Review on Jagwire Cable Adjuster Mickey Adjuster by Jamal Murph

great product. The best rope tensioners. The only downside is that they are heavier than others, but the difference is negligible. 4 grams heavier than Jagwire's plastic regulators. They're not bad, but Mickey's are more reliable and more precisely tuned. They are used to attach frame cables, but I install them on all rear derailleurs, even if an adjuster is connected upstream. Facilitates tuning in no time and in the garage. Highly recommended. Oh, and by the way, they work great with Shimano and SRAM.
