"IBMXFF WORLD CHAMPIONSHIPS: FLATLAND
The iBMXff flatland world championships was one of last year’s highlights and we can’t wait to see it back at NASS in 2017. We will be bringing back Radlands but making it even bigger and better so ensure the perfect stage for the best international flatland BMXers. This really will be the best of BMX flatland right here in the UK."
