Jim’s Tech Talk

By Jim Langley

A few weeks back in our coverage of the early season shows, including The Sea Otter, I wrote about the growing interest in and use of 32-inch wheels, a relatively new wheel size. In my comments I mentioned that Zinn Cycles was one of the companies using 32-inch wheels.

After that article, Jan Heine on his René Herse bike company blog published his thoughts on 32-inch wheels based on their testing. You can find that here: 32″ Wheel Momentum: Are Heavier Wheels Better?

Reading Jan’s take on it gave me the idea to reach out to Lennard Zinn at Zinn Cycles since I had mentioned his 32-inch wheels bikes in my piece and also because he’s a fellow mechanic, journalist and friend. Read more.

Buzz Bomb: Worth a Try If You’re Trying for ‘Smooth Energy, Mile After Mile’

By Kevin Kolodziejski

Six hours 44 minutes and 22 seconds.

Let’s say that’s the time you decide to shoot for in your first attempt at what’s often seen as the recreational rider’s 100-mile rite of passage, the century. CyclingLevel.com calls that time a “good” one and the average one for all ages and genders. So it becomes your goal time — even though the pace you’ve been keeping since you started doing the local weekly club ride suggests you’re probably better than average.
