I have yet to put maximum tension on the Surley, but so far the Singulator has worked flawlessly in turning my beater MTB into a single-speed. And, while more expensive than some other models, I have heard those cheaper models can be very noisy. This is pretty quiet and simple to install, with an impressive build. I did not replace my freewheel as recommended but have not thrown my chain yet.
As I said, it could have been a few bucks cheaper, maybe, but that is not on Modern Age. Surley seems like a cool company, though. (Go steel frames!)
Easy to install and align. I would recommend to others who want a simple and robust single speed tensioner. A fine product that I like better than other pulleys I have installed.
The only downside is you need a sorta special narrow thickness wrench for the final tension of the pulley.
