Excerpt from BikeRumor
Offering up two new fat bike rims, Alex is introducing the Blizzerk 80 and Blizzerk Pro. While the 80 uses a pinned joint construction with hollow rails along the circumference of the rim, the Pro model steps up to a welded joint. The Pro is also a bit wider with a 76mm internal/ 82mm external width compared to the 80’s 80/73mm. If the Blizzerk Pro looks like a Surly Rolling Darryl that’s because it basically is with “technology by Surly.” Weights for the rims are listed at 830g for the 80 and 850g for the Pro.Link to Bike Rumor Article
On the + side, Alex has the new MD50 which is offered in 29″ and oddly, 24″. The rim features their TRS Tubeless Ready System with a Pinned joint and a 55mm ext/50mm int. width that is 22mm tall. Expect the MD50 to come in at 770g.Bike Rumor
