Ive just been speaking to the current owner of these wheels and they were originally built by wadescycles, who apparently did a pretty shoddy job of it, so his brother (who is a bikeshop mechanic) rebuilt them as good as you can get. (apparently hes very good at it).

So after hearing that and reading what the majority of you have said (fine if theyre built well) i think theyll be fine.

All agreed? 

yes i agree they are very good , hope you enjoy then 

i use singletracks on my slopestyle bike which gets some serious abuse, and have not had any problems with the rims (I built the wheels)

I used to use Singletracks in 26" (front) and 24" (rear) on my Big Hit and send 25 foot vertical drops, huge step-down gaps and all the dirt jumps at Woburn sands regularly without any issues....


if the wheels are built well, and checked / maintained regularly then you should not have any issues with Singletrack or similar lighter rims like Mavic EX 721s  (the old 521)

a heavier, stiffer rim can actually build into a weaker wheel because it won't allow the wheel to flex under loading and can pop spokes, rip out eyelets or end up bending

what you generally get with a heavier rim is more resistance to denting as the rim sidewalls are thicker, but denting is not really an issue for DJ riders, more for DH riders who hit rocks and roots at high speed whilst running lower tire pressures for grip


its all about the quality of the wheel build, and how much you keep an eye on your wheels

the DMR D-V (made by Alex) is not a bad rim, but its VERY heavy for what it is, and not particularly tough in terms of denting resistance

I have been using my singletracks for DH for 5 years and they are in perfect condition still.

single track 24inch are super strong i used them on my old crosser street bike and they held up reallly nice mate

cheers
