Description
The Sun MTX bicycle rim is differentiable from a motorcycle rim by only a narrow degree of purpose. It’s not the lightest bicycle rim in the marketplace, but it will hold up. It’s design harkens back to the dark days of MTB, when ambitions far exceeded bicycle frame geometry, suspension design, and generally speaking, component capability. As a stop gap, the MTX offered a simple solution. Wheels built with them overcompensated to such an extent that the net effect was an increase in the entire bike’s potential. And when all else failed out on the trail, MTX wheels would still hold true.
