  Product Description
Freshly released from the Yess Laboratories, the ETR-V is Yess’s newest addition to its family. This tensioner is designed especially for converting bikes with vertical dropouts into a single speed. Meant for people who like to simplify their bikes by eliminating all excess gears and derailleurs, the ETR-V does what other single speed chain tensioners *attempt* to do.

ETR-V Suspension Conversion provides everything you need to install the ETR-V onto a Full Suspension Frame. The first of its kind, this kit allows Full suspension frames to convert into single speed. Unlike Yess's other tensioners, this pulley pulls the chain downwards away from the chainstay. This is to counter the "chain pull" as the frame goes through its travel. The roller included in the kit keeps the chain wrap constant and maintains it at 60%.

The Vertical tensioner is meant to be installed on the derailleur hanger. The problem with the current ones in the market is it is either spring activated at the mounting point or it is adjusted and fastened to the position, both have their own flaws.

The spring activated ones on the market have the issue of being flimsy, since it is only mounted on the hanger threads, it can be knocked off easily. Another problem is that there are no adjustments for spring tension (other than getting a different spring) some riders try to solve this issue by using a rubber band or a ziptie!

The ones that are fastened to the position of tension are built solid, however, it does not “float”. There are always issues of tight and loose spots while pedaling because of imperfections on the sprocket or chain ring. It is never 100% round so there will always be that slight variance. Not only that, but it may be hard to get the correct chain length. Even with half-links, you probably won’t be able to get the right length. This being said, the chance for the chain to come off the gears is still there and it will still pedal with inconsistent feedback.

With Yess, using their old tensioner design for BMX (designed over 10 years ago) combined the best of both worlds. It can be adjusted in multiple positions, first is fastening it solid to the hanger at two spots (Axle and Derailleur mount). Second is utilizing spring holes at different locations to adjust the tension of the pulley arm. Third is the pulley adjustment for the chain line, once in line with the chain its fastened with a set screw.
