Buying Guide: Key Considerations For 27.5 Full Suspension Frames
- Wheel compatibility: Most options are designed for 27.5″ wheels, but some also support 29ers. Confirm exact wheel size compatibility with your fork and tires.
- Rear axle standard: Common rear spacings include QR 135mm and thru-axle 12x148mm Boost. Choose according to frame compatibility and future upgrade plans.
- Travel and suspension: Travel ranges from around 160mm in downhill-oriented frames to lighter setups. Consider your terrain and preferred riding style when selecting travel length.
- Headset and bottom bracket: Ensure the frame supports the headset size and bottom bracket standard used by your components (e.g., 44/55mm headset, BC1.37x24T bottom brackets).
- Brake compatibility: Most frames support disc brakes. Check rotor size limits (often up to 2.4″ tires) and brake post mounting for your calipers.
- Weight and material: Aluminum frames offer a balance of weight and durability. If weight is critical, review the frame’s stated weight and pivot hardware construction.
- Shock specifications: Some frames ship with an integrated rear shock or require a compatible shock with matching eye-to-eye length. Verify shock compatibility and adjustability (rebound, compression, preload).
- Head tube and seat tube geometry: Consider head tube angle, reach, stack, and seat clamp compatibility to ensure a comfortable riding position for your height and terrain.
- Maintenance access: Pivot bearings and seals affect long-term durability. Look for frames with sealed bearings or serviceable pivots to ease maintenance.
- Assembly requirements: Building a full suspension frame often involves selecting a matching front triangle, fork, shock, and drivetrain components. Budget for a complete build beyond the frame.
