Has anyone considered shortening the chain and removing the chain tensioner altogether? I just broke my second chain tensioner.

There are single speed, fixie and geared hub bicycles out there that don't use chain tensioners, BUT virtually all have horizontal dropouts, which allow the back wheel to be moved to set the initial chain tension, then periodically moved rearward to take up slack as the chain wears. Those who find having to adjust their mechanical disk brakes periodically a major PITA, will hate having to do this too.

I don't have a Mission but it looks to me like they have vertical dropouts (like most bikes), which won't allow the wheel position to be adjusted to compensate for chain wear so a chain tensioner or a rear derailleur (with a cage) must be used  to deal with the problem of the chain getting longer as it wears, and this approach offers another major benefit in that no periodic manual adjustments are required as the chain wears.

There are reliable chain tensioners out there, I've got thousands of miles on my tensioner equipped Rohloff geared hub bikes with zero problems (don't know if their XC can be adapted to fit a Mission): http://www.modernbike.com/product-2126250919

16 days later I received my replacement , sad thing is its the same part as the original
So i don't have much faith that it will last !!
I will do my screw mod to it, so if the pin brakes it still will get me home.
