monkeyseemonkeydo Posted September 17, 2008 Report Share Posted September 17, 2008 Right got new trialtech cranks and got an 18t on front and going to run a 15t on rear. Not wanting to use a deralier or tensioner, Wats the best chain? to make it all work gd.You'll probably find the 15T far too spinny for streety type riding Mr Shrewsbury. I'm running 18/13 which is a bit stiff and have a 14T which is about perfect. Do you want to run without any kind of tensioner? That is you need info on half link chains?

Just want to know if anyone knows it wud work or tryed it on that bike.Ive taken off my deralier and dont want a tensioner.

cai Posted September 17, 2008 Report Share Posted September 17, 2008 As soon as the chain stretches it'll feel wank!Why not get a 74Kingz? that'll be pretty out of the way and light...Also 18:15 is a stock gearing, it'll feel far too light on a 24" - 18:13/14 should be nice!

John Shrewsbury Posted September 17, 2008 Author Report Share Posted September 17, 2008 I actually love you now John lolI know i know.Na but if i run 18t 15t, wud i need a half link or a normal chain? just trying to work it out. Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted September 17, 2008 Report Share Posted September 17, 2008 No idea. Dave should be able to tell you! Although I haven't heard many good things about any half link chains... But anyway- 18/15 will be too spinny. Look at the gearinches: Stock: 18/15 gives 31.2 gearinches (or whatever the hell it's called)24": 18/15 gives 28.8. Spinny. 18/14 will give you 30.86 which is about right and 18/13 gives 33.23 which is stiff but if you want a more BMXey/streety build is a good bet. I can still sidehop my bike nicely and backwheel high but can also get up a bit of speed when needed. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted September 17, 2008 Report Share Posted September 17, 2008 The Inspired has 385mm stays, right?I've been running 18:15 on 385mm stays and it required a half link to get tension reasonable, and then still needed a tensioner to keep it tightAnother mm or so shorter stays and it'd be doable, but I think you'll be a little stuck to do it without any form of tensioner I'm afraid I'm another one thinking it'll be far too spinny though, chuck a 14t on there and tension may be better too Quote Link to comment Share on other sites More sharing options...

But I advise against it, they will stretch quick and youll be even shiter! get a rolhoff. they are the best things in the world!! christ, who you trying to be?? Akrigg or sumit??

Just want rid of any kinder of tensioner really, Ive tryed it on my purple 24, which has (13t rear and 22t front) with a 1/2link chain and feels great.just want sumthing the same. But i want 18t 15t as its feels gd and ive always liked a light gear. Ill have a go anyway, if it dont work ill have to put deralier bk on.

Luke Rainbird Posted September 17, 2008 Report Share Posted September 17, 2008 An 18:15 ratio won't do it, but you might get lucky with a 16/20/22 ring up front perhaps Quote Link to comment Share on other sites More sharing options...

Luke Rainbird Posted September 17, 2008 Report Share Posted September 17, 2008 Ah fair enough - either way 18:15 won't run chainless without some kind of crazy stretched chain thoughGive 13/14 a try and see if it'll go though, if it does I'm sure you could get used to the more normal ratio it'd bring Quote Link to comment Share on other sites More sharing options...

spaceman Posted September 19, 2008 Report Share Posted September 19, 2008 (edited) Ghost chaintring?Since you're running 18:15, you would need a 16T or 17T cog (depending on how sag your chain is), and you wedge the cog in between the chain. Basically that cog just floats in between the chain when you pedal.I've used it once on my street bike, and it didn't drop out. Some of my friends tried it but it didn't work out well for them.I've also seen a bmx rider using this ghost chainring! And the thing was that he has horizontal dropouts and a full half-link chain! It was featured on the Decline magazine. Shorter chainstay maybe...(I would be running 18:15 on my 24'' too) Edited September 19, 2008 by spaceman Quote Link to comment Share on other sites More sharing options...

You must just get lucky with chain tension. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted September 19, 2008 Report Share Posted September 19, 2008 ...and when it was discussed here (or maybe that should be 'disgust') we came to the general conclusion that for trial use it'd be pretty lethal! Quote Link to comment Share on other sites More sharing options...
forteh Posted September 19, 2008 Report Share Posted September 19, 2008 My old zoo boa used to run perfect tension on almost 385 chainstays, had to file the front edge of the drop out by a mm and it dropped right in, no tensioner or anything Only problem was that the gearing was 20/16 which is probably why I couldnt gap very well on it :$ Mind you that might be pretty sensible gearing for a 24" Quote Link to comment Share on other sites More sharing options...
totaltrials Posted September 19, 2008 Report Share Posted September 19, 2008 It's never really going to work properly. Even if you get the chain tight, it's never going to stay like that. It'll stretch pretty quickly, enough for the chain to be too slack and ending in you ripping your hair out John. Quote Link to comment Share on other sites More sharing options...
manuel Posted September 19, 2008 Report Share Posted September 19, 2008 74 kingz upside down - job done. without it the chain will be loose and clanking around all over the show ... Quote Link to comment Share on other sites More sharing options...
toyota200x Posted September 19, 2008 Report Share Posted September 19, 2008 I almost had a perfect chain length setup on my Marino with 382cs. I think I could run it without a tensioner but it would clank around to much for my liking. 74King type tensioners are awesome when you can get the almost perfect chain length.

spaceman Posted September 20, 2008 Report Share Posted September 20, 2008 I still think horizontal dropouts are better. But then again, everything has its own problems. Quote Link to comment Share on other sites More sharing options...
