Top bikes of Philly Bike Expo: Portus Enduro Bike

German frame builder Alex Clauss was proud to display one of the only full-suspension enduro bikes at the Philly Expo.

Here is the second of five best bike selections for singletrack from the Philly Bike Expo, the Portus Enduro Bike. German frame builder Alex Clauss has made a lot of friends between his two American exhibits to date, first at NAHBS in February 2016 and now at the Philly Bike Expo. And now he is even introducing his German friends to the U.S. market.

Notable are several components from the German company Tune, which Clauss describes as Germany’s equivalent of Paul Components in the U.S.

“They have been on the market now for 27 years, and I even worked for Tune for three years as a product designer,” he said. In fact Clauss helped design the crank that is fitted to this Portus enduro bike.

Clauss helped design the German-made Tune cranks fitted to the Portus bike.

The bike also features Tune stem, bars and headset, which features an external cup and is fitted with zero stack.

Brakes are the outstanding Direttissima by German company Trickstuff, where his friend Cornelius Kapfinger works. This brake is said by enduro-mtb.com to have such massive stopping power, it is best in the hands of the more skilled rider. Provided you’re OK with the price tag of around $ 400 an end, you’re good to go… or stop as the case may be.

Gears are a pre-production model from Box Components.

Portus Enduro Bike chain ties it all together.

Not everything on this bike is top-dollar componentry. The SR Suntour Auron fork is regarded as a middle-pack model. Clauss reckons it’s OK if you’re just out to have fun, but hard-core riders might want something a little up-market. We enjoyed the custom paint, though.

Rear suspension is a different story. Clauss mounted the RockShox Super Deluxe unit for top-drawer back end performance. This unit was pre-tuned for the bike after Clauss provided the leverage specs. Travel is 160mm front and rear.

Portus Enduro Bike suspension bits are low to the ground.

For frame tubes, Clauss selected Columbus Zona for the downtube and Reynolds 631 for the top. The seat tube is straight gauge and the stays are Dedacciai. A virtual pivot rear suspension system is built inside what looks like a scaffold, which Clauss refers to as The Tower.

The bike is intended for enduro racing. “It is a great enduro bike and will be good for serious racing,” says Clauss. It is still in the prototype phase, but with custom options the frame is expected to sell for around $ 3500.

Watch: Freeriding… With Just One Wheel

Ryan Kremsater has been riding mountain unicycles in the Pacific Northwest for a long time. Watch 12 years of stunts (and falls) in this 3 minute highlight reel. I heard that unicycling in the PNW is safer than mountain biking because grizzly bears will not eat a person riding a uni because they are scared …

Adidas Zonyk Pro eyewear review

The Zonyk Pros made all its light adjustments quietly while the fitted contact points kept it in place.

What is it

The Zonyk and Zonyk Pro lines of glasses are Adidas’ new all-out assault into the high-end active eyewear market. They are a full-frame, wide lens option that offers great peripheral and center vision. The technology claims and color options are dizzying, so we tried out a couple of models for the last two months.

We are big fans of glasses with big lenses. They just seem to work well for mountain biking. We’ve gone the goggle route many times but they are just too cumbersome for climbing and all-around riding. There’s a new crop of ‘goggle shades’ and they work marginally well but often look ridiculous. These Adidas glasses strike a good balance between performance and looks.

The size small glasses are shown here above the large sized option. Having two frame sizes ensures proper fit for narrow and wide faces.

Pros

Packed with adjustability
Lens is loaded with technology
Looks good on and off the bike
Center and peripheral vision is excellent
Two sizes and enough adjustments to fit most faces
So many color options

Cons

Premium price
Nose bridge is not the most comfortable

Glasses are shown here in low light conditions with the foam sweat guard installed.

Fit

The most impressive aspect of the Zonyk is the amount of fit options available. First, the glasses are available in two sizes, small and large to accommodate narrow/small and wide faces. We found this handy since no amount adjustability will fix a fit that is too narrow or wide for your face. Other manufacturers will often direct you to another model.

Second, two nose bridges are available, a short and a tall one that can be snapped in easily. Each nose bridge has two positions once in place, a narrow and wide to allow the nose to support the glasses properly.

Two sizes of nose bridges are shipped with the glasses.

Another cool feature is the arms have three positions, low, medium and high. These adjust the angle that the glasses rest on one’s face. But an added benefit is folks with uneven ear heights can use this feature to level out the glasses.

Finally, there is foam bar that catches sweat from the forehead. And since these affect fit of the glasses, they are removable, too.

The left arm is the high position while the right is in the low. This can compensate for uneven ear height and level out the glasses.

Technology

These glasses are loaded with lens jargon common with expensive glasses. There’s more acronyms that we had to learn about but they’re key technologies are polarized, mirror, LST and VARiO, which is a technology that allows the lenses to automatically change from light to dark tint within seconds. Light Stabilizing Technology intensifies contrasts and harmonizes light fluctuations, leading to reduced eye fatigue and improved concentration. Polarized lenses cut out moisture glare and may not be ideal for asphalt riding. But for mountain biking, they usually work well.

Mountain biking is a demanding sport when it comes to eyewear since lighting conditions change constantly when you’re riding in and out of trees. The Zonyk Pros performed very well enhancing contrast and visibility in all conditions. We were particularly impressed how they seemed to normalize low light and very bright conditions.

Off the bike, the Zonyk Pros don't look out of place at all.

Off the bike the Zonyk Pros don’t look too out of place.

Mtbr’s Take

After the initial sticker shock, these glasses did not call attention to themselves and that is a very high compliment. You want this quality in all mountain bike apparel and components but it is very hard to achieve with eyewear.

Once we made all the adjustments, these glasses performed sell in dark singletrack and very bright landscapes. And we felt okay wearing them on the drive to the trailhead, and for sipping post-ride refreshments.

The nose bridge is not the most comfortable, since they are rubber bands that don’t follow the contour of the nose. But other than that, these glasses performed extremely well. We’ll see how the foam sweat band works out as warmer weather arrives.

Weight is 35 grams for the size large glasses

Rating: 4.5 out of 5 4 Flamin' Chili Peppers
Price: Starts at $ 159 for the Zonyk, $ 209 for the Zonyk Pro
