The title of this post about sums it up. Here are the latest crank offerings from e13, also known as The Hive. These are compatible with the 100mm bb shells currently used on all production fat bikes, the Salsa Mukluk and Surly Pugsley included. Bottom line is that these are about the lightest, sexiest, and stiffest cranks you can throw at fat bike.
Here's the money shot. The 100mm compatible spindle.
These things are as visually stunning as their standard offerings. They are also one of the lightest set ups you can run on a fat bike. The set in our shop weighs 887 gms with bb and spacers. That's close to the weight of a normal XT crank from Shimano. These are also priced pretty competitively at $350. If you want go fast fattie cranks, these are as good as it gets. Stop in and check them out for yourself.
