Box_tensioner_one_blk
Box One™ Chain Tensioners are extruded then CNC-machined from 7075 aluminum for an optimal balance of strength and weight. A minimalist design adds style while reducing their overall mass. Laser-etched graphics that include wheel position guides and two 10mm mounting holes ensure perfect adjustability on most frames every time you remove and replace your wheel.
When used properly, Box One tensioners will protect your frame dropouts and hold your rear wheel in place. Keep in mind, however, they aren’t indestructible (neither are your dropouts). Install these lightweight chain tensioners with care and leave the 15-inch breaker bar in your toolbox.
Material 7075-T6 Aluminum
Weight 62 grams / 2.2 ounces

What Our Customers Say
★★★★★
A great shop with a thoroughly professional yet human approach. I have been ordering from them for a long time and there has never been any problem. Communication works perfectly and you know where you stand right from the start.

I now have my second Haro bike from Katmar Bike Center – this time an e-bike. Completely satisfied. Professional and helpful approach. I warmly recommend this shop.

Reliable. I bought a new chain, it turned out to be unsuitable, but exchanging it for another one was no problem.
