The 120mm deep rim reduces aerodynamic drag, optimizing speed for flat time trial and triathlon courses, especially at high speeds above 40 km\/h. However, it may be more susceptible to crosswind forces than shallower rims. Is this 28mm wide hooked tubeless rim compatible with 700x25c and 700x28c tires? Yes, the 28mm outer and 21.5mm inner width supports both 700x25c and 700x28c tubeless or clincher tires, offering modern tire compatibility. How does a 120mm deep-section rim compare to an 88mm rim for aerodynamics? The 120mm rim offers superior aerodynamic performance at sustained high speeds and in straight-line conditions, while the 88mm rim offers more crosswind stability and is better suited for mixed terrain or variable weather. What is the maximum rider weight supported by this rim? The BOLA 120mm aero carbon rim is rated for riders up to 125kg, verified by in-house and ETRTO tubeless-ready test protocols. Are hooked tubeless aero rims better for high-pressure road racing tires? Hooked tubeless designs are preferred for safely running higher-pressure (100–125 psi) road tires, providing secure tire retention and broader tire compatibility than hookless alternatives.\",\n  \"brand\": {\n    \"@type\": \"Brand\",\n    \"name\": \"Carbon Fiber Sporting Goods\"\n  },\n  \"category\": \"Carbon Road Bicycle Rim\",\n  \"image\": [\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/120tr28.png?v=1779097155\",\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/120c28.png?v=1779239625\"\n  ],\n  \"offers\": {\n    \"@type\": \"Offer\",\n    \"availability\": \"https:\/\/schema.org\/OutOfStock\",\n    \"price\": \"300.00\",\n    \"priceCurrency\": \"USD\",\n    \"url\": \"https:\/\/bolacarbon.com\/products\/bola-120mm-aero-carbon-rim-700c-hooked-tubeless-28mm-21mm-tt-triathlon\",\n    \"seller\": {\n      \"@type\": \"Organization\",\n      \"name\": \"https:\/\/bolacarbon.com\"\n    }\n  }\n}\n\u003c\/script\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What are the benefits of a 120mm deep aero rim for triathlon and time trial?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"The 120mm deep rim reduces aerodynamic drag, optimizing speed for flat time trial and triathlon courses, especially at high speeds above 40 km\/h.
