Dangerholm is back with a new build, and this time the Swedish super-bike creator has produced a sub-5-kilo Scott Addict RC.<\/p>\n
The bike takes a stock Scott Addict RC frame, already a lightweight climbing bike to begin with, but then takes the spec list to the extreme to pursue the goal of creating the most \u201dnormal\u201d lightweight road bike ever.<\/p>\n
There are lighter bikes that might appear at UK hill climbs and other climbing-specific events, but this design is intended to be a fully fledged high-performance road bike that weighs less than 5 kilograms.<\/p>\n \u201cIt could be argued that the age-old quest for lightweight road bikes has taken a bit of a backseat position in the last decade or so,\u201d Gustav Gullholm, the person behind Dangerholm, said in the press release. \u201cWith the rise of aero bikes along with new trends such as wider tires, shorter cranks, and narrower handlebars, the classic \u2018weightweenie\u2019 focus simply isn\u2019t as hot as it once was.<\/p>\n \u201cBut interestingly enough, there has never been a better time for lightweight bikes than now.<\/p>\n \u201cNot to build the lightest bikes ever, perhaps, the days of rim brakes and narrow tires had some benefits in this regard. But never before could you build a really lightweight bike with such performance and ride quality as you can today.\u201d<\/p>\n In addition to the incredible lightweight construction, the Dangerholm Sub Five Scott Addict has a full custom paint-scheme, as all Dangerholm creations have, with this bike featuring a black and white motif that is reminiscent of tattoo design.<\/p>\n Dangerholm is the persona of Gustav Gullholm, who is a Swedish master bike mechanic. Over the past few years, Gullholm has become a niche internet bike celebrity through the Dangerholm brand as he continues to push the limits of bike construction and aesthetics across the cycling spectrum.<\/p>\n These include the newest Scott Addict RC project, but also an extensive collection of mountain bikes, gravel bikes, and unique combinations of the two genres. Pursuing light bikes is a key component of his custom builds, as he claims to have made the world\u2019s lightest XC bike and the lightest 29\u2033 DH bike.<\/p>\n Dangerholm and Scott have had a long-term relationship, as several of his souped-up custom Scott builds have escaped containment and gone viral in the bike world for their unique construction and striking looks. None more so than his Scott Scale RC Aero gravel race bike.<\/p>\n That build took a conventional Scott Scale Gravel, a gravel-oriented bike with a MTB platform with flat handlebars and a rigid fork, and transformed it. The final result was a gold-painted, drop-bar aero gravel racing machine, including massively wide rims with an inner width of 45 mm, an outer width of 52 mm, and a depth of 70 mm. All of this was configured to create the perfect monster-truck aero gravel racing bike that would bring a whole new level of speed to a gravel bike built around 2.25\u201d tires.<\/p>\n While the Scott Addict RC released today is less of a departure from the norm than the Scott Scale, it is still very much a Dangerholm creation. Dangerholm is all about creating one-of-one bikes where every detail is carefully picked to meet a clear aesthetic or performance goal.<\/p>\n For the Scott Addict RC Sub Five project, instead of finding the absolute end of the spectrum of light bikes, Dangerholm gave himself the task of finding the limit within his own parameters of what a good bike may be.<\/p>\n In addition to the bike having to weigh in at less than five kilograms, the bike also needed to check off the following list of demands:<\/p>\n These are the key specifications that make this bike impressive. Instead of the Frankenbike creation made for hill-climbs, these restrictions are Dangerholm\u2019s personal needs to have a bike that he himself would want to ride. It is also worth noting that this bike was made to fit Dangerholm, who weighs 80 kilograms (176 lbs) and is 183 cm (6\u20191\u201d) tall.<\/p>\n Here is the full spec list of the bike, including the weight of each component that make up the 4,991.4 grams, or 11.0 pounds, of bike weight.<\/p>\n Frame:<\/b> SCOTT Addict RC HMX-SL L\/56cm \u2014 630.9 g<\/p>\n Fork:<\/b> SCOTT Addict RC HMX-SL \u2014 282.4 g<\/p>\n Headset:<\/b> Syncros \u2014 48.3 g<\/p>\n Spacers\/cover:<\/b> Syncros and Darimo \u2014 22.5 g<\/p>\n Handlebar combo:<\/b> Darimo Nexum Drag 100x360mm -6 degrees \u2014 212.4 g<\/p>\n Bar tape:<\/b> Ciclovation KOM with Extralite HyperPlug HD \u2014 16.8 g<\/p>\n Brakes:<\/b> SRAM RED AXS \u2014 632.9 g<\/p>\n Rotors: <\/b>Carbon-Ti X-Rotor SteelCarbon 3 160\/140mm \u2014 146.5 g<\/p>\n Adapters: <\/b>Bike Ahead Composites The Fixer + Carbon-Ti steel shim \u2014 39.3 g<\/p>\n Rear derailleur:<\/b> SRAM RED AXS \u2014 276.7 g<\/p>\n Front derailleur:<\/b> SRAM RED AXS \u2014 171.6 g<\/p>\n Chain: <\/b>SRAM RED \u2014 231.0 g<\/p>\n Cassette:<\/b> SRAM RED 10-30T \u2014 194.9 g<\/p>\n Chainrings:<\/b> Carbon-Ti X-CarboRing X-AXS 50-37T \u2014 139.8 g<\/p>\n Cranks:<\/b> GrigioCarbonio Road T1000 170 mm \u2014 256.3 g<\/p>\n Bottom Bracket: <\/b>Extralite Hyper BB Ceramic (incl. brake hose guide) \u2014 38.9 g<\/p>\n Pedals:<\/b> Wahoo Speedplay Nano (tuned) \u2014 150.6 g<\/p>\n Wheels:<\/b> NonPlus Primaro Fusion hubs, Light Bicycle Airia 32 rims \u2014 866.7 g<\/p>\n Tires: <\/b>Schwalbe Aerothan 29 mm \u2014 342.5 g<\/p>\n Tubes: <\/b>Tubolito S-Tubo-Road \u2014 41.0 g<\/p>\n Seat post:<\/b> Darimo \u2014 117.7 g<\/p>\n Saddle:<\/b> Gelu K3 \u2014 39.2 g<\/p>\n Bottle cages: <\/b>CarbonWorks including bolts \u2014 19.4 g<\/p>\n Computer mount:<\/b> Alpitude including bolts \u2014 16.5 g<\/p>\n If you want to learn more about the Dangerholm experiment, check out our podcast with the man himself here.<\/p>\n<\/div>\n [analyse_source url=”https:\/\/velo.outsideonline.com\/road\/road-gear\/dangerholm-strikes-again-sub-5-kilo-scott-you-want\/”]<\/p>\n","protected":false},"excerpt":{"rendered":" [analyse_image type=”featured” src=”https:\/\/velo-cdn.outsideonline.com\/wp-content\/uploads\/2026\/03\/Dangerholm-Scott-Addict-Rc-Cover.jpg”] Logan Jones-Wilkins Published March 23, 2026 09:00AM Dangerholm is back with a new build, and this time the Swedish super-bike creator has produced a sub-5-kilo Scott Addict RC.
