Why do all this work
well now i can go from
Cruising
using a 52t front and 24t rear
To racing
with a 60t front and 16T rear
Without needing to alter the size of the chain
all i have to do is remove the snap ring that holds the sprocket in place
one minor issue is i need to get a 1/2 link even though it is close to lining up when swapping gears there is still some offset that is too much with an entire link added or removed
2 side notes are
A.
I found fixie style forks at a swap meet that i liked the look of better
they look more aerodynamic for racing
and have a chopper / monark spring fork look (without the spring attachment) for cruising
B.
I also have a 28 tooth mountain bike sprocket to put on the rear as well
If i ever want to run these bad boys (that i found on ebay for under 100$)
70t
while running an 18t rear
68t
while running a 16t rear
And to keep with the quick change idea then I will run the 60t chainring
with either the 28t rear for when running the 70t
or
the 24t rear when running the 68t
* as you can see the total tooth count front and rear must be equal for both cruising and racing for the quick change idea to work
60/16 = 76 and 52/24 = 76
70/18 = 88 and 60/28 = 88
68/16 = 84 and 60/24 = 84
