“What does it all mean?” This was the first question I asked DT Swiss at the launch event for the new GRC 1100 50 and 30 wheelsets—and I wasn’t having an existential crisis. I wanted to know how on earth to make sense of DT’s naming system. It turns out there’s a method to the madness.
What I learned is that the letters at the beginning denote the product category and rim material. Three letters means high end carbon, two letters means high end aluminum, one letter means entry level aluminum. Then there are the numbers that follow, which express hub type. 1100 or 1200 means DT’s 180 (highest end) hub, 1400 or 1501 means 240 hubs, and so on down the line, with the four different hub options DT manufactures.
Why DT choses these numbers to represent the hub types is a separate conversation, but at least it makes it clear how one would go about deciphering these names. Finally, there’s the descriptor at the end, which refers to the spoke type (Dicut means T-type spokes, FYI).
Apologies if I’ve lost you here—for those so inclined, there’s a video explaining it all deep within the recesses of DT’s vast and information-filled website.
