Key Takeaway: The Salsa Cassidy is a 160/160mm aluminum enduro 29er built around Split-Pivot+ suspension — a capable, pedal-efficient platform that descends hard and climbs like a trail bike. At $1,099 for the brushed aluminum Large frame (down from $2,649, a 59% discount), it is one of the best frame-only deals in the enduro class right now.
Enduro bikes have to do two things at once: survive repeated shuttle laps and bike-park days, then pedal back up without beating you into the ground. Salsa's Cassidy has been one of the more thoughtful answers to that problem — a 29er aluminum chassis with modern geometry, a proven rear-suspension design, and the kind of tune-ability that keeps a frame relevant for three or four seasons of builds.
We have ridden a lot of aluminum enduro platforms. Here is what matters if you are weighing the Cassidy at this price point.
What the Cassidy Is
The Cassidy is Salsa's long-travel, 29-inch-wheel enduro frame. It runs 160mm of rear travel, is designed around a 160mm-stroke fork, and uses Salsa's Split-Pivot+ rear suspension — a derivative of the classic Dave Weagle Split-Pivot design that isolates braking forces from the suspension and produces a supple mid-stroke without giving up pedaling platform.
Key frame specs on the Large brushed-aluminum version:
- Material: Hydroformed 6066-T6 aluminum
- Wheel size: 29" front and rear (mullet-compatible with a compatible shock)
- Rear travel: 160mm
- Intended fork travel: 160mm (accepts 150–170mm)
- Head tube angle: 64° (slack enough for steep descending, not so slack it dies on climbs)
- Reach (Large): 480mm — modern without being extreme
- Bottom bracket: Threaded (no press-fit creak)
- Drivetrain: Boost 148 rear spacing, ISCG 05 tabs for a chain guide
A threaded bottom bracket and internal-but-clamped cable routing are unglamorous details that matter every time you swap a drivetrain or bleed brakes. Salsa got the maintenance story right.
Split-Pivot+ Suspension: Why It Matters
The Cassidy's rear end is the story. Split-Pivot+ places the driveside pivot concentric with the rear axle, which decouples braking from the suspension action. In practice, that means the rear wheel keeps tracking the ground under heavy braking into steep, chattery corners — exactly where less-refined designs skip, stiffen, and push you off-line.
On long climbs, the platform is more efficient than its 160mm of travel suggests. Pedal kickback is low, the mid-stroke sits high enough to keep the bike feeling lively, and you are not reaching for the shock lockout on fire-road climbs the way you do on some competitors.
This is not a magic bullet — a poorly tuned shock will still feel like a poorly tuned shock. But with a reasonable setup (a RockShox Super Deluxe, Fox DHX2, or EXT Storia all work well), the Cassidy rewards smooth, aggressive riders and forgives the occasional bad line.
Who Should Buy This Frame
The Cassidy at $1,099 makes the most sense for three kinds of rider:
- The frame-swap builder. You have a drivetrain, wheelset, fork, and cockpit you like, and you want a modern enduro chassis to wrap around them. Frame-only at 59% off lets you build a $5,000-equivalent bike for closer to $2,800.
- The second-bike rider. You have a trail or XC bike you love. You want a dedicated aggressive bike for bike-park laps, steep rides, and the occasional enduro race. An aluminum enduro platform is a smart second bike — durable, affordable to repair, and not precious.
- The upgrade-from-short-travel rider. You have outgrown a 130–140mm trail bike and want more travel without jumping to a full DH rig. Modern 160mm 29ers like the Cassidy are dramatically more capable than a similar bike from five years ago, and they still pedal well enough for long days.
If you ride mostly mellow trail, you do not need this much bike. A 130/140mm trail frame will be faster and more fun on flow trails. But on steep, rocky, technical terrain — or on laps at Whistler, Highland, Angel Fire, or any bike park — the Cassidy earns its travel.
Geometry in Context
At a 64° head tube angle and a 480mm reach on a Large, the Cassidy lands squarely in the modern enduro range. For comparison, recent aluminum enduro 29ers from Canyon, Commencal, and Norco sit within about a degree and 10mm of those numbers. Nothing about the Cassidy's geometry is extreme — which is exactly why it works for a wide range of riders and riding styles.
The 435mm chainstays keep the bike maneuverable in tight, technical corners. Seat tube angles run effective around 77°, which puts your hips over the bottom bracket on steep climbs and prevents the dreaded rearward weight shift that plagues older long-travel designs.
Build Considerations
A few notes if you are planning a build:
- Fork: 160mm air fork (Fox 36, RockShox Lyrik Ultimate, Öhlins RXF38 m.2). Do not undergun the fork — an underbuilt fork on a 160mm enduro frame is the single most common mistake in a home build.
- Shock: The Cassidy works well with most air shocks. If you weigh 200+ pounds or ride harsh terrain, consider a coil — the Split-Pivot+ rear end handles coils beautifully.
- Wheels: 30mm internal-width rims, DT Swiss 350 / Industry Nine Hydra / Chris King-class hubs. Enduro tires (Maxxis Assegai front, DHR II or Aggressor rear) in EXO+ or DoubleDown casing.
- Dropper: 170–200mm travel on a Large, depending on your inseam. Do not skimp here.
Is $1,099 a Good Price?
Aluminum enduro frame-only pricing from major brands typically sits between $1,800 and $2,600 at MSRP. The Cassidy's $2,649 retail is on the high end of that range — which is why the current $1,099 sale price is remarkable. That puts the Cassidy in the same price bracket as direct-to-consumer options from Commencal and Canyon, but with a domestic dealer network (Jenson USA) and the established Salsa warranty.
At 59% off, the math works even if you do not need the frame immediately. Aluminum frames do not go bad sitting in a basement. If you know a frame swap is coming in the next 18 months, locking in this price now is defensible.
What the Cassidy Is Not
A few honest caveats:
- It is not a lightweight climber. Aluminum enduro frames weigh what they weigh. Expect a built bike in the 33–35 pound range unless you spend serious money on components.
- It is not the latest geometry. If you want a 63° head angle, 510mm reach, high-pivot idler-pulley rear end, this is not that bike. It is a proven, reasonable enduro platform — not an experimental one.
- It is frame-only. You need a fork, shock, drivetrain, wheels, brakes, cockpit, and dropper to build it. Budget $2,500–$4,500 in parts, depending on your taste.
FAQ
Is the Cassidy compatible with a mullet setup?
Yes, with a compatible shock. Many riders run a 27.5" rear wheel and a 29" front for a slightly more playful feel. Check Salsa's geo chart for the effective changes to head angle and bottom bracket height before committing.
What size fork should I run?
160mm is the sweet spot. 150mm works if you want a slightly steeper, more trail-oriented feel. 170mm is the upper limit and will slacken the head angle into DH territory.
Does it come with a shock?
Frame-only. You will need to source a shock — 230x65mm metric trunnion mount.
How does it compare to carbon?
Stiffer in the rear triangle, slightly heavier, more durable in rock strikes, and dramatically cheaper. For aggressive park and enduro riding, aluminum's impact tolerance is an underrated virtue.
Bottom Line
At $1,099, the Salsa Cassidy is a legitimate enduro frame deal — not a closeout of an obsolete design, but a current-generation aluminum 29er with proven suspension and solid geometry. If you have been waiting for an excuse to build an aggressive 29er and you are comfortable sourcing parts, this is the excuse.
