Gabe @ Echape Equipment and Race Wheel Rental, uses local shops to rent race wheels to those who want them for a day or a week. At the end of the season they sell those wheels to those who would like to own them. Check out Gabe’s site. If your local shop is not currently renting high end wheels have them contact Gabe.
