Description

The Stans Flow Rim MK4:

Since 2007, the Flow rim has been helping riders progress, push boundaries, and do more on their bikes. The original Flow was light, wide, tubeless, and strong as hell. It redefined mountain bike rims and played a role in the evolution of riding. Today’s Flow MK4 continues the progression with a 30mm wide asymmetric rim designed to build an even stronger overall wheel.

Durability and an almost uncanny feeling of control on the trail have made Flow rims the preferred choice of multiple Red Bull Rampage riders, and today’s Flow goes even further. The Flow MK4’s reinforced spoke bed, combined with the offset drilling of the asym design, builds into an incredibly durable wheel that brings added confidence to every ride. Unlike many asymmetric rims, the Flow MK4’s BST-Asymmetric shape is designed to equalize resistance to dents and tire bead retention on both sides of the rim under even the worst rock gardens and hardest cornering. Combined with Stan’s patented Bead Socket Technology, the Flow MK4 rim offers the easiest tubeless setup and most reliable airtight performance on the trail.

Ramp up your progression and make every ride even better with the confidence of Flow MK4 asymmetric rims.

Strada Says:

The Stans Flow MK4 rims are the most durable of all Stan’s rims. They are ideal for a such a wide range of trail riding. They have an internal width of 30mm which is optimised for up to 2.6” tires and an offset of 3mm. Available in 27.5”, and 29”, the 27.5” Flow MK4 rim weighs 487g, while the 29” version come in at 521g. We think they work best with the high quality brass A.B.S anti vibration locking nipple, which although more expensive does prevent loss of spoke tension. Hubs: We can build these with Hope Pro5, DT Swiss 350 and DT Swiss 240s and Chris King ISO. We usually build these 32 hole 3 cross lacing with double butted stainless black spokes. If you are a bigger rider then we may opt for our E-Plus spokes.
