Yes, Bola PRM 50R is designed for both gravel and road use, with 21mm or 24mm internal width options to fit 28–48mm tires and tubeless compatibility. What are the weight benefits of a 1230g carbon wheelset? At 1230g, this wheelset offers lower rotational weight for improved acceleration and less fatigue during races, matching leading ultra-light carbon models. How does the Bola 50R with blade carbon spokes compare to wheels with Sapim CX-Ray spokes? Blade carbon spokes are lighter and stiffer than Sapim CX-Ray steel spokes, offering improved power transfer and a slight increase in comfort due to carbon’s vibration damping. Is a 21mm or 24mm internal width rim suitable for 32mm tires? Yes, a 21mm inner width suits 28–32mm tires for modern road and endurance setups, while 24mm supports wider gravel tires up to 48mm. What performance benefit do blade carbon spokes provide on a 50mm carbon wheel? Blade carbon spokes increase lateral stiffness and reduce weight versus steel spokes, leading to snappier acceleration and improved stability while maintaining compliance.\",\n  \"brand\": {\n
