What is the difference between the the normal stingray and a junior? I just picked up what I believe is a very ratty sting ray project and found out that it was the junior model.
I was kind of disappointed with the sprocket being so small, I wanted to put a bigger sprocket on it for a torky wheelie filled ride but the chainstays give the small sprocket only like an inch clearance, not nearly enough for a beefy sprocket.
yup, the bottom bracket is a little lower (for smaller kids with shorter legs), you could probably bump up the length but you may end up with a pedal scraper ... at least the pedals could double as a kickstand.
as far as wheelies go though, those should wheelie pretty easy for ya set up the way they are, just not high speed wheelies
I put a crank about an inch longer than stock and the pedals scrape once in a while. Find a small cog for the back wheel. I was lucky, mine has a tiny cog on the rear wheel so it evens out
You gain clearance by flipping the sprocket so it's dished outwards. It may not be enough, or it may interfere with fender hardware at the dropouts. :|
so i'll jump on this thread...
is this the size diff on the chain guard?
here is the bike mocked up
70's ser #
Frame dimentions
seat post tube from BB tube to top............................... 12"
chain stay fom BB tube to rear of drop out...................... 14"
seat stay............................................................. 14"
over all lenth from ft. of steer tube to back of rear drop outs 31"
These are my measurements. Hope they help.
Outside of BB to top of seat tube 12"
Rear dropout to outside of BB 15"
Seat stay from dropout to seat tube 12"
Outside steer tube to outside rear dropout 32"
Hey Kenji looks good, just so you know the numbers in the serial number have nothing to do with what year it was made, its the two letters in front of the numbers that decode the month and year made
