It depends on the trails. The Ibis HD6's 29/27.5 mullet setup makes the bike noticeably easier to flick into corners and lift the rear over obstacles — reviewers consistently describe it as 'agile and playful' for a 165 mm bike, and the smaller rear wheel keeps the seat out of your gut on steep drops.

The Yeti SB160's full 29er setup carries momentum better through rough terrain and rolls over square-edge hits with less hang-up. If most of your riding is fast and chunky, the 29er pays off; if it's tight, technical, or features lots of body-English moves, the mullet wins.

Both climb exceptionally well for 160-plus-mm bikes — but reviewers give the HD6 the edge. Its DW-Link suspension is described as 'one of the best-pedaling enduro bikes I've ever ridden,' with 'unimaginably snappy' acceleration thanks to high anti-squat. The HD6 also weighs ~32–33 lb in mid-tier trim vs ~34–35 lb for a comparable SB160.

The SB160 is no slouch — the 77.5° seat tube angle (steeper than the HD6's 76–77.5°) puts you in an excellent climbing position and the Switch Infinity system delivers a 'peppy, urgent sensation' under power. It's one of the best-pedaling 29er enduro bikes, just not quite as effortless as the HD6 over a long day.

The HD6's DW-Link is described as 'buttery off the top,' transitioning into firm mid-stroke support and a progressive end-stroke that resists harsh bottom-outs. It feels traction-focused and forgiving — easier to ride well at moderate speeds.

The SB160's Switch Infinity V2 runs a more linear 17% progression curve. Reviewers call it 'supportive rather than plush' — it stays high in its travel, communicates the trail back to you ('information overload, in a positive sense'), and rewards aggressive input. It's less forgiving of passive riding but more composed when you're charging.

Yes, and this matters. The HD6 runs a fixed 435 mm chainstay across all sizes (S–XL). Riders on the smaller sizes love the agility; reviewers note this can feel rear-biased for taller riders on the L (508 mm reach) and XL (541 mm reach), where the front wheel can wash if you're not actively weighting it.

The SB160 uses size-specific chainstays from 437 mm (S) to 445 mm (XXL), growing roughly 2 mm per size. The result is consistent front-rear balance regardless of frame size — taller riders aren't fighting a rear-biased chassis. It's one of the SB160's standout engineering details.

Significantly. Ibis spec's Fox Factory 38 forks and Float X2 Factory shocks on every HD6 build, including the $4,999 Deore. That's Kashima coating, the full GRIP X2 damper, top-tier sealing — the same dampers you'd otherwise buy aftermarket for ~$2,500.

Yeti reserves Fox Factory dampers for the Turq-series builds (T1 and up, $8,900+). The C-series builds ($6,400 / $6,900) get Fox Performance 38 forks and Performance Float X shocks — same architecture, different damper internals and no Kashima. Yeti offers an $800 Factory upgrade on C-series builds. If you're buying at the $6–7k tier, the HD6 is the cheaper way to get top-tier damping.

Ibis HD6: dedicated mullet, 29 in front and 27.5 in rear only — no flip chip to convert to full 29er. Stock tires are Maxxis Assegai 2.5 front and Minion DHR 2.4 rear. Frame clearance accommodates this comfortably.

Yeti SB160: dedicated 29er front and rear, no mullet conversion. Current builds ship with Schwalbe Magic Mary front / Albert rear in 2.5 in widths.

Both come with lifetime frame warranties to the original owner.

Ibis uses sealed lifetime bushings (not bearings) at the lower link — a deliberate simplification that long-term reviewers report works well in practice ('clean, little layer of grease, assemble 1x/yr'). Ibis covers the lower link bushings under lifetime replacement and includes a 7-year impact warranty on their carbon rims.

Yeti's Switch Infinity V2 link (on Turq-series only — C-series gets the older V1 hardware) is also under lifetime warranty. Pivot bearings are pressed into aluminum links rather than the carbon frame, which makes bearing service less risky to the frame. Service interval on the SI translating pivot is 40–75 hours depending on conditions.

Often, yes — and it's the most consistent critique in SB160 reviews. At the $8,500–$10,800 range, the SB160 frequently pairs higher-end derailleurs (X0 / XX) with cheaper GX cassettes and chains, and the T3 X0 AXS at $10,800 still ships on alloy DT Swiss EX1700 wheels. At the same price tiers, the HD6 builds tend to be more internally consistent.

That said, the SB160 frame's engineering refinements (threaded BB, bolt-on cable clamps, alloy-housed pivots, Switch Infinity V2) are part of where the price goes — and Yeti's lifetime warranty on the SI link is unique. Whether that justifies the spec gap depends on how much you value the frame vs the parts.
