Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Didn't Scrod catch his finger a while back? I kringe at the thought, and this is why I am very careful not to put my fingers near moving chains on fixed gear bikes.

I've punctured a nail (literally the tooth went through my fingernail) while cleaning a chain once. I accidentally bumped the crankarm and the cog (not chainring) tooth went through my nail. It was a very light bump, but the amount of torque produced was enough. Any more and I would've lost the fingertip.

I've also cut open my wrist (and have 3 rather nasty scars in a funny wolverine-like pattern) from a chainring, while trying to overzealously remove a pedal in a very stupid position.

Lotsa blood both times.

Newb mistakes. Live and learn. Hope everyone is as careful as possible.

Sheldon Brown has a fairly graphic example of what can happen when you get careless with your drivetrain... a picture of a severed fingertip and the hand it came from...

Fixies are noble machines, and they need to be treated with respect.

Ekk...I've only scraped my knuckles when removing pedals before but I'm sure everyone have.

I've had my finger tip caught in the chainring once or twice...thankfully I had a really really thick rag that took most of the impact.

Funny, I had a very related experience less than 7 days ago -

Sunday morning I was at home having a quiet morning with a buddy and his 3-year old son. I went into my bedroom to get something when I heard my buddy's son scream and start crying. He's a wild child, so I thought maybe he was being disciplined.

I walked into the hall to see blood trailing all the way from the garage, through the kitchen, into the hallway bathroom. There my buddy was holding his son's fingers under the faucet. Blood everywhere. He told me what happened but I already knew.

He spun the crank on my track bike, stuck his finger in somewhere along the chain or chainwheel. Four stitches and a broken finger later, he's learned his lesson and I deal with feeling pretty awful about it all week.

Yup. Took a big chunk of my thumb right off. My thumb nail will never be the same.

I was only pedaling slow and wiping off some excess lube when the rag got caught in the cog. That dude in the video is a tool.

I've never been inclined towards fixed gear bikes, and I guess this just gives me more justification for avoiding them. The one advantage that they have is that they force one to keep pedalling, and they also "help" one pedal to some extent, so that less energy is wasted. However, I can envisage scenarios where the bike's forced pedalling action could be hazardous to one's health while riding, for example, when one is forced to maneuver very close to a curb; you can just stop pedalling a freewheel bike on a dime and keep your right pedal/crank gracefully above the curb, but the fixed gear will just force the pedal/crank to slam right down onto the curb if you are moving at any kind of speed.

Ouch.

Yes, indeed. Every year there are thousands of serious injuries reported as a result of riding FG bikes. As a result, there are bills now pending in congress to ban this dangerous activity. Thank you for providing this important public safety alert.

You can survive with sliced jugular.

He needs to use his carotid artery.

Mayhaps the scrotum, ala Swedish chainsaws... in the interest of cleaning the gene pool.

I got my thumb caught between a chain and a cog a little over a week ago. Took a chunk off. My advice, don't do it.

I did pretty much the exact same thing last Wednesday. Wiping off excess lube, rag, chain, chunk gone. What kinda down time am I looking at before it's healed up and the scab is gone Scrod?
