Norco has redesigned their 650b all-mountain bike into a lighter, stiffer and more trail friendly bike – the newest Sight Carbon, which Jill Kinter (above) has been riding to race wins in various iterations since around 2013. Starting with contemporary trail geometry updates to the 140mm travel frame, the new carbon bike also adds a completely new sibling by way of a 29er version.
The overhaul started out simple, but Norco’s engineers turned it into an opportunity to completely overhaul the Sight and its suspension to build two different wheelsize and travel bikes that both kept the same handling & ride feel character that made the Sight such a versatile trail bike. The result is the new Sight Carbon, available with either 27.5″ or 29″ wheels, but the same trail shredding good times no matter what wheel size you prefer…
The Sight Carbon carries over some tech from the past couple of generations of its carbon and alloy predecessors, but the key update is the new long, low & slack aggressive trail-riding geometry tailored for improved stability and more all-mountain fun. While the bike adds the new bigger wheelsize option to the trail bike platform, Norco says they went to great lengths to get the same ride feel, weight distribution, and handling characteristics out of both bikes.
Looking at the two wheel sizes next to each other, it is clear that is wasn’t as simple as stretching out the rear end to make room for bigger wheels. Now you can just pick the 27.5 bike if snappy acceleration is your deal or the 29er if you prefer the improved rollover.
To match the feel and performance of both bikes, the 29er was developed around the same rear center lengths as the smaller wheeled bike, with a longer front center, steeper headtube angles, a size stem, and 10mm less travel to offset the bigger wheels. In the end the stack and reach numbers of the bikes differ slightly, but come back to identical fits once you add their stems back in (to bar stack/reach vs. frame stack/reach).
