    ZTR Grail Disc wheelset 1675g (THE PAIR)  

    Ride without limits. Pavement, gravel, cyclocross, and even singletrack: the Grail MK3 is ready to outperform the competition on every surface. Stan's tubeless technology offers less rolling resistance, more control, and the ability to seal most punctures almost instantly while you keep riding. The Grail's versatile BST-R rim design makes it compatible with tubeless road tires, low-pressure tubeless converted tires, and conventional tires and tubes, offering maximum flexibility in a single wheelset. Upgrade your bike to the leading tubeless rim design, and find out what you've been missing.
    The Grail MK3's internal width and patented Bead Socket Technology rim design are optimized for 25-40mm tires. The truth is out that wider is faster, and the rim shape of the Grail MK3 lets you get the most speed from your tires, while also improving tire stability at speed and control in the corners. Nothing beats Stan's patented tubeless rim design for getting the most performance from your tires.
    All the advantages the Grail MK3 offers on the road are even more noticeable once the pavement ends. For cyclocross and gravel racing, the optimized tire shape and added stability offer a distinct advantage. The Grail MK3's rim shape is even designed to avoid tire pinch flats, allowing 'cross and gravel racers to run lower pressures that absorb impacts and improve traction.
    For peace of mind on longer rides, the Grail MK3 offers outstanding reliability. Nobody likes flats. Combined with Stan's sealant, tubeless tires have the ability to seal punctures while you keep riding, adding a new level of security and convenience. Constructed from lighter, stronger 6069 series aluminum, the Grail MK3 rim is also strong enough for serious adventure on and off the pavement. With triple freehub bearings, co-molded seals, and full CNC machined bodies, the Grail's Neo Durasync hubs are ready for high mileage in all conditions. Laced with traditional and readily available j-bend Sapim spokes, the Grail MK3 is built to be the only wheelset you need for anywhere the ride takes you.
    Fast, tough, and featuring the most trusted tubeless technology in the world, the Grail MK3 is ready to improve every ride, both on and off the pavement. Find out just what your bike can do with a Grail MK3 wheelset.

    BST-R TECHNOLOGY
    BST-R rims offer maximum versatility with the widest range of tires and pressures. Compatible with 25mm to 32mm tires at pressures up to 115psi both with and without tubes, BST-R rims are also compatible with wider, higher-volume tubeless tires at pressures below 45psi  
    BST-R Tubeless Technology for Higher Pressures
    Our BST-R rim shapes are designed for maximum versatility, and can be used with a wide range of tires. Higher volume tires 32mm to 50mm wide can be used at pressures up to 45psi (3.1 bar). The BST-R rim shape can also be used with 25mm to 32mm road tires specifically designated as "tubeless" at pressures up to 115psi (7.9 bar). BST-R rims can also be used with tubes, at pressures up to 115psi  
    Key Differences Between BST and BST-R
    Our BST system was developed specifically for tubeless use with pressures below 45psi. From our Iron Cross to our Hugo, we offer low pressure BST rims for tires in the 32mm to 122mm width range. The broader pressure range of our BST-R Series rims and wheelsets means they're optimized for tubeless use with tires in the 32mm to 50mm range at pressures of 45psi or lower, as well as 25mm to 32mm tires specifically designated as "tubeless" that feature reinforced beads designed for pressures up to 115psi. Both BST and BST-R rims and wheelsets may be used with tubes
    The patented design of our BST-R rims secures the tire's bead, creating an air tight seal that lets the tire expand to its full volume. The result is more traction and less rolling resistance for increased speed  

    WIDERIGHT TECHNOLOGY:
    We all know the most important piece to the bicycle-terrain interaction is the contact patch between the tire and terrain, so tire profile and tire pressure play huge roles in bicycle performance and overall handling. But many rims just don't work well with the tires we're all using. Rims that are too narrow fail to offer sufficient sidewall support and protection to your tires and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tire profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tire's volume. Our WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function
    Though its roots can be traced back to the original Flow and Crest rim designs, we officially began the WideRight design philosophy with the introduction of our carbon rim shapes. With our new MK3 (always pronounced Mark 3) series, WideRight expands to our aluminum rims.
    WideRight rim profiles allow the tire to achieve its proper shape, and that's the foundation for a great handling, fast-rolling, and responsive bike.
    Our WideRight system makes it easy to find the perfect rim width for the tire size and volume you ride. Too narrow of an internal rim mixed with a high sidewall design gives you a "light bulb" tire profile while an ultra wide rim on a narrower tire will give you a flat to "bell shaped" tire profile. Neither of these scenarios give optimal tire profiles nor allows the tire to perform as intended.
    WideRight profiles provide the optimal volume without distorting the tread pattern or the side knobs so each part of the tire is in the correct position for rolling and cornering, allowing for maximum traction and control as well as offering minimal rolling resistance. The WideRight profile advantages don't stop there. Proper tire profiles not only allow for optimal tire performance but also allow the tire to do its secondary job of protecting the rim as well as the tire's sidewall. A flat or bell-shaped tire profile leaves the tire exposed to sidewall cuts and creates undue chances for rim damage
