Remember how we said Unbound Gravel has quickly become a hotbed of new and unreleased tech? This year has already brought what appeared to be a new Specialized Diverge gravel bike. Now comes an Orbea gravel bike we’ve never seen before, here under Pas Racing’s Morgan Aguirre.

There’s not a lot here that lets us know what model this is, but there are a few key bits that help us figure out that this is a new gravel bike from Orbea.

Tire clearance looks quite maxed out here. Morgan is running a 700c x 45 mm Schwalbe G-One R Pro out back, with decent tire clearance out back. Up front, however, the 50 mm tire is quite tight. That might be enough clearance for a dry race, but this tire is simply too wide for anything but a dry Unbound course. Morgan said they’ll look to try out a narrower tire front and rear to ensure they can roll through the expected mud more easily.

The bike is set up with a SRAM XX Transmission derailleur, indicating this Orbea features a SRAM UDH (Universal Derailleur Hanger). Further, the seat post clamp is hidden and seemingly tucked behind the round seat post, completely different from the seat post wedge system used on the existing Terra.

The fork blades feature a small fin profile, which brands like Pinarello employ as a claimed performance benefit. The fork crown flows neatly into the sculpted downtube, while the seat stay cluster has a much sharper profile than the existing Terra.

As for Morgan Aguirre’s bike build? Here are the details below. Cool bits include the use of a Ceramicspeed OSPW X pulley system and bottom bracket. Otherwise, the bike is fairly straightforward.
