i ran a dx-32 up front for almost all of last season with absolutely no complaints at all. the weight is nothing you wont notice after a ride or two. i am now on a tioga dh rim but the dx-32 is great. go for it.
the tioga dh is one of the nicest rims you can buy. its double eyeletted and has a welded seam. its a nicer material than the alex rims too. its just better overall- hence twice the price. some people wouldnt notice.. they should save money and go for dx-32. im a huge fan of the tioga dh rim. some people dont like them because they lack the opposable thumbs it takes to get a tire off of it- god knows why...
I also thought about the tioga rim.. but I think it's not worth the extra money, as it's only 3mm wider than a tryall 32mm from rim, which is less than half the price. And it's lighter. Would be interesting to know the weight of a drilled tioga rim.
I'm also thinking about a completely drilled DX32 rim. Undrilled it's about 800?
