XC racing is back - big time! With the way the courses have developed it's fun to watch and fun to ride. Despite this almost all bikes on the market in this category have the same old-school geometry that hasn't changed for years. Bikes in all other segments have developed and designers and riders have realized that longer reach, steeper seat angles and slack head angles create a unique combination that makes the bikes faster and easier to control. When we started experimenting with this geometry in prototype XC race bikes, we got results that we expected on the gnarly, downhill sections - these bikes were simply on another planet compared to anything else on the market with this amount of travel. But what we were most surprisedto find is that the bikes also climbed better, and were super fast on the flats! The former is mainly due to the fact that the riders is sitting more in front of the rear wheel and the weight distribution is better when the road points uphill. The latter is a result of the possibility to lower the cockpit and place the rider in a more aggressive, aero position without the bike feeling sketchy on the downhills. We have asked many experienced XC racers to test this bike on their favorite courses and there really is no doubt as to how fast this bike really is. They managed to make massive improvements on segments that have been attacked by them hundreds of times on their 'normal' bikes.

Before you say: “WTF?! Is NS making an XC bike??” - stop. This is NOT just another XC bike. This is something completely different! The geometry of the Synonym is MILES away from any bike that you can find on the market. The the slack head angle, massive reach and very steep seat tube this bike descends better than any XC bike out there, it climb like a goat and charges like a bull on the flats. We deeply believe that short travel hardcore, lightweight XC / Trail bikes are the most fun you can have on two wheels when you don't have a chairlift. This year many companies have launched bikes in this category, but even if they claim to be progressive, they are actually very conservative old school XC bikes with bigger forks. The Synonym is different - it's a totally new concept designed from the ground up. Everyone we know who has tried this bike has been simply blown away. This really is a game changer in the XC / lightweight Trail segment.
