When we introduced our Pasta Party in 2021, we hoped it would be popular. Nowadays it has become almost the most popular model we sell… honestly, we shouldn’t have been so surprised, this bike shreds!

The Pasta Party is the bridge between our Purple Haze and the Crumble, or maybe the glue that holds them together… who knows! While both the Purple Haze and Crumble are down for a party as well as buckling down and getting down to business, the Pasta Party is truly the suit-and-tie XC bike of our line up. That is, tie-dye suit and tie with cutoff shorts, naturally.

We built the Pasta Party to be a thorough-bred with a wild hair. Pare the bike down with lighter components and fast tires and this thing will rock local XC Fight Club races. Or dress it up with some more adventure gear and chunky tires and send it all the way to Kyrgyzstan.

What makes this bike so special? A modern XC-based geometry paired with our very own passion for trail riding and adventures. A made-especially-for-Sour tubing set and custom bits all over the frame makes the Pasta Party truly a unique frame.

All of this, built by hand in Saxony!

All Sour frame are now made in Germany, by us, right here in Saxony. Production pre-orders happen quarterly, but frames can be ordered at any moment of the year. With the exception of special orders, sizes, and frames, all orders are expected to have a 6-10 week delivery time.



Handmade Sour Bicycles CrMo frame featuring heat treated, multi-butted tubing.

Our dropouts and 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.
