Chain skipping

patgoral's picture

Today I was out on a 20 mile ride and I found that twice while standing up to pedal at intersections from a complete stop, I would pedal down and it would be a really fast pedalstroke with no motion. i don't know if it is the chain skipping on the rear cog or if it is just because it was wet and I lost traction. My chain is properly tensioned so i don't know. Could it still be chain skip if the chain is tight?

I managed to rip some teeth

I managed to rip some teeth off my cog (twice) which led to the occasional chain slipping with no motion. you would likely notice other issues if that had happened to you though.

Thoughts

- Check your lock ring (if fixed)
- But it's probably those stop line stripes; they're really slick

I think it is my lock ring,

I think it is my lock ring, it doesn't feel like slipping because it happened to me once when skidding

yep, got it fixed. Lockring

yep, got it fixed. Lockring problems. Shouldn't the lockring stay LOCKed though? I dont know why it came loose.

tis what happens when you

tis what happens when you ride a fixie and use your legs to slow down. Especially if this is the bike you just finished. For the first few weeks it's a good idea to check the lock ring pretty much daily. Some people like locktite if yer never going to change the cog. Don't you work at a bike shop?

Yeah but I am super new to

Yeah but I am super new to the world of fixies. No one has ever brought one into the shop. I have been riding road forever and built up a fixie for fun. I think i'm going to end up using locktite because its a fixed/fixed flip flop hub so I can throw another cog on the otherside.

lockrings

lockrings are reverse-threaded, so that they actually get tighter if you use your legs to slow down, no? i thought that was the whole point of a lockring.

.

what i think happened here is you rode the bike on a freshly installed cog/lockring. if that's the case, then your legs are capable of getting that cog much tighter than your hands.

so once your legs make the cog tight, the log ring is now loose.

moral of the story: install a cog and lock ring. ride up a hill with a lock ring spanner in your pocket. stop at the top of the hill and tighten down the lock ring = problem solved. no locktite necessary.

and this:

pardon my french, but what the fuck are you talking about? just get another lock ring

Oh i was talking about

Oh i was talking about putting locktite on one side and not having to worry about being able to change my cog because I can put a different sized one on the other side. I think you're idea is better. I've been riding with it since the end of june about 30-40 miles a day and it JUST starting skipping yesterday.

Welp.

I thought you were selling that bike to stay out of the slammer?

Seriously... Spend a day or two just reading Sheldon Brown's website. No breaks or food, just learnin'. Everything you will ever need for a fixed gear setup is explained in detail. At the rate you're going it'll save your life. At that... Forget what some old guy said (rip) put at least 6 different brakes on your bike. Maybe even a Z brake. Wear a helmet, foam body suit, boots, and a really nice dress shirt. No doctor wants to piece back together some sweaty kid who isn't even wearing a gotdam nice dress shirt just because he was riding brakeless and never learned how a lockring worked. I mean, shit... at least with some nice clothes on he'll take you serious or something, right?

....

I still wouldn't use locktite. It isn't necessary. Get some hair on ya chest and tighten that thing down. I've never had a problem with my lockring slipping.

I got it tight and it seems

I got it tight and it seems to be holding up nicely now. Thanks!

Which one?

The chest hair, or the lockring?

patgoral's picture

both, but mostly the chest

I think

that unlike a lockring, using loctite on your chest hair might actually be a good idea. You should try it and post the results here. I am sure the FM community would appreciate it.

Suggestion

Don't use Loctite as a Personal Lubricant. Disassembly may damage sensitive parts.

Alex's picture

or if you do

take pictures and post them.

is obviously the right answer.
