While pictured is both 10.5 and 12.1 tonearms, this listing only includes the 10.5 tonearm.

"The »10.5« is considered one of the best tonearms in the world and is used as a reference (and highly recommended) by magazines and reviewers alike throughout the world. The »10.5« is a true allaround tonearm. With a dynamic mass of 12 grams, it works well with any modern cartridge; and with 10.5'' length, it is still short enough for most turntables designed for 9-inch arms, yet also long enough for 12-inch arm bases."
