Andy Kay Posted June 4, 2006 Report Share Posted June 4, 2006 HI, all I have been wanting to convert my trials bike to single speed but i'm too tight to pay £20 for the DMR kit and individual spacers are nearly a pound a pop. Anyway this morning I was messing about with an old cassette and got it apart to find that cassettes contain spacers so anyway I will tell you how to convert your bike to single speed for nothing.GuideParts Needed2x cassettespaintToolsLock Ring tool2.0mm allen keyScrewdriver1. Remove the cassette from your freehub using the lock ring tool2. Undo the three bolts with the 2.0mm allen key these may be rivetted in which case just pop the rivetts with the screwdriver by forcing it between the two cogs and turning it.3.You should then end up with this:4.It is the small plastic spacers which are needed you may have to repeat steps 1 and 2 with another cassette to get enough spacers.5. You can now paint the edge of the spacers which you will see. to make it look better.6. Now just assemble the spacers and the cog onto the freehub making dure that the rear sprocket is aligned with the front chain ring. Then tighten the lockring. You should now have a cool looking single speed set up like this:7. Now for your mech firstly remove your shifter and gear cable inner and outers. Then get the inner cable and trim it down so that from the metal bung onwards is just 3 inches then pull it through the cable clamp so that it lines the jockey wheel with the cassette cog.Just thought i'd share this with you as it has helped me Quote Link to comment Share on other sites More sharing options...

adamtrials Posted June 4, 2006 Report Share Posted June 4, 2006 Dosent a normal ss kit give support to the cog? im presuming the spacers are a smaller external diameter to a ss kit, so there is a chance of maybe the cog failing more easily or something?Just a thought, nice guide though.

Simpson Posted June 4, 2006 Report Share Posted June 4, 2006 it can kinda churn up the bit of the hub which the cassette fits onto but heck i run it anyway Quote Link to comment Share on other sites More sharing options...
Walleee Posted June 4, 2006 Report Share Posted June 4, 2006 What sorta rim is that you've plastered tar over? Quote Link to comment Share on other sites More sharing options...
Andy Kay Posted June 4, 2006 Author Report Share Posted June 4, 2006 There's no tar just a little bit from ages its actually a grind but you cant see it because of the angle and by the way the rim is a DX32 Quote Link to comment Share on other sites More sharing options...

MasterOfGussets Posted June 6, 2006 Report Share Posted June 6, 2006 it can kinda churn up the bit of the hub which the cassette fits onto but heck i run it anywayAll cogs will eat into the shell. Just try a Surly splined or Chris King Kog which have wider bases to dissipate pressure.Really good guide. I might go and do this to my old bike today so I can ride something while I'm waiting for my parts for my new bike. Quote Link to comment Share on other sites More sharing options...
Brian Bleech Posted June 6, 2006 Report Share Posted June 6, 2006 it can kinda churn up the bit of the hub which the cassette fits onto but heck i run it anywayWhen i did this, I used the pins that hold the cassette together and put them through the spacers and cog, so it spread the load a bit Quote Link to comment Share on other sites More sharing options...
Concussion Posted June 6, 2006 Report Share Posted June 6, 2006 Hi mate, nice guide and clearly explained, well done Q: Don't you need the smallest sprocket left on, so the lock ring .....locks against it and keeps everything together?

Clawz114 Posted June 6, 2006 Report Share Posted June 6, 2006 No, the lockring will lock against the cassette spacers so you wouldnt need any cogs if you didnt want to. Quote Link to comment Share on other sites More sharing options...
