About 18 months ago I bought a Catalyst with Sun Rhino rims. This morning, on the way to work the back rim popped!
I knew it was worn but had hoped to get a few more months out of it before trying the carbide rims. As it is Xmas and want my bike asap I panicked and bought a Mavic 171 at the LBS. I am going to try to rebild it over Xmas (any advice appreciated).
I should have specced ceramic rims at the outset - but opted for the rhinos after using them on my triplet as a cheaper way of getting strong rims. I think I got that one wrong!
Anyway, 18 months isn't long - so if you have Rhinos - make sure you don't use the abrasive shimano brake blocks and check for wear. They may be strong but they are not very hard.
Happy Christmas.
