Terrel
The Propain Terrel CF marks the German mountain bike brand’s first entry into the gravel category. Introduced in 2024, this carbon platform is built around high versatility and off-road capability rather than pure racing speed. Propain designed the Terrel to bridge the gap between traditional drop-bar bikes and hardtail mountain bikes, making it well-suited for bikepacking, technical trail exploration, and aggressive adventure riding.
The frame utilizes a carbon construction engineered for durability and compliance, featuring integrated downtube storage, robust frame protection, and extensive mounting points for cargo. Recognizing its gravity-oriented audience, Propain built the Terrel with suspension-corrected geometry, allowing riders to swap the stock rigid carbon fork for a short-travel suspension option. The platform also embraces modern, easily serviceable standards, including a threaded T47 bottom bracket and a Universal Derailleur Hanger.

| Seat tube length | 545mm |
Fit and geometry
The Terrel CF’s geometry is heavily influenced by modern mountain bike design, prioritizing stability and descending prowess. Across the size range, the frame features a slack 70.5-degree head tube angle on a size medium, paired with a long 1,062mm wheelbase and 435mm chainstays. This long and slack footprint keeps the bike composed at high speeds and prevents the steering from feeling nervous on steep, loose terrain.
To accommodate the option of a suspension fork without ruining the bike's handling, Propain utilizes a suspension-corrected design. The frame pairs a relatively short head tube with a longer rigid carbon fork, keeping the stack height comparable to traditional gravel bikes while maintaining the correct front-end height.
Rider posture is sporty but centered, aided by a steep 73.5-degree seat tube angle that positions the rider efficiently over the bottom bracket for seated climbing. The handling character is highly dependent on cockpit setup. Some builds feature wide, 46cm handlebars with a slight rise, which maximizes leverage on technical trails but can feel exposed to headwinds on long, flat road sections.
Builds
Propain offers the Terrel CF through a direct-to-consumer model, with a build ladder that emphasizes reliable, off-road-ready components over ultra-lightweight racing parts. The lineup highlights the bike's versatility, offering both traditional gravel drivetrains and mountain bike mullet configurations.
The Signature Spec 1 serves as the entry point, featuring a SRAM Apex mechanical drivetrain and a standard rigid Zipp seatpost. Stepping up to the Signature Spec 2 introduces electronic shifting via a SRAM Apex and GX T-Type AXS mullet drivetrain, pairing drop-bar shifters with a wide-range mountain bike rear derailleur and cassette for tackling steep, loaded climbs. This premium build also adds a RockShox Reverb AXS XPLR dropper post, further expanding the bike's capability on technical descents.
Both builds share a practical, durable foundation. They roll on DT Swiss G 1800 Spline aluminum wheelsets wrapped in high-volume 50mm Schwalbe G-One Overland tires, a combination that prioritizes traction and puncture protection over rotational weight savings. Both models also utilize a Selle Italia Model X Superflow saddle and rely on the frame's standard T47 bottom bracket and UDH compatibility for straightforward long-term maintenance.
Reviews
Reviewers consistently characterize the Terrel CF as a highly capable off-road machine that trades outright speed for stability and control. On technical singletrack and steep descents, the bike excels, with testers noting it occupies a "sweet spot between a gravel drop bar bike and a hardtail mountain bike" (YouTube). While it maintains momentum well on flat terrain, acceleration is generally described as "solid but not explosive" (Granfondo), a trait attributed to the robust frame construction and the rotational weight of the stock aluminum wheelsets.
The ride quality presents a distinct front-to-rear split. The rear triangle and 27.2mm seatpost provide noticeable compliance, effectively muting vibrations on long stretches of rough gravel. Conversely, the front end is notably stiff. The stout rigid carbon fork delivers precise steering but transmits a significant amount of "energy coming through the handlebars" (YouTube) on bumpy terrain. This leads some testers to suggest that a suspension fork is a logical upgrade for riders frequenting sustained, rocky descents.
Despite the firm front end, the bike remains a "playful companion" (Granfondo) in tight corners. Reviewers praise the frame's overall durability and rattle-free downtube storage, though one tester noted a potential issue with water retention in the frame compartment after riding in intense rain. Overall, the consensus points to a highly adaptable platform that thrives when pushed beyond smooth dirt roads.
