The Oiz M20 makes FOX Factory suspension the centrepiece of its OMR carbon build. Its 34 Float SL Factory fork and Float SL Factory shock give 120mm travel front and rear, with Squidlock controls and an OC MC22 dropper for changing terrain.
Underneath those components is an XC chassis designed to keep the rear tyre working on rough climbs, alongside space for two bottles on every size. Shimano XT shifting and cranks are paired with MT600 brakes and OQUO MP28PRO wheels. It is a useful choice if suspension specification takes priority and you prefer a conventional bar-and-stem setup.
The riding photograph shows a campaign Oiz on a wooded trail. The colour choices and specification describe this build.

A direct route to the shock
I-Line takes the shock control cable through the frame to the remote, keeping the route short and sheltered. Fewer exposed cable sections help keep the control arrangement tidy on a bike built for repeated use off road.
The cutaway shows the cable route on a FOX-equipped Oiz. The specification lists the shock fitted to this build.
Keep the rear end working in line
A forged aluminium link works with a seatstay bridge ahead of the seat tube to keep the shock and rear triangle aligned under load. The design brings the suspension structure together without relying on a bulky link.
Carry two bottles on the bike
Every size has two bottle mounts, making it easier to plan a long ride or race with water on the frame. It is a useful detail when you would rather leave a hydration pack at home.
The bottles and cages pictured are sold separately.
Traction with the shock open
Orbea uses a regressive suspension layout to balance pedalling support with grip on rough climbs. The intention is to keep the rear tyre working when the shock is open, so uneven climbs remain part of the suspension brief.
