mavic letters and numbers

stubs

anyone know what the letters and numbers mean on mavic rims ie xm719 or ex 721

nicklouse

the letters are the "usage" and the number describe the rim.

why? what do you want to know?

letters are the usage (XM = cross country, EX = Heavy usage). First number is quality, higher the better. The last 2 numbers are the rim width in mm... 21 = 21mm, 19 = 19mm

xm is all mountain, xc is well, xc!

The first number is quality, but 7 is the same as 8 except for 8 is also UST

No... they changed last year. The old XM became EN and XM is now a cross country rim.

In the world of rims, the XC racing rims stays the same, with the XC717 and XC717 Disc, the mid range freeridey/allmountain XM321 Disc is now called the EN321 Disc and is in the Enduro FR category. It's getting a popular lightweight but tough rim and you can stick big fat 2.5" tyres on there. Cross mountain rims stay largely the same, but there is a new rim called the XM719 Disc. It's meant as a mid/high end all round XC disk specific rim, weighing in at 460g with single eyelets using Maxtal alloy and SUP

All in all pretty confusing!

so as you can see it can be a minefield out there so back to my question what do YOU want to know. Then you can be given that info rather than lots of this and that.

XM = cross mountain
XC = cross country
EN = enduro
EX = extreme
D = downhill
F= freeride

Some are older than others! The first number represents class of rim , the latter its width. But it has not always been like this.

Take the above as a generalisation.

EG XC 717 is a premium rim, the '7' being a pinned and welded rim, with a 17mm internal diameter. 8 is a UST rim. 6 is a ceramic rim. 3 is a budget pinned rim. 1 is the OE stuff.

You forgot:

TN = twenty nine
