Shimano: Essa is here
With the CUES groupset, Shimano has already successfully tidied up the in-house component jungle and regrouped all groupsets below SLX level. Now the entry-level components at the Acera, Altus and Tourney level have also been hit: they are experiencing a rebirth in the form of Essa components.
Essa has eight gears, so the cassettes have eight sprockets with 11 to 45 teeth with a decent range of 400 percent. The Essa parts are only available in a single-chainring version; you won't find a double or triple crank. This concept therefore only requires one gearshift. The chainrings are available with 32, 34 or 40 teeth, which are manufactured in a narrow-width pattern to prevent the chain from falling off. To keep the chain in check, the Essa rear derailleur has an integrated damper that reliably pretensions the cage.
