Many elite racers choose 180mm for rear wheels in TT setups. **What is the weight limit for deep-section carbon tubeless rims?** The BOLA 180mm Aero Rim is tested for riders up to 125kg, aligning with competitor standards. Always check frame and wheel manufacturer recommendations together. **Will a 28mm wide hooked tubeless rim fit my 700C racing tires?** The 28mm external and 21.5mm inner width supports 25–32mm tubeless or clincher tires for 700C racing wheels, improving rolling efficiency and stability. **Are deep aero rims worth it for improving time trial bike speed?** Deep aero rims, such as 180mm, can deliver measurable speed benefits (reduced drag and higher momentum), especially at sustained high speeds or flat race courses in time trials and triathlons. The tradeoff is increased side-wind sensitivity. ### Outstanding Aerodynamics and Design The 180mm aero carbon rim 700c by BOLA combines cutting-edge aerodynamics with robust craftsmanship. Designed with a deep 180mm rim profile and a 28mm external width paired with a 21.5mm internal width, this rim reduces drag significantly. Its hooked tubeless compatibility boosts rolling efficiency and improves tire retention under pressure, making it ideal for time trials and triathlon disciplines where speed and precision matter most. ### Lightweight and Strong Carbon Construction BOLA's deep aero carbon rim 700c uses advanced carbon fiber layup techniques to balance weight and durability.
