Hello. I am the person who often uploaded CCTV footage for winter riding.
There are many people who just ride in the winter, and many people who are preparing for competition schedules...
Many people don't know much about tire performance, bicycle geometry, air pressure, speed calculation sites, so I made this.
Rather than making a profit, I hope that many people will find it helpful and convenient. Please give me a lot of feedback.
(Especially since I made this for my own cycling life...)
