Giant XTC Advanced SL Frameset 2025 Bike

Build the lightest cross-country weapon in the Valley with the Giant XTC Advanced SL Frameset.

This is Giant's top-tier carbon hardtail frameset, built for XC racers and fast trail riders who count every gram. The XTC Advanced SL is the platform serious competitors build up for race day, whether you're hunting KOMs in the Santa Monica Mountains or lining up for a local XC series. It's a frameset, so the build is yours to spec.

It's right for you if:

• You race or ride cross-country and want the lightest, stiffest hardtail Giant makes.

• You have a specific drivetrain, fork, and wheel build in mind and want a premium canvas for it.

• You're upgrading from an alloy hardtail and want a real step up in acceleration and climbing.

Why you'll love it:

• Advanced SL carbon is Giant's lightest, so the bike snaps forward the instant you stand and sprint.

• Race-tuned XC geometry keeps you fast and precise through tight, technical singletrack.

• 29-inch wheel clearance rolls over roots and rock so you carry momentum on rough climbs.

• A stiff front triangle puts your power straight to the trail with no wasted flex.

The tech you get: a top-tier Advanced SL-grade full-carbon XC hardtail frame with 29er wheel compatibility and modern trail-tuned race geometry. Frame only, ready for your build.

Highlights

Pro-grade carbon foundation

This 29er hardtail frameset is built from Giant's Advanced SL composite, the same professional-grade carbon its race team rides. Start your XC build on a frame that won't hold you back.

Steering you can trust at speed

The OverDrive oversized fork steerer stiffens the front end for precise, direct handling. Pick your line through rock and root and hold it.

Modern XC clearances

A 12x148mm thru-axle and clearance for 2.25-inch tires keep the rear end stiff and race-ready. Build it light and fast for cross-country miles.

Room to spin your gearing

The frame accepts up to a 38-tooth chainring, giving you top-end speed on fast fire roads. Configure the drivetrain around how you race.
