Founded in 1946 in the saxon town of Oederan, at a time when in Saxony the soviets enforced the industrial dismantlement in these occupied zones, Grünert focused all the time of production on aluminium parts for mostly bicycles and later motorbikes. Grünert is mostly known for rims and stems used on the german Diamant racing bicycles. Their development has been down to the political and economical circumstances of the GDR (German Democratic Republic), founded in 1949. This cumulated in the fact that Grünert has been expropriated in 1972 and became a part of the state combine MZ Kombinat Zschopau, a motorcycle maker. After the political changes in Germany and the end of the division in two states the Grünert family could restart again their business in producing bicycle parts. But the necessary investment was too big so they went bancrupt in 2001. The brand Grünert is still in use for bicycle rims by Büchel, a company which is associated with the Vuelta group.
