I have two sets of Open Pro rims - 36 rear & 32 front. Although they
are sold as rondonee, fast club rides and good second tier race rims,
I have found them to be quite durable. I also have an Open Sport that
I use for commuting and generally abuse. It has been a pretty good
rim, but has developed a very small flat spot after about 4,000 miles
of hard use. The Sport, is wider, but I have mounted 35's on the Pros
without any problem. I weigh 180 lbs but seem to have better luck
with wheels than many others on this list. I run the Pros on my
Sunday ride and the Sport on my commuter.
If you will want a little extra zipp than the Pro is a good choice; if
your mostly looking to carry a load and have the extra durability,
than I would buy the Sport. Rims are funny. The best wheel builder
in VT swears by Mavic rims & I have good l have had good performance;
but I know another very good builder who prefers the Velocity rims.
I'm sure there both good.
