The Orbea Oiz cross-country bike is already light-weight, however the weight weenies at Brujula Bike couldn’t resist pushing the carbon XC bike additional to an entire bike weight with pedals and a bottle cage beneath 9kg. Orbea & Brujula admit they put plenty of unique ultralight carbon parts into the ultimate construct, however really feel assured these are all race-ready mods.

Orbea’s Oiz full-suspension XC race mountain bike is already identified for being mild with its newest 1350g OMX carbon body, and its light-weight short-travel 100mm full bike builds weigh as little as 10kg full with full XTR and carbon DT wheels. However that wasn’t sufficient for Brujulabike. Though they are saying, “it wasn’t sufficient to scale back weight at any worth. It needed to be utterly dependable for racing and with parts accessible in the marketplace. The result’s this spectacular full suspension MTB beneath 9 kg.”
They know you’ll be able to construct a sub 8kg XC bike in case you are prepared to sacrifice reliability, consolation, and even stratospheric costs. However Brujula wished their Orbea Oiz XC race bike to be prepared to tear!
Customized weight weenie construct particulars
Proper on Orbea’s claims, this dimension medium Oiz OMX frameset with its carbon rocker hyperlink and inline-mounted Fox Float DPS Manufacturing facility shock weighed 1740g within the lightest clear blue paint over uncooked carbon. Brujula paired that to a 1418g Fox 32 Float Step Solid Manufacturing facility fork, for 100mm of journey entrance & rear.
That’s just about the place inventory package ended.
The obvious improve are the 1376g Bike Forward Biturbo RS monocoque 6-spoke carbon wheels, which can be actually mild whereas being stiff, World Cup-proven & nonetheless 27mm extensive inner (despite the fact that we’ve seen a number of ~1kg XC wheels, even earlier from Bike Forward). Topped off with Pirelli’s Scorpion XC RC Lite 2.2″ XC tires with no protections (though I’d want the two.4″ model that’s simply 90g heavier a chunk with ProWall sidewall safety).
However in all probability simply as a lot weight is shed within the ultralight hand-laid carbon Darimo 93g T1 Loop seatpost with Dyneema rope saddle rail clamp, 62g stem & 108g flat handlebar. Prime that with a 70g full-carbon Saevid saddle, some Orbea foam grips to maintain the cockpit mild, a 224g pair of Exustar pedals, and Alpitude’s foolish mild Superleggero carbon loop bottle cage.
Brujula even shed some weight off the SRAM XX1 Eagle AXS drivetrain with Hopp Carbon hyperlink plates & a Kogel Kolossos cage for the rear derailleur, plus the ultralight, ultra-machined Ukrainian Garbaruk cassette.
And braking bought a lightweight improve with new Hope XCR stoppers, Ashima rotors & Kogel ti rotor bolts.
