Its rimless construction maximizes coverage while minimizing weight — the core equation for athletes in the saddle for hours at a time. Build your Rail XC and experience what properly configured, trail-optimized rimless eyewear actually feels like.\u003c\/p\u003e\n\u003ch3\u003eLighter Construction for Long Cross-Country Efforts\u003c\/h3\u003e\n\u003cp\u003eAt 31 grams, the Rail XC achieves a lighter weight than the standard Rail, making it well-suited for the long cross-country efforts where cumulative gear weight adds up over hours. The rimless design removes material at the lens perimeter where it contributes least to structural performance, achieving this reduction without compromising coverage or optical quality. These custom cycling rimless sunglasses disappear on your face — which is exactly the goal.\u003c\/p\u003e\n\u003ch3\u003eEngineered for Variable Trail Light\u003c\/h3\u003e\n\u003cp\u003eThe Rail XC's Fototec photochromic option is particularly well-suited for trail riding, where lighting shifts dramatically between forest shade and open exposure within the same ride. The interchangeable lens system serves riders who prefer manual tint selection for specific trail conditions or race formats. Both options deliver Tifosi's optical quality built for real-world trail environments.\u003c\/p\u003e\n\u003ch3\u003eRubberized No-Slip Fit for Technical Terrain\u003c\/h3\u003e\n\u003cp\u003eThe Rail XC's rubberized contact points provide a secure, no-slip fit that stays precise during the full range of cycling motion — from steep climbs to fast descents to technical singletrack. Grip improves with perspiration, ensuring your eyewear stays positioned at exactly the moment vision performance matters most. Reliable fit on rough terrain isn't optional — it's essential.\u003c\/p\u003e\n\u003ch3\u003eBuild Your Rail XC Custom Cycling Rimless Sunglasses\u003c\/h3\u003e\n\u003cp\u003eTifosi's custom platform gives you control over lens options, frame colors, and design details for your build.
