The original purpose of the Oiz was to offer cross-country enthusiasts a full-suspension bike that was as fast, light and technologically advanced as possible. Today, the Oiz has a carbon monocoque frame which, according to Orbea, has been manufactured according to the latest standards and the most advanced technologies. For example, the pre-impregnated carbon mats are laser-cut to minimize excess material. A lengthy preforming process is used to achieve optimum compaction with the smallest amount of material. This means that only as much carbon as possible is used, resulting in weight savings. The complete frame weighs just 1600 grams.

One frame, two bikes

The suspension system consists of a UFO 2 rear triangle, Fiberlink and Fox DPS shock and offers 100 millimetres of suspension travel - ten millimetres more than the previous model. It should also be very drive-neutral. What is special about the rear triangle is that it consists of just one piece. And this is where the UFO technology comes into its own: as the rear triangle has no pivot points on bearings, the seat stays are designed to be so flexible that they can take over the task of conventional pivot points. This means less maintenance but also less weight.

Another detail: the lightweight Fiber-Link has its pivot point hidden at the bottom of the top tube. This gives the frame design its clean and compact look.

In addition to the XC version, Orbea also offers a TR version - a trail bike with 120 millimetres of suspension travel on the front and rear wheels. The Spaniards use the same frame for this. The differences can be found in the stroke. The shock has five and five millimeters more travel with the same installation length. As a result of the fork being 20 millimetres higher, the seat and steering angles are also flattened from 75 and 69 to 74 and 68 degrees.
The Oiz M10 TR also comes with slightly "tougher" specifications, such as more robust and wider tires.

This and that

On Orbeas Oiz, all cables and lines are neatly routed internally. The lockout control is also routed directly through the top tube and out of the headset. The frame is also designed for variable seatposts with internal cable routing.

The Oiz appeals equally to cross-country and marathon racers. For the latter in particular, the frame offers the option of mounting two bottle cages in the frame triangle from size M upwards.

The Twentyniner is available in frame sizes from XL in 21 inches to SM in 15.5 inches. As smaller riders often prefer small wheels, the latter frame size is also available in a 27.5-inch version.

Orbea now also offers the Oiz as a MyO. This allows you to put together and personalize your racing bike according to your colour preferences. The new bullets will be available from mid-September 2018.
