Open Pro UST is rated 3.2 out of 5 by 10.
Rated 1 out of 5 by from mounting tyres on new open pro UST To introduce myself. I am 64 years old and an experienced randonneur, riding approximately 8 to 10000 km per year and usually build my own wheels the conventional way, aluminium rims, 32 wholes, spokes crossed by three. Today I spent 4 hours to try to mount tyres on my new wheels mounted with new Open Pros UST rims. I completely agree with the other comment on this same place. It is a nightmare! I tried it with a Continental 4000, 28 mm, a Continental 4 Seasons, 25 mm and a Continental 4000, 23 mm. I managed to mount after 1 hour the back wheel with a Continental Grand Prix GT, 28 mm. However, I did not manage to mount the tyre on the front wheel, trying it with all the tyres mentioned above. Interestingly I have more than a dozen wheels using the old Open Pro rim. With the same tyres mentioned above, I am able to mount anything without even a tool. I also have wheels with DT 440 and 411 rims, on these rims , it is also more difficult to mount tyres. However, I never experienced such difficulties as with your ne Open Pro rims. Something is really wrong with your new product!

Rated 5 out of 5 by from Works as advertised. I just built up a pair of wheels with these rims. They were easy to build with and turned out great. I mounted up some Yksion Pro UST tires. They were easy to mount and sealed with a track pump. Couldn't be easier. Unfortunately the weather is horrid so I won't be able to ride on them for a while. But so far I'm pleased.
