Aero meets Performance or the reference wheel in the aero wheel section for your road bike
The Lightweight FERNWEG is an aerodynamic wheel, available in two different profile heights and perfectly suited for a triathlon or ironman. Through months of testing in the wind tunnel and cooperation with various aerodynamics specialists and professional triathletes, Lightweight was able to develop a new construction based on the Lightweight MEILENSTEIN. The result is the Lightweight FERNWEG, a top carbon wheelset in the combination of aerodynamics, crosswind resistance, stiffness, handling and weight. The low rolling resistance leads you more easily to your goal, increases your speed and makes you more effective. Crosswinds do not disturb the FERNWEG and let athletes get the maximum performance out of the aero position. Where riders with other wheel products have to leave the aero position, the FERNWEG rider still lies on his handlebars and rides away from the competition.
The advantages and disadvantages of an Aero wheel set
When it comes to aerodynamics, wheels play a decisive role, but only at high speeds from around 40 km/h. Rim height and aerodynamics are inseparably linked. The high rim dissipates the airflow better, thus ensuring less drag and you can put more speed on the road. Additionally every racing bike with high-profile wheels looks faster and more aggressive and becomes a real eye-catcher on the road. High profile wheels are the epitome of a fast and beautiful aero or time trial bike.
A disadvantage of these wheels, however, is that the height of the rim makes them more sensitive to strong crosswinds. Furthermore, the weight often increases because the wheel has a higher rim.
The high art is to find the perfect mix and balance between handling, weight, aerodynamics and wind sensitivity. Every manufacturer finds his own way here and implements his own standards and ideas of the perfect wheel.
Disc brakes on an aero wheel
The braking performance of disc brakes is significantly better than the braking force over the brake flank. Disc brakes, however, cause a little more weight and losses in aerodynamics. Disc brakes cause less wear and tear on the wheel itself, as the braking surface wears independently of the rim, therefore the high profile wheels in the disc version are more durable. So the road cyclist has to decide what to focus on and whether to use rim brakes or disc brakes.
The new FERNWEG convinces with its values and is The Aero Carbon Road Bike Wheelset
Higher, faster, further. Our new aerodynamic carbon wheel is based on the Lightweight MEILENSTEIN and shines with the acceleration and STW values of the Lightweight MEILENSTEIN.
With the help of wind tunnel data, we tinkered with the aerodynamic advantage for the new, lightweight aero wheel from Lightweight. Tests were conducted with aerodynamics specialists and professional triathletes until the ideal shape and profile height were found. The result is a new, unique and aerodynamic high profile wheelset with absolutely impressive performance values from the wind tunnel. The combination of aerodynamics, crosswind resistance, stiffness, handling and weight ensure an unprecedented smoothness of your ride.
Every manufacturer has to make compromises when developing an aero wheel set. With the FERNWEG, Lightweight has an aero wheel in its portfolio that convinces with its combination of weight, stiffness, air resistance and wind sensitivity and makes a balanced ride possible.
The Lightweight FERNWEG is an aero wheelset with extremely high stability, a relatively low weight and an optimal weight distribution. The FERNWEG 85 mm disc wheelset weighs just 1765 g, the 63 mm disc set 1695 g. The 85 mm non-disc version (rim brake) weighs 1625 g in the clincher version and 1500 g as a tubular set. The 63 mm variant for rim-braked road bikes weighs 1560 g in the clincher version and 1435 g as a tubular version.
The fight for every single gram can be at the expense of stiffness. Lightweight is known for best values regarding stiffness. This also continues with the FERNWEG. At 80 Newton per millimetre (N/mm) the aerodynamic wheels are on average around 20 N/mm stiffer than comparable aero rims. The high stiffness of Aero wheels ensures agile handling and good acceleration.
Especially in crosswind conditions, the new design of the long-distance track comes into its own. Practical tests clearly showed that the triathlete has to leave his aerodynamic seating position later, as the wheel remains stable for a long time. This was also confirmed in the wind tunnel. Here, the FERNWEG shows a lower wind sensitivity than comparable competitors, even in crosswinds. This secures valuable seconds and ensures a comfortable ride.
The full carbon wheels from Lightweight FERNWEG at a glance
Modern aerodynamic carbon high profile rims not only have lower air resistance, but also possess a number of other properties:
Low susceptibility of the wheelsets to cross winds and gusts
Reduced air resistance with lateral inflow up to the gliding effect (possibility of propulsion)
Very stiff wheelset due to new construction compared to the predecessor, optimized carbon layer structure and laminated spokes
Good braking behaviour and longer wheel life due to local laminate reinforcement on the brake tracks
Very good braking performance of the DISC version, not least thanks to the innovative pentagon hub
Better steering behaviour and improved aerodynamics compared to the previous model
Light weight despite high rim
The models FERNWEG C 63, FERNWEG C 85, FERNWEG T 63, FERNWEG T 85, FERNWEG EVO 63 and FERNWEG EVO 85 are UCI-compliant (comply with the applicable UCI rules)
Available in numerous variants
The new FERNWEG is available in the two rim heights 63 mm and 85 mm. The rim can be ordered in the non-disc version (rim brake) as clincher or tubular version and in the disc version, as tubeless version (FERNWEG EVO). The standard version is optionally available with a white or red label. In addition, the FERNWEG Black ED is available with a CeramicSpeed bearing, a black hub thrust piece on the front wheel and a black label.
