AVIIAV Aldo $3500 Korean Wheelset Review
Introduction
After two and a half years of use, I’ve conducted an in-depth analysis of the $3500 Aviav Aldo bike wheels. These South Korean-manufactured wheels represent a departure from the more common Chinese origin for such components.
Initial Observations and Durability:
Despite the premium price point, the wheels exhibit some cosmetic wear, specifically stone chips around the rim periphery. Mechanically, however, they have proven to be durable over the test period. The spokes, which I believe are sourced from the Taiwanese company Stren, and the externally located nipples (allowing for potential on-the-fly adjustments, though none were required) have performed reliably. A notable characteristic is the significantly loud rear hub.
Design and Construction Analysis:
Examining the design, I observed that the rear wheel bearing is set deeper compared to some competitor offerings. The rims feature a lacquered Aviav logo sticker and an etched Ansys logo, indicating the application of Computational Fluid Dynamics (CFD) in their design process. These wheels also incorporate “Chevron Kammtail Technology,” evident in their wavy rim profile. This design aims to manage airflow and vortices through a constant chord length, flat sections, and varying taper lengths – a distinct implementation of a wavy rim concept I have not seen elsewhere.
Front Wheel Imbalance:
A significant issue I encountered was a speed wobble that developed in the front wheel during a descent. Upon internal inspection using an endoscope, I discovered an uneven distribution of white residue within the rim, likely a byproduct of the molding process, which I believe is the cause of the imbalance. In contrast, the interior of the rear wheel was clean.
Weight and Aerodynamic Considerations:
My measurements recorded the front wheel weight at 697g and the rear at 827g. In my assessment, this isn’t particularly lightweight by current standards. Referencing data from Oz Cycle’s review, these wheels reportedly perform well in crosswind conditions. My technical analysis highlights the substantial out-of-balance issue present in the front wheel, although the tension and run-out figures were within acceptable limits. I also noted a potential connection between the hub design and H Works.
Conclusion:
In conclusion, the out-of-balance issue on a wheelset at this price point is a concern, although it may be an isolated manufacturing defect. I found the aerodynamic performance to be effective within a limited range, and the weight to be unremarkable. While the paint finish and carbon layup appear to be of good quality.
