TheLeroyHUK Posted June 21, 2012 Report Share Posted June 21, 2012 (edited) ok, really really wanting a fourplay now... don't know why BUT: i dont like the tensioning system on them ( have seen one without ) so was wondering how i could make it so the chain didn' have to run a tensioner... would it need bigger sprockets? ALSO: into dj biking atm so was wondering if i could use the bike for both dirt jumping and street SO: looking forward to hearing from anyone with some question answering sorry if these are the most rediculas questions on the forum but wouldn't want to waste money and time :/ cheers liam Edited June 21, 2012 by TheLeroyHUK Quote Link to comment Share on other sites More sharing options...
TrialsIsHard Posted June 21, 2012 Report Share Posted June 21, 2012 Chain tension is about luck, people who have no tensioner have just managed to get a chain that's stretched the exact amount needed to not run a tensioner... Quote Link to comment Share on other sites More sharing options...

ALSO: into dj biking atm so was wondering if i could use the bike for both dirt jumping and street Own one myself, and I have looked into this. You should choose the size of sprokets that you want to run, then try to fit the chain; if you're lucky you may be able to get it to fit with no tensioner and no chain slack (just like Sean Watson's is, I believe he runs 16:14 though!). The chances are there will be some chain slack but try to get as little as possible and then get a single spoke and attach it somewhere at the rear of the bike (wrap it around the axle, or through holes in the frame, something like that), make sure you have at least two loops in it for springy-ness and then line it up with the chain. This should apply downward pressure on the chain, preventing slack and acting as a tensioner, whilst keeping the look of the bike clean. This will need changing after a while but not very often, say around the 3-4 month mark, especially if you take the spoke off of the chainline while not using the bike. Although this may seem odd you can see how well it works and looks in this video: [media=] On the subject of riding DJ I have tried it and wouldn't really recommend you do it, at least not regularly. I assume it would be better without rigid forks, but then it wouldn't be as nice for streety / trialsy stuff. Edit: also You can get the tension closer to what is desired by using a half-link chain Edited June 21, 2012 by onza pro series guy Quote Link to comment Share on other sites More sharing options...
TheLeroyHUK Posted June 21, 2012 Author Report Share Posted June 21, 2012 was going to use half link chain... on the dj topic, if i use some sus forks for it and a different chain setup would it be ok? love the look of the spoke lol cheers liam Quote Link to comment Share on other sites More sharing options...

But I would still be tempted to buy two separate bikes. Plus I don't know how much I'd trust a spoke tensioner for DJ. Quote Link to comment Share on other sites More sharing options...
TheLeroyHUK Posted June 21, 2012 Author Report Share Posted June 21, 2012 i'd buy every chain till i got one to fit ahaha yes i did mean gearing... i have a jump bike so i'll stick with that cheers lads! Quote Link to comment Share on other sites More sharing options...
onza pro series guy Posted June 21, 2012 Report Share Posted June 21, 2012 to be fair I'm pretty sure that every chainlink is a standard size and every half-link chain link is a standard (all be it shorter) size, so if you buy one standard and one half-link and neither work there would be no point in buying any others because it just wouldn't work.

isitafox Posted June 21, 2012 Report Share Posted June 21, 2012 If its a 2011 fourplay year you can't run 18-13 with a spoke tensioner and a hope pro 2 hub just so you know! Quote Link to comment Share on other sites More sharing options...
ooo Posted June 21, 2012 Report Share Posted June 21, 2012 if you can get it to run without a tensioner, it looks nice, vertical dropouts pissed me off for about a week, then I totally forgot and I'm happy to run a tensioner. I don't care how it works, its just fun to ride. Quote Link to comment Share on other sites More sharing options...
Echo-SL Posted June 21, 2012 Report Share Posted June 21, 2012 (edited) Yeah, sus on it might be hard for DJ, if you have very light gearing. Just letting you know. But half link and that magic ratio could work. Edited June 21, 2012 by Echo-SL Quote Link to comment Share on other sites More sharing options...
TheLeroyHUK Posted June 21, 2012 Author Report Share Posted June 21, 2012 thanks for all the help... set my heart on an inspired! should have on buy the next week cheeers liam Quote Link to comment Share on other sites More sharing options...
bing Posted June 21, 2012 Report Share Posted June 21, 2012 I've got one, run 18-12 gearing cos it's better for street. chain has a tiny bit of slack, but you could get away with no tensioner with a half link chain. Quote Link to comment Share on other sites More sharing options...
TheLeroyHUK Posted June 22, 2012 Author Report Share Posted June 22, 2012 does anyone use one for dirt jumping?? cheers for the advise... i'll be sure to try that... cheers liam Quote Link to comment Share on other sites More sharing options...
mintsauce Posted June 22, 2012 Report Share Posted June 22, 2012 does anyone use one for dirt jumping?? I run my Inspired Fourplay team with 80mm sus forks and love it for trials as well as dirt jumping and pump tracks. See: http://matt-barlow.com/matt-barlow/news/spring-dust/ The bottom bracket of an Inspired Fourplay is obviously higher than a 'traditional' dirt-jump geometry but I think if you're used to it then it's not a hindrance.

TheLeroyHUK Posted June 22, 2012 Author Report Share Posted June 22, 2012 i'm intreged by this! is everything else standard bar the forks? did you do anything to the gear ratio? cheers liam Quote Link to comment Share on other sites More sharing options...
mintsauce Posted June 25, 2012 Report Share Posted June 25, 2012 i'm intreged by this! is everything else standard bar the forks? did you do anything to the gear ratio? cheers liam I have a 22 tooth up front and then 2 cogs at the back (spaced out on a chris king single speed hub) The two cogs are 15T (trials) and 12T (skatepark, jumps etc). With the Trialtech tensioner it is a really quick and easy job to manually switch between the two gears dependent on the style of riding I am doing. Peace.

Ali C Posted June 25, 2012 Report Share Posted June 25, 2012 I've been dirt jumping, I thought it was fine with rigid to be honest. Quote Link to comment Share on other sites More sharing options...
mintsauce Posted June 25, 2012 Report Share Posted June 25, 2012 I've been dirt jumping, I thought it was fine with rigid to be honest. Absolutely. With that in mind, I should have pointed out that the reason I use sus forks is purely a consequence of having knackered ligaments in my hand. After all...
