Aerodynamic wheelsets have traditionally forced a choice between deep profiles that slice through wind and shallower rims that handle crosswinds without drama. The Reserve 34|37 Turbulent Aero SL approaches this compromise differently, using computational fluid dynamics to optimize a moderate depth profile that performs across real-world wind angles rather than chasing wind tunnel numbers at zero yaw. The asymmetric design—34mm on the front wheel, 37mm on the rear—acknowledges that each wheel encounters airflow differently, with the front wheel seeing cleaner air and the rear operating in the turbulent wake of frame, legs, and drivetrain.

Reserve's Turbulent Aero rim shape emerged from analyzing how wheels actually perform when wind arrives at angles between five and twenty degrees, which represents the vast majority of riding conditions outside a velodrome. Rather than optimizing for the rare moments of perfectly aligned headwinds, the profile maintains attached airflow across a broader range of yaw angles, reducing the sudden instability that deeper wheels can produce in gusty conditions. The 24mm internal width accommodates tire sizes from 25mm to 32mm, with aerodynamic testing conducted using 28mm tires as the baseline rather than narrow racing rubber that few riders actually use.

The SL designation in Reserve's lineup signals their lightweight construction approach, achieved through updated layup schedules and refined carbon architecture that removes material from non-critical areas while maintaining the structural integrity required for their lifetime warranty. These SL rims shed approximately 30 grams per wheel compared to Reserve's standard depth-equivalent options, placing the complete wheelset weight competitive with dedicated climbing wheels while retaining the aerodynamic benefits of a mid-depth profile....
