Sour Bad Granny Bundle limited edition
This limited edition Bad Granny is delivered as raw as the day it was born. Together with Brainfart Industries and Cyber Cranks we’ve curated the most ready-to-klunk Bad Granny build we’ve ever dreamt up. Raw steel cranks, raw steel bars with integrated dropper. Perfect.
The Bad Granny has been around since day one here at Sour. We wanted a fun side-project, and an homage bike seemed like a perfect fit. Singlespeed it, run gears, race it, ride it, commute it, it’s up to you! This frame can handle it all, as long as “all” ends with a cool beverage and good company.
The Bad Granny looks the same as the OG mountain bikes, but it is anything but ancient. Boost spacing, internal dropper routing, and all the other modern day standards are present and accounted for on this frame… no worries about running fancy robo-shifting if that’s your thing!
All of this, built by hand in Saxony!

Bad Granny Raw Limited Edition Information:
We take pride in our expertise in powder coating colors and their application. Although we have always declined requests for completely raw frames (even our “raw” frames come with a special clear powder coat), for this limited run, we have decided to let nature take its course.
The frame, fork, cranks, and even handlebars are completely raw steel, they will rust. None of these parts will ever been sold as raw again.
Rust is your friend. With raw steel, a little love now and again will help develop a beautiful patina while also avoiding problems in the long term.
To protect the inside of the frame, we always apply a wax coating, we do this to all Sour frames. However, the outside of the frame and parts will be left raw. To preserve these parts, we will provide a bottle of Sour Frame Oil, a perfect blend of love and linseed oil.
