2025 Yeti SB135 TURQ Custom GX AXS (Demo | YDM260703)

About This Bike

This 2025 Yeti SB135 TURQ Custom GX AXS in Turquoise is a playful, aggressive trail bike built for riders who value precision, traction, and a lively ride character on technical terrain. The medium TURQ Series carbon frame combines 150mm of front travel with 135mm of Switch Infinity rear suspension, creating a bike that pedals efficiently but still encourages hard cornering, creative line choices, and confident descending. This custom example uses the premium T2 specification as its foundation while adding SRAM GX AXS Transmission, a OneUp dropper system, and Continental tires.

Condition Notes:

• Scratches on derailleur
• Chips on right side of rear triangle
• Chips on lower section of front triangle near cable port exit
• Scratch on inner front triangle just below bottom bottle cage bolt
• Scratches on fork decals
• Scuffs on both sides of fork lowers just below fork seals
• Scratches on both wheel rims
• Chip on rear triangle between both suspension pivot points
• Scratches on both crank arms

The SB135 uses Yeti’s TURQ Series carbon construction for both the front and rear triangles, delivering a stiff, responsive chassis with the low weight and refined ride quality expected from the brand’s top carbon level. Molded frame protection helps shield the down tube, chainstay, and seatstay from trail impacts, while internally tunneled cable routing keeps the frame clean and simplifies maintenance. The medium frame is built around a mixed-wheel platform, pairing a 29-inch front wheel with a 27.5-inch rear wheel for a balance of rollover and agility.

Yeti’s Switch Infinity suspension system manages 135mm of rear travel and is tuned to provide efficient pedaling support, strong mid-stroke control, and a progressive feel deeper in the travel. A Fox Float X Factory rear shock with Kashima coating offers adjustable damping and consistent performance through repeated hits. Up front, a 150mm Fox Float 36 Factory fork with GRIP2 damper provides the stiffness and control needed for aggressive trail riding, while remaining lighter and more responsive than a full enduro fork.

The drivetrain has been changed from the original specification to SRAM GX AXS Transmission. The hangerless T-Type architecture is designed for consistent shifting under load, while the wireless AXS controller removes the need for a conventional shift cable. A 10-52-tooth cassette provides the broad range needed for steep climbs and fast descents, and the matching GX T-Type crankset and chain create a complete modern drivetrain package suited to the SB135’s hard-riding intent.

SRAM Code RSC four-piston brakes provide powerful stopping performance with tool-free reach and contact-point adjustment. Large rotors help control heat on sustained descents and give the bike predictable braking in technical terrain. DT Swiss XM1700 alloy wheels offer a durable, serviceable platform with a width appropriate for aggressive trail tires, while the custom Continental tire setup replaces the original Maxxis specification throughout this listing.

A OneUp dropper post and OneUp dropper lever replace the original seatpost controls. The OneUp system is known for compact stack height, generous travel options, and a smooth lever feel, allowing the rider to quickly move the saddle out of the way for technical descents and jumps. The Yeti carbon handlebar, premium stem, and ergonomic contact points complete a cockpit intended to feel precise and controlled without muting the bike’s playful personality.

The SB135’s mixed-wheel configuration is a major part of its character. The 29-inch front wheel improves rollover and front-end confidence, while the 27.5-inch rear wheel shortens the bike’s response and makes it easier to change direction, manual, and move through tight terrain. Combined with the 150mm fork and 135mm rear travel, the result is a bike that feels energetic on rolling trails but still has enough composure for technical descents and aggressive riding.

For riders seeking a premium custom trail bike with wireless shifting, Factory-level suspension, a compact OneUp dropper system, and Continental tires, this 2025 Yeti SB135 TURQ Custom GX AXS offers a distinctive and capable package. Offered at $4,499 against a $7,400 MSRP, this Turquoise medium demo bike delivers top-level frame construction and modern components at a substantial discount, with all known cosmetic wear clearly documented above.
