Quarq ShockWiz

You’re certainly right about the information on determining the proper shock pressure. It’s labeling the technician a “bad mechanic” that I’m questioning.

The mechanic’s answer may have been completely correct and to the point if that’s all Trevor wanted to know—knowing his bike, its recommended pressure guidelines, combined with Trevor’s limited knowledge and experience. If Trevor asked how to determine shock pressure in general— okay, not so much. It’s a bad answer in that case. Labeling the tech as a “bad mechanic” doesn’t add any value, and it can polarize your bike-shop audience.

Troy Lee, of Troy Lee Designs, is one of the biggest proponents of electric bikes we know. Of course, he lined up and was more than willing to post for a photo.

I have been a subscriber for over 15 years. After reading somewhat balanced coverage of e-bikes in your magazine.

In your Interbike’s e-bike shootout article, you point out the dangers of trail closure if motorized vehicles are being used on trails. I believe an article that better explains the restrictions on motorized vehicles, especially on federal lands and as restricted by state and local laws, would be a very good contribution by your Mountain Bike Action and Electric Bike Action publications in keeping our trails safe and open.

I live in Steamboat Springs and ride with a group of riders from 50 to over 70 years old. We ride at a high level, perhaps not as fast as the younger guys, but it takes a commitment to put in the time to be
in shape.

Our trails and Trail Maintenance Fund are dedicated to “non-motorized use.” There is a sign at our most popular trailhead that reads “no e-bikes.” There is no gray area. If it has a motor, it is not suitable for our singletrack. E-bikes are fine for commuting, street and unpaved road use.

Help us keep our singletrack trails open for hiking, horseback riding and mountain biking.

“Trailgrams” tip of the month:

If you’ve dropped a small part in your garage and it seems lost forever, don’t give up hope. Instead, sweep the area with a shop broom, and then go through the dust pile afterwards. Often you will find the missing part in the rubble.
