Quad's Dime Pro RA: A Detailed Brake Review

In the world of bicycle braking systems, choosing the right set can significantly impact your riding experience, particularly when tackling challenging terrain or demanding descents. Quad's Dime Pro RA disc brake has emerged as a contender, aiming to blend advanced features with robust performance. This review will delve into what makes the Dime Pro RA tick, examining its design, adjustability, and real-world effectiveness, especially when compared against its peers.

Design and Features of the Quad Dime Pro RA

The Quad Dime Pro RA is a disc brake system that doesn't shy away from packing in a multitude of features. At first glance, its design is modern and somewhat aggressive. The master cylinder, described as chunky, sports a radial style, a design choice that has become increasingly popular for its potential to offer improved leverage and feel. This is complemented by a reach-adjust wheel, allowing riders to customise how far the lever sits from the handlebar, catering to different hand sizes and preferences. Adding a touch of flair, the gold anodising on these adjustment bits, along with the caliper bore caps, provides a subtle yet noticeable aesthetic upgrade, a nod to those who appreciate the 'bling' factor in their components.

Further enhancing its customisation capabilities, the Dime Pro RA features an independent bite point adjuster. This crucial element allows riders to fine-tune the point at which the brake pads engage with the rotor. This level of adjustability is highly sought after by enthusiasts who enjoy 'fine feel fettling,' meaning they want to dial in the precise feel and response of their brakes. The lever blade itself is long, providing ample surface area for comfortable and secure grip.

Rotors and Weight Considerations

Quad has opted for their 'Pulse' rotors, which are designed with a wavy pattern. The intention behind this design is to help push out dirt and debris, a common issue that can compromise braking performance, especially in adverse weather conditions. The effectiveness of these rotors in keeping the brake running clean, even in the worst winter grime, has been noted in testing. However, it's also important to acknowledge that these distinctive wavy rotors contribute to the overall weight of the brake system. The Dime Pro RA, as a package, has been described as heavy, and the rotors are a significant part of this 'pound-per-end weight,' as it's been put.

Performance in Various Conditions

Real-world testing has provided valuable insights into the Dime Pro RA's performance. For months, riders have been using this brake regularly, and the feedback points towards impressive control and power, particularly when riding through mud and filth. This suggests that the brake is well-equipped to handle the challenges of off-road cycling in less-than-ideal weather. The dyno results have also been above average, lending credence to the claims of strong braking capability.

However, the picture isn't entirely rosy. While adequate for average trail use, the brake's performance becomes less impressive when pushed hard. The contact point adjustment feature, while intended to enhance feel, can lead to a compromise. Riders might find the brake either feels soft and spongy, or they have to dial in excessive reach. This excessive reach can result in the lever hitting the handlebar before achieving proper stopping power, a scenario that can be disconcerting and potentially dangerous on steep or fast descents.

Ease of Installation and Maintenance

When it comes to fitting and maintaining the Dime Pro RA, Quad has incorporated features designed for user convenience. The adjustable hose rose allows for flexible routing of the brake hose, making it easier to achieve a clean and tidy setup on the bike. Furthermore, the syringe-based bleeding system simplifies the process of removing air from the hydraulic lines, a crucial step in ensuring optimal braking performance. This makes it easier for users to 'fettle' their brakes themselves.

A point of consideration, however, lies with the brake pads. The Quad Dime Pro RA uses unique bottom-loading pads. While spares are available through Raleigh dealers, the specific nature of these pads means they aren't as universally easy to find as more common pad types. This could be a minor inconvenience for riders who frequently need to replace worn pads and prefer the widest possible availability of spares.

Comparative Analysis: Power and Feel

The Dime Pro RA's power and control are described as adequate for average trail use. This means that for general cross-country riding or less aggressive downhill trails, the braking performance should be sufficient. However, the trade-off for this adjustability, particularly with the bite point, can be a less consistent feel. The brake is either set up for a softer, more modulated feel, or it requires a significant reach adjustment that can compromise the lever's full range of motion.

This nuanced performance characteristic leads to a crucial recommendation: if your riding involves tackling 'big hills' or consistently demanding descents, the Dime Pro RA might not be the ideal choice. The limitations in achieving consistent stopping power under heavy load, coupled with the potential for lever-to-handlebar contact, suggest that more potent and less finicky braking systems might be better suited for extreme use.

Frequently Asked Questions (FAQ)

Q1: Is the Quad Dime Pro RA a powerful brake?
A1: The brake offers adequate power for average trail use and has shown impressive control in adverse conditions. However, its power can become less impressive when worked hard, particularly on steep descents.

Q2: Can I adjust the feel of the Quad Dime Pro RA?
A2: Yes, the Dime Pro RA features independent reach and bite point adjusters, allowing for fine-tuning of the lever feel and engagement point.

Q3: Are spare brake pads easy to find for the Quad Dime Pro RA?
A3: The brake uses unique bottom-loading Quad pads. While spares are available through Raleigh dealers, they are not as universally common as other pad types.

Q4: Is the Quad Dime Pro RA suitable for downhill riding?
A4: Due to limitations in consistent stopping power under heavy load and potential lever-to-handlebar contact, it is generally recommended to opt for more powerful brakes if your riding involves significant downhill sections or 'big hills'.

Q5: What is the main drawback of the Quad Dime Pro RA?
A5: The primary niggle identified is the brake's high weight, contributed in part by the rotors.

Conclusion

The Quad Dime Pro RA disc brake presents a compelling package for riders who value adjustability and a refined lever feel for general trail riding. Its modern design, coupled with features like independent reach and bite point adjustment, allows for a personalised braking experience. The inclusion of 'Pulse' rotors also aids in maintaining performance in dirty conditions. However, potential buyers must weigh these benefits against the brake's significant weight and its limitations when subjected to the rigours of demanding downhill riding. For the rider who enjoys tinkering and prioritises customisation for everyday trails, the Dime Pro RA could be a worthy consideration. For those who demand unwavering power and reliability on the most challenging terrain, exploring other options might be more prudent.
