TrAsHeR Posted December 22, 2007 Report Share Posted December 22, 2007 (edited) Ok iam now building my new echo and when my backwheel is on and set up the freewheel is not lined up with the spocket so when the back wheel turns the chain crunch on the sproket ?Can the bb not be in enought ?Edit: So the anwser to my problem was to put a spacer between the freewheel and the crank but my friend told me not to because i would strip the threads, so I had to buy a pair of new cranks.I got monty cranks which a really good I would prefer not to change them and spend the least money possible. Is there any other way i could line up my chain with my sproket ?!?Thanks Edited January 4, 2008 by TrAsHeR Quote Link to comment Share on other sites More sharing options...
Dan_Trials Posted December 22, 2007 Report Share Posted December 22, 2007 Ok iam now building my new echo and when my backwheel is on and set up the freewheel is not lined up with the spocket so when the back wheel turns the chain crunch on the sproket ?Can the bb not be in enought ?Im assuming you are using either a MOD or a 116mm Stock with a FFW. In which case the BB width would be where I'd start... what's the shell width and what BB? Quote Link to comment Share on other sites More sharing options...

Dan_Trials Posted December 22, 2007 Report Share Posted December 22, 2007 Ok, if you pop the BB out it should tell you the width on the casing, it will be either 68mm or 73mm. It should also state the axle length, 125mm for example. Then you need to measure the width of the BB shell on your frame. Quote Link to comment Share on other sites More sharing options...

MOST frame's these days have a 68mm shell........ Quote Link to comment Share on other sites More sharing options...

psycholist Posted December 22, 2007 Report Share Posted December 22, 2007 The BB has reverse threads on the drive side, so it can't be installed the wrong way around. Chances are you need a different length BB axle. You may be able to fine tune it with a spacer under the freewheel, but this will only adjust the freewheel in and leave less threads to transfer the load through the chain, so less optimal.

TrAsHeR Posted December 23, 2007 Author Report Share Posted December 23, 2007 (edited) So does can someone tell me where i can get a spacer for between my freewheel and cranks ? Edited December 23, 2007 by TrAsHeR Quote Link to comment Share on other sites More sharing options...
psycholist Posted December 23, 2007 Report Share Posted December 23, 2007 Try any bike shop that's been around for a while. Any BB spacers will do the job - freewheels and BB's have the same threads, so spacers are interchangeable - most BB spacers are 2.5mm wide though. Just don't use plastic spacers...

AdamR28 Posted January 4, 2008 Report Share Posted January 4, 2008 What chain do you have? How old is it? How old are the sprockets?It may not be an alignment issue. Quote Link to comment Share on other sites More sharing options...
TrAsHeR Posted January 4, 2008 Author Report Share Posted January 4, 2008 So I have a KHE Collapse chainAnd everything is bran new and never been riden exept freewheel cranks and bb Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted January 4, 2008 Report Share Posted January 4, 2008 If you have a spare KMC stick that on instead, it will solve the problem.When brand new, the edges of the links on the Collapse chains are very 'square' and they can pop/bang on 20" bikes. The KMCs have chamfered edges on their plates and don't do this.If you carry on riding it does wear in though. Quote Link to comment Share on other sites More sharing options...
TrAsHeR Posted January 4, 2008 Author Report Share Posted January 4, 2008 (edited) Ok thanks but even if I can see that my chain is trying to go to the left and it not aligned should i still ride it ?

Ladd Posted January 4, 2008 Report Share Posted January 4, 2008 If it sounds like a crunching (sp) noise my bike did this on my 20'' echo my bb is 128 and i found that my chain was a little to tight so i took all the rear sprocket and chain off cleaned them all done regreased them and put them back on with a little looser chain and it was fine Quote Link to comment Share on other sites More sharing options...
TrAsHeR Posted January 4, 2008 Author Report Share Posted January 4, 2008 Yeah It setted up my back wheel with the right chain tension then turned the wheel and the chain got soo tight.Ill have try now with another chain and a tiny spacer.
