The ENVE 4.5 features uncompromised aerodynamics, stability, lateral stiffness, braking, and cornering prowess.
An evolution of our patented SES rim shape makes the SES 4.5 a dream wheelset for the performance driven road cyclist and triathlete. The SES 4.5 features uncompromised aerodynamics, stability, lateral stiffness, braking, and cornering prowess. The SES 4.5 is extremely stable, making it the optimal choice for cyclists seeking confidence inspiring aero performance on the windiest of days.
The SES 4.5 maintains all of the same foundational technologies of the Smart ENVE System wheel line which include in-frame aero development, asymmetrical rim geometries, and moulded texture braking surfaces. The front rim is 27mm wide and 48mm deep while the rear is 27mm wide and 56mm deep. Rim weights (tubs) 360g + 399g (clincher) 470g + 490g.
Strada says – we have been impressed by the quality of finish on all the ENVE rims. There is no touching up or hiding with these – the rim is just smoothed and polished matt UD carbon. They handle spoke tension well and are very clean inside with no remnants of the moulding process left behind. Having met and spoken to ENVE engineers at length we remain convinced ENVE are making some of the best rims on the market today. The ENVE 4.5 will handle a cross wind very well and a local 64 kg customer has ridden his 6.7s all winter with no issues. The 5 year rim warranty is class leading and only ENVE mould the spoke holes into the rim which can withstand 700lbs of pull before failure. The rim width means a comfortable ride and good handling – all in all the Smart ENVE system 4.5 are a great rim to work with and ride on.
Here is our own 3 min video review of the ENVE 4.5 wheelset –
INTRODUCING THE SMART ENVE SYSTEM – the recipe for a fast wheel is no one single element; rather, it’s a combination of factors. When you start with in-frame development and blend proven aerodynamics, optimised stability, lightweight, stiffness and durability, the result is a revolutionary wheel design.
SPEED – The Smart ENVE System optimizes the interface between the frame surfaces and the wheels, creating an integrated system. The front and rear wheels interact differently with the air and the rest of the bicycle. Rim shapes are optimized to allow airflow to stay attached at higher yaw angles, thus reducing drag and improving ride performance. The front wheel is wider and shallower to improve stability and reduce drag in any wind condition. The rear wheel is deeper to reduce drag where stability is less affected. Wheels were tested on multiple frame designs in order to produce the maximum drag reduction. The result is a wheel system, which handles predictably, and displays superior drag results when installed in multiple bicycle frame designs.
STABILITY – Steering feedback in variable conditions needs to be predictable to have total handling confidence. Less predictable wheels have a non-linear steering response, resulting in erratic and unpredictable handling in unsteady conditions. The shape of the ENVE 4.5 rim is optimised to ensure even and predictable airflow attachment. What the rider experiences is a balanced build up of side force as the angle of crosswind changes. This allows the rider to accurately predict the handling mannerisms of the wheel and avoid dangerous over correction cycles. The focus on steering stability resulted in improved handling and confidence in varying crosswinds. Therefore, the wheel shape was optimised to produce a predictable and linear response.
STRONG, STIFF, LIGHT – THE ENVE PROCESS
ENVE is renowned for developing the strongest, stiffest and lightest rims on the market. This durability is proven across all disciplines of the sport including being the first and only carbon wheel to podium at World Cup DH events. All ENVE products, including the Smart ENVE System, share this advanced manufacturing technology. These technologies involve:
Highest strength to weight ratio in the industry.
Proprietary moulded in spoke hole technology.
Textured braking surface allowing for a more positive engagement and better braking in wet conditions using the supplied brake pads.
Jason at ENVE says – “We want to create only the best. ENVE is a zero compromise company.”
