The Stan's Flow S2 27.5 32H Rim is engineered for mountain bikers who want a strong, reliable, and tubeless-ready rim for trail, enduro, and aggressive off-road riding. Developed from the proven Stan's Flow platform, the Flow S2 combines modern rim geometry, durable 6061 aluminum construction, and Stan's patented tubeless technology to deliver excellent tire support, dependable sealing, and confident handling on demanding terrain.
Featuring a 30mm internal rim width, the Flow S2 is optimized for 2.3 to 2.6-inch MTB tires. This wide profile helps support the tire sidewalls and maintain an ideal tread shape, improving traction, cornering stability, and control. Stan's WideRight technology increases effective tire volume without excessively altering the tire profile, helping riders achieve predictable handling across rocky trails, loose surfaces, technical descents, and challenging climbs.
At the core of its tubeless performance is Stan's patented Bead Socket Technology (BST). The low-profile rim design creates a secure interface between the tire bead and rim, helping simplify tubeless installation and improve air retention. When properly set up with compatible tubeless tires, rim tape, sealant, and a Presta valve, the Flow S2 allows riders to take advantage of lower tire pressures for enhanced grip, comfort, and reduced risk of pinch flats.
The rim is manufactured from 6061 aluminum alloy and incorporates a reinforced spoke bed, stainless steel eyelets, and a quality sleeved joint for increased durability. Its 32-hole configuration supports a strong and stable wheel build, making it suitable for riders who prioritize dependable performance and long-term reliability.
With a 34mm external width and 18.2mm rim depth, the Flow S2 provides a solid foundation for modern mountain bike tires while maintaining practical wheel-building dimensions. The 27.5-inch version has an approximate ERD of 564mm, uses 33mm rim tape, and supports a maximum spoke tension of 130kgf (1275N).
Designed exclusively for disc brake systems, the Stan's Flow S2 is ideal for modern mountain bikes used for trail riding, all-mountain adventures, and enduro-style terrain. Recommended maximum pressure is approximately 39 PSI with a 2.30-inch tire and 34 PSI with a 2.60-inch tire, subject to tire manufacturer recommendations and riding conditions.
Finished in a premium Black/Gray color scheme, the Stan's Flow S2 27.5 32H MTB Rim combines rugged construction, modern tire compatibility, and reliable tubeless performance. It is an excellent choice for riders building a new 27.5-inch wheel or upgrading an existing mountain bike wheelset for improved strength, traction, and trail confidence.
