Norco Sight A1 150 MX Bike 2025Sight for Sore Eyes If your riding style takes you down steep loam lines and deep into the backcountry, the Norco Sight A1 is a top all-mountain bike contender. The aluminum frame pairs 150mm of rear travel with a plush 160mm suspension fork. This setup provides plenty of cushion to soak up the trail when it gets rough. This MX version runs a 29" wheel up front and a 27. 5" wheel in back. A 64deg head angle keeps the bike planted on fast and steep chutes. Seat tube angles of 77deg to 78deg put you over the pedals when the climbs get steep. Chainstays from 420mm to 436mm, to keep the bike balanced across all frame-sizes. This build features a directly mounted, wireless SRAM GX Eagle AXS T-Type 12-speed drivetrain. A robust 32T chainring and a massive 10-52T cassette give you ultra-low gears for steep, technical climbs. To keep your chain running smoothly when the trail gets choppy, the frame uses both an idler guide and a lower guide. Stopping power comes from ultra-powerful SRAM Maven Silver brakes. They pair a 200 mm front rotor with a 180 mm rear rotor maximum control on long descents. The wheelset features durable DT Swiss 350 hubs laced to Stan's Flow S2 tubeless-ready rims. For maximum grip on loose rock, they come wrapped in a Maxxis Assegai tire up front and a Minion DHR II tire in the back. A reliable Tranz X dropper post gets your saddle out of the way the second you drop into a line. The bike includes a One Up EDC Lite tool for quick trailside adjustments. Top-tier suspension comes from a Rock Shox Lyrik Ultimate fork with the Charger 3. 1 damper and a Vivid 2 Ultimate rear shock to meet your exact tuning needs.
