Yess Labs hooked us up with their revolutionary new chain tensioner. How can a tensioner be revolutionary you ask?
Well, check it out.
This is the old System:Old System
What this system did was apply pressure to the top side of the chain, as you can see, and it was positioned at the rear drop out. This means, when the bike goes through it's suspension, the chain grows, but the tensioner keeps pressure on it, making it so the chain can't jump off the gears. The only risky part of this system, is you still have a chunk of metal hanging off your drop out, making it really easy to hit it on something.
The new System:Top View
While the older system is primarily designed to aid in allowing short travel full suspension bikes to run a single speed, this new tensioner is geared to the hardtail rider and their frames. Since chain rings are often not perfectly round, this set up is really beneficial to those trying to get the ideal wheelbase length and not have to worry about overly tight or loose chains.
This system allows you to install it between the bottom bracket and the frame. In doing this, it allows you to keep the rear drop outs clear, and clean, which lets you creep a bit closer to those roots, are hug that rock just a little closer. Another big benefit to chain tensioners is that they allow you to run a single speed dual suspension bike. Without this design we would all be relying on horizontal drop outs, or running a derailleur in the place of the tensioner. Expect to see these on slope style bikes and dirt jumping bikes world wide this season.
Stay tuned in to see what bike it ends up on!

the only TRUE way of solving all tensioning issues with ver DO's is to buy the White Industries ENO Eccentric Rear hub.
Its the only one of its kind and is a sure fire way to get your ss dialed.
I have tried all the main tensioners.
dmr, rennen, home made, surly....
they dont work good. they suck
I purchased the ENO hub and my problem has been solved.
look in to it. It isnt cheap but it solves ALL ss problems and issues.
I HATE tensioning Issues.
