      1) Square taper crank puller

      2) Preload adjustment tool for Shimano outboard bearing cranks

      The first tool is a crank extractor (Kurbelabzieher in German), as far as I know. It is used to remove the chain ring, crankset and pedals from the crank bearing, where the pedals turn around. Sorry if my English is not perfect.

      First is a crank remover and second is a preload adjuster for Hollowtech II cranks
