Making Sense of Bicycle Tire Sizing
Front-End Shimmy, a.k.a. Speed Wobble or Death Wobble
The Zinn Fondo* returns this year as a gravel ride on the summer solstice. This year it will start and finish at the Zinn Cycles shop in Louisville. Riders can choose one of three loops of approximately 60km, 85km, and 100km in length. There will be a ride leader for each loop. All three loops will be primarily on bike paths and dirt roads. The “Corto” (short loop) goes up Chapman Dr. and down Flagstaff Rd. The “Medio” (medium loop) goes up to Gold Hill via Fourmile Canyon Dr. and Gold Run Dr. and returns via Sunshine Canyon Dr. The “Lungo” (long loop) follows the Medio loop with the addition of turning left at Salina to continue along Fourmile Creek to Pennsylvania Gulch and up Switzerland Trail to Gold Hill Rd., rejoining the Medio loop at the Gold Hill Store.
Preventing Seatpost slippage
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.
