BMC rolls out the super-lightweight Kaius 01 alongside the forefront of the gravel world. Integration in all places, inside cable routing, and carbon layup tooled to take some punishment headline the construct.
BMC’s new gravel bike goals at excessive efficiency and has the specs to replicate it. The corporate seems to be to have made heavy analysis and design funding into the Kaius 01, and if nothing else, it weighs subsequent to nothing.
The Kaius 01 comes with a carbon layup designed to guard the bike from rock strikes in weak spots, stealth cable routing and dropouts to scrub up visible and aero traces, geometry it says improves compliance and stiffness on gravel, and an built-in frameset that weighs lower than 4 kilos (claimed).
BMC Kaius 01: Design Drives Pedigree
BMC says the full-carbon built-in body, seat submit, cockpit, and fork weigh 1.785 kg or 3.93 kilos regardless of the bolstered areas. Excessive-module (learn: stiffer, however probably extra fragile) fibers, in keeping with BMC, improve stiffness however steadiness out the burden sacrifice from the heavy layup under. The “areas uncovered to rocks and shocks,” BMC mentioned, get bolstered to guard in opposition to impacts.
It’s a part of BMC’s “Tuned Compliance Idea” (TCC) methodology, which it deploys to take care of varied floor varieties and using kinds. The Kaius 01 gravel construct interprets to a entrance wheel bumped barely ahead for stability and traction on free terrain and a extra prolonged attain.
It additionally makes use of a D-shaped seat submit so as to add compliance as a result of it may flex backward farther alongside the 2 90-degree angles. The ultimate TCC contact is 10mm suspension journey. That’s roughly as refined because the elastomer on a skateboard truck however may show precious on bumpy excursions.
The built-in cockpit weighs 315 g; the body suggestions the size at 900 g (claimed). Extensive tolerance on the fork and seat stays make room for fats 44mm tires.
You’ll be able to customise the rig to a variety of experience distances and functions through the use of a dropper submit, a 1x or 2x chainring, or bolt-on body baggage. And 12.5-degree flared drops promote management when pedaling exhausting, and a brief stem ought to ship responsive dealing with.
The Kaius 01 lineup — beginning with the range-topping “One” and tuning all the way down to the Three — will get an digital SRAM drivetrain within the Pink, FORCE, or AXS line, relying on spec.
The One rolls on Zipp 303 Firecrest tubeless rims. 5 sizes starting from 47 to 61 cm on the seat tube. The road begins at $5,499 MSRP and tops out at $11,999.
