bought this with the Birzman Sprocket remover, been removing cassettes for years, the tools have usually rattled around when they engage on the lock ring. The pin provides makes for less rattle, less chance of undoing the lock ring eccentrically due to the 12mm pin. Provides more support, more…

I wished I had this a few years ago having struggled in the past to keep the tool stable so not to slip, this has made changing the cassette much simpler.

This did not fit my DT Swiss 12mm thru axle on my 2017 YT Jeffsy 27 so had to be returned which was annoying
