Stan's No Tubes Arch S2

Yes, the Arch S2 is specifically engineered to handle the increased torque and weight demands of e-mountain bikes, making it a reliable choice for electric setups alongside traditional trail and enduro bikes.

The 28mm internal rim width is optimized for tires ranging from 2.2 to 2.5 inches, providing a stable platform that balances sidewall support with a predictable tire profile.

Stan's patented BST low-profile rim shape is designed specifically to make tubeless setup easier. It allows the tire bead to seat quickly and creates a secure, reliable seal with minimal effort.

Yes, the Arch S2 uses traditional J-bend lacing. This is a standard design that makes sourcing replacement spokes simple and ensures any local bike shop can service your wheel without needing proprietary parts.

The E-sync hub features upgraded double-row bearings and a chromoly axle, which significantly increases its torque capacity. This makes the hub more durable and better equipped to handle the stresses of aggressive riding and high-torque e-bike motors.

Yes, the Arch S2 is available in both 100x15mm and 110x15mm (Boost) axle configurations to ensure compatibility with a wide range of modern suspension forks.
