Altera G21 Color Guide: Choose Your Gravel Frameset

Four colors, one platform, zero performance compromise

Every Altera G21 frameset delivers identical engineering regardless of color. The same Toray 800 high-modulus carbon fiber, the same 980g frame weight (±50g at 49cm), the same T-47 threaded bottom bracket, the same 53mm tire clearance, and the same 6-year warranty. Paint does not change the carbon layup, the geometry, or the structural performance. It changes how your bike looks standing against a wall, leaning on a tree at a trailhead, or rolling through a finish line.

That said, aesthetics matter. Riders who spend $1,420 on a frameset—and then invest further in groupset, wheelset, saddle, and cockpit—deserve a color they genuinely want to look at for years. The Altera G21 currently ships in four stock colorways: Artisan Black, Prizm Blue, Panda Purple, and Champagne. A fifth option—fully custom paint—starts at +$300 for riders who want something uniquely theirs.

This guide breaks down each color option with practical considerations: finish type, visual characteristics, component matching, and which riding contexts each color suits. All four stock colors ship at the same $1,420 price point with no upcharge between them.

What every Altera G21 includes, regardless of color

The Altera G21 platform has been tested to 100,000 pedaling fatigue cycles at 1,100N, 50,000 vertical fatigue cycles at 1,200N, and impact-drop tested with 22.5kg from 21.2cm height. These numbers exceed the ISO 4210 minimums and reflect Yoeleo’s internal testing protocol. The same frame platform won the women’s category and took third in the men’s field at the 2025 BOLERO UCI Gravel World Championships.

The four stock colorways compared

All four colors use Yoeleo’s standard paint process applied over the UD carbon weave. Decal color options (Silver, White, or Black) are available across all colorways to fine-tune the final look. Each color ships from the same production line with the same lead time.

Artisan Black	Prizm Blue	Panda Purple	Champagne
Deep, clean black with subtle UD carbon texture visible under direct light	Metallic blue with prismatic depth shift under changing light angles	Deep purple with dark-to-light transition; collaboration colorway	Warm gold-neutral tone with understated metallic finish
Pairs with virtually any component color	Pairs best with silver, black, or white components	Pairs well with black, silver, or contrasting components	Pairs naturally with black, brown, or earth-toned components
Shows dust and scratches most visibly	Moderate scratch visibility; hides trail dust well	Good scratch concealment at darker tones	Best scratch and dust concealment of the four

Artisan Black: the versatile default

Black remains the most popular frameset color across the cycling industry for a reason: it matches everything. Artisan Black on the Altera G21 is not a flat matte black—it is a refined finish that allows the underlying UD carbon fiber weave pattern to show through under direct sunlight or studio lighting. This gives the frame a technical, purposeful appearance that communicates “performance tool” rather than “generic frame.”

From a practical standpoint, Artisan Black is the most versatile option for component matching. It pairs equally well with silver Shimano GRX components, black SRAM AXS groupsets, chrome accessories, or colorful bar tape and saddles. Riders who swap components frequently or plan to evolve their build over time will appreciate that black never clashes.

The trade-off: black shows road dust, dried mud, and surface scratches more readily than lighter or metallic finishes. For gravel riding where the bike accumulates trail debris regularly, expect to wipe down the frame more often to maintain its clean appearance. A frame protection film (such as RideWrap or Shelter) is worth considering for high-impact zones—the chainstay, down tube, and head tube area.

Best for: riders who want maximum component flexibility, a timeless aesthetic, or plan to add colorful accents through bar tape, saddle, and accessories.

Prizm Blue: the statement maker

Prizm Blue is the most visually dynamic of the four stock options. The metallic pigment shifts tone depending on the angle of light—appearing deeper in shade and more vivid in direct sunlight. This prismatic quality means the frame looks different at every angle, which photographs exceptionally well for social media or event coverage.

Blue is also one of the most common accent colors in cycling components. Yoeleo’s own brand color palette centers on blue (the “BLOVE” blue family), making Prizm Blue a natural complement to Yoeleo-branded accessories. Beyond brand alignment, blue contrasts effectively against natural landscapes—green forests, brown singletrack, grey rock—giving the bike strong visual presence in outdoor photography.

For component matching, silver or polished aluminum components complement the blue without competing for attention. Black components create a more aggressive, stealthy look. Avoid pairing with red or orange components, which can clash with the blue’s cool-spectrum tonality.

Best for: riders who want their bike to stand out in a group, photograph well, or align with Yoeleo’s brand identity. Particularly striking with silver decals.

Panda Purple: the distinctive choice

Panda Purple is a collaboration-inspired colorway that occupies a unique position in the gravel frameset market. Purple is rare in cycling—most manufacturers default to black, grey, blue, or red. This rarity means a Panda Purple G21 is immediately identifiable at any gravel event or group ride. For riders who value individuality, this matters.

The purple finish uses a dark-to-light tonal range that keeps the overall appearance sophisticated rather than loud. In low light or at a distance, the frame reads closer to a deep burgundy-black. In bright sunlight, the purple becomes more pronounced and distinct. This dual personality makes it appropriate for both casual riding and serious gravel racing.

Component matching is more considered with purple but far from limiting. Black groupsets and black accessories create a clean, cohesive look. Silver components add contrast. For riders comfortable with bolder aesthetics, gold or bronze touches (such as a tan leather saddle or gold chain) can elevate the build into something genuinely distinctive.

Best for: riders who want a frameset that stands apart from the typical black/grey/blue options available from every other brand. Works well with black decals for subtlety or white decals for contrast.

Champagne: the understated premium

Champagne occupies the warm, neutral territory that has gained significant traction in cycling and automotive design over the past two years. The finish carries a subtle metallic quality with gold and warm grey undertones—distinctly different from the cooler silver or titanium finishes common on other framesets.

In practical terms, Champagne is the most forgiving of the four colors for daily riding. Light scratches, trail dust, water spots, and minor scuffs are far less visible on a warm metallic surface than on Artisan Black or Prizm Blue. For riders who use their gravel bike as a true working tool—commuting, loaded touring, wet-weather riding—this translates to less aesthetic maintenance.

Component matching with Champagne favors earth tones and warm metals. Black components and accessories look clean and intentional. Brown leather saddles, tan bar tape, and brushed metal accessories create a classic adventure aesthetic that photographs beautifully against natural landscapes. Chrome or polished silver can also work, though the warm-cool contrast is more noticeable.

Best for: bikepacking builds, adventure-oriented riders, or anyone who prefers a warm, understated aesthetic over bold primary colors. Excellent for riders who ride in all conditions and want a finish that ages gracefully.

The fifth option: custom paint

For riders who want a color or design that does not exist in the stock lineup, Yoeleo offers custom paint starting at +$300 above the base frameset price. This brings the total frameset cost to $1,720 or more depending on design complexity.

Custom paint options include glossy or matte finishes, single-color applications, gradation (smooth color-fade between two colors), cut designs (geometric color blocking), and fully bespoke designs created in collaboration with Yoeleo’s design team. Decal colors (Silver, White, Black) can be specified independently of the paint scheme.

The custom paint process adds approximately 50 days to the order-to-shipment timeline. This reflects the additional design consultation, painting, quality inspection, and curing time required for a one-off finish. Yoeleo sends photos of the finished frame before shipping, allowing you to confirm the result matches your expectations.

Important note: custom paint adds 15–40g to the frame weight depending on design complexity and finish type. For context, the standard Artisan Black finish adds approximately the same amount as any stock color. The weight difference between a custom-painted and stock-painted frame is negligible in real-world riding.

Does paint color affect frame weight?

This is a legitimate question that performance-focused riders ask. The answer: yes, technically, but the difference between stock colors is negligible—within the ±50g manufacturing tolerance already specified for the frame weight.

Different pigments and finishes have marginally different densities. Metallic finishes (Prizm Blue, Champagne) carry slightly more pigment weight than a solid black. Multi-layer finishes add marginally more clear coat. In practice, the weight variation between any two stock Altera G21 colors is estimated at 5–15g—well within the frame’s stated tolerance and undetectable in riding performance.

For reference, 10g is approximately the weight of two standard cable end caps. If frame weight is your primary concern at this level of precision, the raw carbon (unpainted) frameset is the lightest option—but the Altera G21 is not currently offered in a raw finish.

How does the Altera G21 compare on value?

Color selection is part of a broader purchase decision. Here is where the Altera G21 sits in the current gravel frameset market, based on publicly listed prices as of early 2026:

Frameset	Price	Frame Weight	Tire Clearance	Colors
Altera G21	$1,420	980g (49cm)	53mm (1x)	4 + custom
Canyon Grail CF	~$2,000+	~1,050g	42mm	2–3
Specialized S-Works Crux	~$5,500+	~790g (frame)	47mm	2–3
Cervelo Aspero	~$3,000+	~1,000g	45mm	2–3

At $1,420, the Altera G21 includes the integrated H21 handlebar (340g, 15.2° flare) and Pro-Flex seatpost—components that most competitors charge $300–$500 extra for or do not offer at all. The included cockpit and seatpost narrow the effective price gap further. Combined with 53mm tire clearance (significantly wider than the Canyon Grail’s 42mm), integrated in-frame storage, and the T-47 threaded bottom bracket that eliminates the creaking and alignment issues associated with press-fit BBs, the G21 delivers substantial specification advantages at its price point.

This value context matters for the color decision because it means your budget savings on the frameset can be redirected toward the build—a better groupset, lighter wheels, premium tires, or a professional bike fit—rather than being absorbed by the frame cost.

Which color should you choose? A decision framework

If you are unsure which color to select, these practical questions can help narrow the decision:

What components will you build with? If you already own a groupset and wheelset in specific colors, start by matching the frame to what you have. Artisan Black matches everything. Champagne and Prizm Blue pair best with specific palettes.
How much trail debris will the bike see? If you ride in mud, dust, or wet conditions frequently, Champagne hides daily wear best. Artisan Black shows it most.
Do you want the bike to blend in or stand out? Artisan Black and Champagne are understated. Prizm Blue and Panda Purple are distinctive. Neither approach is better—it depends on your preference.
Are you planning to resell in the future? Neutral colors (Artisan Black, Champagne) historically hold resale value better than niche colors in the cycling market—though resale should not be the primary driver for a bike you plan to ride hard.
Do you want something no stock option offers? Custom paint (+$300, ~50 days added lead time) opens the design entirely. Gradation fades, geometric cut patterns, or fully bespoke artwork are available.

Frequently asked questions

Is there a price difference between the four stock colors?

No. All four stock colorways—Artisan Black, Prizm Blue, Panda Purple, and Champagne—are priced identically at $1,420. The only upcharge is for custom paint, which starts at +$300 above the base price.

Can I change the decal color on my frameset?

Yes. Decal color options include Silver, White, or Black, and can be selected independently of the frame color when ordering. Different decal colors meaningfully change the visual character of the same paint finish—for example, Artisan Black with white decals looks more visible and graphic, while black decals on Artisan Black create an ultra-stealthy look.

Does color affect the weight of the frameset?

The weight variation between stock colors is 5–15g—well within the frame’s stated ±50g manufacturing tolerance and undetectable on the road. Custom paint may add 15–40g depending on complexity. For a frameset weighing approximately 980g, even the maximum variance represents less than 4% and has no measurable impact on climbing or acceleration performance.

How long does custom paint take?

Custom paint adds approximately 50 days to the standard lead time. This includes design consultation, painting, quality inspection, curing, and pre-shipment photo confirmation. The process is documented—Yoeleo sends photos of the finished frameset before shipping so you can approve the result.

Will a frame protection film work on all colors?

Yes. Transparent frame protection films (such as RideWrap, Shelter, or equivalent) work on all four stock finishes and on custom paint. We recommend applying protection to the chainstay, down tube, and head tube area regardless of color—these are the highest-impact zones on any gravel build. Protection film is particularly valuable on Artisan Black and Prizm Blue, where surface scratches are more visible.
