The 27.5” (650B) hardtail for racetrack and singletrail.
Since the laws of physics say that force is the product of mass times acceleration, then here is the result for bikers: the lighter a bicycle is, the more quickly it can move. This is a good reason, not only for racers, to think about using a 27.5” (650B) hardtail – but certainly not the only reason. Similar to its “big brother” BIG.NINE, the BIG.SEVEN wins you over with a smooth ride, modern comfort and powerful traction on rough terrain. These are precisely the qualities that give the “bike in the center” its advantages compared to the MATTS 26 incher.
Since 2014, we have positioned the BIG.SEVEN precisely between our 29er BIG.NINE hardtail and MATTS, the 26-inch aluminum classic. But it is not exactly the middle of the wheel sizes that make a 27.5” bike interesting: a diameter of 25 mm separates the BIG.SEVEN from the MATTS, and a further 38 mm from the BIG.NINE. This is precisely where advantages can be found, especially for beginners and hobby racers: since mainly the wheels determine how quick a bike can be, they should be as light as possible – it is obvious that small wheels have to be lighter than big ones. Therefore, the BIG.SEVEN really does combine the best of both worlds; it rides more smoothly than a 26 incher and has a weight advantage over a 29er. And because this concept is a real winner for the BIG.SEVEN, the changes for 2016 are limited to the equipment: first and foremost, the top-model BIG.SEVEN 9000 looks brilliant with Shimano’s XTR Di2 drivetrain and the 100mm suspension fork RS-1 by RockShox. New seat posts with a 15 mm offset make the seating position of all CF and LITE models less aggressive.
