The Arch S2 wheels by Stans are built to withstand the demands of today's trail bikes and eBikes. The E-sync hubs are designed for durability, with features such as a pawl design that reduces stress on the freehub and bearings, heavy-duty cromoly steel axles, and double-row Enduro bearings. The hubs also provide fast engagement, needing only 8.18° of rotation to engage simultaneously and drive you forward.These wheels have a versatile 28mm internal width, ideal for 2.2-2.5" tires. They are made from 6062 aluminum, with a sleeved joint and stainless steel rim eyelets. The patented BST low-profile rim shape makes tubeless inflation easy and ensures a reliable seal.

This program includes a 3-year warranty for the E-sync hubs and S2 rims, a 1-year crash replacement, and a $10 donation to a trail maintenance or advocacy group of your choice.The Arch S2 wheels by Stans are a reliable and high-quality choice for your bike, offering durability, versatility, and a range of benefits through their connection program.Please note: This product does not include 'Upgrade Bikes'.
