All aluminum frame, sealed hubs and BB, premium components, 1 3/8 wheels, great geometry for a smaller BMX'er. Beefy welds throughout the frame

The dropouts could be "boxed out" for strength, welds are kinda skimpy. 165mm cranks should be replaced by 175's, 177mm for more torque. We've replaced the 42-16, 165mm orig set-up, with a 43-16 177mm and my 9 year old was blazing out of the gate. Top tube just a little shy 19"

Great bike for the price. An experienced rider would opt for a Redline, GT/Powerlite, Crupi, These are great bikes but much higher priced and some are frame/fork only. Good luck if you could find a GT expert! We weren't sure if our son would stick with the sport of BMX, so far so good, and he still has a good bike to remain competitive, and i'm not out of 5,6,$700 bucks.

The RMJR is great bike part for part as compared to the popular brands. Also, it is fully loaded with nice components for about 30% less.

Keep on strokin' (dig, dig, dig, dig)
