Stans NoTubes Arch MK4 rim

The Stans Arch Trail, Freeride and Enduro rims with an asymmetrical profile, 28 mm rim width, really sturdy yet weighing just 457 grams

Developed with the help of the Stans Enduro World Series team, the new Arch MK4 is ready to tackle any trail. Despite the increased rim width to 28 mm and featuring the proven lower BST rim bed, the new Arch MK4 retains its low weight for excellent acceleration and climbing performance on ascents. With the WideRight System introduced by Stans NoTubes, the rim width increases to 28 millimetres – for even better tyre support and full volume development. Inspired by Stans carbon rims, the new rim profile, combined with the new 6069 aluminium alloy, increases lateral stiffness and impact resistance whilst reducing the risk of snake bites.

The Stans NoTubes rims are perfectly designed, thanks to special rim flanges for fitting tubeless tyres. Thanks to the wide rim bed, the tyre is guided superbly and offers excellent rolling resistance. With the Stans NoTubes tubeless conversion kit, the ZTR Arch rim can be upgraded to a very lightweight tubeless rim. Thanks to the asymmetrical rim profile, very laterally stiff and durable wheelsets can be built using these rims.

Notubes BST

Notubes’ Bead Socket Technology. This special rim design features a wide rim bed with a low flange for high tyre stability and full tyre volume development. The BST technology helps retain air better in tubeless systems, resulting in less rotating mass and a virtually increased effective rim width compared to competitors. A wide rim also reduces tyre flex in corners and allows the tyre to be ridden at lower pressures. The ZTR rims are fully tubeless-compatible when used with rim tape and a valve.
