The Arch S1 wheelset also features Stan’s faster-engaging, CNC-machined Neo hubs.

The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tyre profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tyre's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tyre volume and sidewall function. BST (Bead Socket Technology): Bead Socket Technology rims are designed to match the shape of your tyre's bead to create a safer and more secure airtight interface. BST rims secure the bead of the tyre, not the sidewall, creating an airtight seal while allowing the tyre's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, Stan's BST rims are also lighter and stronger by design and accelerate more quickly. Neo Hub: The Stan's Neo hub has a 100% precision CNC machined hub shell that is both incredibly light and strong. It features a 4 pawl, 36-point drive system for amazingly quick engagement. Oversized bearings ensure maximum durability and the swaged axle & wide bearing stance is 3 times stronger than conventional designs. There is a high durometer main seal integrated into the hub shell and the Sealock end caps lock into place bringing unmatched smoothness.Buy Stan's No Tubes Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
