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)

don't crash. it hurts.

don't crash. it hurts.

ok. so i just got a new crankset, chainring, and bottom bracket for my fixie. I got it all because there was a little bit of play in my cranks on both sides (i suppose indicating a problem with my bottom bracket). my old chainring had a guard around it, so I've never had to roll up my pantleg before. welllllllllll. last night after leaving the bar, I neglected to roll my pantleg up and after about 10 seconds I found myself on the ground with a pretty significant amount of skin missing from my hand and a ruined pair of jeans. my question involves what normally happens to a fixie when pants get caught. The play is back in my cranks and I'm certainly hoping its not another ruined bottom bracket. does that ever happen from that type of crash? is it even possible?

when pants get caught, they rip and you fall. Which seems to be exactly what you experienced.

indeed. hehe. yea i just took another look at it and it turned out my chain had lost tension somehow (not necessarily as a result of the spill). are there any good (and light) chain tensioners out there i could look into?

surly singleator is the best chain tensioner on the market i believe. you shouldnt need one if you have horizontal rear dropouts though, just get the tension on the chain and tighten the hell out of your rear axle. and roll your pants up!

You cannot use this if riding a fixed gear, this is merely for freewheel singlespeeds.

Chain tensioners do exist and MKS among others make them, they typically go around the axle and into the dropouts. I've personally had no luck with them (mine broke), chain tension is easily dealt with once you have practice.

Read http://www.sheldonbrown.com/fixed/index.html and read what he says about tensioning your rear wheel (using the "walk" technique) - once you have it in place, tighten it up so it won't move.

Oh, and it's long accepted gospel that you don't goof around with the fixed drivetrain - they can and will hurt you if you let them. Keep dangling items/clothing/laces/wires well away and you'll be better off. Hell, I used to tuck my pantlegs into my socks regardless of fixed or not, who wants grimey road-gacked chain grease all over their pants anyway?

My drivetrain destroyed a pair of my jeans too, but I got lucky and didn't fall off. It was pretty nasty, as part of the torn cloth got wrapped around the pedal somehow so I had my pants spread between the chainwheel and the pedal. Fortunately this just resulted in the rip spreading even further up and not in me being dragged off the bike. Not a fun experience at all, now I roll 'em up.

Wear cycling specific cycling shorts or cycling specific tights. Problem solved. Function before form.

Normaly I just rip a hole in my jeans, and look like a fool. Never crashed because of pants in the crank though, and never had it hurt my bike in anyway.

Find the burliest axle bolts you can find and tighten the **** out of them, you're lucky you didn't take a header.. tighten the bb cups and and crank arms again and for gods sake keep an eye on your chain tension every time you ride
