edd91 Posted December 12, 2006 Report Share Posted December 12, 2006 (edited) i have searched for it but i cant find anything, but i am wantingto run single speed on me stock but i dont know what size sprockets i need to run on the back, and is it better to use a conversion kit or just set it up on the cassette with a mech, or chain tensioner Edited December 12, 2006 by trials freak Quote Link to comment Share on other sites More sharing options...
echo v onza Posted December 12, 2006 Report Share Posted December 12, 2006 (edited) you shouldn't use the cassette and mech it will be very heavy and will flap around a lot scratching your frame, also it will probably not last very long before the teeth on the cassette wear away causing the chain to slip. which in the worst case scenario could cause you to have a very bad accident.the best thing to do if you have a standard 22tooth front sprocket, is to get the gusset single speed kit from tarty bikes it comes with a 16 and 18 tooth rear sprocket so you can swap them over to find whether you prefer a lower or higher gear ratio!http://www.tartybikes.co.uk/product.php?id=120 Edited December 12, 2006 by echo v onza Quote Link to comment Share on other sites More sharing options...
stitch2 Posted December 13, 2006 Report Share Posted December 13, 2006 rear sprocket depends on what is you ckranks lenth and front sprocket size. I have: 170mm, 18-16. Good enough. Cheers! Quote Link to comment Share on other sites More sharing options...
abtrials Posted December 13, 2006 Report Share Posted December 13, 2006 i think you need to tell us what you are currantly running or if you are not running any cranks at the mo then say Quote Link to comment Share on other sites More sharing options...
adam trials Posted December 13, 2006 Report Share Posted December 13, 2006 keep the current cassettes and just tighten up the derauler to the maximum so it doesnt move that is what i have done and it runs perfectly when the wheel is aligned correctly Quote Link to comment Share on other sites More sharing options...
Lawnmowerman Posted December 13, 2006 Report Share Posted December 13, 2006 22 on the front and 18 on the rear Quote Link to comment Share on other sites More sharing options...
20inchsuperstar Posted December 13, 2006 Report Share Posted December 13, 2006 i don't know what your running/how much money you have to play with/what your plans are, but i run singlespeed on my Pitbull and have an 18-16 ratio. I am running a try-all 108.9 freewheel and zoo rear hub this is my personal choice so its up to you really. as has been said before, don't use the casette as it may result in more wear to the teeth etc. if you want to get rid of the rear casette and use a single sprocket, i would recommend trying your hardest to run it bmx style, no tensioners. But if like me you cannot get the chain to join up at an appropriate point, use a chain tensioner(obviously) but mine slackens off ever so slightly so needs tightening before every ride. BMX style is by far the lighter and more reliable method so it's up to you really,Hope this has been helpful,Matt Quote Link to comment Share on other sites More sharing options...
edd91 Posted December 13, 2006 Author Report Share Posted December 13, 2006 thanks for the help guys, ill be investing in single speed kit, adam trials you run with a mech and cassette and it keeps coming of so i thought i would get some advice of people that actually run single spreed with out a cassette and mech Quote Link to comment Share on other sites More sharing options...
Rebelistic Posted December 13, 2006 Report Share Posted December 13, 2006 If you run gears at the moment then count the teeth on the cassette for your preffered gear and go for that ratio (I use 22 - 18).I'm just using a sprocket off an old cassette and some plastic spacers - seems to work ok for me, but if you get a proper single speed sprocket then it will probably have longer teeth and be less likley to skip.

Stick with your casset and mech much better. You have a choice of gearing . And most single speed sprockets dig into your hub (which you dont want). Unless you buy a good quality cog like a king kog.Matt Rushton Quote Link to comment Share on other sites More sharing options...
digo Posted December 13, 2006 Report Share Posted December 13, 2006 22-19, 175mm cranks Quote Link to comment Share on other sites More sharing options...
lankyri Posted December 14, 2006 Report Share Posted December 14, 2006 or you could try what i have done, when you was using your cassette you use 1 cog, take the whole cassette off and take out the pins remembering what cog you use, now buy some singlespeed spacers fit them, with the cog bobs your uncle you have a single speed and the gear you want.p.s. i run 165 cranks with a 20th front and a 17th rear works amazing with one small jockie wheel hope this helps mate Quote Link to comment Share on other sites More sharing options...
