Surly Tuggnut Tensioner
Description
Surly decided to design a chain tensioner that will keep that rear wheel static in Surly dropouts...and most other kinds of rear-facing horizontal dropouts. Plus will open up a bottle o' brew!
- Body 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.
- 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.
- Sold 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.

Want to build a single speed without having to buy a dedicated frame? Try the Melvin. The Melvin bolts to the frame where the rear derailleur would normally go and allows the use of a single speed rear wheel on bikes with vertical dropouts.
The Melvin uses two pulleys, just like a rear derailleur, which gives it 20 teeth of chain wrap. This means that the Melvin will work with multiple front chain rings while maintaining proper chain tension. Of course this is no longer a true single speed, but can come in handy when two or three gears are all you need. Twenty teeth of chain wrap means that chain rings with a maximum difference of twenty teeth can be used up front.
Chain tension is optimized when the chain length is cut so that the pulleys are aligned vertically. For 1/8" cogs Paul recommend the silver SRAM PC-1 chain and any 8 speed chain for 3/32" cogs.$312.00 (RRP)$378.00 (RRP)$312.00 (RRP)$312.00 (RRP) -

The Chain Keeper is a guide to keep your chain right where it belongs. Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chain ring and prevents it from skipping off.
Note: This is not designed for downhill, freeride, or big hit use.$207.00 (RRP)$207.00 (RRP)$273.00 (RRP)$207.00 (RRP)$207.00 (RRP)$207.00 (RRP)$207.00 (RRP)$273.00 (RRP)$207.00 (RRP)$207.00 (RRP)$207.00 (RRP)$207.00 (RRP)$273.00 (RRP)$207.00 (RRP)
