Thats the winter format, with 4.5" tyres. In the summer I will look to run 3.7" tyres, and push the rear wheel in some. With the 1.5" headtube, I could also fit an angleset headset, and have winter and summer headset angles. But thats a faff.
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"?
