Nukeproof Mega Carbon 297 MX Kit
Convert your Mega 290 Carbon V4 into the ultimate mixed-wheel enduro machine with the Nukeproof Mega Carbon 297 MX Conversion Kit.
Designed to transform your 29er Mega into a modern mullet setup, this kit allows you to run a 29-inch front wheel and 27.5-inch rear wheel, combining the confidence and rollover capability of a larger front wheel with the agility and responsiveness of a smaller rear wheel.
The result is a bike that offers outstanding front-end grip, improved cornering confidence and increased manoeuvrability on steep, technical terrain.
The Mega has earned its place as one of the most successful enduro bikes ever produced, claiming multiple Enduro World Series titles and countless industry awards. Developed alongside elite athletes and passionate riders, the Mega platform continues to evolve, and the 297 MX configuration represents the latest step in that progression.
Why Choose a Mixed-Wheel Setup?
A mixed-wheel (mullet) setup combines the best characteristics of both wheel sizes:
- Improved front-wheel grip and stability from the 29-inch front wheel
- Enhanced rollover performance on rough terrain
- Increased agility and responsiveness from the 27.5-inch rear wheel
- Greater clearance behind the saddle on steep descents
- Easier direction changes through tight corners and technical sections
Whether you're racing enduro or pushing your limits on demanding trails, the 297 MX setup delivers a balanced ride that's fast, capable and confidence-inspiring.

Frequently Asked Questions
Will this change the geometry of my Mega?
No. The Mega platform was designed with interchangeable configurations in mind, allowing different wheel formats while maintaining the intended geometry and ride characteristics.
Can I install this kit myself?
Installation is suitable for experienced home mechanics with the correct tools and knowledge. As with any full-suspension frame, correct assembly procedures, torque settings, lubrication and thread preparation are essential. If you are unsure, installation by a qualified bicycle mechanic is recommended. Check the guide here
Is a rear wheel included?
No. A Boost 148mm 27.5-inch rear wheel and tyre must be sourced separately.
Who is this kit ideal for?
Riders looking to gain the benefits of a mullet setup without replacing their existing Mega frame. It's particularly popular with aggressive trail, enduro and bike park riders who value manoeuvrability on steep and technical terrain.
