As a rider that pushes hardtails to their limit and crashes, I bend a lot of wheels. So to save money i bought a truing stand to bend them back. Since my bike repair book isn’t very clear on how to bend them back, I took an old rim of mine that i don’t use and played with it. after three days of hard work I final trued it! I still got four more wheels to true but with my newly acquired knowledge it will take me no more than an hour.
