Bomb Axle Tensioners

Believe it or not, these little guys are super important for those who do not want to power out of the gate and have your rear wheel pull out of alignment making your chain lose. These tensioners prevent your rear wheel from moving and eliminate the chance of your chain popping off. Piece of mind has never been so good!

YESS ETR-Horizontal Chain Tensioner

Crupi Factory Elite Pro Mike Moeller won't ride without it!

Unlike other “chain tensioners” on the market, this device actually applies tension to the chain rather than just fixing the axle position.

The Yess ETR provides the best of both worlds, it does what the other tensioners do PLUS it applies a sprung tension load up on the chain. This achieves two important ride conditions: Chain tension; so that the chain doesn’t jump off the sprocket, Chain wrap; for better torque and pedal efficiency. This solves the problem of tight and loose spots due to imperfect sprockets and Chain Rings.

For those who are tired of dealing with Chains that are either too long or too short and can’t seem to get the right length even with the half-links, this will blow your mind away. The ETR feeds off of chain sag and allows the rider to maximize their pedaling by reducing chain friction.

Frustrated with always adjusting your racing style to match the wheel base? And with the change in axle position, the brakes need to be adjusted as well. This also includes swapping cassettes to match the track you want to conquer. With the Yess ETR Horizontal, you never have to adjust to your position again, the tensioner accommodates you.

The ETR features Oil lite bushings for never-ending lubrication, chain guide plates, fully adjustable chain line, floating pulley and a CNC Stainless steel pivot pin. The body and arm are individually CNC machined in house for the best quality and tolerances.
