Be careful around disc brakes (PICS NOT FOR FAINT OF HEART)

According to their blog, Tim at On-One chopped off the tip of his index finger messing around with his brakes, but is managing to keep chipper about the entire ordeal.
So,kids,the lesson of the day is to keep your fingers clear of moving bike parts.

The pics are horrific, so don't scroll down if you're squeamish.

remember the fixed gear guy that caught a finger between the chain the the cog while cleaning his bike? I dare say it was a worse injury.

I've seen a few fixie mangles and some pics of fingertips that were chewed off. It looks like the disc chop is much cleaner.

It's a reason to require chamfering the edges of disc rotors. The far more common injury seems to be cutting off the tip of your dogs tail. I think I'm going to take the an angle grinder to my rotors now.

I've cut into the tip of my finger, but I've never lopped it off ..... yet. Those are some pretty nasty pix, and perhaps part of tonight's nightmare. Ouch!

i think it's photoshopped. I doubt this can happen unless the guy was on a trainer and paddeled reallllly fast and then he put his finger in the rotor.

i am of the school of thought that the slower moving parts are moving means the worse the damage inflicted... and you get to think about it and/or see it while it's happening... coming from personal experience...

and thinking back to when i was a kid, the worst skateboard accidents always happend when you were crawling along at the speed of snail.

hope he kept the fingertip for replacement.

be careful out there!

That only makes the rotor sharper, like a new or freshly resharpened knife.

Nah, think about it. At the hub you have all the inertia of the fat tire/tube/rim/nipples/spokes moving with a large leverage arm. Coupled with the relatively thin cross-secion of a rotor, the disc becomes a serious finger chopper.

Depends on your technique. If you put the sharp edge directly on the grinder, it won't be sharp any more.

What the heck are you guys doing with your fingers so close to a spining rotors? Don't stick your hand down the garbage disposal if it's jammed either unless it's unplugged.

I did that when I was younger on a BMX bike with an overtightened chain. Didn't take off the tip of my finger, but it was close! It wasn't a freewheel either, so I had to go all the way around...

Just guessing, but if that rotor catches a finger while spinning and the hand gets stopped by the frame opening. It is an instant guillotine in disguise that people forget about till it happens

My thoughts exactly. Put you finger in the holes and spin the wheel?

Wow...that's not photoshopped, or if it was, it was an amazing job...that wrinkling on the second photo is what happens after having a bandage on for a few days.

Looks like it just missed the bone. I almost did something like that once, but with a knife. Could have been a lot worse, but, how on Earth does that happen accidentally? I'd be curious to see how that healed.
