2021 Sight Aluminum Frame 2021

Sight A Frame

By re-imagining how we design bikes, our engineering department shattered the status quo with the Ride Aligned™ design system, addressing how a rider’s centre of gravity impacts the bike’s performance and then built the Sight A’s All-Mountain design and aluminum frame around that.

The Sight A Frame Kit offers 150mm of travel in both 29 and 27.5-inch wheel options to suit every rider’s preference and is designed around a 160mm travel fork so you can build your aluminum All-Mountain dream ride.
