Rear 519, three months ago - http://www.btinternet.com/~peteajones/temp/splitrim.jpg

I am now running a 618...with a 317 on the front which seems to be holding up OK.

Thanks for the info, I was tempted by the 519 because of its wider profile, shall have to
reconsider..

I run about 40# in the front and 45-50 in the back. WTB Mutano Raptors..

My understanding is that the "silver anodizing" is exceptionally thin, and not as likely to
develop cracks large enough to propogate to the rim, while the anodizing for the "dark colors"
must be much thicker. I suspect you're right about all the Mavic rims being anodized (though I'm
not sure about the MA3).

If you look on the site, it shows different symbols, some of which appear on each rim's label. Each
of these symbols relates to a different property of the rim, or a process it has undergone. One of
these is for 'Hard Anodising', and does AFAICR, only appear next to the coloured ones.The silver
don't have this, and I know I'm light at about 155 lb, but I carry heavy packs, have a heavy bike,
and am clumsy enough to give my wheels hell - never had a problem. Worn 2 of these (521's, silver)
rims out (sidewall wise) without any signs of fatigue failure.

How much tension do you use in your spokes?

Same here, you must have a better batch of rims than JD and I have had.

Is the 519 really all that much wider? If it's the same weight while being wider I would think that
would mean thinner walls and more chance of splitting.

That would make sense to me if they were the same weight but are they really? . The F519s are 24.5mm
wide and listed at 460g. The x618s are, what, 22mm wide? and listed at 450g. What do double eyelets
add to the weight of the rim?

After having troubles with Bontrager Maverick and Corvair rims splitting along the inner bed and
F519 rims cracking around the spoke holes, I started switching to Bontrager Clyde rims for my rear
wheels. They're 24mm wide but are of a triple cavity design and are listed at 505g. Not quite a
Rhyno Lite but they've certainly been worthy of their name so far.

It's not that much wider at all. The 519 might be a decent choict for a front wheel, but is just as
shitty as the 517 as a rear wheel. The heavier weight of the 618 is made by the double eyelets,
which is why some may think of the 618 as "heavy" in a weight weenie XC sense.

The bottom line is this, the 517 and 519 are **** if you ride a lot. Even Hemo The Magnificent
toasted his Gerd-built 517s and he's 170lbs soaking wet. If you want to be stylish and listen to
Mavic's hype, ride them. If you want a dependable wheel, get the 618.

I'd guess it's my riding style.

I'm more of a road rider that just wants to stay away from traffic than a real mountain biker. If
there's an easy way and a technical way, I'll take the easy way every time. If there's only a
technical way I'll take it - but I'll make a mental note to avoid that route next time....
