Super-wide hoops for gravel: ENVE launches M525 G

25mm internal rim width handles gravel tires from 32mm on up

As gravel tires continue to explode in variety and selection, American carbon brand ENVE just launched the M525 G wheelset, which features a massive 25mm internal rim width laced onto disc road bike hubs. 

The M525 is ENVE's new cross-country mountain bike rim, and it now comes with road compatible hub options.

In testing with mountain bike tires, ENVE claims that its 'wide hookless bead' design reduces pinch flats by more than 60%. For gravel — where flat tires are all too common — ENVE claims that its M525 design will help out similarly.
