Since 2002, the Soulcraft Convert chain tensioner has set the standard for aftermarket singlespeed tensioners. Whether it’s making the podium at Singlespeed Worlds or helping you suffer at the local cross race, the Convert is the only choice for serious singlespeeders. Instead of relying on delicate springs to tension the chain, the Convert mounts solidly to your derailleur hanger and doesn’t move until you want it to. CNC’d right here in Petaluma, the Convert features a grooved urethane roller with sealed cartridge bearings for a noise free ride, and thanks to the unique Push Button quick release feature, tool-free wheel changes and flat fixes are a breeze. No bouncing chains, no zip ties, no noise, no nonsense*.
* Will work on mountain, cross, and road bikes, but not on fixed gear or full suspension bikes, which are nonsense.
Now that you’ve decided to buy a Convert, you should take a look at our complete conversion kit. It comes with everything you’ll need to convert your geared bike into a singlespeed, which saves you the hassle of tracking down all the parts! We offer mountain, cyclocross, and road kits, and all will work with 7, 8, 9, 10, or 11 speed Shimano compatible cassettes.
Note: If you have a 4 bolt crank, its always going to be 104mm BCD unless you have a Shimano FC-M960 XTR crank, then it’s a 102mm BCD, which we don’t carry.
