German-made bicycle company Sour Bikes has a new all-road bicycle model. It’s been in the works for a long time. After four years in the “planning hopper”, taking their time to “do it right, and do it our way”, the new Sour Space Cake is finally here.
Sour felt that there was a significant gap in their bike offerings. A road-plus bike was the thing to fill the gap. They set out to design something fast and efficient, but something that could “get weird when the road turns rough”.
Space Cake to Tackle the “Paved” Roads
After countless prototypes and test rides, the Space Cake is here and Sour says it’s the most “road” bike they’ve ever made. The geo is tuned for long road days and adds durability. The tubing and frame parts are designed to be as light and efficient as possible.
Gone are the road bikes of yesterday. No more ultra-skinny, high-pressure tires on a “one-trick-pony”, road bike. This all-road bike is built for when the paved road fades into a gravel road and you want to take the long way home.
Sour says the Space Cake is light, responsive, and built for speed. Like all of the Sour bike models, the Space Cake comes with its signature, custom powder coating. Choose from bold, classy, or a little off-beat.
Mountain biking is at the core of Sour Bikes’ DNA, but they say all-road and gravel are at the heart of Sour’s off-MTB-season. As such, a bike like the Space Cake can be the perfect off-season tool even if you prefer knobby tires and full suspension.
