Tifosi Dea Interchangable Glasses



Comfortable and effective on the bike, cool and stylish off the bike

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

From a female point of view, cycling specific sunglasses are often about as attractive as those modelled by Dame Edna Everage, but without the bling. It would appear to be hard to get real on the bike functionality with genuine style. Not so with these rather fetching Dea specs from Tifosi though.

Unzipping the lightweight protective hard case in which they arrive, you'd be forgiven for thinking that you might just have misread the website and accidentally ordered a pair of normal women's fashion shades. The frames (available in Gloss Wood or White options) are a face flattering, paparazzi defeating size and shape, and very wearable on or off the bike.

On the bike, they sit well with a helmet, giving no problem at all with fit. At just 30g they are light enough to be comfortably forgettable whether being worn or carried in a pocket, which can be done either in the hard case provided or the soft bag that doubles as a cleaning cloth. The Dea's aren't just a pretty face though, they are well featured for cyclists too. Vents beside the shatterproof polycarbonate lenses ensure they keep from fogging up, and they come, as standard, with a choice of three lens colours- Clear (98% Light Transmission), All Conditions Red (27% LT) and Brown with Glare Guard (18% LT) which are interchangeable. Replacement lenses are available separately, in a variety of different tints. A hydrophilic rubber compound is used on the nose bridge and on the legs at the temples to grip better in the presence of sweat.

Changing the lenses isn't the easiest task in the world, but nor is it Mensa standard. The frame materials are designed to flex more than normal sunglasses frames, and it's by flexing the edges that you pop out the lens. Popping the lens out is much easier than replacing it with a new one, and you're likely to get finger prints all over your shades when trying. I'd probably choose to replace lenses at home before a ride, or at a caf stop, rather than during a ride itself, given the likelihood of fluffing the changeover and possibly dropping a lens. That said, it's perfectly possible to take all the lens options with you instead, and the hard case has small padded slots to hold them all safely.

The colour of the tinted lenses is ideal for sunny summertime riding, and with the option available for yellow lenses, these would also work for lower light conditions and winter use. Protection levels against UV are good, and the lenses are optically good quality too, with no distortion.

Rate the product for quality of construction:

Well finished super lightweight frames and lenses.

Rate the product for performance:

Performed very well. Comfortable and effective.

Rate the product for durability:

Whilst the lightweight frame is designed to be flexible enough to easily pop replacement lenses in an out, I would have concerns about its longevity for this reason.

It would be easy to drop a lens in the process of changing it and scratch the surface on impact.

Should last perfectly well if you don't change lenses too often.

Rate the product for weight, if applicable:

Really light for a very 'normal' looking pair of sunglasses.

Rate the product for comfort, if applicable:

Comfortable even with a helmet on.

For a pair of sunglasses you can happily wear for everyday use as well as on the bike, this is a very good price.

Since 2009 she has been working as part of the review team whilst championing women's cycling on the side, most notably via two years as editor of the, sadly now defunct, UK's first and only women's cycling mag, erm, Women's Cycling.
