Key Takeaway: The Salsa Cassidy is a 6061-T6 aluminum enduro frame designed for a 180mm fork and 165mm of Split Pivot+ rear travel — modern enduro geometry, flip-chip wheel-size adjustment, Super Boost spacing, and accessory mounts most pure-enduro frames don't bother with. At $1,099 (down from $2,649 — 59% off frame-only at Jenson USA), it's one of the best aluminum enduro deals on the market right now. Best for custom builders, aluminum loyalists, and bigger riders chasing composure on steep terrain.
The Salsa Cassidy has quietly become one of the most interesting aluminum enduro frames on the market — and right now it's available at $1,099, down from $2,649 (59% off). That's frame-only pricing that puts a modern, long-travel 29er platform within reach of riders who want to hand-pick their own build.

What the Cassidy Is Built For
Enduro. Full stop. With 180mm of travel up front and 165mm out back driven by Salsa's Split Pivot+ suspension, the Cassidy is aimed at riders who spend their weekends lapping chairlifts, shuttle roads, and the steepest black trails on their local mountain. It's not a trail bike pretending to be capable on the descents — it's a descent-first machine that still pedals back to the top thanks to Split Pivot's anti-squat-friendly kinematics.
Geometry: Modern Enduro, Done Right
Salsa went long, low, and slack with the Cassidy and didn't blink. A 63.8-degree head tube angle, a 75.7-degree seat tube angle, and a 481mm reach on the Large size put this squarely in 2026-era enduro territory. The rear flip chip lets you tune head angle and BB height for wheel size (29 or 27.5+) and terrain, so you can run it slacker for bike-park duty or firmer and snappier for pedally enduro laps.
Key Geometry Numbers (Size L)
- Reach: 481mm
- Stack: 631mm
- Head tube angle: 63.8°
- Seat tube angle: 75.7°
- Chainstay: 432mm
- Wheelbase: 1,262mm
- Standover: 741mm
Frame Details Worth Highlighting
- 6061-T6 aluminum construction — heavier than carbon but repairable and impact-tolerant. For an enduro bike that will see rocks, that's a feature, not a compromise.
- Split Pivot+ suspension — Dave Weagle's licensed platform, known for compliance under braking and supple mid-stroke. Paired with a RockShox Super Deluxe Select+ shock (230 × 62.5mm).
- Internal cable routing for a clean cockpit.
- Tire clearance up to 29 × 2.6" or 27.5 × 3.0" — room for mullets, plus-size rubber, or aggressive enduro casings.
- Accessory mounts on the top tube and down tube — rare on a modern enduro frame and a welcome nod to longer backcountry missions.
- 12 × 157mm Super Boost rear spacing for stiffness and tire clearance.
Who the Cassidy Is For
The Cassidy makes sense for three kinds of riders:
- The custom builder. Frame-only at $1,099 gives you a modern enduro platform to pair with parts you already own — or a chance to spec out a dream build for less than most complete enduro bikes.
- The aluminum loyalist. Riders who prefer the ride feel (and durability) of aluminum over carbon have fewer and fewer options at the top end. The Cassidy is one of the best remaining.
- The bigger, mountainous rider. Long reach, slack geometry, and Super Boost rear spacing all favor aggressive riders on aggressive terrain.
What to Watch Out For
This is a frame-only deal — you'll need a fork (180mm), drivetrain, wheels, brakes, cockpit, and seatpost. A complete build on top of this frame realistically runs $2,500–$4,000 depending on how deep you go on components. If you're not comfortable sourcing parts or paying a shop to build it, a complete enduro bike may be a better fit.
Also note: at 6061-T6 aluminum with the included air shock, this is not a lightweight frame. The Cassidy rewards riders who prioritize composure and confidence over gram-counting. The shock spec is air-only — coil shocks are not compatible with the Cassidy's leverage curve.
How It Compares
At current pricing, the Cassidy sits alongside aluminum frames from Commencal, Canyon (when available frame-only), and Santa Cruz's Heckler alloy lineup. Against those, the Cassidy stands out for its Split Pivot suspension licensed from Dave Weagle, the flip-chip geometry, and the accessory mounts that hint at longer-day usability most pure enduro frames ignore. Against carbon enduro frames from Specialized, Yeti, and Santa Cruz at $3,500–$5,000+, the Cassidy at $1,099 is in another universe price-wise — and the ride feel difference is far smaller than the price gap suggests.
The Verdict
At retail ($2,649), the Salsa Cassidy is a solid modern enduro frame. At $1,099, it's one of the best frame-only deals going right now for riders who want a 180/165mm 29er platform with modern geometry and a respected suspension design. If you've been waiting for a reason to build up a dedicated enduro rig, this is it.

Frequently Asked Questions
What fork should I run with the Salsa Cassidy frame?
Salsa designed the Cassidy around a 180mm-travel fork with 42–51mm offset. The RockShox Lyrik Ultimate or ZEB, Fox 38, and Marzocchi Bomber Z1 in 180mm all match the geometry. Running a shorter fork (170mm) is acceptable but slackens the seat tube and steepens the head angle compared to spec; longer than 180mm pushes the head angle into territory where the bike feels lazy on flat trails.
Will Boost 148mm wheels work on the Cassidy?
No. The Cassidy uses Super Boost 157mm rear spacing for added stiffness and tire clearance. If you have a Boost 148mm wheelset, you'll need a new rear hub or a complete rear wheel. DT Swiss, Industry Nine, We Are One, and most enduro-grade wheel brands offer 157mm Super Boost options off the shelf.
Can I run a coil shock on the Cassidy?
No. The Cassidy's leverage curve is tuned for an air shock, and Salsa does not certify coil compatibility. Stick with the included RockShox Super Deluxe Select+ or another 230 × 62.5mm air shock with a similar tune.
How much will a complete Cassidy build realistically cost?
$2,500–$4,000 on top of the $1,099 frame, depending on parts choices. A budget-conscious build using value-oriented brands (Marzocchi Bomber Z1, SRAM NX/GX drivetrain, Stan's wheels, OneUp dropper, TRP brakes) lands closer to $2,500. A premium build (Fox 38 Factory, SRAM XX1 AXS, We Are One wheels, OneUp V3 dropper, SRAM Code RSC brakes) easily clears $4,500. Most riders building on a Cassidy aim for the $3,000–$3,500 range.
Is the Cassidy a one-bike quiver for trail and enduro?
It can be, but it's optimized for descending. The Cassidy will climb fine on Split Pivot's anti-squat tune, but every climb feels a bit slower than a 140–150mm trail bike. If your riding is mostly trail with occasional bike-park days, a shorter-travel frame is a better all-around match. If your riding is mostly aggressive trail and descents with the occasional pedal-back climb, the Cassidy is the right tool.
