BUCKLOS 140mm Travel Front Fork
Traveled at 140 mm, this BUCKLOS fork is designed for versatile terrain—from rocky climbs to loose descents. Built with 34 mm aluminum-magnesium upper tubes to enhance rigidity, it maintains consistent steering feedback through 20-click external rebound adjustment. The crown lockout helps optimize trail response on climbs, while a 9 mm x 100 mm QR allows quick wheel changes. It uses a threadless straight steerer and supports disc brakes for reliable stopping power. Specifications include a 28.6 mm threadless steerer, crown race of 30.0 mm, and a weight around 1976 g, offering a balance of stiffness and damping for aggressive XC/AM riding.
Key considerations:
- Compatibility with 1-1/8″ straight or tapered configurations
- Rebound control and crown lockout for tailored feel
- Max tire clearance around 3.0 inches

Buying Guide: Front Fork Upgrades For Mountain Bikes
- Travel and terrain compatibility: Choose travel that matches your typical riding conditions. Longer travel (120–140 mm) suits aggressive trail/AM; shorter travel (100 mm) favors XC efficiency.
- Lockout and damping: External or remote lockouts help on climbs; rebound adjustment and compression damping tailor the feel for weight and terrain. Ensure dampers are serviceable and available locally.
- Steerer and axle compatibility: Confirm your frame uses a straight 1-1/8″ or tapered steerer and your fork’s QR width (9×100 mm is common). Check axle standards and brake compatibility (disc brakes recommended).
- Weight considerations: Lighter forks improve responsiveness but may compromise stiffness; heavier forks often offer robust damping with easier setup for heavier riders.
- Material and rigidity: Aluminum-magnesium alloy forks can balance weight and strength. Consider tube diameter (around 32–34 mm) for improved steering precision.
- Maintenance and serviceability: Look for forks with readily available seals, air springs, and rebuild kits. Field-replaceable parts are a plus for long rides.
- Compatibility with tires: Ensure tire clearance supports up to your widest tire; many forks accommodate up to ~3.0 inches.
- Brand and warranty: Reputable brands with clear warranty terms help with long-term satisfaction and repairs.
