Looking forward to the build. What are you going to use for the rear hub?
Well the used Paul hub that I was going to buy from NYC the seller flaked on me. I went with a custom Onyx hub.

How is the front hub working out? Look forward to more on these builds! Happy trails
Parts are still coming in and I don't know if I'll have Baja in the cards this season. I will post up some trip report once it is done.

Well I just got a Manitou Mastodon 80mm Comp for my wife's Specialized Helga. She always wanted a fork but I just couldn't get her a Bluto. For a front wheel I have a take off from a Scott Big Ed that is a Syncros 80mm rim and 150mm Thru Axle hub.

After canceling the Baja Divide trip I still have the bikes being built up for a similar trip in the future. Not having a need for a bike light on my summer wheels I had the SON dynamo laced into the DT Swiss BR710 rim and wired to the Sinewave Beacon. I had the Onyx hubs built into the 27.5 Velocity Duallys for summer riding mounted with the 2.8x27.5 Schwalbe Nobby Nic Addix tires.
