Got them today but the threads on on of the attachment brackets were so stripped out that I couldn’t thread into them so I couldn’t attach the right grip to the bike – really frustrating.

Customer Review: The bars came and the only thing semi damaged was the display box. The screw hex heads were somewhat damaged, but that is due to the soft metal profile uses, and cannot be seen once installed. Great price for an expensive option. The whole set was slightly more expensive than ordering just the pads separately.
Customer Review: Using for my bike setup on an indoor trainer, have not ridden outdoors. Like the angles and raised arm rests. Takes up a decent amount of space to mount on the handle bar, but I can also use the front of the drop handle bars still if I feel like it (due to raised rests).

Complete Buying Guide for Aero Bars
Essential Factors We Consider
When evaluating aero bars for mountain biking, we focus on several critical factors: compatibility with your existing handlebar diameter, ease of installation and removal, adjustability options, material quality, and overall value proposition. The best bars should enhance your riding experience without requiring extensive modifications to your current setup. We also consider weight, durability, and whether the bars accommodate brake lever integration if needed.
Budget Planning
Aero bars range dramatically in price from under $50 for basic aluminum models to over $300 for premium carbon fiber options. Entry-level bars ($50-$100) offer genuine aerodynamic benefits for casual riders, while mid-range models ($100-$200) provide professional-grade features at accessible prices. If you’re serious about performance, investing in carbon fiber bars ($200+) pays dividends through reduced weight and increased stiffness, though the returns diminish beyond certain thresholds.
Final Thoughts
Choosing the right aero bars for mountain biking depends entirely on your specific needs and riding style. Whether you’re a weekend warrior seeking faster times on fire roads or a competitive racer pushing limits, there’s a perfect solution among these top picks. Remember that proper fit trumps material choice—spend time adjusting reach and stack height until you find your sweet spot. Most importantly, choose bars that encourage you to ride longer and faster while staying comfortable throughout your adventure.
Frequently Asked Questions
Q: Can I install aero bars on any mountain bike?
A: While many aero bars are designed to fit standard road bike handlebars (typically 31.8mm diameter), compatibility varies by model. Always verify the specific measurements before purchasing. Some models offer wider clamp ranges or adapters for unconventional bar sizes. Additionally, consider whether your bike has sufficient clearance for the extended reach of aero bars, especially on bikes with suspension forks or crowded cockpit layouts.
Q: How do aero bars actually improve performance?
A: Aero bars reduce your frontal area exposed to wind resistance, which is the primary force slowing cyclists at higher speeds. By adopting a more streamlined position, you decrease drag coefficient significantly—often by 10-15% depending on your body shape and riding style. This translates directly to faster speeds for the same effort or reduced effort for maintaining target speeds, particularly beneficial during time trials, gran fondos, or sustained climbs on open roads.
Q: Are carbon fiber bars worth the extra cost?
A: Carbon fiber bars offer superior stiffness-to-weight ratios compared to aluminum, translating to more responsive handling and marginally better aerodynamics due to reduced flex. However, unless you’re competing professionally or riding extensively in variable wind conditions, the benefits may not justify the price difference for most recreational riders. Aluminum bars provide excellent performance at a fraction of the cost and are easier to repair if damaged.
Q: Do I need special brakes or levers to use aero bars?
A: Most modern aero bars include compatible brake lever shifters or can be adapted to work with existing hydraulic rim or disc brakes. However, some older brake systems may require additional adapters or replacement levers. When selecting bars, check whether they include brake-compatible hardware or if you’ll need to purchase additional components separately. Integration kits are available for various brake types if needed.
Q: How often should I adjust my aero bars?
A: Initial setup should be carefully planned based on your body proportions and riding goals. Once properly configured, avoid frequent adjustments as they can compromise structural integrity and alignment. Only adjust when changing riding disciplines, experiencing discomfort, or upgrading other components that affect your position. Periodic checks during seasonal maintenance ensure continued optimal performance and safety.
In conclusion, finding the best aero bars for mountain bike involves balancing your specific needs with available features and budget constraints. From the versatile Redshift Quick-Release bars that offer unmatched convenience to the premium carbon fiber options delivering race-winning performance, each model serves distinct purposes. Remember that proper fit and comfort should always take precedence over marginal aerodynamic gains. Take time to test different setups if possible, and don’t hesitate to invest in higher-quality components if you ride regularly—they’ll pay dividends through improved comfort, reduced fatigue, and ultimately, faster times across all terrains.
