Introducing, the Misfit Psycles BONER singlespeed chain tensioner.

Designed and developed over an arduous twelve month period, the Misfit Psycles BONER tensioner is a trouble-free, maintenance-free, bull-free way to convert any geared bike to a singlespeed.

What is the BEST way in the WORLD to tension a chain on a single speed conversion?
By using science, witchcraft and genuine engineering.
And you're in luck because the Misfit Psycles BONER does just that.  It is the simplest and most reliable way to convert a bicycle to single speed.
The Misfit Psycles BONER design team has captured the best features of today's best selling FIXED ARM and SPRING LOADED type tensioners.
Benefits, without their inherint drawbacks.

Fixed Tensioners - are fixed in position.  This rigidity doesn't accomodate for out of round rings and cogs.  The stationary position requires that the tensioner be set for the lowest or highest point of natural tension, this creates both tight and loose points in the rotation.  Over time, the fixed arm will not be able compensate for chain 'stretch' and will require frequent adjustment.
Spring Tensioners - use a spring and arm to create chain tension.  This spring is prone to breakage and can be adversly effected by mud and other elements commonly found in mountain biking.  Springs, by nature, are most effective in their 'target zone'.  As the spring (arm) are required to push above or below this 'zone' the tensioner quickly becomes less-effective and the drive prone to skipping or binding.

The MISFIT PSYCLES BONER (and it's complicated matrix of algorithms on charts) not only provides the finer points of these chain tensioning systems, it utilizes common sense to smash the damning problems associated with them.

  • The BONER will push up or push down.
  • The BONER works with long stay or short stay designs.
  • The BONER can accomodate inboard or outboard chainlines.
  • The magic BONER material selected holds a memory greater than the finest elephants, it will not warp or fail (when installed by a sane individual with the most basic skills of comprehension).

ADJUSTABLE.  

DURABLE.

No springs means no breaking.
No rigid arms mean no tight spots.
None of the above means reduced noise.

MADE IN CANADA.
