Use your existing chainring and any shimano style 8 or 9 speed hub (choose "Kit 2" from the drop down menu for 6 and 7 speed cassette hubs), and simply add the following A 4Jeri chain tensioner to take the slack out of your chain (great quality sprung tensioner, ideal for road and MTBs) A damned fine quality KMC 3/32 inch width singlespeed race chain. A Gusset spacer and cog kit with both 16t and 18t rear cogs so you can choose the gear that's right for you. This fits all 8 or 9 speed shimano style cassette hubs.

Lightweight alloy Chain cage to keep the chain on Adjustable cog position to perfect your chainline Quantity: 12345678910 Options: Please select ...silverblack Buy Now: Gusset Bachelor Single Speed Tensioner £11.99 (+ postage of £1.78) Damned tough tensioner that holds the chain in a fixed position (its not sprung like a Surly). The roller makes a slight noise when the chain rolls over it - but this is easily fixed by stretching a cross section of innertube over the roller.  Unreal value for money. Out of stock til end of Sep 2008 Quantity: 12345678910 Buy Now: 4Jeri Single Speed Tensioner £17.50 (+ postage of £1.78) Its a 4Jeri (forgery) of the classic Surly. Drilled out to save weight, its a very good bit of kit. We ahve sold loads and never had any complaints or failures. Why pay more? Ideal on road bikes as the jockey wheel is quieter than a roller. Also great offroad. Quantity: 12345678910 Buy Now: Surly Tuggnut Single Speed Tensioner £19.99 (+ postage of £0.98) Ever stomp on the pedals just to have your rear wheel slide forward in the dropouts and throw your chain? We have....using all kinds of hubs in all kinds of frames. There are lots of BMX-style tensioners out there, but few of them fit in mountainbike / track dropouts without some serious grinding. So, we decided to design a chain tensioner that will keep that rear wheel static in the dropouts...and most other kinds of rear-facing horizontal dropouts. Plus, ours will open up a bottle o' brew. What's more it makes getting perfect chain tension a breeze - spot on everytime - no need to hold the bike with one hand, pull the wheel back in another hand, and then wrench the bolts down in yet another hand (that's three hands!) Works with bolts and Quick releases. The tugnut takes the load, so you can run a QR without fear of slipage.  The body of the Tuggnut is investment cast in stainless steel for durability. It features a thumbscrew, for tool-free adjustments, and 2 axle holes for a wide range of fore/aft wheel positions. The Tuggnut comes with an aluminum adapter that reduces the axle hole from 10mm to 6mm, so you can use it with quick-release axles, in addition to nutted axles. We sell it as a single, because you really only need one...on the drive side. But, if you absolutely need one on the non-drive side of your rig, to achieve balance in your life, you are in luck...the bottle opener works either way. Buy Now: Spot Brand Rocket Single Speed Tensioner £24.99 (+ postage of £0.89) Does the same job as the Surly Tuggnut, but in rocket shape... still opens beer too. 10mm hole, for 10mm axles Sold individually, as really only need one.
