Apeks Black Sapphire Enviro cap tool

[Pao]

Is there a special tool to remove the environmental cap? I'd hate to mar that nice black PVD finish. Is a strap wrench good enough? The wrench flats are angled so using an ordinary wrench might be a tad difficult.

A 37 mm socket + a piece of bike inner tube over the enviro cap works great!
