Canardweb Posted May 11, 2009 Report Share Posted May 11, 2009 Hi everybody, I bought a trials bike some time ago. This bike used to have gears but my derailleur hanger broke in half so I want to get singlespeed...So I searched for a chain tensioner on internet and I found this tensioner which is directly placed on the rear base of the bike: http://www.chainreactioncycles.com/Models.aspx?ModelID=17621Official site of Kore bike components (chain reactor characteristics): http://kore-usa.com/products/chain_reactor.htmlI just wanted to know your opinion about it. Please let me know! Quote Link to comment Share on other sites More sharing options...
indianatrials Posted May 11, 2009 Report Share Posted May 11, 2009 Looks nice and would technically be able to be mounted on a mod But, i dont see how it actally tensions the chain, it looks like its more of a chain "guide". But im a noob so im probably wrong lol Quote Link to comment Share on other sites More sharing options...
bigamac Posted May 11, 2009 Report Share Posted May 11, 2009 Never seen one like that before. I had a similar idea and propossed it to a company but they never replied.Well if you buy one let people know what there like? Quote Link to comment Share on other sites More sharing options...
trials_pimp Posted May 11, 2009 Report Share Posted May 11, 2009 I used to have one of those years ago when they came out.They dont really tension the chain, they just raise the Long section on a bike with full gears to stop it rattling.Its ok, didnt really work very well when I had it. A DCD Was so much better.No good for trials, it wont offer any chain tension at all. The springs in it are pretty weak. Also the clamp will only fit over small chainstays Quote Link to comment Share on other sites More sharing options...
toyota200x Posted May 11, 2009 Report Share Posted May 11, 2009 My good friend swears by these tensioners. They work very well & are very reliable. Quote Link to comment Share on other sites More sharing options...
jambo Posted May 12, 2009 Report Share Posted May 12, 2009 would i be right in saying the are designed to be used in conjunction with a sprung tensioner to keep a better chain line and stop your chain jumping off your front ring? Quote Link to comment Share on other sites More sharing options...

maxxis26 Posted May 12, 2009 Report Share Posted May 12, 2009 (edited) i brought a similar thing from halfords years ago called a jigits designed to stop the chain from coming off the front chainring but you dont have to shorten your chainits more for downhill bikes as they need the chain lenth for the gears to work properly Edited May 12, 2009 by maxxis26 Quote Link to comment Share on other sites More sharing options...
