In the world of cycling, particularly for those riding high-performance bikes with carbon rims, the choice of brake pads is paramount. It’s not just about slowing down; it’s about control, confidence, and safety, especially when descending at speed or navigating unpredictable urban environments. SwissStop, a name synonymous with quality braking, has long been a go-to for serious cyclists. Their Yellow King pads have been a benchmark for carbon rim performance for years, offering reliable stopping power. However, the cycling landscape is always evolving, and last summer, SwissStop introduced a new contender to the top of their carbon rim brake pad lineup: the Black Prince. This new pad promises to elevate the braking experience even further, claiming a more linear braking force and improved heat management. But does it truly unseat the Yellow King as the reigning champion? Let's delve into the details and find out.
The Quest for Superior Stopping Power
The primary function of any brake pad is to convert kinetic energy into heat, thereby slowing down or stopping your bicycle. However, the 'how' of this conversion makes all the difference. SwissStop’s Black Prince pads claim to offer a more linear braking force. This means that the amount of braking power you get is directly proportional to the force you apply at the brake lever. Unlike pads that might feel 'grabby' initially and then plateau, or those that require a lot of force for little effect, a linear response ensures precise modulation. It allows riders to feather their brakes with incredible accuracy, crucial for maintaining speed in a paceline or navigating technical descents without skidding. The Black Prince pads reportedly deliver this linear braking experience, offering a level of control that feels intuitive and highly effective.
My personal experience with the Black Prince pads was nothing short of impressive. They truly allowed me to 'stop on a dime', providing instant and powerful deceleration. Whether it was reacting to sudden traffic changes or coming to a complete halt from high speeds, the pads engaged predictably and firmly. This immediate response significantly boosts rider confidence, knowing that precise braking is always at your fingertips. The pads are phenomenally grabby, and I mean that in a good way; the braking comes on predictably – not too abruptly, but you know they’re working instantly.
Mastering Heat Management
One of the biggest challenges with carbon rims is heat build-up during braking, which can lead to rim damage, reduced braking performance, or even tyre blowouts in extreme cases, a phenomenon known as 'brake fade'. SwissStop claims a remarkable 35% reduction in maximum heat generated during severe braking tests (from 60km/h to zero). This is a substantial improvement, especially considering the speeds easily attainable on downhill sections. During my testing, which included simulated emergency stops and prolonged brake dragging on descents (like an eighth of a mile), I never experienced any loss of power or noticeable fade. This exceptional heat management ability is incredibly confidence inspiring, particularly for riders who frequently tackle long, steep descents where consistent braking is critical. The pads maintained their power and feel even after extended efforts, providing a consistent and reassuring performance.
Design and Durability: More Than Meets the Eye
Physically, the Black Prince pads feature deeper grooves compared to some OEM pads, even those manufactured by SwissStop for other brands like SRAM. This design isn't just for aesthetics; it plays a crucial role in performance. The deeper grooves are engineered to improve airflow across the rim surface, aiding in heat dissipation and helping to clear water and debris in wet conditions. This improved airflow is particularly beneficial during long, fast descents where heat build-up is a primary concern.
However, a trade-off of this design is that these grooves tend to collect brake dust and other road grime. While I didn't observe any unusual noises or scratching during my rides, it's a sensible practice to clean these grooves regularly. This simple maintenance step ensures optimal airflow, particularly vital for maintaining consistent performance and preventing any small, abrasive particles from potentially damaging your valuable carbon rim surface. Regular cleaning also helps to maximise the lifespan of both your pads and your rims.
Performance Across Conditions
My testing regimen for the Black Prince pads was varied, designed to assess their performance in a range of real-world scenarios. They were put through their paces on both open-mold carbon rims (Culprit's first generation wheels) and high-end ENVE Smart 6.7 rims. In both instances, replacing the original ENVE pads with the Black Prince resulted in a dramatically improved braking experience for everyday riding. From pleasant, mild temperatures to near-freezing conditions, and in both dry and drizzling rain, the pads consistently delivered.
Even in light rain, they maintained reliable stopping power in a remarkably short distance, a critical safety feature often compromised with carbon rims. The transition from dry to wet conditions felt seamless, instilling greater confidence when riding in unpredictable British weather. For typical flatter terrain riding, involving gentle feathering in a paceline, navigating stop lights, and reacting to traffic, the Black Prince pads proved to be phenomenally grabby – and I mean that in the best possible way. The engagement was instantaneous yet predictable, avoiding any abruptness that could unbalance a rider. The direct correlation between lever force and braking intensity, particularly when paired with modern brake systems like the new SRAM Red, was consistently evident across the entire speed spectrum. The pads did exhibit a slight stick to the ENVE rims for a fraction of a second when squeezing the levers hard at a standstill, but this behaviour was never noticeable or problematic during actual riding.
Black Prince vs. Yellow King: The Showdown
While direct comparative data for the Yellow King wasn't provided in my testing, the Black Prince's claims of more linear braking force and significant heat reduction directly challenge the Yellow King's established reputation. The Yellow King has long been lauded for its strong initial bite and consistent performance, making it a favourite among discerning cyclists. However, the Black Prince appears to refine this further with its emphasis on modulation and superior heat management, pushing the boundaries of what's possible with carbon rim braking.
Crucially, both pads are positioned at the premium end of the market, with the Black Prince matching the Yellow King's Recommended Retail Price (RRP) of approximately £40 for a four-pack. This price parity makes the Black Prince an even more compelling proposition for those seeking the absolute best in carbon rim braking, offering enhanced performance without an additional cost premium over its highly regarded predecessor.

Frequently Asked Questions
How often should I replace my brake pads?
The lifespan of brake pads varies significantly depending on riding conditions, frequency of braking, and rider weight. For carbon rim pads like the Black Prince, it's crucial to inspect them regularly for wear, typically before every significant ride or weekly. Look for the wear lines on the pad; once these are no longer visible, or if the pad material is thinning significantly, it's time for replacement. Also, check for any embedded debris that could scratch your rims. Timely replacement not only ensures optimal braking but also protects your expensive carbon rims from undue wear or damage.
Are SwissStop Black Prince pads compatible with all carbon rims?
SwissStop designs their carbon-specific pads, including the Black Prince, to be compatible with a wide range of carbon rims. They are engineered to work effectively with various carbon brake track finishes. However, it's always recommended to check with your specific rim manufacturer's guidelines, as some may specify particular pad types to maintain warranty coverage or ensure optimal performance. Generally, if your carbon rims are designed for standard rim brakes, these pads should work exceptionally well, delivering superior performance over many OEM options.
What's the best way to clean brake pads and rims?
Regular cleaning is vital for optimal performance and rim longevity. For the pads, use a small, stiff brush or a pick to carefully remove any embedded grit or accumulated brake dust from the grooves. For the rims, a clean cloth dampened with rubbing alcohol (isopropyl alcohol) or a dedicated carbon rim cleaner works wonders. Always ensure rims are completely dry before riding, especially if using a wet cleaner. This prevents slipping and ensures immediate braking effectiveness. Cleaning helps maintain the integrity of your brake track and prevents abrasive particles from causing damage.
What does 'linear braking force' really mean for my ride?
Linear braking force means that the amount of braking power you get is directly proportional to the force you apply at your brake levers. If you press the lever twice as hard, you get roughly twice the braking power. This provides a very predictable and controllable braking experience, allowing for fine modulation. It helps prevent accidental skidding or over-braking, making your ride smoother and safer, particularly in technical situations or emergencies. It allows for a more intuitive feel, where the rider can precisely control their speed with minimal effort and maximum confidence.
Are SwissStop pads worth the investment over cheaper alternatives?
For riders with carbon rims, investing in high-quality brake pads like SwissStop Black Prince is highly recommended. Cheaper pads can often lead to reduced stopping power, excessive heat build-up (potentially damaging your expensive carbon rims), annoying squealing noises, and poor wet-weather performance. The enhanced safety, control, and peace of mind offered by premium pads far outweigh the initial cost saving of inferior alternatives. Considering the significant investment in carbon wheels, pairing them with the best possible brake pads is a sensible decision for both performance and longevity.
