Eurobike 2018: Rotor hints at the future with launch of first 1x13 road groupset
New groupset designed for road and gravel use
Rotor has launched a new player on the groupset scene with a new 13-speed hydraulic setup at Eurobike.
Don’t worry Campagnolo fans, it hasn’t just outdone the Italian brand with a 2x setup, but it is taking on the 1x hegemony currently held by SRAM.
The hydraulic technology used to actuate shifts is borrowed from the brand’s Uno groupset, while the shifters themselves are the Uno models when installed on a road bike. The flexibility of the system means that there’s a lot of cross-compatibility – you could run the groupset on a mountain bike – but, naturally, with specific shifters for that purpose.
In terms of gearing, Rotor has showcased the 13-speed cassette in a 10-36t format aimed towards roadies, and a 10-39t wide-range format that opens up the gravel sector. You could also run 11-46t or 10-52t models too for greater flexibility, if you wished.
The cassettes make use of a Shimano/SRAM HG-style freehub, albeit with some additional spacing inside to help accommodate the 13 sprockets. That said, the spacing between teeth is the same as the current 1x12 groupsets around, so you won’t need a specific chain to run it.
You’ll be able to match your chosen cassette to 38, 40, 42, 44, 46, 48, 50, 52 and 54t Q-ring chainrings, which should cater for anyone from a weekend gravel rider to a full time road pro.
Indexing is handled entirely by the rear derailleur, which can also be tweaked using an on-board switch to operate using 12-speed cassettes too.
Prices and weights are still to be confirmed, but we’re intrigued to see how it rides on gravel and road bikes when it makes its way to us.
