At 28 grams, the Rivet sits among the lightest sport frames Tifosi makes. That featherweight construction comes from a half-frame design that eliminates the lower rim entirely, pairing a Grilamid TR-90 upper structure with polycarbonate lenses that handle their own structural duties. The result is a frame you genuinely forget you're wearing during long efforts, which matters when fatigue sets in and every minor irritation compounds.

The open lower edge does more than save weight. Vented lenses promote airflow across the lens surface, pushing humid air out before it condenses into fog. This matters during hard efforts when your face radiates heat, during humid conditions when ambient moisture hangs in the air, and during transitions between temperature zones like descending from a sunny climb into shaded switchbacks. The half-frame design handles all three scenarios without the sealed-in feeling that full-wrap frames create.

Hydrophilic rubber nose and ear pieces address the stability question that lightweight frames often raise. The material grips harder as perspiration builds rather than losing traction, keeping the frame positioned where you set it. Both contact points adjust independently to accommodate different face shapes, so the fit dials in precisely rather than relying on generic geometry. The 8-base wrap provides solid peripheral coverage while the lens vents maintain clear sightlines throughout.... Read More
