that one^
get that one.
the one thing you don't want is to drop a chain. i've been riding for three years and it happened to me for the first time ever tonight.
brakeless.
downhill.
on a two way street.
immediately before an intersection.
chain basically rotafixed itself and locked the rear wheel up. i rode it like a skid, unclipped before i stopped fully, and came to a stop in the middle of the intersection(green light thankfully) with nothing more than a panicked look on my face. i think the bike is damage free.
never again will i use a ramped chainring because it's cheap and i'm broke.
