The Norco Sight, in most reviewer accounts. The high-pivot rear end with its rearward axle path lets the wheel get out of the way of square-edge hits, and the 28% progression curve — up from 18% on the prior generation — keeps the bike supportive deep in the travel. Reviewers describe it as carrying speed "like nothing else" through chunder and being "ultra stable, ultra capable" at speed.

The Stumpjumper is no slouch on the way down — the GENIE shock plus 145 mm of travel handles bike-park-sized hits without bottoming. But the Sight's combination of slacker head angle (64° vs 64.5°), longer wheelbase (1,219 mm vs 1,213 mm at the fit-picked sizes), and high-pivot kinematics gives it the edge when the trail gets genuinely rough.

The Specialized Stumpjumper, generally. It's lighter in carbon trim — the 15 Expert sits at 14.47 kg versus the Norco C1 at 15.9 kg — and the geometry is shorter and tighter, which makes switchbacks easier. The GENIE shock has a 2-position climb switch that firms the rear end on smoother climbs.

The Sight is surprisingly efficient for a high-pivot bike — Norco's idler design "nearly eliminates anti-squat," with anti-squat increasing in lower gears for less pedal bob. But reviewers consistently flag the Sight's "sheer length" (almost 1,250 mm wheelbase at S3) as "a bit of a handful" on tight technical climbs.

Both bikes ship in mixed-wheel (mullet) configurations at the editor's-pick tier — the Norco C1 150 MX runs 29" front / 27.5" rear, and the Stumpjumper 15 Expert at S3 runs the same setup.

Norco preserves geometry and kinematics across both wheel-size configs and offers full-29 builds for taller riders or 29er purists. The Stumpjumper auto-mullets the smaller sizes (S1–S2 in most builds) and runs full 29 from S3 up — though aftermarket links can convert any size to mullet.

Norco Sight Gen-5: 150 mm rear, 160 mm fork. Frame uses a 205x60 mm trunnion shock — air or coil compatible.

Specialized Stumpjumper 15: 145 mm rear, 150 mm fork (some builds run a 160 mm fork on the alloy coil models). Frame uses a 210x55 mm shock and is built around the proprietary Fox GENIE air spring, though standard 210x55 shocks will fit if you want to swap it out.

The Stumpjumper is the more adjustable of the two by a wide margin. Three headset cup positions move the head angle between 63°, 64.5°, and 65.5°. A chainstay flip chip lets you tweak BB height by roughly 7 mm. That's three head-angle positions and two BB heights stock.

The Sight has no headset adjustment and no flip chip — its geometry is fixed at 64° HTA. The adjustability you get is wheel size (29 or MX) and shock type (air or coil), both of which materially change the bike's character.

Specialized claims the GENIE uses mostly standard Fox internals — only one additional seal beyond a normal Fox Float — so most independent suspension shops can service it. Reviewers report it "worked without fault" through extended testing.

That said, there's legitimate skepticism in the comment sections about Specialized's history with proprietary suspension (Brain, Autosag) being orphaned over time. If you want maximum service flexibility, the Stumpjumper frame accepts standard 210x55 mm shocks — you can swap to a Fox Float X, RockShox Super Deluxe, or anything else in that size.

On the Sight, carbon (the C1, C2, C3) saves 1.5–2 kg over alloy (A1, A3) and unlocks the Eagle Transmission compatibility. The aluminum builds (A1 at $4,699, A3 at $2,799) are still well-specced — Norco uses RockShox Lyrik forks and quality wheels even on the entry models.

On the Stumpjumper, the carbon and alloy frames have meaningfully different drivetrain compatibility — only carbon supports the wireless-only routing for SRAM Transmission, while alloy retains mechanical cable routing and ships with Shimano SLX or Deore. Pinkbike has called the alloy frame "egregious" at 9.5 lbs (S4 frameset), but it's also the only path to mechanical shifting on this platform.

The Norco Sight, comfortably. Reviewers explicitly position it as leaning "more into the enduro side of the all-mountain spectrum," and the high-pivot suspension is genuinely race-derived — it shares a design language with the Norco Range and Aurum DH platforms.

The Stumpjumper is at its most aggressive in the EVO-style geometry positions (63° HTA, 160 mm fork), but it's still a 145 mm rear-travel trail bike at heart. For full-on enduro race stages, the Sight's longer wheelbase, slacker head angle, and high-pivot resilience win out.
