Race Inc. RA20-R Retro 20″ Complete Bike – Polish / Red


Race Inc. RA20-R Retro 20″ Complete Bike – Polish / Red




The baby of the family, but secretly our favorite, the RA20-R is a nod to the origins of BMX and the original frames created by Bill Bastian. The classic style incorporates a few features that increase comfort while still giving you that poppy ride we all remember from our youth.

Its 6061 T-6 aluminum frame features a classic, Race Inc., loop tail rear end and classic Race Inc. gussets combined with modern 20mm slotted dropouts. Add to that, a parts package that includes a Race Inc. chromoly fork made by Tange, and Box Three brakes and lever.

The ride of choice for those who are forever young.
