Every so often, someone writes an article about how
the New Trend is fixies, and someone else posts it to
RBT, and a bunch of people chorus about irresponsible
young bicycle riders ruining it for the rest of us. Then
we stick our heads out the window and yell "Would you
kids turn that crazy music down!"
I ride a fixed gear with two brakes because I (1) am an
old fart, (2) like the hoods hand position, and (3) am so
outrageously powerful that I regularly accelerate to
massive speeds where stopping with just backpressure
is awkward. That said, I understand from this article
that some twentysomethings are engaging in a pursuit of
looking fashionable at the risk of being imprudent. I'm
shocked, shocked to hear that gambling with their safety
is going on here!

In principle, if you spin a cog onto a freewheel hub, which is
what I do, you oughta have two brakes. In practice, if you
put the cog on tight enough, and have a front brake, there have
to be two failures to deprive you of all braking. I think adding
a BB lockring onto the freewheel hub is a good idea but not
really defensible on engineering grounds. The primary safety
measure is having the cog on quite tight; if the cog loosens,
the lockring is unlikely to help very much.
