NS Bikes Synonym RC 2 2025 Bike

When we launched the synonym two years ago, many doubted its viability. Its ultra-slack head angle, massive reach, and steep seat tube were unprecedented in short travel bikes, especially for xc racing. However, the synonym signaled a new era in bike design. Today, we see that progressive geometry is crucial even for xc. The synonym rides like an enduro bike on descents, climbs efficiently, and speeds across flats. Our prototypes exceeded expectations on downhills and also excelled on climbs and flats. This is due to a better weight distribution and a lower cockpit position, which enhances both climbing and stability. The rc range, designed for xc racing and marathons, features a lightweight full carbon frame with flex stays, a flat bar, cross-country tires, and 100mm of travel front and rear, making it a versatile choice for serious riders.

Features

Radical, Unprecedented Geometry

The longest, slackest XC bike on the market! No other bike comes even close!

Flex Stays

Flex stays eliminate the need for a pivot in the rear triangle. Less weight, more lateral stiffness.

Frame Design
