In the world of gravel cycling, where adventure meets performance, having the right equipment can make all the difference. If you’re looking to elevate your ride on rough terrains, the URS MTT Kit stands out as a game-changer. Designed specifically for BMC’s UnReStricted (URS) series, this innovative component enhances compliance and comfort without sacrificing speed or efficiency. Whether you’re a seasoned gravel grinder or just dipping your toes into off-road exploration, understanding the URS MTT Kit can help you unlock new levels of enjoyment on your bike.
Gravel biking has exploded in popularity over the past decade, blending the speed of road cycling with the ruggedness of mountain biking. Brands like BMC have been at the forefront, pushing boundaries with technologies that cater to this hybrid discipline. The URS MTT Kit, part of BMC’s Micro Travel Technology (MTT) system, is a prime example of this innovation. In this comprehensive guide, we’ll dive deep into what makes this kit special, its features, benefits, and how it fits into the broader ecosystem of gravel bike accessories.
To fully appreciate the URS MTT Kit, it’s essential to look at the history of the BMC URS lineup. Launched in 2019, the URS series was BMC’s bold entry into the gravel market, standing for “UnReStricted.” These bikes were engineered for versatility, capable of handling everything from smooth pavement to chunky trails. The initial models featured a unique rear suspension system that provided subtle compliance, setting them apart from rigid gravel frames.
Fast forward to recent updates, and the URS has seen significant enhancements. According to cycling experts, the latest iterations boast increased tire clearance up to 47mm, longer chainstays for better stability, and a slacker head tube angle for improved handling on technical descents. This evolution emphasizes adventure-ready geometry, making the bike ideal for bikepacking and long-haul rides.
At the heart of these improvements is the MTT system, which the URS MTT Kit supports. MTT, or Micro Travel Technology, introduces up to 20mm of rear travel using an elastomer-based damper. This isn’t full-suspension like a mountain bike; instead, it’s a subtle “micro” system that absorbs vibrations and impacts, reducing fatigue on extended rides. The kit itself is a replacement or upgrade part, ensuring your URS bike maintains optimal performance over time.
The URS MTT Kit is more than just a spare part; it’s a precision-engineered component that integrates seamlessly with the URS frame. Here’s a breakdown of its standout features:
These features make the URS MTT Kit a must-have for anyone serious about optimizing their gravel bike’s performance.
Understanding the mechanics behind the URS MTT Kit can help you appreciate its ingenuity. The MTT system is integrated into the frame’s seat stays, positioned behind the seat tube and below the top tube. When you hit a bump, the elastomer compresses, allowing controlled flex in the rear triangle. This 20mm of travel is damped to prevent rebound harshness, resulting in a smoother ride.
For higher-end URS models, the system extends to the front. The URS 01 uses an MTT stem for added compliance, while the URS LT features a full MTT fork with matching 20mm travel. The kit itself replaces or tunes the rear elastomer, ensuring consistent performance. Riders can choose from soft, medium, or firm shims to match their preferences—lighter riders might opt for softer settings for better sensitivity, while heavier ones go firmer for support.
This setup not only enhances comfort but also improves traction. On loose gravel or uneven surfaces, the suspension keeps the wheels planted, boosting confidence and control. It’s a far cry from traditional rigid frames, offering a bridge to mountain bike-like capabilities in a gravel package.
Investing in the URS MTT Kit brings tangible benefits that can transform your cycling experience. First and foremost, it reduces rider fatigue. Long gravel rides often involve hours of vibrations that can lead to discomfort in the hands, back, and legs. The MTT system’s damping mitigates this, allowing you to ride farther and faster.
Additionally, it enhances versatility. With features like cargo attachments on the seat tube and downtube storage compartments, the URS bike (bolstered by the kit) is perfect for bikepacking adventures. Imagine loading up for a multi-day trip without worrying about rough paths—the suspension handles the abuse while you focus on the scenery.
Performance-wise, the kit maintains the bike’s agility. Unlike heavier full-suspension setups, the micro travel doesn’t sap pedaling power, making it suitable for competitive gravel events. Users report better handling on descents and improved speed on mixed terrains, thanks to the slacker geometry and increased clearance.
From a practical standpoint, the kit is affordable at around $139, making it an accessible upgrade. It’s also easy to source from BMC dealers or online retailers, with low stock often indicating high demand.
Installing the URS MTT Kit is relatively straightforward for those with basic mechanical skills, but we recommend consulting a professional if you’re unsure. Start by removing the old elastomer from the seat stay junction. Clean the area thoroughly, then insert the new kit components, securing them with the provided hardware. Adjust the shims based on your weight—BMC provides guidelines for optimal setup.
Maintenance is key to longevity. Inspect the elastomer regularly for cracks or wear, especially after muddy rides. Clean it with mild soap and water, avoiding harsh chemicals. If you notice reduced compliance, a shim swap or full kit replacement might be needed. With proper care, the URS MTT Kit can last thousands of miles, keeping your bike feeling fresh.
For advanced users, pairing the kit with compatible accessories like dropper posts (via a 27.2mm shim) can further customize your ride.
How does the URS MTT Kit stack up against competitors? Systems like Cannondale’s Kingpin or Specialized’s Future Shock offer similar compliance, but BMC’s approach is unique in its tunability and integration. The Kingpin uses frame flex without dampers, which can feel less controlled, while Future Shock focuses on front-end isolation.
The MTT’s elastomer design provides progressive damping, which many riders prefer for its predictability. In reviews, the URS system scores high for maintaining a “road-like” feel on pavement while excelling off-road. If you’re comparing kits, consider your riding style—MTT shines for adventure-oriented gravel.
Cyclists who’ve upgraded with the URS MTT Kit often rave about its impact. One rider shared on a popular forum that it “transformed my URS into a beast for technical gravel,” noting reduced arm pump on long descents. Another appreciated the tunability, saying it allowed fine-tuning for different terrains.
Common praises include durability and ease of adjustment, though some mention the need for occasional cleaning in wet conditions. Overall, satisfaction is high, with many recommending it as an essential spare for URS owners.
The URS MTT Kit embodies BMC’s commitment to innovation in gravel cycling. By providing tunable, lightweight suspension, it bridges the gap between comfort and performance, making it ideal for explorers and racers alike. If you’re ready to take your URS bike to the next level, this kit is a worthwhile investment. Check with your local dealer for availability and start planning your next unrestricted adventure today.
Remember, the right gear like the URS MTT Kit isn’t just about specs—it’s about enhancing the joy of riding. Happy trails!
