Making Sense of Bicycle Tire Sizing
Front-End Shimmy, a.k.a. Speed Wobble or Death Wobble
We are super excited to host our 2nd big ride from our shop in Louisville, Colorado. Lennard has been hosting Gran Fondo's from his house for ages, but after he developed his heart arrhythmia, riding over 200 miles in a day became a non-starter. Now that he's been training on his gravel e-bike for years, he's ready to bring back the Fondo, this time, a gravel version. We had a great turn out in 2025, so let's make it bigger in 2026.

Zinn Cycles has the first production 32er full suspension bike for big and tall riders
We just finished up this new e-bike for a local Boulder woman who is about 5 feet tall. As usual, she could not find a bike that fit that was not a 60 pound hybrid clunker. She has been cycling for ages, and wanted an ebike that felt like a regular bike, not her grandmothers tricycle. So she found us and we started the process to build her dream e-bike.
