Hi, I know there are a lot of threads already about wheels but a quick search didn't give me many answers.

I have a 2006 enduro expert which came with some normal generic hubs on sun SOS rims. Last year in the alps I bent the sun rim so had to buy a new wheel out there. I bought a atomlab trail pimp which seems like an absolute beast of a rim so far. Recently however my rear hub has started to give up the ghost. I am wanting to replace my wheelset (f+r) and keep the atomlab as a spare. I am fairly light ~ 11st but ride pretty agressively in mainly rocky terrain - peaks and lakes mainly. I won't be doing any drops over 6ft but don't want to have to slow down just because there are tons of rocks infront of me. Fattest tyre I run is a 2.5 maxxis in summer, normally 2.3's. Tubeless is something I would like if possible.

My options

1) Crossmax SX - the most expensive option but seem pretty good and have UST

2) DT swiss EX1750 - look brilliant and light weight but I checked them out in bike shop and rim profile looked very skinny and the shop said they dint easier

3) Mavic EN521 on pro2's - supposidly "enduro" class rims balance between strength and weight? No ust

4) Mavic EX823 on pro2's- heavier than others but will be tough, have wide rim profile and are ust compatible

5) Sun singletracks or whatever the eqivalent is sun make now - equaliser 29???

There you have it, lots of info, any suggestions welcome, only chose pro2 because of good reviews, any good alternatives?

Most hub/rim combinations are possiable below the cost of the sx's 

I am an owner of a set of the original Crossmax Wheels. When I brought them there was no choice of XS, SL SLR etc, it was one choice. Which was aimed at a cross country use.

Like 4Ass, I ride in the peaks and these wheels proved to be bomb proof. Nothing ever buckled them and even to this day they are still true. I have never had them retentioned and I used them regulary for 3 years.

But I dont use them any more because they are broken, because the hub was shite. I didnt know this at the time, but the seals in the freewheel were letting water and grit in and after a while the spindle that the freehub sits on wore down about a mm. This is enough to make the cassette rock slightly and can cause the gears to change. 

So the wheels are now sat in the shed.

But because I know how strong and light these wheels are, I inted to buy some of the SX's for my new freeride build. I know that if the cross country version can take a load of hammer, then surely this new breed of XS type should be even stronger. And as I now know the hubs might be a problem, I can check on a regular basis and clean them if necessary and hopefully get longer than 3 years out of them.

I had the same problem with the 823s Wayne. Had to rebuild one twice, keep an eye on the eyelets if they're not threadlocked in they work loose and screw up the spoke tension. Since I stripped it and threadlocked it it's been fine.

ProIIs on DT5.1s are strong and light but not tubeless, unless you do a conversion.
