Best MTB Trail Tires 2026: Front & Rear Pairings
Best MTB Rear Shocks for 2026: Air vs. Coil
Two seasons ago I swapped the air shock on my enduro bike for a coil. Did it because a friend told me it would “change everything.” He was half right. Small-bump sensitivity got noticeably better on the chattery rock gardens I ride every week. But I also gained over 300 grams, lost meaningful climbing efficiency on long fire road approaches, and spent the first month fiddling with spring rates because the stock spring was too light for my weight. Nobody told me about that part.
That experience is why I wanted to write this. The site covers forks in depth (the Fox 36 SL, the Flight Attendant vs. Live Valve comparison) but rear shocks have been a blind spot. And the 2026 rear shock market is genuinely interesting right now, partly because of what’s here and partly because of what’s coming.
Fox announced the 2027 Float X and DHX updates in March 2026—Pinkbike, Flow MTB, and Vital MTB all ran first looks. That means the current-generation Float X2 Factory and DHX2 Factory are showing up at reduced prices as shops clear inventory. If you’ve been eyeing either shock, the next few months are the window. Meanwhile, RockShox dropped the Vivid Coil with Adjustable Bottom Out and gave the Deluxe Ultimate lighter compression tunes. Both are meaningful updates. Not just color swaps.

Air vs. Coil: What’s the Actual Difference?
This question dominates every rear shock thread on every forum, and most answers overcomplicate it. Here’s the short version:
Air shocks use a sealed air chamber as the spring. Lighter (350-500g typical), tunable with a shock pump, and progressively ramping, meaning they resist more as they compress deeper into the stroke. That progressive ramp helps prevent bottom-out on big hits without needing excessive damping. Most trail and enduro bikes ship with air shocks because they’re lighter and adaptable to different rider weights without changing hardware.
Coil shocks use a metal spring. Heavier (600-900g once you add the spring), more linear through the stroke (meaning consistent resistance from top to bottom) and better at absorbing small, repeated bumps. That linearity is why coil fans talk about “bottomless feel” and “sensitivity.” The shock doesn’t ramp up and push back like an air spring does. It just absorbs. The trade-off: you need the correct spring rate for your weight, and changing it means buying a new spring (~$40-70).
When Does Coil Actually Make Sense?
- Your terrain is sustained chunk—rocky, rooty, high-frequency hits where small-bump sensitivity matters more than weight savings
- You ride enduro or DH where descending is the priority and climbing efficiency is secondary
- Your bike’s frame has a leverage ratio that works with coil (progressive suspension designs pair well with linear coil springs)
- You don’t mind the weight penalty and you’re not counting grams for long XC-style climbs
When Does Air Win?
- You climb as much as you descend and weight matters
- You want one shock that adjusts to different conditions with a pump instead of a spring swap
- Your bike’s leverage ratio is already progressive enough that the air spring’s ramping doesn’t create a harsh ride
- You’re building a budget trail build where versatility beats specialization
Most trail riders—like, 70% of the people reading this—should be on air. It’s lighter, more adjustable, and good enough for the descending that trail bikes are built for. Coil makes sense for the specific scenarios above. Don’t let internet consensus talk you into adding a pound to your bike because someone in a forum said it feels better. It might. It might also wreck your climbing.
Best Air Shock Overall: Fox Float X2 Factory
Price: ~$600 (discounted from ~$720 as 2027 models approach) | Weight: ~430g | Damper: Four-way adjustable monotube | Adjustment: HSC, LSC, HSR, LSR | Sizes: 185x55 to 250x75
The Float X2 Factory is what you get when Fox throws everything at a rear shock. Four-way adjustable damping (high-speed and low-speed for both compression and rebound) with an ultra-low-friction monotube design that tracks better on small bumps than any air shock I’ve ridden. That’s not hyperbole. The improvement in initial sensitivity compared to the standard Float X or older DPX2 is something you feel in the first thirty seconds on trail.
I ran the Float X2 on a 160mm enduro bike through a full winter of frozen chunk and loose-over-hardpack on the Front Range. Mid-stroke support is where it earns its money. On long, rough descents with braking bumps and square-edged rocks, the X2 holds its position in the travel without packing down or wallowing. I could run slightly less sag (28% vs my usual 30%) and still get good small-bump pickup because the damper is that sensitive.
Four-way adjustability sounds intimidating, but you can set it and mostly forget it. I run 2 clicks of HSC from closed, 8 clicks of LSC from closed, and rebound tuned to the one-bounce-back method from our suspension setup guide. Haven’t changed it in two months.
The 2027 Float X has been announced but isn’t shipping yet. Shops are clearing Float X2 Factory inventory at $100-120 below MSRP. If you find one in your size, that’s a genuine deal on a shock that’s still one of the best air options available.
Best for: Enduro and aggressive trail riders who want maximum tuning control and best-in-segment sensitivity from an air platform. Riders swapping from a basic air shock who want a clear step up without going coil.
Skip if: You ride mellow trails where a simpler two-way shock does the job. Four-way adjustability is wasted on buffed singletrack. The RockShox Deluxe Ultimate at $380 makes more sense for trail-focused riders.
Best Air Shock for Trail: RockShox Deluxe Ultimate (2026)
Price: ~$380 | Weight: ~350g | Damper: DebonAir+ air spring, two-position compression | Adjustment: LSC, rebound | Sizes: 165x45 to 230x65
The 2026 Deluxe Ultimate got quieter updates than the Vivid, but they matter. RockShox reworked the compression tune and bottom-out system to deliver a more supple, open feel at trail speeds. Translation: it tracks better on chattery terrain without requiring you to run the compression wide open, which used to leave the older version feeling unsupported in the mid-stroke.
At 350g, the Deluxe Ultimate is the lightest shock in this roundup. For trail bikes in the 120-140mm range where pedaling efficiency and weight savings count, that’s the right tool. I wouldn’t call it a replacement for the Float X2 on a long-travel enduro bike—it doesn’t have the same mid-stroke composure on sustained chunk. But on a trail bike doing what trail bikes do—climbing for an hour, descending for twenty minutes, climbing again—the Deluxe Ultimate’s lighter weight and simpler two-knob interface make more sense than a four-way damper you’ll never fully exploit.
The DebonAir+ air spring is a meaningful improvement over the standard DebonAir. Bigger negative chamber volume improves breakaway sensitivity—the shock’s willingness to move on the smallest hits right at the top of the stroke. That’s the spec that translates directly to traction on small roots and rocks where the wheel needs to follow terrain instead of bouncing off it.
Best for: Trail riders on 120-150mm bikes who prioritize climbing weight and simplicity. Riders who want a reliable, lightweight shock and don’t need four-way adjustability. The best option under $400.
Skip if: Your riding leans enduro or you want the most refined damping available. The Float X2 is a tier above in composure and tuning range.
Best Coil Shock: RockShox Vivid Coil (2026)
Price: ~$450 (shock body, spring sold separately ~$50-70) | Weight: ~680g + spring (total ~900-950g depending on rate) | Damper: Adjustable Bottom Out (ABO) with five compression settings | Adjustment: ABO, LSC, HSC, rebound | Sizes: 205x60 to 250x75
The 2026 Vivid Coil is the most interesting shock in this roundup—and the one I’ve been testing most aggressively. RockShox introduced Adjustable Bottom Out (ABO) with five compression settings, and it’s the first coil shock I’ve used with meaningful mid-stroke tuning that doesn’t require swapping to a custom-wound spring or fiddling with a hydraulic bottom-out bumper.
Here’s what ABO does in practice: it changes how the shock transitions from the mid-stroke to the bottom of the travel. At setting 1 (lightest), the shock runs deep into travel freely—great for high-speed chunk where you want every millimeter of stroke. At setting 5 (firmest), there’s a noticeable ramp in the last 25% of travel that prevents bottom-out on drops and g-outs without making the shock feel harsh through the rest of the stroke. I’ve been running it at 3 for general enduro riding and dialing it to 5 for bike park days. The adjustment takes five seconds with an Allen key.
The small-bump compliance on this shock is the best argument for coil. Period. On repeated square-edged hits—the kind where air shocks build pressure in the chamber and start feeling harsh—the Vivid’s coil spring stays linear and absorptive. Root sections that I’d fight through on my Float X2 (even at open compression settings) just disappear under the Vivid. The rear wheel tracks terrain instead of skipping across it.
The weight penalty is real though. My size shock with the right spring rate (450 lb/in for my 175-pound riding weight) weighed 940g on the scale. That’s 510g heavier than the Float X2. You feel it on climbs. A twenty-minute fire road approach costs you some effort, and steep technical climbs where the rear needs to stay light feel marginally worse. It’s a trade-off, and pretending it isn’t is dishonest.
Best for: Enduro and DH riders on 150mm+ bikes who ride rough terrain with sustained chunk. Riders frustrated with air shock harshness on repeated hits. Anyone who’s been coil-curious and wants the most tunable coil shock currently available.
Skip if: You value climbing performance and light weight. You ride trail bikes under 140mm where the weight penalty negatively affects the bike’s intended use. Or your terrain is smooth enough that an air shock’s sensitivity is adequate.
Best Coil Shock for DH / Enduro: Fox DHX2 Factory
Price: ~$550 (deals appearing as 2027 announced, spring separate ~$50-70) | Weight: ~650g + spring | Damper: Pressure-balanced twin-tube | Adjustment: HSC, LSC, HSR, LSR | Sizes: 205x60 to 267x89
The DHX2 Factory is Fox’s coil flagship, and the pressure-balanced twin-tube design gives it a durability advantage over single-tube competitors. Where single-tube shocks can develop cavitation and fade on long, hot DH runs, the DHX2’s twin-tube layout maintains consistent damping as oil temperature rises. That matters for bike park laps and race runs where you’re hitting the shock hard, repeatedly, for minutes at a time.
Four-way adjustability on a coil shock gives you the tuning range to dial in ride feel precisely. I ran the DHX2 on a DH bike for shuttle days and found the HSC adjustment more useful than on any air shock—coil springs don’t have an inherent progressive ramp, so the high-speed compression circuit is doing more of the bottom-out management work. Getting that right (I settled on 4 clicks from closed) made the difference between blowing through travel on big drops and using the full stroke with control.
Like the Float X2, the 2027 DHX has been announced but isn’t on shelves. The current DHX2 Factory is appearing at discounted prices. If DH or heavy enduro is your riding and you prefer coil, this is a strong time to buy.
Compared to the Vivid Coil, the DHX2 lacks the ABO feature—you manage bottom-out through spring rate and high-speed compression tuning, which works but isn’t as intuitive as RockShox’s five-position dial. The DHX2’s advantage is damper durability under sustained abuse and a slightly more composed feel on high-speed square-edge hits where the pressure-balanced circuit keeps the damper tracking.
Best for: DH riders and shuttle-focused enduro riders who push shocks hard enough to care about thermal fade. Riders who want four-way coil tuning. Fox loyalists who run Float X2 up front and want a matched coil platform in the rear.
Skip if: You want the tuning simplicity of the Vivid’s ABO system. Or you’re a trail-focused rider—coil shocks on trail bikes rarely make sense, and the DHX2 is the heaviest option here.
What We Tested But Didn’t Recommend
EXT Storia: Exceptional shock at an extraordinary price (~$900+). The hydraulic bottom-out adjustment is more refined than anything here. But the price excludes 90% of riders, and availability remains limited. If money isn’t a constraint, seek one out. For everyone else, the Vivid Coil’s ABO gets you 80% of the benefit at half the price.
Cane Creek DBcoil IL: Good coil shock, but the air-assisted coil design adds complexity without a clear advantage over a pure coil like the Vivid or DHX2. The twin-tube damper works well, but at ~$500 it sits in an awkward middle ground between the Vivid’s ABO innovation and the DHX2’s durability edge.
MRP Hazzard: Solid budget coil option (~$300) but the damper lacks the refinement of the top-tier options. On high-speed chunk, it fades noticeably compared to the DHX2. If budget is tight and you want coil, wait for Vivid or DHX2 clearance deals.
Setup Basics: Getting Your Rear Shock Right
Air Shock Setup
- Set sag to 28-32% of total shock stroke. Measure with an O-ring, riding weight, in attack position. Our suspension setup guide walks through the full process.
- Set rebound so the shock returns quickly enough to track terrain but doesn’t bounce you off the saddle. The classic test: push the saddle hard, release—the bike should return to sag position in one smooth motion without oscillating.
- Low-speed compression controls pedal bob and body movement. Start in the middle of the range and adjust by feel.
- Volume spacers (air shocks only): add spacers to increase end-stroke ramp and prevent bottom-out. Remove spacers for a more linear, plush feel. One spacer at a time, ride, assess.
Coil Shock Setup
- Get the right spring rate. This is non-negotiable and the step most people mess up. Most manufacturers publish spring rate calculators based on rider weight and bike leverage ratio. Use them. A spring that’s too soft bottoms out constantly. Too firm and you lose small-bump sensitivity—the whole reason you went coil.
- Set sag to 28-33% with the correct spring installed.
- Tune rebound and compression the same way you would an air shock. Coil shocks respond to damping changes more noticeably because the spring rate is fixed—you’re adjusting the oil circuit without the variable of air pressure influencing the feel.

The Bottom Line
The air vs. coil debate doesn’t have a universal winner, and anyone telling you otherwise is selling something (or just finished installing a coil and needs to justify the purchase—I’ve been that person).
Air shocks are lighter, more adjustable, and the right call for most trail riding. The Float X2 Factory is the best of them, and the incoming 2027 models make this a smart time to buy the current generation at a discount. The Deluxe Ultimate is the move for trail bikes where weight and simplicity beat tuning range.
Coil shocks trade weight for sensitivity, and the 2026 Vivid Coil finally makes that trade-off more nuanced with ABO. Five compression settings that change mid-to-bottom-stroke behavior without swapping springs? That’s a real innovation on a platform that hadn’t changed meaningfully in years. The DHX2 remains the durability king for riders who punish equipment.
My advice: ride what your bike came with for a full season. Learn what your shock does well and where it falls short on your terrain, at your speed, with your riding style. Then upgrade with a specific problem to solve. “I bottom out on the rock garden at mile six” is a solvable problem. “I want my bike to feel better” is a recipe for spending $500 and ending up in the same place.
Your terrain dictates your shock. Not the internet.
