The ORBEA OIZ M10 was introduced with the theme of "long ride x mountains." After completing a 400km long ride, it achieved a cruising speed of 30km/h, which is unbelievable for an MTB. Grumpy staff honestly review the capabilities of this versatile MTB, which comes standard with OQUO carbon wheels, the new SHIMANO XT, and FOX FACTORY suspension.
