Pasta Party 32

Same concept, different scale

The Pasta Party has always been our fast, efficient hardtail โ€“ light on its feet, direct in its handling and balanced enough to ride long without becoming demanding. With the move to 32โ€ณ wheels, the goal was not to change that character, but to preserve it at a larger scale.

Rather than simply enlarging clearances, the geometry was reconsidered specifically for the bigger wheel diameter. Reach, stack and weight distribution were adjusted to keep rider position and frontโ€‘toโ€‘rear balance close to the original Pasta Party, while allowing the wheels to do their work without overpowering the handling.

The result is a bike that feels immediately familiar, but noticeably calmer and more composed once the terrain gets rough or the distance stretches.

Geometry designed around 32โ€ณ wheels

Larger wheels influence more than rollover. They change steering feel, trail behavior and how the bike reacts to rider input over time.

On the Pasta Party 32โ€ณ, head angle, front center and bottom bracket drop are tuned to strike a precise balance between stability and responsiveness. Steering remains intuitive rather than lazy, and the bike holds its line naturally without requiring constant correction. Weight distribution stays centered to maintain traction under power and confidence at speed. Instead of compensating for wheel size with extreme angles or exaggerated dimensions, we let proportion do the work.

XCโ€‘focused tubing for endurance efficiency

The tubing selection for the Pasta Party 32โ€ณ follows an XCโ€‘first philosophy, refined for longโ€‘distance use.

Tube diameters and wall thicknesses are chosen to keep the frame light and efficient without becoming nervous or harsh. Power transfer remains direct, while the structure stays calm under sustained load and uneven surfaces. This balance becomes increasingly important over long rides, where efficiency is not measured in sprint efforts but in how little energy is lost over hours.

The frame is designed to support large tire volume without excess material, allowing comfort and traction to come from tire choice rather than added mass.

Built for momentum, not acceleration

The strengths of 32โ€ณ wheels are most apparent over time: reduced impact on obstacles, improved momentum retention and smoother progress across broken surfaces.

The Pasta Party 32โ€ณ is designed to amplify these traits. Roots and rocks feel smaller, transitions smoother and maintaining pace requires less physical and mental effort. Especially on long XC loops, endurance races and ultraโ€‘distance rides, this translates into a bike that allows you to keep moving when fatigue would otherwise start to define your ride. This is efficiency measured in continuity rather than explosiveness.

Built by hand, built deliberately

Every Pasta Party 32โ€ณ frame is built by hand in our workshop in Saxony.

Design and fabrication happen side by side, which allows us to refine details that matter specifically for large wheels: clearances, alignment, mounting points and structural transitions. The frame is built with longโ€‘term use in mind, prioritizing consistency, reliability and ease of setup for real distances.

This is where the project moves from concept to usable tool.


A confident step into bigger wheels

The Pasta Party 32โ€ณ isnโ€™t about proving that bigger wheels are better. Itโ€™s about exploring where they make sense.

For riders who value momentum, stability and sustained efficiency over long distances, the 32โ€‘inch format opens up a different way of thinking about XC performance. Familiar in feel, different in how far it carries you.

An XCโ€‘focused endurance hardtail, engineered specifically around 32โ€‘inch wheels โ€“ efficient by design, composed by proportion.

Why 32″ at Sour?

The next big thing? Have a read about our thoughts to the new wheel size!

Over the past 10 years, the way people ride has changed. Routes have grown longer, surfaces more mixed and expectations less defined by categories. Riders move fluidly between pavement, gravel, forest roads and trails, often in a single ride โ€“ and increasingly over long distances.

As scale changes, so do priorities. Acceleration matters less than continuity. Agility matters less than stability. And over time, the effort it takes to keep a bike moving becomes the defining factor.

This is where 32โ€ณ wheels come to play.

Custom bikes – Painted in Dresden

We love custom colors on bikes. We’ve offered custom powdercoating, done right here in Dresden, since our very frist day of operation.

Every year with have two or three standard colors if you’re not interested in stressing out over the thousands of solid colors, fade, gradients, and pearls… but really, there’s nothing more fun than a frame in your own color!

We have a selection of custom colors, just to keep it a little simpler, but if you’re really looking for super duper custom colors, we’ve got that too.

Click below to learn more about custom colour and braze-on options.

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 in Germany 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.

By the numbers:

Headtube: ZS44/ZS56 (for tapered steerer tubes)
Bottom bracket: 73mm T47
Rear spacing: 148x12mm Boost thru axle
Seatpost: 31.6 mm (dropper post ready)
Brake standard: Post Mount 160mm direct (PM160)
Fork travel: 100 – 120mm travel
Wheel Size: 32″
Tire size: up to 32×2.4โ€
Tubing: Custom drawn, multiple butted, partly heat treated SOUR CrMo (we love steel)

Bonus facts and features:


Two water bottle mounts inside frame, a third bottle mount under downtube
External cable routing under the toptube for easy service
Stealth dropper post routing
Ovalized lower seat tube section for better power transfer (go fast)
Ovalized toptube for comfort and precise steering (don’t crash)
Maximum chainring size: 38t round or 36t oval
Sram Transmission Compatible Dropouts (“UDH”)

Below are the frame and fork weights for each size of the Sour Pasta Party. These weight do not include powdercoating, but please keep in mind that your chose powdercoat may be heavier than the average coating we use. Fades, gradients, and metallic colours can weigh more than single solid colour. If you are interested the final weight, please get in touch. Weights are averaged over three frames per size. We apply an inside wax coating before shipping the frame to your door that will add additional weight.

Frame without bolts, axle or
brake mount

Pasta Party 32 Frame Medium = 2325g +/- 100g

Included with your frame

Included with your Pasta Party frame or frameset is the derailleur hanger plus all cable guides. You get a rear thru-axle of course, and if you’re ordering a frameset, you get a front axle with your fork as well. Headsets are only included if you add one to your order.
