Understanding Bike Headsets: The Foundation of Smooth Steering
Before we delve into the specifics of the Headset Roadmachine with Low Topcone, it’s essential to grasp what a bike headset does. At its core, a headset is the bearing system that connects your bike’s fork to the frame, allowing for smooth rotation of the handlebars. It consists of upper and lower bearings, a crown race, compression ring, top cap, and other components that work together to provide precise control while absorbing road vibrations.
Modern headsets come in various types, including threaded, threadless, integrated, and semi-integrated designs. The threadless variety, which is common in high-end road bikes like those from BMC, uses a star nut or bung inside the steerer tube for preload adjustment. This setup ensures minimal play in the steering, which is crucial for safety and efficiency during high-speed descents or sharp turns.
A low topcone, as featured in this particular headset, refers to a design element that lowers the stack height, allowing for a more aggressive riding position or better integration with certain stems and cockpits. This is especially beneficial for riders who prefer a slammed stem setup without compromising on comfort or cable routing.

Headsets are often overlooked during bike maintenance, but they play a pivotal role in overall bike feel. Worn bearings can lead to creaking, imprecise handling, or even safety issues. Upgrading to a high-quality option like the one we’re discussing today not only resolves these problems but also enhances the bike’s aerodynamics and aesthetics, particularly on models with integrated cable systems.
The BMC Roadmachine Series: A Perfect Match for Advanced Headsets
BMC’s Roadmachine series has earned a reputation as one of the most versatile endurance road bikes on the market. Launched as an all-road platform, it combines the speed of a race bike with the comfort needed for long hauls over varied surfaces. Models like the Roadmachine 01, Roadmachine 02, and Roadmachine AMP (with its electric assist) feature premium carbon frames, integrated cockpits, and tunable compliance technology that absorbs vibrations without sacrificing power transfer.
What sets the Roadmachine apart is its Integrated Cockpit System (ICS), which hides cables and hoses for a clean look and improved aero performance. The Headset Roadmachine with Low Topcone is specifically engineered to work within this ecosystem, supporting the ICS’s dual-stack top cones and proprietary spacers. This compatibility ensures that riders can maintain the bike’s sleek profile while achieving a custom fit.
According to BMC’s official documentation, the Roadmachine is designed for riders who demand versatility—whether commuting, racing, or adventuring on gravel paths. The series supports tire clearances up to 33mm (or more in some configurations), making it ideal for mixed-terrain exploration. Pairing it with the right headset enhances this versatility by providing buttery-smooth steering that’s responsive yet forgiving.

Key Features of the Headset Roadmachine with Low Topcone
Now, let’s break down what makes the Headset Roadmachine with Low Topcone stand out. This kit is more than just a replacement part; it’s a precision-engineered upgrade tailored for BMC’s endurance road bikes.
First and foremost, it includes high-quality sealed bearings—both upper and lower—for long-lasting performance and protection against dirt, water, and debris. These bearings are designed to reduce friction, ensuring effortless steering even after thousands of miles. The low topcone design allows for a reduced stack height, which is perfect for riders seeking a more aerodynamic position or those using the ICS stem without additional spacers.
The package comes complete with essential components: a split ring for secure fitting, a topcone for flat steerers, and another for round steerers. This versatility means it can adapt to different fork configurations within the Roadmachine family. Priced around $59 USD, it’s an affordable way to refresh your bike’s front end without breaking the bank.
In terms of build quality, BMC uses durable materials that match the premium standards of their bikes. The black finish blends seamlessly with most Roadmachine color schemes, maintaining that factory-fresh appearance. Users often praise its ease of integration with the bike’s D-shaped steerer tube, which facilitates internal cable routing for brakes and shifters.

One notable feature is its compatibility with the Roadmachine AMP’s Mahle e-bike system, where smooth steering is critical for handling the added weight and power. This headset ensures that electric-assisted rides feel just as natural as traditional ones.
Compatibility and What’s Included in the Box
Compatibility is key when selecting bike parts, and the Headset Roadmachine with Low Topcone excels here. It’s officially listed for use with the Roadmachine, Roadmachine 01, Roadmachine 02, and Roadmachine AMP models. If your bike is from 2017 or later, this headset should fit perfectly, especially if you’re running the ICS cockpit.
Inside the box, you’ll find:
- 1x Upper bearing
- 1x Lower bearing
- 1x Split ring
- 1x Topcone for flat steerer
- 1x Topcone for round steerer
This comprehensive kit means you won’t need to hunt for individual pieces, saving time and hassle. Note that while it’s designed for BMC bikes, some users have adapted it to similar frames with minor modifications, though we recommend sticking to official compatibility to avoid voiding warranties.
For those with older models, check BMC’s ICS compatibility document for detailed charts on stack heights and stem options.
Step-by-Step Installation Guide
Installing the Headset Roadmachine with Low Topcone is straightforward for those with basic mechanical skills, but if you’re unsure, consult a professional bike shop. Here’s a general guide based on standard practices:
- Preparation: Gather tools like a headset press, bearing remover, Allen keys, and grease. Remove the front wheel, stem, and fork from the frame.
- Remove Old Headset: Use the bearing remover to extract the old upper and lower bearings. Clean the head tube thoroughly.
- Install New Bearings: Press the lower bearing into the frame first, followed by the upper. Ensure they’re seated evenly.
- Add Components: Slide the crown race onto the fork (if not pre-installed), then insert the fork into the frame. Add the split ring, chosen topcone (low for minimal stack), and compression ring.
- Preload and Secure: Reattach the stem and spacers, then use the top cap to preload the bearings. Tighten to eliminate play without binding.
- Test: Reinstall the wheel and test steering for smoothness. Adjust as needed.
BMC provides video tutorials on their YouTube channel for ICS-related installations, which can be helpful for visualizing the process.

Benefits: Why Upgrade to This Headset?
Upgrading to the Headset Roadmachine with Low Topcone offers numerous advantages. Primarily, it improves steering precision, which translates to better control on descents and corners. The low topcone allows for a customized fit, reducing neck strain on long rides by enabling a lower handlebar position.
Durability is another win; the sealed bearings resist contamination, extending service intervals. Riders report fewer creaks and a more responsive feel, especially on rough roads where the Roadmachine’s compliance shines. For e-bike users on the AMP model, it handles the extra torque without compromise.
Aesthetically, it maintains the clean lines of your BMC bike, enhancing resale value. Plus, at under $60, it’s a cost-effective upgrade compared to full cockpit replacements.
User Reviews and Real-World Experiences
