Mountain biking thrives on durability, performance, and value—and the Trifox MK7 Ultralight Aluminum Hardtail Frame delivers all three. Priced at an unbeatable $189, this 29er Boost frame is a steal for riders building or upgrading a trail-ready rig without breaking the bank.

Why Choose a 29er Boost Hardtail?

29-inch wheels roll over roots and rocks with ease, while Boost hub spacing (148mm rear) ensures stiffer wheels, better tire clearance, and compatibility with modern drivetrains. The MK7’s lightweight 6061 aluminum frame strikes a perfect balance between strength and agility, weighing just 1.8kg (size M). Its slack head tube angle (67.5°) and short chainstays (430mm) prioritize stability on descents and playfulness on climbs.

Features That Shine

The MK7 is built to handle rugged terrain. Key upgrades include:

- Internal Cable Routing: Clean looks and protection from mud/debris.

- Tapered Head Tube: Compatible with modern forks for precise steering.

- Universal Derailleur Hanger: Supports 1x or 2x setups.

- Thru-Axle Compatibility: Boosts stiffness and control.

Versatility Meets Affordability

Hardtails excel at efficiency and simplicity, making the MK7 ideal for cross-country, trail riding, or even bikepacking. Pair it with a 120-140mm fork, and you've got a budget-friendly beast ready for technical singletrack.



At $189, the Trifox MK7 is a rare blend of quality and affordability. Whether you're a beginner building your first MTB or a seasoned rider crafting a lightweight backup, this frame is a smart investment. Don’t miss this limited-time deal—explore the MK7 here and hit the trails with confidence!
