I am not a fan of Bontrager wheels mainly because I have found, based on limited experience, that they are harder to get tires to mount to. But otherwise I have had no problems with either rim. That said, more spokes are better and your open pro wheels are probably going to be a tad more serviceable than the bontrager.
Also, you dont say what hub you have mated to the open pros. Bontrager hubs are often DT Swiss design and are usually pretty good. But if you have something like a Shimano 105 or better hub with the Open Pros, I would go with those.
They are 105's with the open pros.They also have eyelets while the Bontragers don't attesting to its quality.I think I am going to switch them.Also I see the open pros paired with a lot of high end bikes.I've been riding the bike and I really like it.It's my first Aluminum frame.Up till now its been all steel and one Ti,a litespeed.I'm surprised how much I like the ride.I like the ride more than the titanium but less than the steel.
