TektroHD-M500 Gemini Hydraulic Disc Brake Set Dual Piston Caliper with 160mm Rotor, MH2012

I don't see a lot of reviews here so I thought I'd add mine.I put them on my surly Karate Monkey. The install was super easy all I needed was zip ties, a few allen wrenches, and wire snips (to cut zip ties). If you have internal cable routing you will have to disassemble the brakes which is above my mechanical skills. The hardest part is getting the calipers set up so they don't rub on the discs. YouTube can coach you through this process (that's what I did). Front brake hose is a bit long.I haven't hit the trails yet because of pesky Michigan winter hanging on, but they are great in my driveway test drive. I will update my review as I use them more and answer any questions to the best of my ability.good luck.
