The 2021 Radio Bikes Quartz line of BMX race bikes is pretty sick! It’s the brands top of the line race completes and they feature a lower profile, disk brakes, carbon forks, nice graphics and more! The bottom bracket height is slightly higher than the average race bike at 11.6″. it also has internal chain tensioers and it comes with v-brake mounts. The one featured here is the XXL(21.75″tt) model but it also comes in Pro L(20.9″tt) and XL(21.25″tt) sizes. Be sure to give it a rating below for the 2021 Top BMX Race Bikes chart
