Buying Guide
Key considerations when choosing a downhill fork include travel, stiffness, and compatibility with your bike and tires. If you ride extreme descents or big drops, prioritize longer travel (140–180 mm or more) and a robust crown/arch to minimize flex. Thru-axle front ends (e.g., 15×110 mm) provide greater steering precision on rough terrain, but ensure your frame supports the bolt pattern and spacing. Damping options matter: external rebound adjustments let you tailor feel to your weight and riding style, while crown lockouts improve efficiency on climbs. Consider weight, material quality (aluminum vs magnesium alloys), and service availability for future maintenance.
- Travel range: 120–203 mm; choose based on terrain and bike category
- Steerer type and axle compatibility with your frame
- Adjustments: rebound, lockout, air pressure; maintenance needs
- Material and weight: balance durability with efficiency
- Wheel/tire clearance: ensure tires fit under the crown and arches
