Between each cog, Altered Cycle CNC-machined oblique channels called "ZIP Ramps." When you shift under full power (up to 1,200 watts), these ramps use centrifugal force and chain tension to pull the chain into the next gear rather than pushing it. The 2021 revision widened these ramps by 0.15mm compared to the 2019 model, solving early complaints of skipped shifts in wet mud.
The Altered Cycle ZIP 2021 represents a fork in the road for drivetrain design. While the rest of the industry chased wireless, app-controlled, servo-driven shifting, Altered Cycle doubled down on physics, metallurgy, and raw tactile feedback. It is flawed, heavy, and noisy—but it is also the most reliable mechanical shifting system ever built for high-power riding.
Whether the brand ever returns to production remains a mystery. For now, the 2021 ZIP lives on as a testament to what happens when engineers refuse to follow the herd. If you see one for sale, grab it. Just don’t forget to buy the chain.

When the Altered Cycle ZIP 2021 launched in April 2021, the cycling world was in the midst of the COVID-19 component shortage. This was both a blessing and a curse. altered cyle zip 2021
By December 2021, Altered Cycle announced they were pausing production to retool for a 2023 model (which, as of this writing, has not yet shipped). This made the ZIP 2021 an instant collectible.
In the world of high-end cycling, the drivetrain is the soul of the machine. By 2021, the market was saturated with electronic shifting—SRAM AXS and Shimano Di2 dominated the peloton. But a small, rebellious brand from the Pacific Northwest, Altered Cycle, decided to go the other way.
Enter the Altered Cycle ZIP 2021—a mechanical, continuous-loop, belt-drive compatible shifting system designed to mimic the tactile feel of a precision rifle bolt-action while offering the lowest maintenance profile on the market. The “ZIP” refers to the sound and speed of its rear cassette engagement, which, according to early testers, sounds like tearing a piece of tape at 50 mph.
This article explores every facet of the 2021 model: its engineering, unique selling points, failures, and why it remains a cult classic three years later.
Product Category: Cycling Apparel (Winter / Deep Winter Jersey) Manufacturer: Altered (Italian brand) Season: Fall/Winter 2021 MSRP (2021): Approx. €160–€190
Most bicycle cassettes use a ramped, hyperglide design. Shifting pushes the chain from a smaller cog to a larger one via pins and cutouts. The Altered Cycle ZIP 2021 threw that playbook away.
Several brands are known for their innovative approach to cycling and urban fashion. While not an exhaustive list, brands like:
The Altered Cycle ZIP 2021 is for the performance-oriented winter rider who rides hard enough to generate internal heat. If you are a commuter standing around at traffic lights or a leisure rider averaging 15km/h, you will feel cold. If you are doing 3-hour base miles or winter intervals, this is one of the best thermal jerseys of the 2021 season.
Bottom Line: Altered corrected the durability flaws of the 2020 model and refined the breathability. While newer models have since been released, a well-cared-for 2021 ZIP remains a benchmark in the "thermal jersey" category.
The year was 2021, and the "Compliance 101" course was Elara’s masterpiece. She had spent months building intricate triggers, branching scenarios, and custom variables. When the final version was approved, she packaged it neatly into a file named Compliance_Final_2021.zip and sent it into the corporate abyss.
Fast forward to today. A single regulation changed. The "2021" version, once the gold standard, now needed a simple three-sentence update. Elara’s successor, Marcus, found the file in the archives. "Just open the .zip and change the text," the manager said.
But Marcus knew the truth. He looked at the altered cyle zip and saw not a project, but a ghost. Inside were thousands of tiny pieces—JavaScript snippets, compressed images, and XML bones—but the "soul" of the course, the .story file, was missing. It was like trying to un-bake a cake to change the amount of sugar.
He tried the old trick: renaming the extension, hoping it was just a disguised source file. Compliance_Final_2021.story
Error. The screen stayed blank. The logic was locked away in 2021.
Marcus sighed and opened a fresh, empty project. He began to copy the text from the published version, rebuilding the triggers one by one. The 2021 zip sat on his second monitor—a perfect, unchangeable relic of a cycle that had finally come to an end.
