I recently moved to Munich where there is (thick) snow on the ground for 5 months of the year and snow in the Alps, which are only 40miles away, for most of the year.
I therefore find myself "needing" both
1) A fat bike
2) A fat bike with a granny ring
This is even necessary not just for playing in the woods, where many of the trails become covered in inches of permanent ice under the snow all winter, but even for my ride to work, where the best route became unrideable most days, even in March and April. The On-One Fatty looks like a great option, but it "only" comes in 1x10 with a Truvativ SS crankset.
1) Can I fit a granny ring to these cranks? Despite there being a custom build option, I can not change them in the "bike builder" and I would need a granny to get up many of the mountains here in summer, let alone in the deep winter snow
2) If I can't, what are my options for a replacement 100mm BB shell crank, that will take a granny ring (for snow and hills) and a middle ring (for the fast bits, so I am not late for work)?
Thanks in advance I'm sure there has to be more than a few fat bike officionados on STW
