Concept2 Model D

By the Watta Team · Updated

Concept2 Model D: The Concept2 Model D is the previous-generation name for the Concept2 RowErg, the world's most popular indoor rowing machine, now sold under the RowErg brand.

What is Concept2 Model D?

The Concept2 Model D was the flagship indoor rower from Concept2 for decades before being rebranded as the RowErg in 2021. The Model D established itself as the global standard for rowing ergometers, used in every major rowing nation and at every level from recreational to Olympic. It features an air-resistance flywheel, nickel-plated chain drive, and the PM5 performance monitor. The Model D is identical in function to the current RowErg — the name change was purely a branding decision. Millions of Model D units remain in active use at rowing clubs, gyms, and homes worldwide. The machine is known for its durability, with many units lasting 15+ years with minimal maintenance.
