For a long time it seemed standard 19mm rims were the only option for road wheels. That’s changed a lot in the last few years. Now we’re seeing very good rims 23mm and wider.
To some extent wide rims are a product of racing technology. A wider rim increases the roundness of the tire profile compared to the lightbulb shape on a narrower rim. When tire width closely matches rim width there is an aerodynamic advantage — aerodynamics are key for pro racers.
In many cases race-oriented technologies don’t translate to the recreational market but wide rims offer benefits everyone can appreciate. You are less likely to experience pinch flats with wider rims; the larger air volume allows for lower pressures, which can increase comfort; cornering is improved since tires experience less flop in response to lateral forces; and wide rims are typically stronger with better durability. There are downsides to consider too. You may require brake adjustment when switching between wide and narrow rims; and brake modulation may suffer.
Two excellent wide rims I have in stock at the moment are the H Plus Son Archetype and the Pacenti SL23. The choice is a matter of taste and specific application. Get in touch to see which rim is best for you. Here are some photos of a recent build using the Pacenti rim laced to White Industries hubs for singlespeed use. These are comfortable wheels that handle well and look terrific.
