Improved Bullcut Substitute: Vibration and Soundproofing Blocks (Pads) for Roller Stands and Cycle Trainers, Set of 6 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. This quietness is achieved by combining multiple materials. After much trial and error, I arrived at this combination. 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 sounds). The effect has been confirmed using a cycle trainer in an apartment building. Furthermore, when used with a cycle trainer, they allow for some lateral movement, reducing stress on the frame. This also provides a more realistic riding feel. For those concerned about the effectiveness, I'll display the measurement results in my environment (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 considered quiet, but even then, placing it directly on the flooring causes a "booming" low-frequency sound to reflect from the floor. In contrast, as is clear from the numbers, the low-frequency sound is noticeably eliminated after installing the blocks, and the only sounds are mostly the trainer and crank rotating. Although vibration measurements haven't been taken, they are 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.
