The XM 421 is a perfect all round trail rim for those wanting a bit of extra width but who want to keep weight low and retain the option of running narrow mud tyres if required.

Strength Boost Welding Technology creates a perfectly welded join for a durable, reliable rim.

The rim bed is tubeless-ready and optimized to provide fast tyre installation, a great tyre fit and quick trouble-free tubeless setup.

Please be aware that this rim is a lightweight XM designated rim designed for trail use, those looking for a rim suitable for more gravity focused riding are advised to check out the super strong EX 471.
