I thought I would post this up as I had trouble finding this info when I was researching fatbikes.
I bought my first fat bike 2 Weeks ago and I have to say it is a blast. I decided I wanted all carbon to keep it somewhat lighter, the 27.5 wheel size was intriguing me and I didn't really want a super wide Q factor and rear end as I would like to run it as a 29+ bike in the summer when trail-a-biking the kids. Pedaling comfort and sportyish feel were somewhat of a priority. I bought the Suzi Q as soon as I saw it. It is a awesome and fun.
The Maxis Minion FBFs came on it and I have to say they are a great rolling tire. I was curious if I could squeeze a little bigger tire in the Suzi Q. A little more width would be good for float in the snow we have here in CT now but I also wanted to take advantage of the 27.5 wheel size and get a larger wheel diameter.
I could not find any info on the Barbegazi fitting on the Suzi Q and published specs by RM indicated it might not. I figured I would give it a shot and I was happy to find out it fits easily. There is at least 10mm in all directions including chain clearance in the big cog.
Below are some fit pictures. I will get some better pictures as soon as the blizzard snow and 50mph winds die down here.
Some other size references that might interest folks. These are all on a Mulefut 65sl 27.5" wheel and at 15 PSI set up tubeless.
