DUKE STRADA AERA 56 \/ URSUS U-RD20 CL<\/h3>\n

From 1174 g* of optimised aero speed<\/strong>. Strada \u00c6ra 56 is our Elite carbon aero road wheelset, ideal for riders who want to ride fast for long periods without limiting aero wheels to race days only. Versatile within the aero universe, it performs as a full 56\/56 set or as a front wheel paired with a Strada \u00c6ra 65 rear, delivering excellent crosswind stability, precise steering and high efficiency on both flat and rolling terrain.<\/p>\n

Key processes & technologies:<\/strong>
\n\u2022 24 mm internal width, optimised for 28 mm tyres**
\n\u2022 \u00c6ra CFD profile: signature relief reducing drag by up to 10% vs a smooth rim, with no loss of crosswind stability
\n\u2022 SLR5: advanced layup of Toray T1100 carbon fibres and aerospace-grade resin
\n\u2022 SpokeCore: moulded spoke holes (20h and 24h) for a more homogeneous structure
\n\u2022 VFP: clearcoat-free finish, more durable and more environmentally friendly
\n\u2022 DRC: vibration filtering for increased comfort and precision
\n\u2022 Hooked \/ Tubeless Ready: optimum safety and compatibility with modern tyres<\/p>\n

Result:<\/strong><\/p>\n

Strada \u00c6ra 56 is the entry point into DUKE\u2019s optimised aero range. It bridges the gap between the versatility of Strada wheels and the pursuit of pure speed of the taller \u00c6ra profiles \u2013 a model designed to ride fast, as often as you want, not just on race day.With its 56 mm depth and signature \u00c6ra relief, developed using CFD simulation, it offers a measurable reduction in drag \u2013 up to 10% compared with a smooth rim of the same depth \u2013 while maintaining calm, predictable behavior in crosswinds. The goal: gain real aerodynamic benefit without fighting the wheel in gusts.<\/p>\n

Based on the SLR5 process \u2013 the road evolution of our benchmark SLS5 MTB technology \u2013 Strada \u00c6ra 56 combines Toray T1100 fibres, aerospace-grade resin and an ultra-precise layup to deliver a high-level balance of weight, stiffness and reliability, despite its clearly speed-oriented profile.DRC (Dynamic Response Comfort) optimises vibration damping and steering stability, for a more consistent feel at high speed and on imperfect tarmac. Moulded spoke holes (SpokeCore) guarantee a homogeneous, durable and reliable structure, whether drilled 20h or 24h.<\/p>\n

With its 24 mm internal width, Strada \u00c6ra 56 is optimised for a 28 mm tyre \u2013 the modern standard for fast road riding. This combination allows lower pressures, improved comfort and grip, while maintaining very high rolling efficiency. As a complete wheelset or in an \u00c6ra 56 front \/ \u00c6ra 65 rear configuration, Strada \u00c6ra 56 is designed for riders who want to enjoy the benefits of optimized aerodynamics every day \u2013 a fast, stable and genuinely usable aero wheelset, built for real-world speed, not just the lab.<\/p>\n

Crash replacement<\/h3>\n

We offer a crash replacement programme for carbon wheels. In case of accidents or heavy falls, violent shocks can damage your rim and make it impossible to use. With our Crash Replacement offer we offer you a service that allows you to replace your rim under special conditions: You get a 50 percent discount on the price of UD carbon & 3k Carbon rim, as well as the parts and the disassembly\/reassembly. This offer<\/p>\n

In the event of an accident or at-fault incident, we offer to replace your carbon rim at a preferential rate :
\n-50% off the price of a DUKE SLS or SLR carbon rim<\/strong>, plus labor
\n-50% off the price of a DUKE 3K carbon rim<\/strong>, plus labor.
\n-30% off the price of a BARON carbon rim<\/strong>, plus labor.<\/p>\n

This Crash Replacement service is valid for life, at no extra charge, regardless of the owner’s rank. The seller of used wheels can transfer this Crash Replacement service to the buyer (it’s a selling point \ud83d\ude0a). Wheels bought second-hand can therefore benefit from Crash Replacement. \u00a0Shipping costs are not included.<\/p>\n
