38mm VS 50mm, How To Choose?
If you're unfamiliar with the term "rim depth," it simply refers to the thickness of a wheel's rim. At first glance, the difference between rims with varying depths can be difficult to discern. However, many factors can impact the quality of your ride, such as the wheel's stiffness, the number of spokes, the tension of the spokes, the air pressure in the tires, the overall weight of the wheel, and the rider's skill.
When deciding on your aero wheels, it's crucial to consider your riding conditions. A 38mm carbon rim could be a better option if you live in an area with numerous climbs. This wheel is lighter and has a more responsive feel than a 50mm depth wheelset. On the other hand, if you usually ride on straight roads and try to cover as many miles as possible, a 50mm rim would be a better fit. It's a lot stiffer and can maintain speed better. However, remember that the 50mm rim is more challenging to handle in crosswinds.
It's important to ask yourself why you want to upgrade your wheelset. Is it for racing or a better riding experience?
If you frequently participate in criteriums or races and plan to use this wheelset exclusively, you should consider its practicality. Considering factors like changes in wind and tire, you may opt for a 38mm wheelset, as it is more manageable in a wider range of conditions and offers better value in the long run.
Alternatively, you should also consider your race tactics. Should you focus on your strengths or work on your weaknesses?
In my opinion, it's best to get deeper dish wheels and go aero. If you want to be race-ready, consider buying a 50mm wheelset with an extra 38mm front wheel. If you find it too windy or don't feel confident riding the 50mm, you can easily swap in the 38mm.
However, we cannot give you a definitive answer on what wheel depth you need. Every situation is different, and you'll need to determine what you're looking for in your wheelset upgrade.
