dk2 Posted October 8, 2012 Report Share Posted October 8, 2012 Just wondering what kinda gearing people are running on there inspired hex. Currently I'm using 22/17, but wondering if there is a perfect match so one doesnt need a chain tensioner. Quote Link to comment Share on other sites More sharing options...
clerictgm Posted October 8, 2012 Report Share Posted October 8, 2012 oh my god, selecting gear ratio to tight chain is very stupid. Quote Link to comment Share on other sites More sharing options...
dk2 Posted October 8, 2012 Author Report Share Posted October 8, 2012 Maybe....or maybe not. Depends on the objectiv. Quote Link to comment Share on other sites More sharing options...
alanczik Posted October 8, 2012 Report Share Posted October 8, 2012 what clerictgm meant to say... is that its silly to decide on a gear ratio just because it exactly tighten you're chain. finding your favorite gear is the most important thing..if it accidentally tighten you're chain so you dont need a chain tensioner thats great!!! but not the main thing also 1- the chain length changes from frame to frame..soo its hard to tell 2- the chain get loser and loser..so after a year of hard riding you will need a tension 3- some gear ratio "fill close" for example :22-18 and 18-15 .(and some say 15-13 ..) so maby one of them will get you better chain line but will fill the same ratio hope i helped. 1 Quote Link to comment Share on other sites More sharing options...
dk2 Posted October 9, 2012 Author Report Share Posted October 9, 2012 Hi in my opinion a 22/18 or 24/19 or 18/15 etc all the same. There is a few issues I'm trying to solve...my kranks are shimano xt and 22t chainring. This leaves 2-3mm of clearance for the chainring. Hence I would like a smaller one up front, but I don't think they exist... A 22/17 current setting gives minimum chain slack and gives me the option or running a home riged chain device. But I was just interrested in what other people where running. But for some reason must of you UK guys hate inspired...ride on Quote Link to comment Share on other sites More sharing options...

Luke Rainbird Posted October 9, 2012 Report Share Posted October 9, 2012 Enough to throw things out. Find a ratio that works with a stretched chain, rather than a new one. That way you can run a tensioner for a few rides 'til things bed in rather than having to deal with chain slack which sucks balls. Quote Link to comment Share on other sites More sharing options...
dk2 Posted October 9, 2012 Author Report Share Posted October 9, 2012 Im running a chain tensioner but it can only handle a certain amount of chain slack. Quote Link to comment Share on other sites More sharing options...
Paperclip Posted October 9, 2012 Report Share Posted October 9, 2012 (edited) I cheated, I filed 5mm into each drop out (towards the Bottom bracket) Then put a bolt through the bolt that holds the mech in place, and currently running a snail cam to tension my chain. Working a treat and can pretty much do this with any gearing you need, might not have to file as much depending on your ratio. Also my brake still lines up without any problems and my tyre clearance is good also. I got the Idea off a friend who has done the very same thing (only without the snail cam) on his foreplay Edit: I run 18/15 on my set-up Hope this helps Edited October 9, 2012 by Seabasss 1 Quote Link to comment Share on other sites More sharing options...

dk2 Posted October 10, 2012 Author Report Share Posted October 10, 2012 I'm using the dropout bolt hole to attach my chain device.its on the inside of the dropout, so its better protected. I assume 18/15 is with a freewheel up front? Quote Link to comment Share on other sites More sharing options...
Paperclip Posted October 10, 2012 Report Share Posted October 10, 2012 18/15 is 18/15 regardless of free wheel or rear freehub Quote Link to comment Share on other sites More sharing options...

dk2 Posted October 10, 2012 Author Report Share Posted October 10, 2012 Att Seabasss...do you have a link to a place that has 4 bolt chainrings in 18t ? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted October 10, 2012 Report Share Posted October 10, 2012 Pretty sure you can't get a 18t 4 bolt chainring. I think he was answering the question with a different perspective. You'll either have to stick to 22t (possibly 20t? I used to run one on my 5 bolt cranks years ago) or change cranks. Quote Link to comment Share on other sites More sharing options...
isitafox Posted October 10, 2012 Report Share Posted October 10, 2012 Unless your running 'burns you've got no chance I'm afraid. EDIT: By this I mean if you've got some middleburns you can get an 18t sprocket for it but any other standard 4 bolt cranks your pretty screwed. Or as below get some normal screw on trials cranks and an 18t sprocket. Quote Link to comment Share on other sites More sharing options...
Ali C Posted October 10, 2012 Report Share Posted October 10, 2012 or any trials cranks with an 18 tooth cog 1 Quote Link to comment Share on other sites More sharing options...
Paperclip Posted October 10, 2012 Report Share Posted October 10, 2012 Att Seabasss...do you have a link to a place that has 4 bolt chainrings in 18t ? My Point was not regarding your crank's, I simply meant you don't have to run a freewheel to run 18/15. My method still works regardless which of the three gear ratio's you go with and will take out the factor of chain stretch being a problem, When I get chance over the weekend if you would like I will upload some pictures of how easy it is to do. It also means my rear end on my hex is 380mm rather than 385 which I think most of the forum would prefer 1 Quote Link to comment Share on other sites More sharing options...
dk2 Posted October 10, 2012 Author Report Share Posted October 10, 2012 Att Seabasss...word.. i understant your idea. No pics are needed... Yes that's my thought as well I need nee cranks to run 18 up front.Thanks for the input's guys.... Quote Link to comment Share on other sites More sharing options...
Rebelistic Posted October 10, 2012 Report Share Posted October 10, 2012 Bit off topic but I wonder why the Inspired bikes don't have horizontal dropouts? I wish mine did. My only guess is so you could run gears but no one ever does (and it is possible to have horizontal dropouts with a mech hanger). I'd be tempted to try the filing modification on my Forplay if it meant I could loose the tensioner. Quote Link to comment Share on other sites More sharing options...

I'd be tempted to try the filing modification on my Forplay if it meant I could loose the tensioner. Vertical drop outs mean riders from all different back grounds and styles can choose which Gearing they prefer and run it with a tensioner, Being that the 18/15 gear ratio is in a minority with these frames there is no point in the change. They should make the rear end 380 mm though (Take note inspired) Also I'm pretty sure this will invalid your warranty for those who are at all bothered Edited October 10, 2012 by Seabasss Quote Link to comment Share on other sites More sharing options...
Filo Posted October 11, 2012 Report Share Posted October 11, 2012 23:16 with a new chain doesn't need a tensioner. Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted October 11, 2012 Report Share Posted October 11, 2012 23:16 with a new chain doesn't need a tensioner. But it does need big legs. 1 Quote Link to comment Share on other sites More sharing options...
