Yes. The 40mm rim depth balances aerodynamic efficiency for paved roads with the wide 36mm profile and 30mm internal width, supporting wide tires for off-road stability. This makes the Bola PRM 40G suitable for versatile use across road, gravel, and mixed surfaces. How does a 1230g 700C carbon wheelset compare to alloy options for gravel bikes? At 1230g (excluding tape\/valves), this carbon wheelset is significantly lighter than typical alloy alternatives (commonly 1335–1500g), offering improved acceleration, climbing response, and reduced rider fatigue on long rides. What are the benefits of straight-pull blade carbon spokes on gravel wheelsets? Straight-pull blade carbon spokes lower overall wheel weight and increase lateral stiffness, improving power transfer and durability during off-road impacts compared to conventional round or steel options. Is this wheelset compatible with tubeless tires and thru-axle setups? Yes, the Bola PRM 40G is tubeless-ready and designed for modern thru-axle disc brake systems, maximizing compatibility with contemporary gravel bike designs. Will wider 36mm carbon rims improve tire stability and comfort on mixed terrain? The 36mm external and 30mm internal rim profiles offer excellent support for 38–50c gravel tires, enhancing grip and comfort by allowing lower pressures without excessive tire squirm on rough surfaces.\",\n  \"brand\": {\n    \"@type\": \"Brand\",\n    \"name\": \"Carbon Fiber Sporting Goods\"\n  },\n  \"category\": \"Carbon Gravel Disc Wheelset\",\n  \"image\": [\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/black_blade_cs_wheel.png?v=1780298570\",\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/white_blade_cs_wheel.png?v=1780298569\",\n    \"https:\/\/cdn.shopify.com\/s\/files\/1\/0634\/8492\/0062\/files\/black_blade_cs_valve.png?v=1780298569\"\n  ],\n  \"offers\": {\n    \"@type\": \"Offer\",\n    \"availability\": \"https:\/\/schema.org\/OutOfStock\",\n    \"price\": \"888.00\",\n    \"priceCurrency\": \"USD\",\n    \"url\": \"https:\/\/bolacarbon.com\/products\/bola-prm-40g-700c-carbon-gravel-disc-wheelset-40mm-deep-36mm-wide-carbon-blade-spokes-tubeless-ready-1200g\",\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\": \"Are 40mm deep carbon gravel wheels good for both road and off-road riding?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Yes.
