STANS ZTR FLOW EX RIMS REVIEW

Stans No Tubes ZTR FLOW EX

At first glance, the Flow EX rims look too light to be a strong and durable Downhill rim. Weighing in at 490grams (that’s 165grams lighter than a Mavic 823!) I expected them to only last a few runs before I would be changing them out. I was wrong.
Stan’s have put a lot of time and thought into the engineering of these rims, focusing on how the tyre works and designing the rim around its performance. The low profile of the side wall gives you a strong and durable platform which not only creates a fantastic bead edge for the tyre to lock secularly into place, but also allows the tyre to form its intended shape to give you optimum grip. This also means it has the ability to run lower pressures and reduces the likelihood of burping or pinch flats.
With the Stan’s No Tubes tubeless system, these rims are a breeze to build, not to mention that they bead and seal better than any other tubeless rim out there that I have ever had the pleasure of working with.
I have had the Stan’s No Tubes Flow EX rims built up on my bike for the last three national rounds: Thredbo, Mt Stromlo and Bright. Thredbo and Stromlo are without doubt two of the hardest-on-equipment tracks on the national calendar. These rims held up well; my wheels stayed true with no dents. The tyres maintained a perfect tubeless seal despite three small cracks appearing in the rear wheel by the end of the national championships round, keeping in mind that riders were destroying even Dee Max rims at Stromlo.
All in all I am extremely happy with these rims as a lightweight, cost effective race rim. They get my tick of approval.
