Johan Bornman Posted June 10, 2009 Share That wheel design is doomed. It was flawed from the beginning. The notion that a slender-spoked wheel should go from tension into compression at each cycle is where it all started. They then expected a slender column to support the wheel in the load affected zone. These columns buckle easily. However, I suspect it is't the buckling per se that causes the break, but damage done in the tension cycle that then causes stress risers for Euler's buckling to do its thing. Mavic has lost the plot and needs to employ more engineers and less marketers. Mark my words, we're going to see a second and final recall on R-Sys wheels before more customers fall on their arses.

BB69 Posted June 11, 2009 Share I crashed in January in CT. There was not a single spoke left in the front wheel. I broke my collar bone and scapula. The other rider in the fall was left with a few scars and very littele damage to his bike. I have received the "second edition" mavic R-Sys front wheel but after reading the article posted yesterday don't really want to race on these wheels. MAVIC are refusing to replace my set with an alternative set of wheels untill this case has been investigated in full by MAVIC in France. Link to comment Share on other sites More sharing options...
AndreZA Posted June 11, 2009 Share That is why carbon spokes were banned in the 90s. Then a DT swiss spokse were like 50-80c and a carbon one R3-50. Link to comment Share on other sites More sharing options...

gummibear Posted June 11, 2009 Share THATS why I don't like/trust MAVIC I like Mavic and have ridden them for years but i dont buy very light wheels.I don't see how they can last if they are to light. Link to comment Share on other sites More sharing options...

timbrink Posted June 15, 2009 Share that is one seriously frightening story! also a well-balanced and well-written piece of journalism. Of course it gets a whole lot better balanced when Mavic is afforded the opportunity to respond: http://www.velonews.com/article/93240/mavic-responds-to-wheel-collapse-article Link to comment Share on other sites More sharing options...

Free Posted June 15, 2009 Share Rolling a clicher tyre off a rim?! Thats bull. The response from mavic is even a bigger load of bull. If the tyre came off in a corner you would slide and fall on youre side...not go over the handlebars and ending up on youre head. Even if their fairytale contains any truth, no wheel should disintigrate when a tyre comes off or in the event of a crash. I rolled a tubby before in a crit but I stayed upright because the rim still supported me and the bike. Link to comment Share on other sites More sharing options...
