Thanks to MOTO rim technology, this wheelset offers gravel riders greater control and durability on challenging terrain, whilst ensuring a smooth ride that reduces rider fatigue. This translates to a significantly more comfortable ride. Imagine riding over unpaved roads as if on a magic carpet, especially with high-volume tubeless tyres at low pressure. This wheelset is ideal for gravel racing, adventure riding or any long day in the saddle.

Zipp 101 XPLR MOTO Tubeless Disc Rim:

The single-wall rim featuring Moto technology is optimised for off-road use thanks to its Ankle Compliance construction. The single-wall rim design offers outstanding comfort.

The hookless tubeless rims are only suitable for use with tubeless tyres

Thanks to Zipp’s patented ABLC rim profile (Aerodynamic Boundary Layer Control), drag is reduced even when the wind hits the rim at an acute angle rather than head-on. The effective angle range here is significantly greater than with comparable rims. This is achieved through a special effect, similar to that seen on a golf ball. This is why Zipp wheelsets feature numerous small dimples on the rim surface. In addition, Zipp utilises VCLC technology (Visco-Elastic Constrained Layer Control), which involves incorporating highly shock-absorbing, visco-elastic materials into the carbon matrix. ZIPP’s Carbon Bridge technology uses Kevlar fibres woven into the edge area of the carbon matrix to increase impact resistance. The deep sidewalls further dampen vibrations. External spoke nipples also ensure easier maintenance without any aerodynamic disadvantage.

The 101 XPLR wheels were developed using the Total System Efficiency approach. The development goal was to find the best possible wheel design to overcome the speed barriers encountered under realistic riding conditions. These include not only wind resistance, gravity and rolling resistance, but also vibration losses on poor road surfaces.

Zipp ZR1 Disc Centerlock Hubs:

This hub set features an improved seal design and faster response thanks to 66 engagement points on the freehub body. The hub set’s durability was proven through more than 58,500 km of test rides, which formed part of 3,222 test hours. It incorporates key technologies from the Zipp Cognition hubs. The seal design is based on Cognition, with a larger dust cap behind the freehub body and improved seals for greater protection. The bearing size is also the same as on the Cognition, although the Cognition uses premium bearings. The six pawls are staggered to operate in two groups of three. Three pawls are always engaged at any given time. This design creates a quick engagement feel with 66 engagement points. The freehub body is designed so that the pawls remain in place during disassembly to simplify maintenance. Zipp hubs are designed for use with J-bend spokes, the most popular type of spoke today. J-bend spokes are widely available and easier to replace.

Hookless TSS (Tubeless Straight Side) rims:

are characterised by a hookless rim profile. Unlike hooked rims, they lack a mechanical interlock between the tyre bead and the rim flange. On hookless rims, the tyre is held in place solely by the tyre bead and the frictional forces between the tyre and the rim sidewall. On a hooked rim, the tyre is additionally secured by the mechanical interlock between the tyre bead and the rim flange. Hookless setups are more sensitive to potential deviations in system tolerances. It is therefore essential that all specifications regarding hookless compatibility provided by tyre and wheel manufacturers are followed. Adherence to the maximum tyre pressure and maximum inner rim width is crucial for the safe use of hookless rims. The maximum specifications for air pressure and inner rim width when fitting to hookless rims and rim flanges can be found on the tyre packaging.
