DrEvil270183 Posted May 15, 2005 Report Share Posted May 15, 2005 im currently running 13-16 because i used to run 18-22 so its a similar feeling. but just snapped me chain (KMC) not sure ifs it due to my ratio or just unlucky. anyone else run 13-16 an have problems? i was thinking of changing to 14-16 but dont want to mess up my riding. im using 175 length cranks too Quote Link to comment Share on other sites More sharing options...
Ali C Posted May 15, 2005 Report Share Posted May 15, 2005 I am using 16-14, this is the only setup I have never had any probs with, never snapped a chain. Quote Link to comment Share on other sites More sharing options...
DrEvil270183 Posted May 15, 2005 Author Report Share Posted May 15, 2005 not sure if its my gear, or the fact that i got the chain, put it together, killed a link putting it together in a rush, added new links, then few weeks later shortened it for my ti bash :lol: Quote Link to comment Share on other sites More sharing options...
Phatmike Posted May 15, 2005 Report Share Posted May 15, 2005 Using 16:14 as appose to 16:13 won't affect chances of snapping a chain. Going from say 32:14 to 16:14 will put twice as much force on the chain. It's the front ring that makes a difference. :lol: You'll be fine in the gear you are, changing the rear won't help. Just buy a new chain. Mike. B) Quote Link to comment Share on other sites More sharing options...

colly Posted May 16, 2005 Report Share Posted May 16, 2005 Using 16:14 as appose to 16:13 won't affect chances of snapping a chain. Going from say 32:14 to 16:14 will put twice as much force on the chain. It's the front ring that makes a difference. the less teeth on the back means more force on the links, i dont how many teeth=how many links but lets just say a 11t will have 4 links on and a 16t will have 7t on this means 4 links have all the force on them compared to 7t i know most of the power comes from the front, but theres still a lot at the back thats why most chain slippages from a worn chain and sprokets happens at the back and is more likely to slip in 5th gear rather than 1st. (depending how worn each sproket is) but i know where you are coming from becasue most of the power comes from the front and problys makes 80% of the differecne :mellow: Quote Link to comment Share on other sites More sharing options...
Brian Bleech Posted May 16, 2005 Report Share Posted May 16, 2005 Timbo, hahaha you phat barsteward. Could easily be a rushed putting together of the chain known you. Plus I have found that kmc's don't like being taken apart and put together too often, as you know that one fell aprt on me :mellow: you could try the khe collapse chain from tartybikes and numerous bmx sites like alans bmx and custom riders. Its designed to be run with 9T bmx cogs and is meant to be stronger than the kool too or an interlock? Mike p.s. my lump has gone down a bit Quote Link to comment Share on other sites More sharing options...
Will Arnold Posted May 16, 2005 Report Share Posted May 16, 2005 i know this has little to do with this topic and im sorry if im hyjacking it :"> here is my question... if you had a weight of 1000kg hanging on 10 links of chain and the same weight on another chain of 15 links, which is most likely to break? or will they be just as likely as each other. bearing in mind that each link has 1000kg going through them :mellow: cheers Will Quote Link to comment Share on other sites More sharing options...

Tomm Posted May 16, 2005 Report Share Posted May 16, 2005 I might be being stupid, but how does that spring thing relate to the chain problem? Given that all the links are from the same chain, essentially k is the same. But we're not talking about stretch, we're talking about breakages. The non-science way of working it out would be to say that chains only really snap in real-world situations when they're a bit worn (i.e. there are irregularities), so they snap on a worn bit. I think it would be reasonable to assume that a smaller chain would wear faster, simply because it goes around more times. So it would snap sooner. But in theoretical terms, with a brand new chain, what would the answer be? Quote Link to comment Share on other sites More sharing options...
Tartridge Posted May 16, 2005 Report Share Posted May 16, 2005 Consider two springs placed in series with a mass on the bottom of the second. The force is the same on each of the two springs As for the wear thing, yeah, I guess a shorter chain would wear/break faster. Quote Link to comment Share on other sites More sharing options...
DrEvil270183 Posted May 16, 2005 Author Report Share Posted May 16, 2005 im going to order new chain and keep same gear, cant be bothered messing with my riding by changing to lighter gear :mellow: cheers everyone Quote Link to comment Share on other sites More sharing options...
