Diverging from their road-going ancestors, gravel bikes offer a choice of wheel sizes: the standard 700c as seen on road bikes, or slightly smaller 650b – with many gravel frames designed to be able to accommodate both. You can often choose between these gravel wheel sizes when ordering your new gravel bike setup, too.

Are gravel wheels different to road wheels?
Yes, you can ride a normal road wheel on gravel, but the main difference is in the internal rim width. Gravel wheels are wider than road wheels to better support a wider tire. While most road wheels have internal rim widths in the 17-21mm range, dedicated gravel wheels are usually about 20-25mm.
