    • Be aware, this blue is dark
Review Image by Rob Rob
I originally purchased blue, but it does not match my big ripper. So I went with the silver color, which looks good. I didn’t realize the blue that came on my bike was not the same. They seem to be putting on all the parts now.

    • Did the job
Great micro-adjustment to get tension and tire angle just right. A lifesaver for single-speeders

    • Poorly designed
I give 3 stars for price and outward appearance, on the flip side , the side that actually comes in contact with your dropouts, thumbs down on the stair step design, would be perfect, if machined without the step cut, then the tension bar would butt flat against dropouts

    • They do their job.
The tensioners were a bit too long for my bike so I cut the first hole off and they fit perfectly. My wheel hasn’t moved since installation and I don’t always hit the sweet spot of landings. 🤘

    • Well-made, but too wide
Well-made. Problem with the 2 hole design is it can make the device too long to fit, It was too long for my fixes frame so I ended up having to cut off the section with the second hole.

    • Works on a fabricbike light with minor modification
Tensioner worked fine, but the way they're designed meant that they wouldn't sit flush with the dropouts- that extra little step in the metal on the tensioning plate made it just slightly too wide. Easy fix with a hacksaw and file
