Description: GT Bump BMX Bike 20in
The GT Bump BMX Bike is has everything you need to hop on and get down at the park and trails or just rip around the streets. It features a chromoly main frame and a downtube gusset for extra strength. The GT 3-piece crankset is full chromoly and has a sealed bottom bracket. The wheels are sweet, featuring fully sealed hubs and a 9T driver on the rear cassette. Tektro U-brakes are there for quick stops, but once you are on this bike, you won't want to.
NOTE: All bikes are sold and delivered partially assembled. Final assembly should be done by a certified bike technician. Failure to have the bike assembled by a certified bike technician may void the warranty and could result in damage and/or injury if not assembled correctly.
I agree. The difference will not be huge... although for the record, GT suggests that the 20.5 would be the optimal choice. I recommend you chat with our bike guys to make sure you get your BF the perfect bike. Cool present! 1 (800) 409-7669
Spec wise both of these GT Bumps are going to be quite similar. The Bump listed here is the 2013 model, and the 309 option is the 2014 model. Both are a fantastic choices. Let me know if have other concerns!
