Orbea's Oiz updated for modern XC racing

New XC bike is slacker, longer and available in two travel options

Orbea has just announced an update to its full suspension XC-bike, the Oiz, with a number of interesting features. Primary among those are the ability to run the bike with either 100 or 120mm of travel and the ability to fit two bottles in the main triangle.

2019 Orbea Oiz highlights

  • Two Stroke design means same frame can be used for a 100 or 120mm travel build
  • Inside Line fully internally routed shock lockout in collaboration with Fox
  • Two bottles can fit in the main triangle (sizes M and up)
  • Full carbon frame
  • Enduro BO pivot bearings
  • Dropper post compatible
  • Available under Orbea’s MYO custom programme
  • 1x specific, all bikes ship with 12-speed SRAM or Shimano drivetrains (with SL chainguide)

All-new carbon frame

The updated carbon frame is made using Orbea’s OMR (Orbea Monocoque Race) construction. From our understanding, the construction techniques are fairly standard stuff with the carbon laid up around an EPS (Expanded Polystyrene) core.

Despite being increasingly common on high-end frames, Orbea also appears to be using vacuum debulking during the frame layup.

This essentially involves compacting the carbon layers each time a new layer is added, helping to consolidate the layers, removing any voids and removing air from the resin, making a stronger composite.

This technique is widely used in the aerospace industry but adds time and cost, which is why you currently only see it on high-end frames.

Updated suspension kinematics

One of the unique aspects of this bike is the ability to run either a 190x40mm or 190x45mm shock, with the option to run either 100 or 120mm travel at the rear. Orbea has dubbed this Two Stroke.

The suspension kinematics have also been updated slightly on the 2019 Oiz model to account for the additional travel on offer (up from the previous 90mm).

Orbea claims that the bike can be set up with low sag to maintain the bike’s geometry, but is able to make use of all of its travel thanks to its kinematics and the custom shock tune. The leverage ratio increases until the end of the shock stroke, where it is a falling rate to overcome the inherently progressive nature of an air shock. That comes with all the usual claims of being a very efficient setup for XC racing.

The suspension linkage — dubbed Fiberlink — is a lightweight 59g moulded carbon piece. The stays continue to make use of Orbea’s UFO system, which has forgone a rear pivot and instead allows the stays to flex as the suspension compresses.

The suspension hardware also uses a full complement of Enduro BO bearings in a bid to improve longevity.

In comparison to the 2017 model, the geometry of the new model is a bit more progressive: the 100mm travel version sees the head angle slackened out to 69 degrees, the seat angle steepened to 75 degrees, reach increased to 435mm and the chainstays shortened to 435mm.

As mentioned previously, this bike can be configured with either 100 or 120mm of travel. In the longer travel incarnation, the head and seat angle both slacken by one degree to 68 and 74 degrees respectively.

Orbea offers the size small Oiz with either 27.5in and 29in wheels to suit individual riders. All other sizes come with 29in wheels.

The frame weighs in at a competitively claimed 1.6kg in an unspecified size.

Internally route everything!

The new Oiz is 1x specific, completely internally routed and is dropper post compatible.

Orbea has an exclusive partnership with Fox for a proprietary shock lockout, which Orbea is calling Inside Line, that is fully internally routed.

This arrangement cleans up the frame and is part of the reason two bottles can be fitted (size medium and up).

MYO customisation options

The MYO customisation was first introduced on Orbea’s road bikes, but is now starting to expand to its mountain bike range.

It allows you to spec custom colours for the frame as well as make different component choices to get the build of your dreams.
