Mavic A319 Rims

Lack of sockets at the spoke holes (joining upper and lower walls) means
they're not as good as MA2s... or A719. A719 can take higher spoke
tension; generally an excellent touring/utility rim, IMHO. A319 should be
stronger than MA3 though.

I rode my new bike yesterday which has Mavic Ksyrium Elites with flat
spokes. I was caught by surprise at how much of a strong sidewind the spokes
catch and was nearly blown off!

I believe the expression is 'carrying too much sail for the conditions'.

The Mavic website claims the A319 is socketed:

As far as I can tell, the only advantage to the A719 over the A319 is
30g weight saving and more drilling options. Oh, and a welded rim joint,
but whether that's an advantage is debatable.

Hmm I think I'd be better of with 'heavier' (and thicker) rims anyway,
as my MA3s are obviously made from camambert, being concave and overdue
due for replacement after only 14 months use. I have V brakes which is
obviously part of the problem and I've done reasonable mileage but I
still can't afford to have to replace wheels every year!

I'll check what I have. They are Mavic something or others and have
been well chewed by V-brakes on normal commuting. The rear is
definitely going concave and the front not far behind.
I am strongly tempted to move to disks. Just costing the difference
between getting new front forks, headset and stem, front wheel, and a
hydraulic front brake, (up to around 200 quid) vs just buying a new
bike such as the giant Terrago disk at a mere 400 notes.

Problems with my computer mean I can't get the pdf to load up now but I
don't believe that's correct. I thoroughly looked into the specs (via
various sites) at the time I chose rims for my tourer. I would have got a
pair of A319s if they were socketed. I have noticed mistakes with
pictures & diagrams on mavic.com before. I opted for A719 rear (for high
strength & reliability) and MA3 front (to economise).

I think the weight saving comes from the socketed design, which is able to
use less material and a lighter alloy, yet have greater strength overall.

In this case the extra weigh doesn't make it stronger. It's an inferior
cheaper design. I doubt thickness at the braking surface is much/any
different. The extra material is reinforcement inside the rim
(alternative to sockets).

Well, if you're right, I agree -- socketed definitely wins over single
eyelets.

PDF now loaded. Blimey, that page does look convincing so I could be
wrong... or out of date....

Interesting note at the bottom: "The Mavic rims not mentioned in the above
[2006] chart have not changed. The technical features can therefore be
found in previous years' technical manuals". Does this necessarily mean
the rims in this chart have changed?

For what it's worth, I made a wheel with the A319 rim a few months ago
(See the "Hub dynamo wheelbuild - spoke length" thread from October).
The rim does have double eyelets. I can't compare to MA2s, but I've been
very happy with the A319 on my daily commute on rough (currently
regularly gritted) roads. Time will tell on the longevity. I could
measure the amount of aluminium between the breaking surface and the
wear-indicator pit, if you're interested.
