Stan's ZTR Alpine Disc Rim has a shape that is based on their previous lightweight champion, the ZTR Olympic, yet the Alpine is lighter. The ZTR Alpine Rim is designed for those who need the lightest possible rim for racing. And like the name implies, climbing with a superlight rim such as this makes you long for extended sufferfests high in the mountains. Compared to the ZTR Crest, it's 1mm narrower at 20mm inside and 10 grams lighter. As Stan's No Tubes continues to improve their BST, or bead socket technology, their rim weights continue to plummet. On the Alpine, the bead hook is nearly imperceptible and the sidewalls are just tall enough to allow a seal with the bead of the tire. As they trim the fat from the outer portion of the rim -- the sidewall and bead hook, they can add material as needed to the wall thickness to ensure that the ZTR Alpine is strong enough for racing, yet light enough to satisfy the nitpicking weight weenies.The shorter BST sidewalls are stronger, more ding resistant, and lighter. The inside of the rim is perfectly matched to the bead seat diameter of a 26" tire. This makes the tubeless seal a good one, though the tires will be a very tight fit on the rim. In our experience, a set of thin but flat levers works best for installing/removing the tires. To make them tubeless you'll use Stan's yellow tubeless tape and one of their tubeless valve stems or one cut from an old inner tube. Stan's BST tubeless system creates tubeless seals that burp less, leaving you with more air inside your tire and not on your mind.Stan's ZTR Alpine Disc Rim is anodized Black or powdercoated White with red decals and is available with 28 and 32 hole spoke drillings. The 17.5mm deep, V-shaped rim is pinned, welded, and machined at the joint for a true sidewall. They will work with or without tubes. If you're building your own wheels, you'll need to know that they have a 536mm ERD. The claimed weight is 330g.

Looking at purchasing a ZTR Alpine or Crest wheelset for the upcoming XC season, and am now looking at a good tyre combo to complete the package.
For the last 2 years I have run a Racing Ralph/Rocket Ron combo on my Anthem with tubes, but have been told by a couple of local XC riders that the new ... Read More »
I would like to build a wheetset for XC ride, maybe occasionally trail ride. I also intend to use if for XC race.
Any thoughts between Stan's Alpine and Crest?
Is Crest stiffer than Alpine with insignificant 20g penalty?
Thanks!Read More »
I might need to replace my front rim and have been looking at options, it looks as though Stan's rims have the best weight to strength ratio and I like idea of BST. My only problem is that my current front hub is 28h and that means I would have to use a ZTR Alpine on the front. Is this ... Read More »
I am 135lbs and XC racing in the pacific northwest. These will be my daily training wheels as well as my race wheels. I already have some DT Swiss Hug 240 hubs that I will lace one of these sets of rims up to.
I'm planning on using DT Swiss Revolution spokes (2.0/1.5) with aluminum nipples. Does ... Read More »
I need help choosing between these two rims for a rear wheel build on a bike I am building. The bike is an 08 BMC Trailfox 01 that I hope to equip with a X-Fusion Velvet and 650b front setup at 130mm. I don't think I can run a tweener wheel out back, so I am now looking for the best setup for trai ... Read More »
