To create the Flow EX, Stan's NoTubes took its multiple World Championship and World Cup winning ZTR Flow wheelset back to the drawing board and tweaked a few things to make it even more durable than its predecessor. With a wider rim profile, lowered, thickened sidewalls, and the improved spoke bracing angles of Boost hubs, the Flow EX 27. 5in Boost Wheelset is ready to roll fast over the most technical trails and resist damage from hard hits along the way. Billed as a bombproof all mountain wheelset, the Flow EX features a wide 25. 5mm internal rim width and 29. 1mm outer width to provide a solid platform for your tire of choice. The Flow EX incorporates Stan's Bead Socket Technology BST, which features notably low profile sidewalls that allow the tire bead to seat more effectively. BST results in an exceptional tubeless seal while also allowing the tire to hold a greater volume of air than standard rims, so the tire maintains its full shape for a wider, more stable rolling platform. Pairing BST with the ability to run up to 30% lower air pressure than on a standard clincher wheel results in more stability, better handling, solid cornering, and better overall control. These rims are also compatible with standard tubes, and the lower sidewall drastically reduces pinch flat risk by reducing the amount of material present for the tube to pinch against. This means less time sitting in the dust wrestling with a flat at the side of the trail and more time shredding your favorite loops. Stan's laces the Flow EX rims to its all new Neo OS hub set featuring smooth spinning, oversized bearings that glide on a stiff, strong, swaged axle. The Boosted Neo OS holds the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs and utilizes four precision pawls that simultaneously engage a forged steel, 36t ratchet ring for snappy, ten degree engagement. Stan's builds in its new SealLock end caps for easy installation and Sli...
