Carbon Spokes: Revolutionizing Road Wheelsets for Enhanced Performance

The cycling world has witnessed a remarkable shift in wheel technology, with carbon spokes emerging as a pivotal innovation. Once considered a niche, high-end feature, these advanced components are now reshaping the landscape of road bike wheelsets, offering a blend of performance enhancements that are becoming increasingly attainable for a wider range of cyclists. This evolution, exemplified by brands such as Superteam, signals a new era where superior wheel dynamics are no longer exclusive to professional circuits or exorbitant price tags, making high-performance cycling more accessible than ever before.

For a considerable period, carbon wheels represented the pinnacle of bicycle upgrades, a testament to performance that, for most riders, superseded the capabilities of their alloy counterparts. However, the progression of wheel technology has been relentless, pushing beyond mere rim materials. Recent years have seen the widespread adoption of broader rims and refined aerodynamic profiles. Concurrently, carbon spokes have steadily integrated into premium wheelset designs. Previously confined to professional teams or top-tier models commanding several thousand pounds, innovations from manufacturers like Superteam have democratized this technology, making it available at a far more approachable cost.

The key question then arises: do carbon spokes genuinely deliver a performance advantage, or are they simply a new talking point for the industry? To answer this, a comparison was conducted between a contemporary carbon-spoked wheelset and an older carbon wheelset featuring steel spokes. While not a direct like-for-like comparison, this evaluation effectively illustrated the significant strides made in wheel technology over time. The most striking distinction between the two wheelsets lay in their spokes. Carbon spokes, though not new, have evolved significantly. Earlier designs typically involved bonding spokes directly into hubs and rims. Today's iterations, such as those on Superteam's Ultra SL SE wheels, incorporate removable 3.2mm carbon spokes paired with titanium nipples. These are notably lighter, weighing in at a claimed 2.1g per spoke and nipple, compared to the Sapim CX-Ray steel spokes found in older models.

Rim designs have also advanced considerably. Rather than solely pursuing maximum depth, the Ultra SL SE wheelset features a 51mm front rim and a slightly shallower 48mm rear. This configuration is increasingly favored by leading manufacturers, aiming to mitigate crosswind instability while preserving aerodynamic efficiency. Furthermore, the newer rims are substantially wider, optimized for modern 28mm tires, in contrast to the older 60mm wheels designed for 25mm tires, which were then considered wide. This narrower profile made the older wheels considerably more challenging to manage in blustery conditions. Superteam's innovative 'shark fin' shaping on the rim profile is touted to enhance stability in crosswinds and reduce drag, with the company asserting an almost 18% reduction in aerodynamic drag at 40km/h compared to previous 25mm-wide designs.

To quantify these advancements, a practical test involved completing three laps of a local cycling circuit with each wheelset, striving to maintain consistent riding posture and power output. Given the inherent variability of outdoor testing, these results should be interpreted with caution. The older wheels completed the test in 7 minutes and 59 seconds from a standing start, while the newer wheels shaved off three seconds. This difference, while not revolutionary, is noteworthy considering the newer wheels are shallower than the 60mm older set, underscoring that aerodynamic improvements now extend beyond mere rim depth.

While flat road performance shows improvement, the true brilliance of carbon spokes emerges during climbs. The Ultra SL SE wheelset, with a claimed weight of only 1,220g, is remarkably lightweight for an aero-focused design. This, combined with the exceptional lateral stiffness provided by the carbon spokes, ensures an immediate response to acceleration and pedaling force. On steeper inclines, the bicycle exhibits a palpable eagerness. This enhanced stiffness also benefits heavier or more powerful cyclists; despite their low weight, these wheels support a generous rider weight limit of 120kg, offering lightweight performance without compromising durability. This upgrade, though difficult to measure precisely with a stopwatch, is profoundly perceptible from the saddle.

Historically, extremely stiff wheels often came with the drawback of a harsh ride. However, modern design has largely overcome this. The contemporary 23mm internal rim width, paired with larger 28mm tires, significantly contributes to rider comfort in ways older, narrower wheelsets could not. The hooked rim design further offers reassurance, particularly for those hesitant about hookless systems. While carbon spokes undeniably provide immense lateral stiffness, they do not inherently lead to an unforgiving ride. The evolution of wheel design has achieved a more harmonious balance, delivering impressive responsiveness without constantly reminding riders of imperfect road surfaces.

Considering the investment required, at £1,341, these wheels are not an impulsive purchase, especially for those who already possess a respectable carbon wheelset. However, it's crucial to consider the value proposition: carbon spokes, an exceptionally low claimed weight of 1,220g, DT Swiss 180 EXP hubs, ceramic bearings, and genuinely modern aerodynamic design. A comparable package from many established Western brands could easily exceed £3,000. While the marginal speed gains on flat terrain—a mere three seconds over a short test—might not seem life-altering, the profound benefits manifest in the overall riding experience. These wheels are lighter, demonstrably stiffer during climbs and accelerations, more stable in crosswinds, and better suited to current tire dimensions. Carbon spokes are no longer a mere marketing ploy; they represent a significant step in the broader evolution of wheel design, transforming deep-section aero wheels into highly versatile, all-around performers. Just a few years ago, the climbing prowess of a 50mm-plus wheelset of this caliber would have been unimaginable.
