Rotor will launch their own electronic group later this year

Among the novelties that the Eurobike fair left us, the new adventure of the Spanish firm Rotor in transmissions caught our attention. After the hydraulic UNO drive group, which had limited implementation, Rotor is now betting on an electronic transmission hand in hand with the Chinese manufacturer Wheeltop, with whom they have created the new UNO.

Rotor is already working with Wheeltop to revive the UNO group

Those of you who have made a purchase of cycling material on the well-known Aliexpress platform may recognize the Wheeltop brand, as you have surely seen some advertising from them. It is a Chinese brand specialized in bicycle transmissions and has its own wireless electronic group.

An experience in the manufacture of transmissions that the Spanish Rotor has decided to take advantage of, together with them, to develop a new electronic group that will revive the UNO denomination used by the innovative hydraulic group that the brand had in its catalog but had minimal market implementation.

Like with the previous one, the new Rotor UNO will be a group suitable for road, gravel, and MTB, and, as expected, it will be compatible with the brand's cranks, chainrings, and power meters from Ajalvir.

The collaboration between Rotor and Wheeltop goes beyond just putting their name on a group from the Chinese firm, as they have collaborated with the oriental manufacturer to contribute their experience in electronics. In fact, Rotor has been developing its own power meters for some time now, as well as their expertise in CNC machining to achieve a lighter and faster group than what Wheeltop currently offers.

Little more has been revealed about the development of this new group that the brand intends to launch in September coinciding with the celebration of the Sea Otter Europe fair. However, it is undoubtedly a bold adventure given the existing oligopoly in the transmission market dominated firmly by SRAM and Shimano, which account for almost all the factory assemblies of bicycles sold, except for a small residual percentage that are equipped with brands like Campagnolo in the high-end range and Microshift in the entry-level models.
