Dangerholm’s latest creation is this 9.19kg Hypersonic Scott Spark RC build with a custom paintjob.

The bike features a delectable selection of components from SRAM, Extralite and Intend.

Dangerholm is the pseudonym of Gustav Gullholm. He’s famed for creating super-light builds with custom resprays, taking a Mora bushcraft knife to new frames to carefully remove the paint.

Manually stripping away paint is a more laborious process than sandblasting, but offers a better finish.

“My goal for this build: quick and responsive on the climbs, fast and fun on the descents. In short – the best of two worlds,” Dangerholm says.

We caught an early glimpse of this build at Eurobike 2022, but now we’ve been provided with further details, let’s feast our eyes on every juicy detail.

A carbon weave finish frame with a pink front end

A size large Scott Spark RC frame is at the heart of the build, proving a very different result from Nino Schurter’s rainbow-infused Spark RC from earlier this year.

The Spark RC is notable for its integrated aesthetic and hidden shock design. This particular build features 120mm of suspension travel front and rear.

Dangerholm has, of course, taken his bush knife out and the frame is predominantly a bare carbon finish from the top of the down tube to the rear dropouts.

The exception is the Scott graphics on either side of the down tube, which are silver and look to be a foil paper design.

There are gold and silver triangular details along the top tube with thinner black arrows separating them.

The head tube and half of the top tube is a gloss pink with a fleck to give the frame an added sparkle under the sunlight.

Dangerholm has also resprayed the integrated bar-stem to the same pink shade to sustain the aesthetic up-front.

Various brand logos are featured along the outside faces of the driveside seatstay and the driveside face of the seat tube, in line with the bottle cage bolts.

Dangerholm has also made a couple of changes to the frame hardware.

Kogel Ti titanium bottle cage bolts are used to shave some weight and the removable lever on the thru-axle has been removed. The chainstay protector is also said to have been slightly cut.

A conventional groupset with some unconventional modifications

The industrial-looking Garbaruk crankset contrasts against the carbon weave finish of the frame.

The groupset is predominantly SRAM Eagle XX1, although interestingly in mechanical rather than its wireless electronic format. SRAM Eagle XX1 eTap AXS is claimed to be 5g lighter than its cable-operated counterpart, including the batteries.

However, Dangerholm has made some striking changes and deviations to the groupset to achieve a lower weight.

A prototype Garbaruk crankset is used with a 175mm length and a 40-tooth chainring. This is claimed to weigh in at 384g.

A Rotor 11-46 cassette is also used rather than the standard SRAM 10-52t.

Dangerholm says the Rotor cassette’s 11t starting cog offers slightly less friction than the 10t used on a SRAM cassette.

The steps between gears on the 11-46t cassette are also smaller compared to the larger SRAM cassette.

The rear derailleur has also seen heavy modification.

It uses Kogel Kolossos oversized pulley wheels that have been finished in a Champagne Pink Cerakote coating.

Kogel has also supplied a matching custom-made cage in raw aluminium.

Dangerholm has shaved weight by polishing the B-gap adjustment bolt.

He has also removed the cover from the pulley the gear cable passes through in between entering the rear derailleur and being clamped at the pinch bolt.

The stock parallelogram plates have been switched in favour of aftermarket carbon parts from Hopp.

Rather than use SRAM’s gear cables, Dangerholm has opted for FASI Turbo Plus, one of the lightest options. Regular cables use a steel core, whereas the FASI options use aluminium, resulting in a claimed 50 per cent weight saving.

A Jagwire LEX SL cable is used for the dropper seatpost and suspension lockouts.

Dangerholm’s Scott Spark RC build spec

Like the groupset, the rest of the parts spec is anything but conventional.

An Intend Samurai XC suspension fork with inverted stanchions is used. This is said to weigh 1,435.5g.

The bike features feathery Trickstuff Piccola Carbon brakes with matching Dächle UL rotors. Titanium bolts secure the calipers and discs.

As for the wheels, Radsporttechnik Muller MXCR rims are laced with Sapim CX Super spokes to Extralite HyperBoost3 hubs. They are shod with Pirelli XC RC Lite tyres in a 2.4in width and are set up tubeless.

The saddle is a Tune Speedneedle in a raw finish. This is secured to a YEP Podio dropper seatpost, which features a modest XC-friendly 80mm drop.

Dangerholm has substituted the stock Scott seat clamp for an Intend Corona. This is said to weigh just 9.6g.
