Crankbrothers Synthesis Alloy 2.0 Enduro MTB Rim with Lifetime Warranty

The Crankbrothers Synthesis Alloy 2.0 Enduro Rim represents a significant advancement in mountain bike wheel technology, combining innovative materials with precise engineering to elevate your riding experience. Designed specifically for enduro riders who demand durability and performance, these rims are crafted from the superior 6069 alloy, offering enhanced strength and longevity compared to previous models. With a shot-peened finish, the rims resist wear and fatigue, ensuring they can withstand the rigors of aggressive trail riding and challenging terrain.

Each rim features a re-engineered profile that balances impact resistance and compliance, tailored distinctly for front and rear applications. The front rim prioritizes traction and shock absorption, while the rear rim delivers the stiffness and strength necessary for power transfer and control. This thoughtful design reduces pinch flats and enhances overall wheel reliability, making the Synthesis Alloy 2.0 a trusted choice for riders seeking consistent lap-after-lap performance. Additionally, the lifetime warranty offered by Crankbrothers underlines their confidence in the durability and quality of these rims.

What It’s Good For

• Enduro and aggressive trail riding where durability and impact resistance are critical
• Riders seeking a reliable wheelset with enhanced strength and fatigue resistance
• Front and rear wheel applications requiring specific tuning for traction and stiffness
• Reducing the risk of pinch flats thanks to engineered rim profiles and material placement
• Long-term investment supported by a lifetime warranty covering manufacturing defects and crash damage

What It’s NOT Good For

• Usage outside of mountain biking or enduro disciplines
• Riders who do not require the enhanced durability and strength features of the alloy 6069
• Applications where wheels are subjected to extreme misuse beyond normal riding crashes
• Those seeking lightweight wheels optimized solely for cross-country racing or less aggressive riding
• Situations involving improper assembly, maintenance, or unauthorized repairs that void warranty coverage

Frequently Asked Questions

What makes the 6069 alloy better than previous alloys?
The 6069 alloy used in the Synthesis Alloy 2.0 rims offers significantly improved strength and durability, with enhanced tensile and fatigue properties. This means the rims are more resistant to cracking and wear, providing longer-lasting performance under demanding conditions.

How does the shot-peened finish benefit the rims?
The shot-peened finish increases the fatigue life of the rim, improves resistance to cracking, and enhances wear resistance. It also provides a refined look compared to the previous brushed finish, making the rims both stronger and more visually appealing.

Are the front and rear rims the same?
No, the front and rear rims have different internal widths and profiles. The front rim is designed for compliance and traction, while the rear rim is built for added stiffness and strength to support power transfer and control.

What does the lifetime warranty cover?
The lifetime warranty covers manufacturing defects, damage caused by crashes during normal riding, dents or flat spots where the tire can no longer hold air, and seam separation or cracks at the spoke hole area. It does not cover normal wear, improper assembly, maintenance issues, or damage from misuse.

Can I use these rims with any tire size?
The Synthesis Alloy 2.0 rims have an inner width of 28.5mm, making them compatible with a wide range of MTB tires, especially those suited for enduro and trail riding. Always check tire manufacturer recommendations for compatibility.
