Its 12x148mm boost thru-axle ensures stiffness and precise handling on steep, technical sections. The 6061 aluminum alloy construction provides a balanced weight and durability, while fully sealed bearing pivots offer minimal maintenance and better water/dust resistance. A tapered head tube and 31.6mm seat tube diameter align with modern cockpit standards for improved control on aggressive descents.
Key specifications and compatibility include a 44/56x110mm tapered head tube, 73mm threaded bottom bracket, and room for up to 3.0” tires. The frame aims to deliver confident handling at high speeds, with robust pivot systems designed to keep the drivetrain aligned under heavy loading. As a versatile platform, it’s well-suited to riders who alternate between enduro routes and longer trail days.
Canyon Spectral 5
The Spectral 5 is positioned as an all-rounder capable of technical descents and long rides alike. Its lightweight aluminum frame provides a responsive feel, while progressive geometry offers stability on steeps and agility on tight, technical sections. The bike ships with a RockShox suspension setup featuring 150mm front and 150mm rear travel, paired with a RockShox 35 Silver fork and Deluxe Select shock. This configuration balances supple bump absorption with control, ensuring confident handling on evolving trail conditions.
Designed to tackle a wide range of terrain, the Spectral 5 emphasizes a balance between stiffness and compliance. Its geometry supports aggressive riding without sacrificing pedaling efficiency on flatter sections. The setup favors riders who want a single bike capable of both long climbs and spirited descents, minimizing the need for frequent frame changes while maintaining reliability on rugged courses.
Gravity FSX 29″ Aluminum Dual Suspension Frame
The Gravity FSX frame emphasizes durability and ease of maintenance. With disc brake mounts and a replaceable derailleur hanger, it’s built to withstand tough riding conditions and minor mishaps common on steep trails. The frame comes with an adjustable rear shock, enabling riders to tune the setup for varying terrain, whether they’re hammering a long descent or navigating a windy forest singletrack. This frame is well-suited for riders who want a reliable, modular platform with straightforward serviceability.
Frame geometry focuses on stability at speed, while the 12x148mm boost through-axle remains a common standard for modern suspension platforms. The combination makes it a practical choice for riders who value compatibility with a wide range of components, tires, and suspension configurations. If you’re building a robust enduro bike or a capable all-terrain machine, this frame provides a solid foundation.
Full Suspension 27.5″/29er DH/XC/AM Frame
This full-suspension frame is built to deliver downhill confidence with a broad wheel compatibility range. It supports 27.5″ and 29″ wheels and offers a 160mm downhill rear travel with a 60mm air travel shock, designed for aggressive riding and heavy impacts. The frame uses a 12x148mm boost thru-axle and has internal routing options to keep wires tidy and protected. Aimed at DH/XC/AM riders who want a single frame system capable of absorbing big hits while maintaining pedaling efficiency on climbs, it provides a balanced approach to performance across varied terrains.
The 6061 aluminum alloy construction contributes to a robust yet serviceable platform. With fully sealed bearing pivots and a reverse-capable geometry, this frame is built to handle frequent trail abuse while maintaining predictable handling. The 3.0″ tire allowance widens the wheel options for increased traction on loose surfaces, mud, and roots, making it a practical choice for muddy or rocky courses and long marathon-style events.
Full Suspension Enduro/Downhill Carbon Frame
This carbon fiber frame is designed for enduro and downhill disciplines with 120mm travel and a 12x148mm boost thru-axle. The carbon construction offers high strength-to-weight ratio, increased stiffness, and improved impact absorption, contributing to precise handling on rough descents. The frame can accommodate tire widths up to 27.5×3.0″ or 29×2.35″, enabling riders to tailor traction and rollover performance to the trail conditions. Internal routing for cables and hoses helps maintain a clean build with reduced snag potential on fast sections.
The Enduro/Downhill frame also emphasizes a robust internal design with a 52x52mm internal routing headset and a T47 threaded bottom bracket. Ride feel centers on confidence during extreme descents and variable terrain while keeping the overall weight manageable. It’s suited for riders who demand high-end performance and are comfortable with carbon frame maintenance requirements in exchange for enhanced stiffness and efficiency on challenging trails.
Buying Guide: Key Purchase Considerations
- Frame material: Aluminum offers a good balance of price, durability, and weight. Carbon fiber provides high stiffness and lightness but at a higher cost and more meticulous maintenance.
- Travel and geometry: Downhill and enduro riders typically prefer longer travel (140–160mm front and rear) and progressive geometries for stability at high speeds and on steep descents.
- Wheel compatibility: Ensure compatibility with your preferred wheel sizes (27.5″ vs 29″) and consider 12x148mm Boost thru-axles for stiffness and alignment.
- Suspension integration: Frames that support internal routing, sealed pivots, and adjustable rear shocks enable cleaner builds and easier maintenance.
- Tire clearance: Check max tire width to ensure compatibility with your chosen rubber for desired traction on mud, roots, and loose surfaces.
- Serviceability: Frames with replaceable derailleur hangers and straightforward pivot maintenance reduce downtime on long days in rough terrain.
- Intended use: Decide between all-day trail versatility or dedicated downhill capability to match frame travel, stiffness, and durability with your riding goals.
- Component compatibility: Verify headset, Bottom Bracket, seatpost diameter, and clamp compatibility with your cockpit and drivetrain setup.
- Weight vs. strength: Carbon frames are stiffer and lighter but costlier; aluminum frames offer durability and easier repairs in field conditions.
When selecting a downhill or Enduro frame, consider how you ride most of the time, including trail conditions, climb/pedal effort, and the type of terrain you encounter. A frame that balances stiffness, travel, and tire clearance will deliver consistent performance across varied courses, while ease of maintenance and service support will reduce downtime on longer trips. Always confirm fit with your preferred fork, shock, and wheel sizes to ensure optimal handling and control on aggressive trails.
