BSFHQS 27.5/29er Enduro Frame
The BSFHQS 27.5/29er Enduro Frame is designed for DH and AM riding with a soft-tail feel. It supports 12×148 Boost thru-axle setups and accommodates tires up to 27.5×2.8″ or 29×2.5″, offering compatibility with wide forks and rear shocks. The frame features both internal and external alignment methods for a reliable drivetrain alignment. A PM 75mm disc brake interface accepts a 180mm rotor, with a 203mm adapter required for larger brakes. It accepts 31.6mm seatposts and a 34.9mm clamp, plus 44/55mm tapered headsets. BSA BB73mm threaded bottom brackets provide robust longevity. The geometry supports 160mm/170mm fork travel and 150mm/172mm rear wheel travel. The ISCG-05 chain guide compatibility and 30/32/34T chainring allowances expand setup options.
HIMALO 27.5er/29er Full Suspension Frame
This frame supports both 27.5 and 29er wheels and is aimed at DH/XC/AM riding styles. It uses 12×148 Boost thru-axle geometry and accepts up to a 3.0″ tire width. The 6061 aluminum construction provides a balance of stiffness and lightness, with fully sealed pivot bearings to improve resistance to water and dust. The design accommodates rear travel up to 160mm, and its air rear shock provides a versatile range of dampening for rough terrain. It’s compatible with 160mm travel forks for a proven downhill performance profile.
YFGSFWTS 27.5er/29er Softtail Frame
The YFGSFWTS Softtail frame is built for downhill and AM use with a preference for 27.5/29ers. It weighs around 3750g (about 8.3 lbs) and uses 44-55mm headset compatibility, a 30.9mm seatpost, and 34.9mm seatpost clamp. The frame supports 210mm eye-to-eye shock absorber travel, with a rear wheel travel of about 155mm and a fork travel compatibility around 160mm. The setup includes a hard-chromed damper shaft and coil spring damping arrangement. This frame is designed to accommodate AM, FR, and DH riding styles with a versatile geometry and shock configuration.
Gravity FSX Aluminum Full Dual Suspension
The Gravity FSX frame offers full dual suspension with an aluminum build geared toward general dual-suspension setups. It includes replaceable rear derailleur hanger and an adjustable rear shock, providing a straightforward option for riders who want a dependable, all-purpose frame. The disc brake mounts ensure reliable stopping power, and the frame is designed for compatibility with common drivetrain and braking standards. This option is suitable for riders seeking a versatile frame for mixed DH/XC/AM terrain without specialized travel numbers.
HIMALO 27.5er/29er 148mm Frame
This HIMALO frame supports 27.5 and 29er wheel configurations with 148mm Boost through-axle. It is compatible with 3.0″ tires and employs a fully sealed bearing pivot system to improve water and dust resistance. The frame features a tapered head tube (44/56mm), a 31.6mm seat tube, and a BC1.37x24T threaded bottom bracket. It is designed for DH/XC/AM riding and includes disc brake compatibility, providing a balanced option for riders who want a robust, all-around frame for gravity-oriented trails.
Buying Guide
Key purchase considerations include axle standards, tire clearance, and shock compatibility. When selecting a frame, verify compatibility with your preferred rear shock length (for example, 210mm eye-to-eye or 205x65mm), and confirm the bottom bracket and headset sizes to ensure proper fit with your crankset and fork. Consider head tube angle and wheel travel to match your terrain, whether it’s steep, technical DH trails or fast cross-country sections. Through-axle width (12×148) improves wheel stiffness and precision but requires compatible hubs and frame spacers. Material choice (6061 aluminum vs. other alloys) balances weight, stiffness, and durability. Finally, ensure the frame supports your tire width goals and the braking system you plan to use (disc brake compatibility with rotor size in mind).
For a well-rounded setup, look for frames with: robust ISCG-05 chain guide compatibility, a reliable seatpost diameter (commonly 30.9–31.6mm), and clear documentation on shock compatibility, travel ranges, and headset bearings. If you ride aggressively, prioritize frames designed for 160–170mm fork travel and rear travel in the 150–170mm range. If you value a lighter build for climbing, consider frames that emphasize a lower weight while preserving stiffness. Lastly, check for warranty coverage and the availability of spare parts and replacement components to extend the frame’s lifespan.
