Anthem Advanced 29 3 (2025)

The Anthem Advanced 29 lineup is built entirely around Giant’s Advanced-grade carbon frame, meaning riders get the same lightweight FlexPoint Pro chassis regardless of the price point. The primary dividing line in the build ladder is the suspension technology. Upper-tier models feature Fox Live Valve electronic suspension, which automatically toggles damping settings based on trail inputs. These premium builds typically include carbon wheelsets and high-end Shimano or SRAM drivetrains, catering to racers seeking maximum automated efficiency.

Lower down the ladder, models like the Anthem Advanced 29 3 rely on traditional, cable-actuated suspension. This specific build pairs a RockShox SID Base fork with a custom-tuned SidLuxe Select+ rear shock, utilizing a manual remote lockout for sprints and smooth climbs. The drivetrain mixes reliable Shimano Deore and SLX 12-speed components with a Praxis crankset, prioritizing functional durability over absolute weight savings. Rolling stock on the entry-level builds shifts to Giant’s XCT alloy rims with a 25mm internal width, wrapped in high-volume Maxxis Aspen tires. While these mechanical builds lack the automated wizardry and carbon hoops of the flagship models, they offer a much simpler maintenance profile and deliver the exact same modern geometry and structural stiffness at a more accessible price.

Reviewers consistently note that the updated Anthem Advanced 29 trades the nervous energy of older cross-country bikes for a highly composed, calculated ride feel. At high speeds and on steep chutes, the chassis feels "notably more solid and surefooted" (Flow Mountain Bike) than its predecessor. The suspension is supple off the top, effectively muting trail chatter, while the stiffened bottom bracket area ensures immediate power transfer during hard efforts.

This stability comes with minor handling tradeoffs. In tight, flat hairpins, the longer wheelbase and slacker front end require a more deliberate steering input, and the single-pivot rear suspension is slightly less active under heavy braking than the outgoing dual-link design. However, testers found that the active rear end allows the tires to "scrabble for every ounce of grip" (Allcarbontube) on loose, technical ascents.

On descents, the bike rewards an aggressive riding style. The geometry and suspension work together to keep the chassis stable, effectively "breaking down each section of the trail into manageable pieces" (Bike Perfect). While models equipped with electronic suspension systems received praise for their seamless pedaling platforms, some testers noted that the automated firm settings require the rider to push hard to open the valves, which can feel harsh during fatigued, low-speed efforts. Overall, the consensus points to a highly capable race bike that excels when pushed hard on demanding terrain.
