    Is this rim OK to ride hard without worries?

    So, I went through this sharp rock garden like there was no tomorrow at 28psi (rear)...
    Do I need to worry about that crack? New rim just to be safe?
    Mavic xc 717 with tubes.

    Thanks in advance.

    The crack says replace it.

    The trouble with common sense is it is no longer common

    Mavic maxtal rims, more dent resistant than standard 6000 series rims but they also tend to crack when you do dent them.

    Rim is toast, time to replace.

    Thanks a lot for your replies guys. I've been riding mountain bikes for at least 20 years and always have had Mavic rims and I'm a tube type guy. Maybe it's time to try some other brands.
    Based on your experience and from what you may have heard, can you recommend me a rim from this sub 450gram list? (32yo, ex-downhiller, 175lbs and no mercy on my fuel ex):
    Sun Ringlé inferno 25
    Sun ringlé Helix 25
    DT XM 401
    Spank OOZY 26 AL Evo
    WTB KOM i23
    WTB Frequency Team i19

    Given your ex downhill background, I'd go just slightly heavier and get the WTB Frequency Team i23 at 455g in 26". Added bonus is they are super easy to set up tubeless if you ever want to go that way in the future (i19 and KOM i23 will be too).

    The Sun Ringle Inferno rims are solid, the Helix is similar but with a tubeless profile. The WTB Frequency rims are solid as well. If you're going to bomb through rock gardens then I'd go with a wider and stronger rim. Maybe the WTB Frequency i23 or the Sun Ringle Helix 27.

    The 717 is the lightest, weediest, thinnest walled rim Mavic sell, a 319, 719 or 521 from Mavic will be a lot more survivable. EN521s are especially popular for being very strong but cheap-ish and light-ish.

    I recently built up some Halo Vapours. The are just a hair narrower than the wtb i23s at 22.4mm internal width. I am enjoying them so far and would recommend taking a look to see what you think.

    Given your weight and the way you ride, you'll likely break all of those rims within a couple years. I'm 150 lbs but tend to be hard on wheels since I ride like an out of control maniac at times, I've found that 450 grams or so is the dividing line between wheels that live and wheels that die, well, unless carbon fiber rims are an option. Out of your list the KOM i23 and OOZY 26 will likely live the longest, but I'd highly recommend going to a heavier & stronger rim. I'd say WTB Frequency i23 as a minimum and preferably the Spank Subrosa 30 or Spike 28 Race. Mavic 719 is also a solid rim, I still use them on one of my bikes, but I've come to prefer wider rims and use the Frequency i23 on my newer sets of wheels.
