turns out they work pretty darn good too.

I waited several months to get these in the color I wanted for a Salsa Fargo upgrade for which I wanted the ease of maintaining mechanics brakes. They were well worth the wait! Definitely pricey for a mechanical brake, but by far the strongest I’ve used and near the stopping power of the Shimano hydraulics on my other bike (I can lock up easily with one finger on Apex levers).
Box came with all parts needed including compressionless housing and easy-to-follow installation instructions. Prior to buying these, I dabbled with hybrid brakes on the Fargo and I regret that time and money wasted. Should’ve gone with Growtecs from the start.

Had a set of Klampers which are great but were just too big for my Salsa Fargo. Put a set of Growtacs on and they're easily as strong as the Klampers, easier to adjust and, most importantly, compact. The brushed purple also matched the titanium finish better. Klampers wound up on my Bridge Club and they're doing a great job and work better on that geometry. For the price and size, you can't go wrong with the Growtacs in general.

They were easy to set up, look really good and I particularly appreciated all of the cable and housing that came with it. These are a little on the spendy side but they work really well and have way better lever feel and power than any other cable actuated disc brake I’ve tried.

Fantastic brakes. They do what you say. A lot more stopping power compared to my original mechanical brakes.
