BAD GRANNY LIMITED FRAME SET

Sold Out! Thanks everyone who bought a pre-order Bad Granny! We sold out of these in one weekend… wild!

All Sour Bicycles frames are made by hand, one-by-one, in our own facility in Saxony, just outside of Dresden. We use custom tubing designed and drawn for our frames, it’s a multi-butted heat-treated CrMo steel that’s ready to stand the test of time. All our steel is produced from a partially recycled product and drawn by one of the worlds leading production facilities in Taiwan, the beating heart of the worlds bicycle production.

Our dropouts are designed in-house in Dresden and have a replaceable derailleur hanger.

The seat clamp is designed in-house and is integrated into the frame. Should it ever fail, the frame can be professionally modified to use a traditional clamp, if repair of the original clamp is not possible. We have never seen one fail.

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.
