Winter bike / Snow bike thread

It's been interesting watching your deisgn progress. I've been following the fat bike threads on MBR as I'm loving all the innovation and have seen your questions as things have progressed. I see that a lot of people are running 29er wheels for summer use due to the larger effective diameter giving them a similar geomatry to that of the BFL's.

I know you already have a 29er but am interested as to why your not tempted to take the same route. I'm guessing you're looking at Nates for summer which seem very aggressive and serious mud pluggers (interesting thread on trail damage with them the other day) or have you found a more summer centric tyre option in 3.7"?

My 29er is a weight weenie, single speed. The fatbike will have more cush, load carrying abilitys, and gears. Definitely an overlap there. But different enough for me to want to own both. Lightening the wheels of the fatty seems futile, when my Longboard is sub 9Kg. In the same way, as adding load carrying options to the Longboard would be futile considering the local terrain, and its lack of gears.

One more very good reason not to build a set of 29er wheels for the fat bike. Is the cost and availability of Hubs. Financially it makes little sense to sell the 29er, and buy extra wheels. Great option if you dont already own a 29er/ summer MTB, though.

My summer tyre of chioce would be the Husker Du from 45NRTH. Obviously I'm just guessing from the appearance. But it seems to have the same sort of pattern as my preffered WTB Weirwolfs. Which work well on alpine trails. I'll probably just end up running the BFLs all year though. I'm more concerned with the bike being future proof, than immediately versitle.
