Tifosi Radius FC Sunglasses



Well designed glasses with crystal clear optics and a comfortable fit

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.

Good scores are more common than bad, because fortunately good products are more common than bad.

With looks that don't shout 'cyclist', the Radius FC sunglasses from Tifosi make for great all-rounders, but that doesn't mean a sacrifice on the bike. With their crystal clear optics and a comfortable fit, you can wear them for hours.

Based around a Grilamid TR-90 nylon frame, the FCs weigh a mere 24g with the lenses in place, and thanks to the qualities of the material they are hugely flexible and hard wearing. Ideal if you tend to forget they're in your pocket when you sit down...

This flexibility also means they fit plenty of head sizes without applying heaps of pressure. In fact comfort is one of the biggest selling points of the Radius. The flexible rubber nose and arm grippers are hydrophilic, which means they grip more the wetter they get – so they won't slip down your nose when the going gets sweaty.

The lenses themselves are made from polycarbonate, which is tough and used in the majority of eyewear thanks to its ability to shrug off scratches and not shatter should it break, firing hundreds of shards into your eyeballs.

In the zipped case you get a choice of three lenses for varying light conditions. The Clarion Blue are for sunny days, allowing 14.7% of light transmission, the AC Red 41.4% for increasing contrast on dull days, and the Clear, which allow nearly all the light through. All offer 100% UV protection.

All three lenses offer a large viewing range thanks to the lack of frame, with no distortion. Small vents on the outer edge of each lens stop them from fogging up and allow some cool air through. It's directed away from the eye, so pollen and the like shouldn't affect you.

Swapping the lenses is a 30-second job: pull the lens away from the nose section to allow the deeper profiled arm end to drop out. Refitting is the opposite.

These are really good glasses that perform well in terms of optics and, just as importantly, comfort. The arms provide plenty of grip without any pressure points, plus their narrow profile means they fit with every helmet I've tried.

Some may baulk at the £69.99 price but I think they represent decent value for money. The fit, weight and optics make them ideal for a multitude of sports too, not just cycling.

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
