz method. Busser defined it was this UCI acceptance, so essential to Scope, which would grow to be the brand’s finest problem in acquiring the Atmoz. Scope quickly produced the initial idea, but as the UCI experienced no definitive regulations governing tyre pressure management systems, Scope initial experienced to establish what specifically would acquire acceptance from the UCI and then perform to acquiring that.

Rider basic safety, compatibility, reasonable opposition, and availability to all teams were vital details for the UCI, who insisted no motors or pumps could at any time get acceptance. For Scope this meant a a great deal longer structure and development obstacle that pushed the brand’s engineers and finally two UCI knockbacks before the closing structure was accepted.

Now, as Scope unveils its permitted Atmoz, Busser is adamant the UCI’s needs pushed the model to finally build a a lot superior technique with bigger compatibility and trustworthiness. Generating a tyre stress management procedure the UCI could approve took extra than two a long time, with the remaining approval arriving just a week out from Paris-Roubaix.

The approval was not only brief detect forward of Paris-Roubaix, but the UCI, fearing another Matej Mohorič San Remo dropper post “is that legal” saga, considerably stole Scope’s thunder by saying the approval of the Atmoz tyre strain administration process in a push release.

Busser clarifies the information arrived much too late for this year’s Paris-Roubaix, as Nils Eekhoff, the only rider who had earlier thoroughly tested the process, was out with a damaged collarbone. Eager to avoid any possible PR catastrophe in acquiring riders unfamiliar with the Atmoz race just one of the toughest, best strain races on the earth, both Scope and Team DSM opted not to use the Atmoz in this year’s Queen of the Classics.
