Both are excellent park bikes — that's the bullseye for both designs. The Norco Shore Park Boxxer comes ready out of the box: 200 mm dual-crown BoXXer, GX DH 7-speed, MaxxGrip DoubleDown rubber front and rear, and a coil-specific high-pivot rear that's been described as "buttery smooth."

The Slayer Alloy 30 Park matches the recipe — same 200 mm BoXXer, same GX DH drivetrain, DH-casing tires — but on a 29er frame with adjustable geometry. If you want maximum stability and 29" rollover, the Slayer Park edges it. If you want the more playful 27.5 feel, the Shore.

Neither is the wrong answer.

Yes, but neither is fast. Both weigh somewhere in the 37–38 lb range in their park trims, and both rely on coil shocks with no climb switch on the Shore (Norco intentionally omits one — a choice that drew criticism from NSMB).

The Shore has a steep 77.7° seat tube angle that keeps you balanced over the bottom bracket. The Slayer's RIDE-4 flip chip can steepen its seat angle to 77.8° in the climbing position, which MBA called "much more valuable for climbing than descending." Either way, plan on a slow grind. These are bikes you ride uphill to get back to the descent.

The Norco Shore is 27.5" only, in every size. Norco's bet is that smaller wheels are more playful in the air and easier to throw around — the classic freeride pitch.

The Slayer offers both. Sizes small and medium ship mullet (29 front / 27.5 rear); large and XL ship full 29". Aftermarket links let you flip any size to mullet. Pinkbike, Freehub, and others consistently note the mullet setup adds "pep" and makes the Slayer "less like a lumbering beast" in tight terrain.

If you ride mostly steep, technical, jumpy stuff and like the look of a 27.5 bike — Shore. If you want the option to plow on 29s and switch to mullet for park days — Slayer.

More than most bikes in the segment. The RIDE-4 flip chip in the rear linkage offers four positions, swinging the head angle from 62.5° to 63.3° and the seat tube angle from 77° to 77.8°, while also changing BB height and shock progression. A separate chainstay flip chip gives a 10 mm range (439 or 449 mm).

MBA called the geometry shift "more noticeable than most other flip chip systems." The Shore, by contrast, offers no geometry adjustment at all — what you see on the chart is what you ride.

It depends on the build. The Carbon 50 ($6,299) and Alloy 50 ($4,999) ship with the Fox 38 Performance fork and DHX2 Performance Elite shock. Pinkbike, MBA, and Enduro MTB all noted the stock tune sits deep in its travel and feels under-supportive — most aggressive riders ended up swapping the coil spring rate or upgrading the damper.

The Carbon 90 ($10,299) and Carbon 70 ($7,799) ship with Factory and Performance Elite GRIP2 setups that don't have this complaint. The Shore mostly avoids the discussion — it's coil-specific from the factory and reviewers haven't flagged the suspension tune as a major issue.

Both bikes have stock wheel concerns at their entry-level builds.

Shore: the ethirteen LG1 DH rims have a long-running reputation for denting and failing under hard riding — referred to in comments as "warm butter" or "cheese wheels." ethirteen has acknowledged early-production issues and updated the extrusion, but reports persist. The DT Swiss 350 hubs (on Shore 1, not on this Park build) are a solid foundation for an eventual rim swap.

Slayer (Carbon 50, Alloy 50): the WTB ST i30 alloy rims drew similar criticism, with Enduro MTB calling them "flimsy." The Alloy 30 Park moves to Race Face ARC HD 30 rims, which are noticeably tougher and don't draw the same complaints.

The Slayer's carbon models include a Penalty Box in-frame storage compartment under a magnetic hatch, big enough for a tube and tools — a nice touch on a freeride bike. Reviews are mixed on the latch (Freehub praised it, Enduro MTB lost theirs), but it's a real feature when it works. The alloy Slayers (including the Park edition) skip the Penalty Box.

The Shore has no in-frame storage but does ship with a downtube shuttle guard, a chainring bash guard, and bolts on the underside of the top tube for a tube/tool strap.

Both bikes get serious frame protection at the chainstay and downtube. Both use threaded bottom brackets — a small but appreciated detail for long-term maintenance.

Both brands offer a 5-year frame warranty on these generations. Rocky Mountain explicitly reinforced the Slayer's frame and pivots after a previous-generation failure, and Pinkbike noted the new design is "claimed to be stronger." Norco's warranty was historically 3 years on earlier Shore frames but moved to 5 years on the current generation, with the brand having proactively responded to early production issues on the 2021 model (replacing frames and updating manufacturing).

For a category of bike that's expected to take genuine abuse, both warranty terms are appropriate.
