Bontrager Aeolus 5 Wheels: Understanding the Cork Brake Pads
When discussing the Bontrager Aeolus 5 TLR D3 carbon clincher wheels, a common point of inquiry revolves around the brake pads, specifically whether they include cork pads. The short answer is yes, Bontrager does offer cork brake pads as an option for their Aeolus 5 wheels, and they are indeed supplied with the wheels. However, their performance, particularly in adverse weather conditions, warrants a closer look. This article will delve into the specifics of these cork pads, their benefits, drawbacks, and the alternatives available for your Bontrager Aeolus 5 wheelset.
The Aeolus 5 TLR D3: An Overview
The Bontrager Aeolus 5 TLR D3 wheels represent a significant entry into the growing market of aero carbon clinchers. These wheels are designed for speed and stability, boasting a 50mm rim depth and a 19.5mm internal rim width, which Bontrager claims offers improved aerodynamic performance and a more stable platform for wider tyres. They utilise high-quality DT Swiss hubs, known for their reliability and smooth engagement, featuring the star ratchet system. The overall build is praised for its stiffness, light weight (around 1,470g for the set without quick releases or rim strips), and durability, even when subjected to rough road conditions.
Bontrager offers these wheels with a tubeless-ready setup, which brings its own set of advantages and considerations, such as improved ride comfort and puncture resistance through sealant. However, the question at hand is about the braking experience, and for that, the brake pads are crucial.
Bontrager's Brake Pad Recommendations
Bontrager provides users with a choice when it comes to brake pads for their Aeolus 5 wheels. They recommend two primary types:
- SwissStop Black Prince pads: These are suggested for riders seeking more stopping power, often referred to as having 'more bite'.
- Bontrager Carbon Stop Cork options: These are designed to offer a 'softer feel' at the brake lever.
The wheels are supplied with the cork pads, and many users, including reviewers, have noted their positive attributes. The cork pads are appreciated for their predictable contact with the carbon rim and the satisfyingly quiet braking experience they provide. The lack of screeching, a common issue with some carbon brake pads, is a definite plus. This smooth, quiet operation contributes to a pleasant ride feel, especially when combined with high-quality calipers like the Shimano Dura-Ace 9000.
The Performance of Cork Pads
In dry conditions, the cork pads perform admirably. They offer solid, predictable braking power that is generally considered adequate for most riding scenarios. The tactile feedback from the cork is reassuring, giving the rider confidence in their ability to modulate speed. The gentle engagement and quiet operation are highlights that many riders will appreciate.
However, the narrative changes when the weather turns wet. The provided information explicitly states: "you don't want to use the supplied cork pads when it's wet." This is a critical point. While the cork pads offer a softer feel and quiet operation in the dry, their performance deteriorates significantly in wet conditions. Braking power is reduced, and the predictability can be compromised, making them a less-than-ideal choice for rainy rides. In such scenarios, the SwissStop Black Prince pads are strongly recommended as a superior alternative for their enhanced wet-weather grip and stopping power.
Cork vs. SwissStop Black Prince: A Comparison
To better illustrate the differences, here's a comparative look at the two recommended pad types:
| Feature | Bontrager Carbon Stop Cork | SwissStop Black Prince |
|---|---|---|
| Dry Performance | Good, predictable, quiet, soft feel. | Very good, strong bite, reliable. |
| Wet Performance | Poor, reduced power, less predictable. | Excellent, strong power, reliable. |
| Noise | Very quiet. | Can be slightly squeaky at times. |
| Feel | Softer, more modulated. | More direct, powerful. |
| Recommendation | Dry conditions, riders prioritizing comfort and quiet. | All conditions, especially wet, riders prioritizing stopping power. |
The Tubeless System and Pad Changes
While the cork pads themselves are a point of discussion, the tubeless system integrated into the Aeolus 5 wheels also introduces some practicalities regarding brake pads. The tubeless setup requires specific rim strips, which are designed to seal the rim for tubeless use. Changing tires with this system can be more involved than with traditional clinchers, and sometimes necessitates replacing the rim strip. This process, while not directly related to the brake pads' function, is part of the overall user experience with these wheels.
When it comes to changing brake pads, it's a straightforward process inherent to rim brakes. The cork pads, being supplied with the wheels, are the initial setup. If a rider decides they need better wet-weather performance or simply prefer the feel of the Black Prince pads, they can be swapped in relatively easily. The critical aspect is ensuring that the chosen pads are specifically designed for carbon rims to avoid damage.
Frequently Asked Questions
Q1: Do the Bontrager Aeolus 5 wheels come with cork brake pads?
Yes, the Bontrager Aeolus 5 wheels are supplied with Bontrager's Carbon Stop Cork brake pads.
Q2: How do the cork brake pads perform in wet weather?
The cork brake pads offer significantly reduced performance in wet conditions, with less stopping power and predictability. They are not recommended for wet riding.
Q3: What are the alternatives to the cork brake pads?
Bontrager recommends the SwissStop Black Prince pads as a superior alternative, especially for wet weather, offering more bite and reliable stopping power.
Q4: Are the cork pads noisy?
No, the cork pads are generally very quiet and do not produce the screeching often associated with carbon brake pads.
Q5: Can I use other brake pads with the Aeolus 5 wheels?
While other pads designed for carbon rims might work, Bontrager specifically recommends their cork option or the SwissStop Black Prince pads for optimal performance and safety.
Conclusion: A Tale of Two Conditions
The Bontrager Aeolus 5 TLR D3 wheels are undoubtedly a high-performance wheelset, offering speed, stability, and a refined ride feel. The inclusion of cork brake pads is a deliberate choice by Bontrager, aimed at providing a quiet and comfortable braking experience in dry conditions. For riders who predominantly ride in fair weather and appreciate a subtle braking feel, the supplied cork pads will likely suffice and even impress. However, for those who frequently encounter wet roads or prioritise maximum stopping power in all conditions, investing in the recommended SwissStop Black Prince pads is a wise decision. Understanding the limitations of the cork pads in the wet is key to ensuring safe and confident riding across the full spectrum of cycling weather.
