The Cassidy C Frameset is the foundation of your big-travel bike dreams. Whether you want a bike for occasional park days or you’re a full-on enduro racer, this is the ticket. Our carbon enduro bike frame comes with a Fox Float X2 Factory shock with 165 mm of travel — pair it with a 180 mm fork for a stable ride over unpredictable terrain and features. Cassidy’s geometry and Split Pivot suspension design are a recipe for a planted ride through gnarly root beds, wicked rock gardens and an air of confidence when you’re airing it out. On-bike storage features include a padded tube strap spot, a top tube mount, and full-size bottle capacity to take your rides further. The groundwork is laid — build it up your way.

Additional Features

Split Pivot Rear Suspension

Split Pivot provides a host of impressive suspension characteristics because the system isolates pedaling forces and braking forces from each other, allowing us to tune and optimize the bike for both independently. The concentric rear axle pivot, in conjunction with precise wheel link, brake link, and control link placement, results in excellent bump compliance and pedaling efficiency, smooth and predictable braking throughout travel, and maximum traction

Split Pivot+ Design Methodology

The Split Pivot+ design methodology allows our engineers to optimize a frame for more than one travel class. This means that Cassidy riders can swap control and shock links, in addition to the rear shock and fork, to switch travel to Blackthorn’s 140 mm rear and 160 mm front capability. One frame, multiple bikes

Progressive Leverage Rate

Progressive from start to finish, Cassidy’s leverage rate is tuned for speed. It delivers supple small-bump action early for a smooth ride at high speed; a consistent and supportive feel through the mid-stroke for popping, pumping, and holding up to high-G corners; and continued progression through the end-stroke to provide plenty of support for big hits and recovering from poor line choices

Flip Chip 2.0

Integrated into the shock link mount, Flip Chip 2.0 allows simple, quick adjustments to bottom bracket height and head tube angle to account for the rider’s personal preference, terrain, or wheel size and tire diameter

EPS Carbon Main Triangle with Carbon Seatstays and Aluminum Chainstays

EPS construction allows for greater manufacturing control, smooth surfacing, a simplified bottom bracket junction, and an integrated shock mount. Carbon fiber material offers improved stiffness, better vibration damping, excellent toughness and weight savings compared to other materials. 6066-T6 aluminum heat-treated chainstays add durability

Top Tube Accessory Mounts

Top tube mounts accommodate K-Edge Top Tube Mount for bike computers or the Salsa EXP Series Direct Mount Top Tube Bag

Down Tube Three-Pack Mounts

Three-Pack mounts on down tube accommodate a large water bottle on the lower pair and a frame-mounted pump bracket on the upper pair

Integrated Repair Kit Location

Located in front of the rear shock in the front triangle, we provide a dedicated place for a small repair kit, tube, or bag of gummies. No more loading up your pockets or strapping the essentials to random spots on the frame and damaging the frame finish. Carbon frames feature an integrated reinforced slot and frame protection. Aluminum frames feature a machined strap slot. The slot is sized to accommodate most ¾"- to 1"-wide straps. A Salsa Tube Strap is included with each frame (the Salsa Tube Strap is for use with tubes only)

Accommodates a 26 oz Bottle

Located in front of the rear shock in the front triangle, we provide a dedicated place for a small repair kit, tube, or bag of gummies. No more loading up your pockets or strapping the essentials to random spots on the frame and damaging the frame finish. Carbon frames feature an integrated reinforced slot and frame protection. Aluminum frames feature a machined strap slot. The slot is sized to accommodate most ¾"- to 1"-wide straps. A Salsa Tube Strap is included with each frame (the Salsa Tube Strap is for use with tubes only)

Internal Sleeved Cable Routing

Internal tubes guide housing through the frame, simplifying setup and maintenance, and creating a clean bike profile

Stealth Dropper Post Routing

Compatible with 30.9mm dropper posts for true trail bike performance

Molded Frame Protection

Molded rubber down tube, seat tube, chainstay, and seatstay guards protect your frame from impacts and abrasion

Versatile Tire Fit

Spec’d with a 29 x 2.5" tire up front and a 29 x 2.4" in the rear, Cassidy is also capable of running up to 29 x 2.6" or 27.5 x 2.8-3.0" wheels and tires

Chain Guide-Compatible

Cassidy frames features ISCG-05 mounts for chain guides (removable on carbon frames)

Remote Lockout Ready

Cassidy C comes equipped for remote lockout, with cable routing to the rear shock via a guided port on the drive side of the downtube that exits under the forward shock mount.

FAQ

How do I convert my Cassidy to a Blackthorn?

Can I run a coil shock?

No, the leverage rate of the Cassidy is optimized for the natural progressivity of air spring shocks. A coil shock will not produce enough end-stroke support at the rear wheel, leading to frequent and harsh bottom-outs that will likely result in frame damage. Fitting a coil shock to this frame voids the warranty.

Can I run a mullet setup on this bike?

Yes, for Cassidy mullet setup requirements:

  • Minimum fork travel: 180 mm; minimum fork axle to crown: 596 mm
  • Minimum front tire size: 29 x 2.4"
  • Minimum rear size: 27.5 x 2.5"
  • Maximum crank arm length: 170 mm
  • Flip chip position must be set to high

Do you offer touch-up paint?

No, we do not offer touch up paint. Hobby shops or automotive stores are excellent places to find paint. We suggest you test the paint on a scrap piece of metal before using it on your frame.

I crashed and dented (or cracked) my frame. Is it safe to ride?

Stop riding your frame immediately and take it to the nearest Salsa authorized dealer for inspection. A dented or cracked tube represents a structural weakening of the frame, and is a safety risk.
