You would need some parts, but if you decide to go pegless and run 3/8 in the rear hear is how to do it yourself!
Besides questions on proper spindle length and crank installation, how to convert a 3/8 axle to 14mm (and vide-versa) in a Profile Mini/Madera V-2 Rear Hub is one of the most common.
We want to thanks Gary at Elite Cycle Imports (our Aussie Distro) and Bmx Ultra for putting together this dialed tutorial.
