Occam TR 2017

Orbea Occam TR M10 2017

In this article we talk about the Occam TR M10 2017, Orbea’s trail bike. It is one of the bikes we used during our first Trans Pyrenees allmountain adventure where we verified that the Occam is the perfect weapon for the wildest mountain bike adventures.

Orbea Occam TR M10 2017

The Orbea Occam TR 2017 is a double suspension trail bike with 120mm travel and 29” wheels. The TR is the trail version of the Occam and is a balanced bike that has been designed for those mountain bikers who want a capable bike on the descents without almost loosing rolling efficiency (climbs like a cross country bike). The 29” wheels, the 120mm travel lockable suspensions and the light carbon fibre frame make the TR M10 a really versatile bike. The Occam TR rolls efficiently on the climbs and the flat sections, it is very stable and transmits an exceptional control on the most technical downhills.

Occam TR carbon frame

The Occam TR M10 frame is built with high quality OMR carbon fibre. It is an incredibly light monocoque frame with a beautiful shape. The rear stay has been built in only one piece with the UFO technology. That technology allows to take away the pivot point on the rear axle, making the bike lighter and stiffer. Furthermore, the rear axle is now longer (148mm) and wider (12mm), allowing the Occam TR to mount wider hubs with Boost technology. This technology makes the wheels stiffer, very important especially in 29” bikes.

Occam TR M10 Components

The Orbea Occam TR M10 2017 bike has a 120mm travel Fox Float 32 Factory Kashima fork and a Fox Float DPS Factory Kashima rear shock. Both suspensions work with air and use a 3-position damper that allows setting the suspensions easily. The fork and the shock have a small lever with three different positions: Climb, totally blocks the suspension, ideal for long climbs and flat sections; Trail, medium softness, perfect for singletracks and doubletracks sections with short climbs and downhill sections; Descend; soft compression, ideal for rocky and downhill sections.


The TR M10 is fully equipped with the Shimano XT M800 1×11 transmission groupset. The XT groupset includes: XT shadow plus rear derailleur, SL-M8000 rapid fire shifter, 32t chainring, 11-46t cassette and XT crankset. The brakes of the Occam M10 are also the Shimano XT-M8000, they come with a 180mm disc in the front brake and a 160mm disc on the rear one. This is without any doubt one of the most popular groupsets among the mountain bikers because of its simplicity and top-end performance.

For the handlebar and the seat area Orbea has mounted the Occam with the following components: Race Face Turbine dropper post, Race Face Next SL carbon handlebar, Race Face Aeffect stem, Race Face Half Nelson grips and Fizik Gobi saddle.


Orbea trusted on DT Swiss for the wheels of the Occam TR M10, this bike is equipped with DT Spline X-1700 29” wheels and Maxxis Ardent 2´4 tyres.

Who is the Occam TR for?

In our opinion the Orbea Occam TR is for those bikers that want a bike that does everything. Could be a great option for those who only want to have one mountain bike. The Occam 2017 is a bike that climbs efficiently while still allowing to have fun on the downhill sections. Therefore, we think that it is the perfect bike for the riders that like doing long routes that go through many different kind of terrain and trails. Or, for those who want a bike that provides confidence and reliability on the downhill sections without losing rolling efficiency.


For those who are looking for an aggressive bike to shred on the most difficult downhills the TR is not the best option. The TR works fine on the downhill sections but, its elder brothers, the Occam Am and the Orbea Rallon, with longer suspension travel and slacker headset angles are better for that.


Now, when pedalling on varied terrain, none of the other Orbea’s beat the TR 2017. Rooty singletracks, rocky sections, long climbs, steep downhill sections…the TR cope with everything. We used this bike on our first Trans Pyrenees allmountain adventure and we were super surprised with its performance.
