Ok, It's my turn to give some feed back on some "Crap" I have been using. Let's get one thing straight....the Tifosi Siff optics are NOT crap. These are one of the best pairs of shades I have wore during my endurance races and training rides. For less than $50 you get a hard case, cloth to clean them up with, and 3 sets of lenses....YES! I said 3 sets of lenses. They fit like a glove, and they look cool. Well, I think they look cool. To each their own. In the race picture to the right, under the Trans-Iowa ad shows me racing wearing these shades. Below is the specs for the shades.
- Weight: 21g
- Grilamid TR-90 - A homopolyamide nylon characterized by an extremely high alternative bending strength, remarkable toughness, exceptional resistance to chemicals, low density, and a remarkably high resistance to UV damage or breakdown. Translation - almost indestructible!
- Hydrophilic nose and earpieces - Special rubber pads designed to stress comfort but that also increases their grip when they get wet (i.e. perspiration) and resistant to aging.
- Polycarbonate Decentered Lens - Used for its high impact resistance due to elasticity, and optical clarity characteristics. The lenses flex versus shattering pon impact. Optics are further enhanced by the "decentering" which eliminates any false optical alteration (magnification, distortion, etc.).
- Glare Guard™ - Reflective coating on lenses that provides glare reduction and decreases eye fatigue.
