bent tooth?
well, it's been a while since i've ridden fixed, but tonight i finished up my latest project, utilizing the flip/flop hub on my trusty steel nishiki olympic.
and tonight i remembered why it's been so long.
that is to say, i felt a familiar uneven sensation whenever i let up on the pedaling and just let my legs feel the pedals moving beneath them. and i realized that i think one of the teeth on my rear cog is bent. it has to be, because way back when i remember thinking the problem was with my bottom bracket, my crank set, virtually everything but the only piece that survived from the old bike to this one: the rear cog.
has anyone else ever ridden with a bent tooth? i guess the only way to explain it is that it feels like on every turn of the cranks the bike sort of forgets what it's doing, only to kick in again. if i'm actively pedaling hard, i don' t notice it, only when i let up.
is this dangerous? will i be okay until i can replace it? when i do replace it, should i go with something other than the 16 teeth that make up my 48x16 gear ratio? (i live in the relatively flat climes of minneapolis)
other than that, it was great taking it around the block, and i look forward to a winter of fixed gear riding. the only thing is, you know, if i'm going to kill myself, i'd just as soon flip the wheel back to the freewheel side. the gearing is the same.

Probably the only damage it will do is cause excessive wear on the chain and not be very smooth. It's easy to fix though; just take an adjustable wrench and bend the tooth back into place.

I prefer the hammer to an adjustable wrench. I would probably just get get a new cog though, they aren't THAT expensive.

To see if your chain is okay, pull the rear wheel and bend the chain at each link. There should be little to no resistance as you bend the links with your hands.

the forgetting, is the dead space until the cog tightens to the hub again.

And if that's not it, take off your chain and spin your rear wheel. Sight along the cog. Do you see a tooth that pops out from the rest?
I would never ride like that (except to limp home or to the bike shop for a new cog). That seems like asking for a thrown chain, or a broken chain, or just to wear the chain (and my legs!) way too quickly.

yeah, i know it's not the chain, because i've been using that chain on the same bike as a SS. i'm not at home right now, but i'll check out the cog and lockring when i get there.
if i do end up replacing the cog, what is everyone's opinion on the 48x16 i've been pushing? when i went around the block last night, it seemed like maybe it'll be easy to spin out going downhill. i was thinking of maybe a smaller rear cog? but it's true, if i can get out of this without spending any money, i'll be pretty happy. i'm just that cheap.
