mem405 Posted July 20, 2011 Report Share Posted July 20, 2011 (edited) Hey guys, new member here. Been on the forums for a little bit (lurking), just picked up my first real trials bike. So I'm from Vancouver, Canada. I grew up riding DH but i want to learn some trials. So after trying on a 26" hardtail, i got frustrated by my lack of progression (it normally doesn't take me long to master something on a bike). And i went out and bought a trials specific 2004 echo pure. (pics below). I learned some good things and once i got used to the geometry of the bike i started to progress pretty good. My main problem now is the horrible chain skip i have been experiencing. I'm normally pretty mechanically inclined but its pretty hard to understand whats going on when I'm actually riding the bike. During normal riding the bike rides fine but when i give a good kick to the pedals (Wheelie or pedal kick) is when the chain skips. And its starting to become pretty bad (Ive fallen quite a few times due to this). With all that said I've seen quite a few other topics about this issue but i actually have a single wheel tensioner and cant quite solve my problem with the other solutions i have seen. Here's my bike: (with specific pictures of the tensioner and chain. if you need any more pics feel free to ask.)

isitafox Posted July 20, 2011 Report Share Posted July 20, 2011 (edited) Is that an Echo freehub on the rear?? If it is then that could be the cause of your problem as if I recall correctly they were very hit and miss as to whether they worked or not, did a quick search and came up with this thread which leads me to believe that it is the hub. If my eyes are wrong and it is a fixed hub then it'll either be the FFW skipping or not enough chain wrap, either way I'd opt to get that chain tucked up a bit higher into the stay! EDIT: Just had another look, might be worth taking your chain off and putting it back on the other way round as it looks like it's upside down. That might be playing a part in it! Very nice looking ride you got there also!! Edited July 20, 2011 by isitafox Quote Link to comment Share on other sites More sharing options...
JD™ Posted July 20, 2011 Report Share Posted July 20, 2011 I'd definitely consider running the chain on the sprocket. 1 Quote Link to comment Share on other sites More sharing options...
N.Wood Posted July 20, 2011 Report Share Posted July 20, 2011 Check: Chain line, the freehub, and that double sprocket set up going on there. I'd probably put approximately £5 on it being due to limited chain wrap though - A locked out deralier or a twin wheeled tensioner (Rohloff, trialtech, try-all) will likely sort your problems.

Cresswell_d Posted July 20, 2011 Report Share Posted July 20, 2011 (edited) The chain is the wrong way round, That why it might be skipping. Darren. Edit: a VERY quick 'shop photo. This is how it ment to look Uploaded with ImageShack.us Edited July 20, 2011 by Cresswell_d Quote Link to comment Share on other sites More sharing options...
mem405 Posted July 20, 2011 Author Report Share Posted July 20, 2011 Ill flip the chain around, totally missed that. and if my problems dont get sorted ill look for a double wheeled tensioner. Out of curiosity why do you need a tensioner? I have a cruiser bike that i made a single speed and i dont have a tensioner on it. Quote Link to comment Share on other sites More sharing options...

Very nice looking ride you got there also!! I flipped the chain around, didn't solve the problem. Still i feel better having fixed that so thank you. The my freewheel is on the front actually. its a fixed hub on the rear. How can i get the tensioner tucked higher into the chainstay while still getting more chain wrap. I think im going to go down to my LBS and see if they can break the chain for me and get it to fit perfectly. I would be so much more happy if i could just delete the darn thing.

piperfraz Posted July 21, 2011 Report Share Posted July 21, 2011 Have you realised that your chain is not on the rear sprocket? Or was that just to get a photo? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted July 21, 2011 Report Share Posted July 21, 2011 It is on the sprocket, he has two sprockets - Look at the photo. Quote Link to comment Share on other sites More sharing options...
piperfraz Posted July 21, 2011 Report Share Posted July 21, 2011 Ooops Why does he have two? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted July 21, 2011 Report Share Posted July 21, 2011 Back in the day it was fairly common to have a trials gear and a 'getting around' gear. This could be because he didnt have enough spacers or whatever. Quote Link to comment Share on other sites More sharing options...

I think the main reason you get chain skipped may be in the tensioner. Due to the picture, I found your derailleur was not parallel with gears so that chain got skipper by slanted join, normally you didn't find it, once you kicked pedals, then chain skipped. Try to tune your derailleur sprocket position or adjust derailleur hanger, or else, rasp the gear somewhere looks like hooking the chain.

Yeah i think your bang on, the tensioner is actually bent from an earlier crash. so i cant really make it line up right. I really dont like having a tensioner (Just another piece to break, it adds weight, and it never looks as clean.) The double sprocket thing is actually really useful, i use one gear to get around and one gear to actually ride trials. But im gonna go fixed chain and just delete that. i stopped using it now that i dont really commute with this bike. Just ordered myself brand new BB7 Front disc and back V-brake. Got some TNN green pads too. I also got gold braided hoses. Should look pretty sharp. Now im on the hunt for some new levers. Reccomendations?

trialin Posted July 22, 2011 Report Share Posted July 22, 2011 Now im on the hunt for some new levers. Reccomendations? nope.../ .\ I don't trust cable brakes, sometimes cable cut itself without thud so that I can get hurt badly. But onething I'm sure squeezing cable lever is really easy if you did great lub inside cable tube and on joints! Now I just believe ECHO hydro series, SL works great with baby oil~ that's truly mineral. cable levers? shimano XTR could be top choice: light, delicate also strength.
