When I discovered fat bikes in 2019, I decided to build one. It took time to find the right things, and in April 2020, I started.

I ordered a Pole Taiga L (Pole Taiga page) frameset. It is slack and long, and I can run really big tires, specifically the Surly Bud and Lou.

It takes a surprising amount of parts to build a bike from scratch. Here is my list:

Frame & Fork
Frame Pole Taiga L
Fork Manitou Mastodon Pro Ext 120mm
Drivetrain
Bottom Bracket Praxis Works M30 Thru BSA
Crankset Race Face Crank Set Turbine CINCH System FAT 190 170 mm

Shifter Shimano XT SL-M8000

Derailleur Shimano Deore RD-M5100 11-speed Shadow Plus
Chain Shimano XT CN-HG701-11
Wheels
Rims Surly Clown Shoe 100mm set up tube less using fattystripper (Surly discontinued the Clown Shoes, so it was a tad hard to find two)

Tires Surly Bud 26x4.8 (front) / Surly Lou 26x4.8 (rear)
Mudguard Beaver Guard Mudguard - Mastodon
Components
Front Brakes SRAM Guide RE 4-piston

Saddle Ergon SM Enduro Comp Men M/L

The wheels are built by Stefan Buser of Lifestyle Cycles in Arlesheim. I simply don't trust myself to do wheels.

Just when I was about to order a 12-speed XT drivetrain, Shimano released the 11-speed Deore group set with a 51 teeth steel cassette. I decided to use that, mainly because that way, both bikes are 11-speed.

As of May 14, only the fork has arrived. I will share photos as I build the bike and of course once it is ready.
