Although our LG1 Enduro Rims are our \"entry-level\" rim, you’ll find they\'re ahead of most \"upgrade\" rims in every way.We start with our Downhill rim and modify for enduro use. We kept the 30mm internal width, but updated the extrusion to better balance the strength and weight, giving you a rim worthy of long days in the saddle, both up and down the mountain!
