Five Tested Road Bike Upgrades: Helmet, Glasses, Wheels, Tires, and Jersey

Introduction

Road bike upgrades can transform how a bike feels and performs. Over the past several months, we have tested five products across a range of bikes and conditions, from heat waves to wet cobbles. These are not just any components: they are used by professional teams and designed to deliver marginal gains. The selection covers protection, vision, rolling speed, grip, and aerodynamics. Each product has its own strengths and trade-offs, and this guide will help you decide which ones are worth your money.

The five products include a premium helmet with advanced safety features, customizable sunglasses with a versatile lens, a high-performance wheelset, fast and durable tubeless tires, and an aero jersey that promises real speed benefits. We focused on real-world performance: comfort, durability, ease of installation, and whether the claimed advantages show up on the road.

Whether you are racing, training, or simply looking to upgrade your ride, these products represent some of the best options available today. But as with any upgrade, the value depends on your priorities and budget.

Kask Elemento: Premium Protection and Comfort

The Kask Elemento is the most expensive helmet we have ever tested, with a price of £335. It features visible carbon panels on the outside, running from the middle down to the back and along the sides. These panels are not just for looks; they boost impact protection and helped the helmet earn a 5-star rating in the Virginia Tech independent helmet test.

Inside, the carbon panels allow for much bigger channels for air to flow through the helmet and over your head. During a recent heat wave, these large channels kept the head cool for a semi-aero helmet. It is not as airy as some pure ventilation helmets, but for an aero-focused design, it performs well.

The padding is a standout feature: 3D printed squishy pads in the middle provide amazing comfort across the head. Combined with the large cradle of the retention system, the helmet almost disappears on your head. It is perhaps the comfiest helmet we have ever used, with no pinch points or pressure hotspots. This padding also reduces rotational impact in a crash, their version of MIPS without using MIPS.

The retention cradle offers loads of adjustment, including on-the-fly tuning with a wheel. The straps are very lightweight, and the buckle is simple, though not magnetic. The large brow pad works well most of the time, but it is not the best at holding sweat during hard efforts in a chain gang, where sweat can drip down the forehead more than with other aero helmets.

Overall, the Kask Elemento is lightweight, well ventilated, easy to adjust, and aerodynamic according to the company’s claims. However, it is hard to justify the high price when you can get a very good helmet that meets the same safety standard for a fraction of the cost. If you want cutting-edge technology and are prepared to pay for it, this is one of the best helmets available. For everyone else, the value proposition is tough.

Sun God Villain: Customizable Eyewear for Fast Riding

The Sun God Villain is a half-frame design that is lightweight, fits well, and offers good lens quality. Buying through the Sun God website is a slick process with many choices for frame design and color combinations. You can also customize the frame color, logo, and lens, which is what we did. The result looks pretty cool, and the tall frame is not dissimilar to the Oakley Sutro Lite.

The fit is good, at least for us, with four different nose pieces to customize to your nose size. The ears are slim and have a nice grippy material on the arms to keep them in place. They work with different helmets we have used, including Giro, HJC, Kask, and Specialized, with no interference with the retention system.

The lenses come in many different shades. The Iris Blue lens we tested works well in low light conditions and can adapt to light levels, making it great for places like the UK where it is not always sunny and you are riding in and out of trees. The clarity and quality of the lens is good, and durability seems good too, with no scratches so far.

At £150, the Villain is in the Oakley ballpark in terms of price. However, the hinges are a bit stiffer and not quite as slick as Oakleys. They are plastic glasses at the end of the day, but generally durability has been good. The customization process and the company’s push for sustainability might be factors when buying. If you want to imitate pro riders, these are the shades to have.

ENVE SES 4.5: Fast, Stable, and Built to Last

The ENVE SES 4.5 is a go-to choice for many professionals, used by the UAE Team Emirates. We have been riding a set for the last four or five months on a range of bikes with different tires, and performance is top level. The wheels strike a good balance of weight, aerodynamics, and all-round usability, making them an easy pick for racing, training, and just riding everywhere.

ENVE uses a mixed depth rim: 55mm at the back and 49mm up front. They are also wide, with a 25mm internal width, making them ideal for fat tires. They are tubeless only with a hookless bead. While this might concern some, there are loads of good compatible tires now available, and installation is a breeze with a normal track pump: the tires pop up with no fuss or drama.

Over five months of hard riding in tough conditions, the wheels have been faultless. They have not gone out of true, and the spokes have not come loose. The spoke nipples are inside the rims for more aero, which is a downside if you want a wheel set that is easy to maintain, but it has not been an issue because the wheels are really well made. The ENVE Hub spins smoothly with double sealed bearings that stand up well to British weather and hose washing. The freehub engages quickly, though perhaps not the quickest on the market, but certainly quick enough.

You can upgrade to ceramic speed bearings if you want, but ENVE is quite transparent in saying they are probably not worth the cost compared to its own steel bearings. What makes these wheels stand out is their general high performance across every aspect. They are clearly fast, offer rigidity and stability in windy conditions, and the weight is pretty good at 1450 to 1500 grams, in the same ballpark as similar offerings from Roval or Zipp. If you are a climber and want a lighter wheel set, the SES 2.3 or 3.4 might be better. If you want more aero, the 6.7 is an option. But for rolling roads, these are the epitome. They feel good on any bike, with easy speed, great cornering agility, and ample stiffness. There is no disc brake rub to speak of.

The wheels are expensive because they are made in the US, where most carbon wheels are made in Taiwan, and they are backed by a really good warranty. The difference in speed between these and a cheaper wheel set might be small, as the gap has narrowed over the last 10 years. But the extra details and robustness really stand out. ENVE has long been a benchmark premium wheel brand, and while competition has got closer from cheaper rivals and carbon spoke wheels, for a fit-and-forget wheel set that looks fantastic and rides amazing, they are worth considering.

Continental Grand Prix 5000 S TR: Fast and Durable Tubeless Tires

The Continental Grand Prix 5000 S TR is one of the top picks in the pro peloton, and after riding them for the last five months, it is easy to see why. They are fast, durable, and easy to fit. Installation is much easier than the old 5000 TL, which was a nightmare. These go on the rim really nicely with no tire levers needed in most cases and inflate with a normal track pump, just how tubeless should be.

We tried these on different rims from Hunt, ENVE, and others over the last few months and had no issues at all. They are now compatible with hookless rims as well. We tested the 28mm wide version, and they come in narrower and wider sizes. The 28mm size is popular in the pro peloton and on our race bikes.

The ride feel and quality of the tires is very good. They are similar to the original GP5000, which replaced the GP4000, so they are a very big run of tires. We have ridden them in all sorts of conditions, from hot baked roads to wet gritty cobbles in Belgium, and they deliver fantastic speed and reliable, reassuring grip. The Black Chili compound is fantastic, both grippy in all conditions and with low rolling resistance. The website Bicycle Rolling Resistance found the 25mm wide version to be one of the best in its class.

Durability has been good so far. The tire has not cut or marked at all, and they still look pristine. Wear has been good too, with no excessive wear. That is good because some top-end race tires can be fantastically fast and supple but feel fragile and prone to cuts and punctures. These do not appear to be like that at all, giving confidence that they will last a long time and survive quite punishing riding. We have not yet punctured them, though these are pretty expensive, so we are not keen to do a puncture test and write them off.

Castelli Aero Race Jersey: Tight Fit, Real Aero Gains

The Castelli Aero Race Jersey has been evolving and adapting for the last 10 years, and the latest version promises more marginal gains for going faster. It is a very tight fitting jersey, so getting the size right is crucial. Once you do, it fits really well, and the comfort is surprisingly good. I thought it would be uncomfortable, but it is actually okay even on long rides.

The long sleeves have a seamless raw cut edge, which is nice and comfy. The fabric is soft against your skin, which is fantastic if you are not wearing a base layer in hot weather. With a mesh panel on the back, it copes really well in hot weather too, better than I thought an aero jersey would. I was expecting to overheat, but that was not the case. There are three pockets at the back, but no zipper pocket, which is the only real blemish on the jersey in my opinion.

Castelli says the aero benefits of the jersey kick in above 30 km/h, so it is definitely a jersey for those racing or riding fast, doing chain gangs, or just concerned with average speed. Personally, I am not a massive fan of the long sleeves on modern jerseys, but I guess it is more aero. I do prefer shorter sleeves normally. Considering Castelli is a premium high-end brand and usually pretty expensive, this jersey is surprisingly £50 cheaper than their Rafale pro team Aero Jersey, so it is pretty good value for the aero gains you get. It is available in different colors and a range of sizes, making it a good pick if you want to go faster without buying a new aero frame or new aero wheels.

Overall Buying Advice

These five products represent different priorities and budgets. The Kask Elemento is for riders who value cutting-edge safety and comfort and are willing to pay a premium. The Sun God Villain offers customizable eyewear with a versatile lens at a price that competes with established brands. The ENVE SES 4.5 is a premium wheelset for those who want all-round performance and durability without fuss. The Continental Grand Prix 5000 S TR delivers speed, grip, and easy tubeless installation for a relatively high but justifiable cost.
