Norco OpticvsSight

Norco has taken a massive gamble by porting high-pivot (VPSHP) technology down from their downhill bikes into these two platforms. While the Optic sits in the trail category with 125mm of rear travel and the Sight occupies the all-mountain space with 150mm, they are cut from the same cloth. Both use an idler pulley to manage the chain growth inherent in their rearward axle paths, effectively 'slicing' square-edge bumps so the rear wheel doesn't hang up on rocks or roots. This isn't just about travel numbers; it is about how that travel is delivered. The Optic targets the 'downcountry-plus' rider who wants a sharp, reactive pedaling platform but expects to survive double-black descents. The Sight is a different animal, leaning toward the enduro end of the spectrum where stability at speed and traction in the loose are the only things that matter. While the Optic is lighter and arguably more versatile for rolling terrain, the Sight is built for riders who treat every descent like a race stage.

The Optic is the shortest-travel high-pivot bike on the market, and it rides with a strange, addictive dual personality. On fast, chattery singletrack, it delivers a 'feels-like-it-as-more-travel' sensation that masks its 125mm rear end, yet it retains a poppy nature that allows you to loft it over trail features with zero effort. However, the rearward axle path—growing 7mm to 10mm under load—means the wheelbase lengthens just as you're loading the bike into a corner. Some testers found this 'disconcerting' in G-out situations, as the handlebars feel like they're moving away from you mid-turn. The Sight handles with the absolute stability of a miniature downhill bike. It tracks over rocks with a 'deathly quiet' composure that makes it feel much more stuck to the ground than the Optic. Where the Optic invites you to play and pop, the Sight eggs you on to brake later and plow into the rough. Its 150mm of travel feels virtually bottomless thanks to a steep 28% progression rate, which is a massive jump from the previous generation's 18%. This makes it a formidable platform for coil shocks, which are frequently spec'd to maximize that 'glued-to-the-trail' feel. Climbing is surprisingly efficient on both, provided you keep the idler clean. The anti-squat is tuned to increase in the easier gears, so the bikes don't wallow when you're winching up a 20% grade. The Optic is the clearer choice for technical, punchy climbs where you need to 'mash' the pedals to clear a ledge. The Sight is more of a 'sit-and-spin' tractor; it’s heavy—often hitting 37 pounds in aluminum builds—but it finds traction on greasy roots where other bikes would simply spin out.
