Stan's No Tubes Flow S2 Wheel

This specific model is built for a 12mm x 142mm thru-axle standard. Please double-check your frame's rear spacing before purchasing, as this is a non-boost spacing standard that may not fit modern boost-spaced frames.

The Flow S2 is designed for trail and all-mountain riding. Its reinforced 6061 alloy construction and 30mm internal width are engineered to handle technical terrain, rough descents, and aggressive cornering where durability is a priority.

The E-sync hub features 8.18-degree engagement, which provides a quick, responsive feel when you need to ratchet your pedals over obstacles or start accelerating immediately out of a slow corner.

Yes, Stan's wheels utilize their patented Bead Socket Technology, and the rim comes pre-taped and ready for tubeless setup. You will just need to add your preferred sealant and a tubeless-ready tire.

This wheel is compatible with standard Shimano/SRAM 8, 9, 10, and 11-speed cassettes. It is not compatible with SRAM XD or Shimano Micro Spline drivers out of the box.

A 30mm internal width provides a wider base for your tire, which improves sidewall support. This allows you to run slightly lower tire pressures for better traction and control without the tire feeling squirmy in corners.
