DT Swiss 350 Hubs: Proven bearing longevity and readily available service parts support a full life cycle of ownership. Frequently Asked Questions Are 38mm carbon tubular wheels suitable for both climbing and flat races? Yes. The 38mm profile combines aerodynamic benefits for flat\/rolling stages with a reduced weight (1,255g) that improves climbing response. Riders often favor this setup for mixed parcours. What is the weight advantage of tubular carbon wheels vs. clincher? This tubular model weighs ~1,255g per set, typically 100-200g less than similar-depth clincher wheelsets, enhancing acceleration and reducing fatigue over long distances. Can I use these wheels for criterium and endurance racing? Yes. The 25mm external width supports stable handling at high speeds, and the fatigue-tested carbon rim meets UCI and ISO safety standards for various race formats. What should I know about Sapim CX-Ray spokes? CX-Ray spokes offer high tensile strength and fatigue life, with a bladed profile for both aerodynamic and structural advantages; widely used in pro-level builds. How should the wheelset be maintained? Periodically check spoke tension and wheel trueness. Clean the rim brake track with isopropyl alcohol, and do not store in high-heat environments to protect carbon integrity.\",\n  \"brand\": {\n    \"@type\": \"Brand\",\n    \"name\": \"Carbon Fiber Sporting Goods\"\n  },\n  \"category\": \"Carbon Road Bike Wheelset\",\n  \"image\": [\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/bola_38mm_carbon_rim_brake_wheelset_dt350.png?v=1778484022\",\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/boladt350carbonwheelset.png?v=1778484006\",\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/bola_black_dt350_rim_brake_wheelset_87d87114-ab76-43b4-8069-7c0c062651ea.png?v=1778484831\"\n  ],\n  \"sku\": \"10\",\n  \"offers\": {\n    \"@type\": \"Offer\",\n    \"availability\": \"https:\/\/schema.org\/InStock\",\n    \"price\": \"860.00\",\n    \"priceCurrency\": \"USD\",\n    \"url\": \"https:\/\/bolacarbon.com\/products\/38mm-carbon-tubular-road-wheelset-dt-swiss-350-sapim-cx-ray-700c-25mm-wide-rim-brake\",\n    \"seller\": {\n      \"@type\": \"Organization\",\n      \"name\": \"https:\/\/bolacarbon.com\"\n    }\n  }\n}\n\u003c\/script\u003e \u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Are 38mm carbon tubular wheels suitable for both climbing and flat races?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Yes.
