Open Pro/DA Wheel Ticking(11 posts)

Open Pro/DA Wheel TickingCurtSD

Hi,
I've got a pair of wheels with Open Pro rims and DuraAce hubs with about 2800 miles on them. Just recently the rear wheel started to make a ticking noise. I've swapped in a different wheel and the problem went away. I checked the hub, and it felt smooth. I tensioned up and trued up the spokes, and that had no effect. Has anyone else experienced this, and do you know a solution - it's very irritating!

Thanks,
Curt

Scrap the rim and don't replace it with another OP. The failure rate of these rims is unbelievable. Yet people still insist on them for high end wheels. I'll admit, they are great wheels right up to the point that they start clicking.

So this is a common issue with OPs? Is it covered under warranty - the wheels are only 4 months old. Barring that, what's the best alternative for a rim for a fairly heavy rider (200 lbs)?

Thanks,
Curt
Should be covered under warranty as rim joint failure.Quack

The rim should be covered under warranty. As far as an alternative rims goes, 200lbs is not that heavy and any rim should do. If you go away from the welded rims, I think the susceptibility to clicking is reduced, but you can usually feel the rim joint while braking. I've built wheels for 200lb+ buddies using OPs, Sun ME14As, CXP-33s and haven't had any problems with durability.

It is a common problem with OP rims.
I went through the issue when putting together my bike about a year ago. My brother knew about the OP clicking problem and steered me away from them.
I went with Ambrosio Excellence and have been very happy with them. They are also a little bit more exotic (and stronger according to some) than OPs.

Before you scrap the rim, try oiling the spoke nipples and eyelets. That cures my OP ticking.

The problem is either one of two things. One, the Open Pro rim is held together at the joint by a small pin while it is welded and machined. This pin sometimes works its way loose and creates a rattle. Two, the eyelets are commonly known to creak and rattle like crazy. This seems to be quite common after the rim has its first rainy, wet ride.

Personally, I have a rear Open Pro with two or three cracked eyelets (eyelets, not the rim material itself) and it is ridiculously noisy regardless of spoke tension or lube. The wheel is about 3 years old, but has been used in races only and probably has less than 3000 km on it (not my only race wheels). I was quite surprised to find the cracked eyelets. To be honest, these rims are not nearly as good as their reputation leads to believe. I am replacing both front and rear with Ambrosio Excellence clinchers. They are a bit heavier, but not by much, and they are reportedly very durable.
I went with Campy MontrealsDY

I was all set to go with Open Pros, but I was so put off by all the stories of clicking that I went with the Campy's. Even if only a small percentage of the OP's develop clicking, I didn't want to deal with it. The Montreals are a nice stiff strong design and only 10 or 15 grams heavier than the OP's and a few bucks cheaper too. The only downside is that they don't come in colors if that is an issue. Only Silver.
Same prob fixed with a dab of...B2

of super glue. I also had a cracked eyelet that was incredibly obnoxious. A little dab of superglue between the eyelet and the rim solved the problem.

I've also had creaking noises that were solved with a drop of oil between each spoke/eyelet.

I've also had creaking noises that I just haven't been able to solve. Finally bought new wheels.

I have exactly the same prob w/ open pro SUP and Ultegra rear hub. Started after about 2500 miles. Hub is fine. I can recreate the tick by flexing the wheel at a certain point. I think the prob lies in a rim grommet - I think I can pinpoint the tick when I flex the wheel. The problem grommet looks like it might be splitting. I think the Open Pro is advertised as having "double" grommets, and I wonder if one has separated. Any insight will be appreciated. I'm at the point of giving up on this wheel.

Oil the grommets! One of the posters suggested oil on the grommets. yesterday AM I put a drop of motor oil on the 4 or 5 grommets in the rim area I suspected of being the source of the annoying tick. Avoid getting oil on braking surface. Duh. Has worked so far - 100 miles; no tick. Might be worth a try.
