    Looking for a good racing rim

    Aluminum - thinking of DT swiss xr361 or xm 421 - just wondering if the 421 is too wide at 25mm inner width?

    Neither of those two. Way too heavy. Either American Classic MTB Race or Stans Crest.

    NoTubes Crest - best rims for the money, light weight & NoTubes rims hold beads better than most others for tubeless.

    I raced Arch Ex rims for the last season: at 150 lbs they were not durable enough... It all depends on your support and the tracks you are riding. Here in Germany: courses are not demanding technical wise but that doesn't mean anything: tracks are fast with a lot of roots... A lot of high speed hammering. My Yeti ASRc broke down after three races as well, main pivot bearings destroyed the frame...

    Like most things it depends on lots of factors, I don't know anything about the American Classics but the Crest is pretty skinny and I think any tire wider than 2.1/2.2 would be sub-optimal on them.

    My vote for an alloy rim goes to WTB KOM, I'll take the extra weight. Carbon ftw.

    I've been running Crest MK3's for a year now. They are very light. 'Too light' I thought when I unpacked them... but I ride them in training and racing and they have yet to have any issues. I love them.

    They are a little flexy, so up your spoke count and you'll be fine.

    I use B.O.R. 366 rims on my XC bike and been really impressed, the hold bead and seal really well, nice and light and make a good stiff wheel. They do a lighter one too (the 333) but the rider weight limit was a bit keen for me so went with the heavier rim.

    They have a good race pedigree in endurance and marathon events too.

    Thanks - for the input - I'd rather go with a heavier weight rim and piece of mind. -

    23mm internal width isn't wide enough for XC racing?

    Another vote for the crest mk3. Really no negatives about them. Mine came in at 360g and 370g. Much stiffer then my old pair and the extra width was a noticeable plus.

    Hard to bet the new Crest MK3, even if you go carbon.

    Much stiffer than before, wider and lighter.
