My front Mavic Open Pro rim ....

[HLaB]

Yikes my sirrus has Mavic Aksium's and they are about 6500 miles old and the front shows no sign of wear, the rear does so its become a turbo bike. The Dutch Quasar rims on the Kinesis are at 9500 miles old now but I've been keeping an eye on them and the lbs a few months back thought they had plenty of life left in them.

Worried now, had mine on for over three years and living in the chilterns the brakes take a beating, especially as i ride my best bike all year round. Well that's possibly one item on my shopping list for the NEC cycle show!

I have Open Pros on Ultegra hubs on my main bike and they are very nice wheels but assessing wear without an indicator is a problem (although perhaps not much of one in Suffolk).

My no. 2 bike has Ambrosio Evolution rims on Ambrosio Zenith hubs which I bought new but cheap on Ebay. The rims are one step down from an Open Pro (the equivalent model seems to be the Excellence) but they are so good that I keep umming and aahing about putting them on my main bike. The hubs have cartridge bearings and are amazingly smooth running, the overall ride quality seems identical and they have wear indicators. All that stops me changing them over is the ticking freewheel, which I find a bit annoying.

The Evolution is a little heavier than the Open Pro and the rim is pinned, not welded but it still looks quality. I once gave the front wheel a turn, left my workshop to go back indoors, came back again several minutes later and it was still turning.

Yeah but you are all forgeting about why we all prefer Open Pro !!!

OK they wear out quick and they have always have done. NO THEY AINT MADE IN POLAND !! they are a French wheel.

Here is my reason why I think you should stick with Open Pro

1 The gloss finish on the black rim is seconed to none

2 The finish on the none black (I have no idea what it is :-D) is second to none

3 The best lightweight wheel you will get for the money

4 The best wheel build you will get (pending your local bike shop)

5 As the finish on the Open Pro is so good when you clean em after 12 month abuse they come up like new

6 They have them double butted things inside the rim. no idea what thet are though they look good n strong Maybe double butted ??
7 They are made in France !!!!!!!!!!!!!

Sorry for the rating bad grammeer :-)

I think most people would probably think that the Excellight is the OP equivalent, but many reknowned wheelbuilders rate the Ambrosio hubs (actually badged-up Novatecs) for their high bang to buck ratio.

I'm sitting here rebuilding a front wheel. Just weighed my MA3 rim (that's an Open Sport in new money), and it's only 470g. So hardly a boat-anchor, and maybe one to consider also.

I had the same wheels on my Audax bike and thought they've been pretty good - the rear rim lasted about 6,500 miles. I've had to replace one set of bearings in each hub, but the cartridges only cost about £5. Am about to have them rebuilt as my winter wheels.
