Tech Roundup: Scott Dangerholm Contessa Addict Gravel, Suplest Edge+ 2.0 shoes, Sella Italia SLR Boost 3D saddle and the Vello Sub e-cargo bike


Trying to reduce the weight of a bicycle is one of the centuries-old traditions of cycling. Whether you’re reducing a bike to its essence for a hill climb (opens in a new tab)or just looking to make your trusty steed a little livelier, chances are we’ve all looked to shave a few grams off a build at one time or another.

Gustav Gullholm, better known in cycling circles as Dangerholm, turned weight saving into an art form and here we present another of his masterpieces. Vello, who operates in a different cycling sphere than Gustav but is no less ingenious for that, is also looking to fight the scales by designing an electric cargo bike that doesn’t weigh the same as a hippo.

Selle Italia and Suplest are getting in on the action with a 3D-printed saddle and line of road shoes that appear to have many attractive attributes, including being light enough to appeal to all heavyweights.

Gustav Gullholm, aka Dangerholm, is renowned for his exotic and lightweight custom builds. In search of a lighter bike, the Norwegian (who lives in Sweden) will strip paint with a knife and modify components to the nth degree, looking to save grams where possible.

He has built mountain bikes that are the lightest in their class and has now successfully assembled a Scott Contessa Addict Gravel bike for his partner Pernilla Eriksson which tips the scales at just 7.49 kg or 16.51 lbs.

For Eriksson, the bike was a “dream build”, so nothing was left to chance. Highlights include Unique Pi Rope wheels, which use Vectran fiber rope spokes in a custom dyed pink, CeramicSpeed ​​OSPW in Cerakote White and a custom groupset including Easton EC90 SL carbon cranks, Garbaruk 42T chainring and a SRAM X01 rear derailleur that’s been upgraded with a carbon fiber cage and titanium pins. Even the Shimano pedals are limited edition, with titanium axles and ceramic bearings. We stayed ‘no stone’!

The bike is finished with a paint job that Gullholm describes as “liquid purple over metallic pink” to complement the glossy carbon fiber. Eriksson hopes his “dream” will inspire others to do the same.

“It doesn’t matter if it’s getting your new dream bike from your local bike shop, getting fully customized like this, or just getting a small but nice little upgrade for your old bike. faithful training,” she says. “Having a bike that evokes feelings, that makes you happy when you look at it, is something that can just bring even more joy to your life as a cyclist.”

Suplest offers Swiss precision for your feet

Suplest Edge+ 2.0 Road Shoes

You’d be forgiven if you haven’t heard of Suplest. The Swiss company calls itself “one of the smallest cycling shoe brands in the world” after all. But they’ve been quietly making premium kicks for over a decade and recently launched a new line, the Edge+ 2.0.

The range consists of four road shoes, each with a specific target audience, with matching materials and performance details.

Suplest says the Edge+ 2.0 Road Sport is designed for those who want “high quality at a good price point”. This roughly translates to “entry level”, but being a Suplest shoe, it still means an L6 Boa dial and a clean looking microfiber PU upper, which comes with a responsive outsole that isn’t too stiff .

A step up is the Edge+ 2.0 Road Performance model. Aimed at endurance cyclists, it features a BOA Li2 dial, carbon outsole and the brand’s combination of anatomical wrap-around tongue and carbon shield construction designed to improve fit, comfort and foot support.

It’s a technology that’s also shared by the Road Pro shoe, but here you get an extra Boa dial and a carbon outsole that Suplest rates at 10 on the stiffness index.

The Road Pro 30.8 uses many of the same features, but is designed for hot weather and steep climbs – the Matryx material, which contains kevlar threads, helps reduce the weight of the shoe to less than 240 grams.

Selle Italia’s iconic SLR pole goes 3D

Three-dimensional printing continues to gain a foothold in the cycling industry. From Filippo Ganna Pinarello’s record (opens in a new tab) to Silca’s titanium Chisela computer stand, more and more brands are turning to this technology. And now Selle Italia is having fun.

The famous Italian brand has been making some of the best saddles for over 120 years, with its Flite and SLR models achieving iconic status along the way – and it’s the SLR Boost that gets the 3D treatment here.

Available in two versions, one with carbon rails and one with titanium, the saddle’s 3D printed cover has been developed using DLSTM carbon technology and uses a proprietary textured pattern which, according to Selle Italia, has “differentiated zones that create progressive cushioning over the entire surface”. .

It also uses the brand’s Superflow hole, a decompression channel, and comes in two widths, the S3, which measures 130mm and the L3, which measures 145mm. Both are 248mm long. The result is a saddle entirely made in Italy.

Crowdfunded e-cargo bike that hopes to punch well above its weight

Vello SUB E-Cargo Bike

Electric cargo bikes are awesome. But they are also damn heavy. Vello, the company behind the folding electric bike, the Vello Bike+, and concept cargo bike, the “Biquattro”, is looking to change that with the announcement of the SUB smart utility bike.

The SUB, which will be available for pre-order via the crowdfunding site indiegogo, will be offered in two versions, titanium and chromoly steel. The titanium model has a claimed weight of just 24kg, while the steel-framed model is said to weigh 28kg. For comparison, the GSD S10 from Tern (opens in a new tab)which we consider to be one of the best e-cargo bikes (opens in a new tab)available, tips the scales at 33 kg.

Vello claims that the low weight of both models is achieved through its “minimalist and pure approach to design, stripping all unnecessary weight from the frame, then pairing it with some of the best components available”. These components include Bosch’s Cargo Performance Line motor, which delivers 85Nm of torque and is powered by two 500Wh Bosch batteries and a Gates Carbon belt drive paired with an Enviolo internal gear system. Combined Vello says this will mean “virtually maintenance-free transmission with a 380% gear range.”

Given its low weight, it’s no surprise that the SUB is rather small; its length of 180cm should, however, make it easy to maneuver while allowing it to be taken on a train or installed on a bicycle rack. To aid in this portability, the SUB uses collapsible handlebars and folding pedals to reduce its overall width to 29cm.

However, none of this seems to comprehend the SUB’s ability to haul cargo. Vello says the total system load of 210kg means it can be a real replacement for the car. The tool-less quick-release accessory system also means you can change the configuration of the SUB, as well as adding child seats and cargo baskets.

The Vello SUB is available for pre-order now, with an expected delivery date of fall 2023.
