If you’re a BMC bike owner looking to optimize your ride, the ICS2 MTT Hardware – Bumpers Black stands out as a key component for enhancing your setup. This replacement kit is designed specifically for the ICS2 MTT stem, offering cyclists the ability to fine-tune their suspension system with ease. Whether you’re a gravel enthusiast or a road rider seeking smoother journeys, understanding this hardware can transform your biking experience.
In this comprehensive guide, we’ll dive deep into what makes the ICS2 MTT Hardware – Bumpers Black essential, its features, compatibility, installation tips, and more. By the end, you’ll have all the information needed to decide if this upgrade is right for you.
Understanding ICS2 MTT Technology: The Foundation of Advanced Bike Suspension
Before we explore the ICS2 MTT Hardware – Bumpers Black in detail, it’s important to grasp the technology behind it. BMC’s Micro Travel Technology (MTT) represents a breakthrough in integrated suspension for bicycles. Developed in collaboration with Redshift, this system incorporates elastomers into the stem to provide up to 20mm of tunable travel, absorbing vibrations from uneven surfaces without compromising the bike’s overall stiffness or aerodynamics.
The ICS2 MTT stem, part of BMC’s Integrated Cockpit System (ICS), blends sleek design with functional compliance. It pivots around an oversized axle, maintaining lateral stiffness comparable to traditional stems while allowing vertical flex to reduce muscle fatigue. This technology is particularly beneficial for riders on models like the URS AL or Roadmachine X, where low tire pressure and frame compliance alone might not suffice for ultimate comfort.
MTT isn’t just about adding suspension—it’s about efficiency. By smoothing out road imperfections, it enhances control, speed, and endurance. Riders report feeling less battered after long rides, making it ideal for endurance cycling, gravel adventures, or even daily commutes on pothole-ridden streets.

As shown in the image above, the ICS2 MTT stem comes with a set of colorful elastomers, which are the core of the suspension tuning. These are where the ICS2 MTT Hardware – Bumpers Black comes into play as a replacement or customization option.
Key Features of ICS2 MTT Hardware – Bumpers Black
The ICS2 MTT Hardware – Bumpers Black is a genuine BMC replacement part, specifically an elastomer system kit for the ICS2 MTT stem. Priced at around USD 39, it’s an affordable way to maintain or upgrade your bike’s performance. Here’s a breakdown of its standout features:
- Variety of Hardness Levels: The kit includes elastomers in five different colors—yellow, blue, red, black, and green—each representing a unique durometer (hardness). Yellow is the softest (around 60 durometer), providing maximum compliance for lightweight riders or those preferring a plush feel. As you move to orange, blue, green, and black (up to 90 durometer), the stiffness increases, suiting heavier riders or those wanting more responsive handling. This allows for personalized tuning based on rider weight, style, and terrain.
- Complete Replacement Set: What’s in the box? You’ll get one of each elastomer bumper, a rebound elastomer, a preload wedge, a preload bolt (M5x18), a screw, and two plastic parts. This comprehensive package ensures you have everything needed for a full overhaul or adjustment.
- Durability and Quality: Made from high-quality elastomers, these bumpers are built to withstand repeated compression and rebound. They’re designed for longevity, resisting wear from vibrations and environmental factors like dust or moisture.
- Seamless Integration: Compatible exclusively with the ICS2 MTT stem, the hardware maintains the stem’s internal cable routing and aerodynamic profile. No need for major modifications—it’s a plug-and-play solution.

In terms of specifications, the SKU is 30002038, and it’s tailored for models like the MY22 URS01, Roadmachine X, and 257 AMP. BMC emphasizes that this kit elevates the riding experience by reducing fatigue and improving control on rough terrains.
Compatibility: Which Bikes Benefit from ICS2 MTT Hardware – Bumpers Black?
Not every bike is suited for the ICS2 MTT Hardware – Bumpers Black, but if you own a compatible BMC model, it’s a game-changer. Primarily designed for the ICS2 MTT stem, this kit works seamlessly with:
- MY22 URS01: A gravel bike known for its versatility on mixed terrains.
- Roadmachine X: An endurance road bike that excels in long-distance comfort.
- 257 AMP: Urban and adventure-oriented models that benefit from added compliance.
To confirm compatibility, check your stem model. The ICS2 MTT stem is available in lengths from 80mm to 140mm, and the bumpers are universal within this range. If your bike features BMC’s ICS technology, you’re likely good to go.
For non-BMC bikes, alternatives like Redshift’s standalone ShockStop stems exist, but they lack the integrated routing of the ICS2 system. Always consult BMC’s spare parts list or a local dealer for precise fitment.
Installation Guide: Step-by-Step for ICS2 MTT Hardware – Bumpers Black
Installing the ICS2 MTT Hardware – Bumpers Black is straightforward for those with basic bike maintenance skills, but we recommend professional assistance if you’re unsure. Here’s a simplified step-by-step process:
- Prepare Your Tools: You’ll need Allen keys (typically 4mm and 5mm), torque wrench, and possibly a stem removal tool.
- Remove the Old Bumpers: Loosen the preload bolt and wedge, then carefully extract the existing elastomers. Clean the stem internals to remove any debris.
- Select Your Hardness: Choose the appropriate bumper based on your weight and preference. For example, a 150lb rider might start with yellow for softer suspension, while a 200lb rider opts for black.
- Insert New Components: Place the selected bumper, rebound elastomer, and preload wedge into the stem. Secure with the M5x18 bolt, torquing to BMC’s recommended specs (usually 5-6 Nm).
- Test and Adjust: Reassemble the cockpit, go for a test ride, and fine-tune if needed by swapping bumpers.
