Shimano delivers technology taken straight from their flagship lines and pumps it in to this super affordable and versatile wheelset. The WH-RS-61 is tubeless compatible so you can run a tubeless tire with sealant that eliminates virtually all chance of getting a puncture while enhancing ride quality. For those of you not ready to make the jump to tubeless these wheel work just fine with a standard tire and inner tube.
Shimano uses a 21mm profile rim on the front and a 24mm on the rear to fine tune strength and ride quality. Like all Shimano hubs, they use angular contact ball bearings for easy serviceability although the seals are so good they will likely seldom need service. Shimano uses a forged hub shell and steel axle for strength. Double butted stainless steel spokes are laced radially in the front and 2x rear.
Anyone upgrading to Shimano/SRAM 11-speed might want to take a serious look at these wheel in terms of a budget-friendly, 11-speed compatible wheelset with the option to go tubeless.
The WH-RS61 wheelset is compatible with Shimano and SRAM 11 speed cassettes. They are supplied with a thin spacer to make them compatible with 8, 9 and 10 speed cassettes. Also includes front and rear skewers, 2-UST valves.
