Synchronous timing belts are lighter and more efficient than chain. Once set up, they require no tensioning or adjustment. The HTD profile is ideal for FRC applications - its deep tooth profile allows it to better handle high reversing loads, such as those found in an FRC drivetrain. Each year, more and more FRC teams make the design switch to belts and attain superior performance.

VEXpro timing pulleys are custom machined from high strength aluminum and black anodized for light weight and superior performance.
