If you own a Bosch Nyon BUI350 display and need to mount it on a 35mm handlebar, these spacer rubbers are exactly what you need! This set comes with 4 pieces that help secure your display holder properly onto thicker handlebars. The rubber material provides a solid, vibration-dampening fit that keeps your display stable even on bumpy rides. Installation is straightforward - they slide into place between your handlebar and the display mount, creating that perfect snug fit that prevents slipping or rotating. The quality is typical Bosch - precise manufacturing and durable materials that hold up to weather and regular use. I've been using these for several months on my e-bike, and they've maintained their shape and grip perfectly, even through rain and temperature changes. If you've been struggling to get your Nyon display mounted securely on a 35mm handlebar, these inexpensive spacers solve the problem completely. They're one of those small but essential accessories that make your e-bike setup work properly. Definitely recommend if you need to adapt your Bosch display to fit larger handlebars!
