ritch_trialsuk Posted May 8, 2007 Report Share Posted May 8, 2007 Hi peopleI have had a good search through the forum for this problem but no joy so I wonder if anyone can help.I have bought a KHE collapse chain, absolute beast. After a serious battle to get it to work with my chain tool I fitted her on and all seemed ok. However when pedaling the chain seems to catch on the bashring presumably due to the fact it can move from side to side on my standard sprockets. I have a Leeson 660 with standard middleburn 20t front sprocket, machined down middleburn bashring and RS7 cranks. Do you need thicker sprockets to run these BMX chains? Anyone else had the problem?I also read in a post that the KHE collapse wont break, I watched Glynn (realriding) just miss a pretty meaty sidehop and landed hard on the drive side, think he landed on the chain because next sidehop bang flipped it over the front, chain gone, wat was really crazy is the chain wasnt broken, no links broken at all!!! didnt make any sense then and still doesnt lol that was with a brand new collapse. prob just unlucky, or Glynn not bothering to put the pin back in or something Any help would be ideal.Cheers allRitch Quote Link to comment Share on other sites More sharing options...
GlynnP Posted May 8, 2007 Report Share Posted May 8, 2007 I am pretty sure this should run with your standard sproket mate.Hahaha and i am pretty sure i was just unlucky ( defo put the pin back in )Just make sure you dont use the split link as they arnt as strong as they say as i also snapped that Not been to lucky with these chains.

ritch_trialsuk Posted May 8, 2007 Author Report Share Posted May 8, 2007 Definately catches on the bashring, every 2-3 pedal strokes. I was thinking of possibly putting in very thin washers between the front sprocket and the crank body? That could work and wouldnt effect the chain-line hardly at all. Until I get it sorted I am riding with my old faithful PC58 Being a Leeson rider I am used to working with 0.00001 mm's of clearence on various crucial components any other ideas?

darrenhopper Posted May 8, 2007 Report Share Posted May 8, 2007 If it's every 2 - 3 rotations of the crank it's probably the pin you used to join the chain. If this is the issue, you should be able to see one of the pins protruding fractionally further from the side-plate of the chain. I'd reckon on the outside of the chain because there's sod all to catch on up along the inside of the chain line.It may also feel a bit like a stiff link.Just shove the pin back a little with your chain tool so it looks, more or less, like all the rest.

GlynnP Posted May 8, 2007 Report Share Posted May 8, 2007 Yer mate surley if you put washers between the sproket and the bash on the bolts that join them together.Will space it just enogth to stop the problem. Quote Link to comment Share on other sites More sharing options...
Matthew_Gibson Posted May 8, 2007 Report Share Posted May 8, 2007 Which side is the split link on? it could be rubbing against the bash. Just flip it round so its on the otherside of the bash. Pain to get on and off, Pliers through the spokes and that, but could be that. OR watching on the tensioner, (depending what tensioner your using) Old mech, it will happen! Rolloff happens to them too, you need a washer to it clear. Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted May 8, 2007 Report Share Posted May 8, 2007 My mate has one of these and it did the same on his super pro bashring. It is only the chain cutting away at the bashring, tarty even said it would happen so it is nothing to worry about, ride it around until it has cut away at it enough to run smoothly.

I might file the bashring away instead to stop any damage to the chain.Which side is the split link on? it could be rubbing against the bash. Just flip it round so its on the otherside of the bash.

PaRtZ Posted May 9, 2007 Report Share Posted May 9, 2007 Yer they do but they arn't as strong as they sayDont Use themmy split link has lasted longer than a shadow conspiracy interlocker chain so im happy so far.Mines really stiffening up though with use. I took it off and it still had the shape of the rear cog lol. absolute tank of a chain though, pretty good buy for a company that specialise in flatland?
