Vibration and Soundproofing Blocks for Roller Stands and Cycle Trainers - Improved Version, Set of 8 I've created these blocks to prevent vibrations and noise when using indoor cycling training equipment (roller stands, cycle trainers, etc.). They measure (width) 60mm x (depth) 60mm x (height) 38mm, the perfect size for placing the equipment's legs. While NR urethane rubber alone provided sufficient effect, I've added vibration-absorbing rubber to the top this time, making them even quieter. The combination of multiple materials achieves quietness. This combination is the result of trial and error. The vibration-absorbing rubber absorbs large-wavelength vibrations, while the sponge rubber evenly distributes the load and absorbs small vibrations and sounds (such as low-frequency noise). The effect has been confirmed using a cycle trainer in an apartment building. Also, when used with a cycle trainer, they allow for some lateral movement, which reduces the load on the frame. This also provides a more realistic riding feel. I'll show the measurement results in my environment, as some people may be concerned about the effectiveness (see image 4). Measurement Environment ・Flooring: Flooring ・Trainer: CYCLOTRON FLUID ST ・Tire: Zaffiro Pro Home Trainer Tire Results Average before installation: 72.75db (noisy office, vacuum cleaner) Average after block installation: 57.25db (office, normal indoor conversation) The combination of CYCLOTRON FLUID ST and home trainer tires is already quiet, but even then, a "booming" low-frequency sound reflects from the floor when placed directly on the flooring. In contrast, as is clear from the numbers, the low-frequency noise is noticeably eliminated after installing the blocks, and the sound is almost entirely just the trainer and crank rotating. Although vibration measurements haven't been taken, it's clearly shut down. I've received comments from previous buyers such as "I was allowed to use Zwift at night" and "I confirmed the effect even with a direct drive trainer," and I believe everyone will be able to experience this effect.
