Hello, i want to convert my 2006 Specialized Hardrock Sport into a single speed. What would the easiest way to do that be? I don't want to take it into my bike shop because its pretty expensive. So thank you!

You need a suitable crankset and a White Ind. ENO eccentric hub, methinks. On the other hand, why not grab a Kona unit or similar - better value.

SS or fixed?

Ss...

you'll need to get a conversion kit. they are pretty cheap at pricepoint or nashbar. I think the chainings are pressed together on the hardrock,right? So you can't make it a single ring. If you have spare parts you can do your own ss kit with a cog some spacers and you'll need a chain tensioner for sure.The "MAGIC" ratio's don'yt always work the best.

I can't find any of the conversion kits.can you link one thanks.

Step one: Pick a gear ratio that you're comfortable with that also has a somewhat straight chainline and set the bike to that speed.

Step Two: Disconnect the shifter cables.

Step Three: Profit.



That's kind of a joke. You need to get a chain tensioner so you're RD won't shift back to the smallest/largest chainring.

assuming the hardrock has vertical dropouts your only problem is going to be achieving correct tension. once you've removed the derailleurs and the chainrings you don't need, you'll need to do away with the cassette. assuming a splined hub, you'll need a bmx cog, which you'll need to space correctly along the length of the hub for a good chainline. you can use cassette spacers or pvc pipe to do this. if at this point you cannot achieve good chain tension you'll need something like a surly singleator chain tensioner, which attaches to the rear derailleur mount. replace your chain with a bmx one, which is designed not to flex along its length, and you're good to go.

This is a kit that actually has what you need:

It's got a tensioner which will take up what slack there is in your chain once you shorten it, some cogs and spacers to replace the cassette on your rear wheel, and that is all you need.

To install this stuff, you will need some allen keys, a chain tool, a cassette lockring tool, and a chainwhip. Use the chainwhip and the lockring tool to take off the cassette lockring, and slide off the cassette. The park tools website has a great step-by-step instructional thing that tells how to do a lot of stuff like this, I highly recommend it. Then you put the spacers and a cog on the hub where the cassette was. Take off all your shifters and derailleurs. Shorten your chain with the chain tool until it's as tight as it can get around the chainring and cog you want. Then install the tensioner to take up what slack is left. Then you can ride it.
