Busted! Chain Blowout



Right while I was in action. I was pushing the envelope, hard railing the curbs, navigating the cars and corners...then boom! Nothing. I looked down at the bike ike wtw, and \"chain's gone." I started laughing. People looking. I thought I completely blew the metro moment, but I blew a chain. So walking bike back two miles after that. Lol

I thought it was a belt drive for a second, those are some long shadows. I have never broken a chain before, but not for lack of trying.

Were you shifting when the chain broke, or just powering along? City riding is great, probably the closest thing to combat any of us will ever experience. When done with just the right level of animal aggression, you don't even need to think, just react.

Curious though, did you just leave the chain in the street? That would have been the macho thing to do.

Did it break at the break away pin?

I've never broken a chain. Not even on our tandems.

If you carried a chain tool, you'd just remove the remains of the broken link, reattach the chain and ride home (slowly, maybe). Easy-peasy!

I rode across the country fully loaded with a dozen other people. That represented more than 44,000 bike miles. Not one chain problem.

Time for a spare chain in the bike bag?

I can't tell from the photo, is the break where the master link mounted?

Looks like the chain is too short for that bike by about a third. Not surprising there were issues. Of course that particular chain and bike may have been for "illustrative purposes only."

I have broken a chain or two in 30 years. It's a greatly over-rated experience. One time I was climbing one of Colorado Springs' steep hills. That bike did not have high top tube; but if it did...

I used to carry a short piece of bailing wire in my seat bag, for emergency chain repairs, but never needed it.

Yeah, thatís a really interesting shot of the chain, I too also initially thought it was a belt drive.

Had you just installed that chain by any chance? Master link, or did you re-drive a pin?

I don’t think that we have had any threads about the wonders of shaft drive bicycles in a long time. No chain to break! In either meaning of the word.

When .. you shift matters ... forcing the chain to move sideways under climbing tension force
is not beneficial..


particularly now that, in order to pack in more cogs in a limited space,
the chains had to be thinner and the pins flush..

yup, under load, easier to drop the front derailer to the smaller chain ring than shift that rear derailer up to the taller gears

You can get a surge of momentum ahead , and that momentum can give you the momentary reduction of force

on the chain and that will help not blow out your chain pins ..

another option , on bike tours , is the double U turn.. cross the road , head down hill

get in the granny gear chainring , the U turn again and give the hill another go..


Reading the terrain ahead and getting prepared for the climb by getting in the rear ratio range before you need it

take advantage of the gear ratio overlaps by knowing where they are double shift

go to granny + a smaller cog , shift down further on the rear ..


Racing , you shift higher as you want to get to the top first and are willing to suffer
to gain that distance over your rivals..
