Simucube is the Finnish maker best known for its reference direct-drive wheelbases, and the Tahko GT-21 is its first in-house steering wheel. It's a 320mm D-shaped, CNC billet-aluminium GT rim with quiet magnetic shifters, native Simucube wireless and a dedicated button for on-the-fly FFB tuning without leaving the sim. The pitch is build quality and a cohesive, zero-config Simucube experience; the catch is a conservative input count for the price and total ecosystem lock-in, since the wireless only works on Simucube bases.
