Description
Altera: Gravel From The Future
What's New
More storage, more flexible, more comfort, more control and more of everyhing. If G21 has the answer to your questions, the G21 Alterra has the answer and more.
Refined Gravel-Optimized Geometry
Slacker headtube angle, longer wheelbase, and a shorter stem come together for better stability and control on rough terrain—without the worry of toe overlap.
Integrated Storage Solutions
Internal storage compartments on the top tube and down tube (with a built-in bag) let you pack more gear for extended rides or simply stash a day’s worth of essentials directly in your frame.
Generous Tire Clearance
Supports up to 700x53mm or 650Bx2.1” tires (single chainring). From fast gravel to rugged trails, Altera adapts to the ride you want.
Premium Detailing and QC
Careful quality checks and a clean, high-level paint finish give you the kind of value you don't usually find at this price.
UDH Compatibility & Optimization
The Universal Derailleur Hanger (UDH) adds an extra layer of security and flexibility. Ride confidently knowing your derailleur and frame are protected, and choose any groupset you prefer with UDH’s universal fit.
Introducing the Yoeleo Pro-Flex Seatpost
Now featuring a 27.2mm round profile, the Pro-Flex Seatpost quickly absorbs road buzz for improved comfort. The round design also makes it easy to switch to a third-party seatpost if desired—or even upgrade to a dropper seatpost. This change from the previous D-shaped configuration opens up more possibilities for every rider.
Re-Engineered BB Shell
A threaded bottom bracket made from bonded aluminum is now molded into the frame—offering perfect alignment, improved durability, and a lighter overall build for a smoother ride experience.
Flared Cockpit System
With a 15.2° flare and widths from 400 to 440mm, H21 CARBON INTEGRATED HANDLEBAR offers better control and all day comfort. Perfect for gravel, adventure, and aggressive terrain.
