If you are looking to get the lightest climbing bike you can find, you may be reluctant to go with disc brakes since they are naturally a touch heavier than rim brake options. But with the Orbea Orca OMR Disc, you can plum for the disc brake version because the frame is already so light. And the extra level of confidence the disc braking gives you will start to pay dividends as soon as you start to bomb down the descent that follows a long climb.
The OMR in the name indicates Orbea Monocoque Racing, which uses the top drawer Toray carbon to increase stiffness while keeping the weight super low. But with the addition of disc brakes, they have been certain to take into account the resulting forces that will be applied to the fork and rear stays in particular. Freeflow monocoque carbon fork works to absorb the vibrations before reverberating to your hands, while also providing one of the keys to the enhanced aerodynamics of this updated Orca. Its bow-legged shape calms the airflow between the rotating wheels and the interior of the fork blade. And the full carbon tapered steerer tube will ensure the front end feels super solid even when whipping it around twisty alpine descents, and the disc brakes will encourage you to push your speed, knowing you can count on the stopping power even in the hottest conditions. The race-oriented geometry will get you easily into your tightest tuck to make the most of your speed.
Building the frame out from the mega BB386 bottom bracket, the Orbea designers have made the head tube, down tube, and chainstays super resistant to torsional pressures so that there is absolutely no flex when you put the hammer down. Expert use of the Toray carbon, right down to laser cut prepreg carbon sheets, will ensure that the various high quality carbon fiber sheets are laid exactly where they will do the most good, while there using a minimum of material. But then the flip side of stiff for any bike must be compliancy and comfort. Orbea accomplishes this by adjusting the carbon layup for the super thin seat stays and elegantly shaped top tube so that they work together to dampen vibrations from the road.
Onto the practical touches, the 12mm through axles in the front and rear will work to keep that solid, secure feeling while you ride, and the 27.2mm diameter for the seat tube will make finding your ideal seatpost much easier. Internal cable routing for both mechanical and electronic groupsets will keep this machine looking slick no matter how you spec it out, and the frame has been designed with power meters in mind as well.
If you are looking for a great climbing bike that will also keep you safe on the way back down the mountain, the Orbea Orca OMR Disc will be a perfect option. Ready for the longest climbs and itching for the twisty descents, you will find even more pleasure in the pain.
