chain broke 2 times!

[Zephyn.bh1]

My chain broke 2wice not even at full throttle. Should I buy a new one or just keep putting it back together each time?

A chain breaking can be a ball buster plus a long walk home. I'd find a solution and that to me would be a new chain. Unless your putting the master link on in some way not right. Some chains are more = than others. For a quality chain someone else will chime in. I've never had to replace a chain just a master link that would pop apart for some reason unknown to science.

Make sure you put your master link in from the direction of travel, that way if it ticks off the frame or guard or tensioner it won't get jilted apart.

For some reason known to science the master link will not pop off
Yes, Chainlube is correct. The round end of the master link clip goes in the direction of travel.
A common oversight when installing the master link.

Yea I think the reason was the clip was weak from taking it off and putting back on a few times. It would get snagged on the front sprockets when shifting gears.

Thanks everyone!

If you people are talking about a bicycle chain... and you think it ok, or normal, pretty much anything beside WTF to break a chain I simply do not understand. My foremost question is why would anyone use a quick-release "master link" when a bike chain tool is so easy to use? The whole idea of a chain is that it is only as strong as the weakest link. I'm sure people that sell the quick-release links will "show" you how they are Actually Stronger! or some other nonsense to sell them at $1 apiece, but using a chain tool to connect the links is obviously the best way to go. Especially when the people that it happens too, what seems to be frequently, say so themselves. Weird. It's must be a motorcycle thing, but then a motorcycle chain is built for the torque. I've never broken one of those either... thank God! Why not throw a 250cc motorcycle chain and some beefy gears on and be done with it? Another reason why being able to dial in the torque and ramp-up of the torque is so advantageous. I carry a chain with me about 80% of the time but not to replace a break but because I go through them pretty fast. It seems to be fast anyway. There is huge satisfaction to checking the chain and being able to swap it out with a new one in the middle of the ride, even more so with disc brake pads. New pads are like pulling on a pair of new gloves. The only reason I can think of to use a quick-release link is someone that has problems repairing a bike chain with the proper tool or doesn't carry one while riding.

Really?These are 415, heavy chains that stretch and wear just like any chain would and if you had the power going through it that we do than you'd know that it's not that uncommon.Motorcycle chains stretch,wear and break also and the MASTER LINK is the best way to swap out the chain,using a chain break is for exactly that removing links for fitment NOT putting it back together! The pin being pushed back through the link loses it's fit,can be misaligned and be way more hazard than the master link!People with chain line issues or excessive angles from tensioner's and such have chain wear and then breakage issues,the cheap Chinese chain quality doesn't help this any ether when putting 2-3 hp through it,not 1/3 of a hp like you!

I use a KMC brand, high-ish in their product range, light, narrow, nine speed 11/132" chain with quick links, on both the motor side and the pedalling side.

The model name.. iirc.. maybe X9.97 or something. I do check the wear occasionally as I rotate my drive-train parts anyway, buy new stuff just for my favourite and move the leftovers to my less important builds.

My chains can be removed and replaced and repaired using the quick links so I carry a few spare quick links and a few ordinary links that are tiny and virtually weightless.
The only chain tool I carry is a shoelace for the quick links. I am already wearing shoes so...


I had a 1/8" bmx chain before which had less lateral flex and whippiness, and that helped me not worry about the possibility of a derailment malfunction which is presumably the main way a broken chain incident would occur. It did require a tool of some sort to make any changes or fixes, though. I never got around to finding a master link for it but that would be good.
"The MASTER LINK is the best way to swap out the chain, using a chain break is for exactly that removing links for fitment NOT putting it back together! "

Bmx chain was about half the weight of the kit 415 chain, and now 9 speed is half the weight of that but you have to control its ability to flex laterally, IME.
I don't think that the chinakit chain has good metallurgical properties for wear resistance judging from threads on the forum.
It actually was a tiny bit rusty and it smelled like gross old metal you would find in an old man's musty tool shed when it arrived. Straight in the bin!

Can't imagine wanting to replace bike parts mid-ride.

(Yeah, that's why you check it regularly and replace it before damage can occur to the gears.) Motorcycle chains stretch,wear and break also (Same goes with motorcycle chains.) and the MASTER LINK is the best way to swap out the chain (Disagree and so do the bike mechanics that I take my bike to) ,using a chain break is for exactly that removing links for fitment NOT putting it back together! (Wrong... again) The pin being pushed back through the link loses it's fit,can be misaligned and be way more hazard than the master link! (not for anyone that knows what they are doing, and it's not hard.) People with chain line issues or excessive angles from tensioner's and such have chain wear and then breakage issues (Chain alignment is very important, more so with the use of a motor... not a washing machine motor but mid-drive),the cheap Chinese chain quality doesn't help this any ether when putting 2-3 hp through it,not 1/3 of a hp like you! (I use KMC chains but I will bow to your knowledge of cheap chains.)

So speaks a smoker.
