Pauline Ferrand-Prévot claimed the inaugural Elite Women's World Gravel Championship on Sunday. Amazingly, it was her fourth world title of the year after her three in mountain bike cross country, short track and marathon events. She has previously held the title on the road and in cyclo-cross too.

Ferrand-Prévot sprinted to the win on the recently-launched BMC Kaius 01 One gravel bike, which sits firmly at the racing end of the gravel bike spectrum and takes aero cues and technology from elsewhere in the BMC range. We take a dive into the spec and tech details of the bike.

The BMC Kaius 01 frame was released in late September and was ridden by several BMC athletes at the Gravel World Championships.

You can't miss the familiar BMC styling, and the Kaius 01 features aero integration and the same aero bottle cages found on BMC's road models, like the TeamMachine, but with wider clearances for tyres of up to 44mm widths.

Ferrand-Prévot rode a size 47cm frame with the integrated cockpit pretty much slammed with no spacers under the stem. The Kaius 01 One model looks only to come in the white/black colourway pictured currently but don't be surprised to see a custom paint job for the world champion next year.

The finishing kit for the frame is partly included in the frame 'module' from BMC. An ICS carbon fibre aero cockpit takes care of the steering, with the setup featuring full internal brake hose integration for a super clean front end. The bars are only available in one width across all stem lengths, flaring from 36cm at the tops to 42cm wide at the drops. The seatpost is the Kaius 01 D-shaped carbon fibre post which is frame specific and features a 15mm offset. The frame also comes with BMC Aerocore bottle cages.

The groupset fitted to the bike is a SRAM Red eTap 1x wireless electronic affair, with what looks to be a SRAM Red AXS XPLR gravel derailleur which can accommodate a 44-tooth rear cassette. Ferrand-Prévot's bike was fitted with a 40-tooth narrow wide chainring for the race.

The crankset is carbon fibre with a Quarq power meter unit. The design of the crank arm looks a little different to anything on the SRAM website, with large SRAM lettering instead of the more subtle silver logo found on most options. This was also spotted on Mads Pedersen's bike at the Tour de France and could be a pro-only unit from the athlete-only 'blackbox' project. Ferrand-Prévot has had similar blackbox cranks on her mountain bikes this year also.

Wheels are taken care of by Duke Racing, a french company hand making all of its wheels and rims in-house. They are fitted with Vittoria Terreno Dry gravel tyres in a 35mm width, set up tubeless. Prologo takes care of the handlebar tape and saddle.

Finally, possibly due to her size 47cm frame having too short of a headtube, Ferrand-Prévot's mechanics didn't wrap her race number around her headtube, an aero gain employed by many riders, instead zip tying it around the bars, they did make a neat cutout for her computer though so her view wasn't interrupted.
