Product Details
The Santa Cruz Stigmata 4 Apex is a high-performance gravel bike built for riders who want to push boundaries, cover more ground, and discover new routes beyond the pavement. Combining race-ready speed with impressive off-road capability, the Stigmata delivers a versatile ride that feels equally at home on gravel race courses, remote backroads, and flowing singletrack trails.
Designed around Santa Cruz's advanced Carbon CC frame platform, the Stigmata strikes a balance between lightweight efficiency and confident handling. Its progressive geometry draws inspiration from the brand's mountain bike heritage, creating a ride that remains stable and predictable on rough terrain while still feeling quick and responsive when accelerating, climbing, or riding in a fast-moving group. The result is a gravel bike that encourages riders to take the scenic route, tackle challenging terrain, and explore farther than ever before.
For riders chasing podiums, the Stigmata offers the speed and efficiency needed to stay competitive in demanding gravel events. The lightweight carbon construction helps maximize power transfer while reducing fatigue over long distances. Generous tire clearance allows riders to run larger tires for increased comfort, traction, and control when conditions become rough or unpredictable.
Adventure-focused cyclists will also appreciate the Stigmata's ability to handle long days in the saddle and spontaneous overnight escapes. Whether it's a local gravel loop, an all-day backcountry adventure, or a destination gravel race, the bike is engineered to provide confidence and comfort mile after mile.
The SRAM Apex Eagle 12-speed drivetrain delivers a wide gear range suitable for steep climbs, high-speed descents, and everything in between. Paired with a dependable RaceFace AR Offset wheelset featuring DT Swiss 370 hubs, the Stigmata offers reliable performance and durability for riders who demand more from every ride.
Fast, capable, and endlessly adventurous, the Santa Cruz Stigmata 4 Apex is built for cyclists who believe the best routes are often the ones that are hardest to find.
