2025 Yeti SB165 C3 GX Transmission

The 2025 Yeti SB165 C3 GX Transmission is a serious tool for anyone who rides hard, digs steep lines, and needs gear they can rely on. It offers no fluff, just thoughtful design that works. At the heart of the bike is Yeti’s C/Series carbon frame. It holds up when the trail gets gnarly without weighing you down. The frame geometry leans into stability with a slack head angle and a low bottom bracket, helping the bike stick through rock gardens and tight turns. Plus, Yeti’s Switch Infinity suspension makes climbs smoother and gives you plush control when gravity pulls you downhill.

Suspension

The Fox setup here is spot on. Up front, a Fox Performance 38 fork with 170mm of travel and beefy 38mm stanchions takes big hits and keeps steering sharp. In the rear, the Fox Factory DHX2 coil shock offers 160mm of travel and a supple feel that stays consistent, even on long, rough descents. Together they make the bike controllable, even when things get more technical than you expected.

Drivetrain

Shifting is where the wireless SRAM GX Eagle AXS Transmission shines. There are no cables to catch or stretch, just fast, clean, and precise shifts whether you’re hammering uphill or ripping downhill. The derailleur changes gears right on cue, and the AXS pod controller fits comfortably under your thumb with customizable feedback. The 30T carbon crankset offers efficiency and strength without excess weight, and paired with the 10-52T cassette, you get a gear range that helps you climb steep pitches or let loose going down. The chain is built to keep everything smooth and strong, matching the system perfectly.

Brakes

You'll also find a set of SRAM’s Code R brakes and 200mm Centerline rotors. These brakes have strong, consistent bite and modulation so you can dial in your speed exactly. Whether you’re dropping into a steep face or navigating tight corners, they give confidence.

Wheels and Tires

Rolling underneath, the DT Swiss E1900 wheelset holds up to gnarly riding with 30mm internal rim width, providing solid support for wide tires. The Maxxis tire combo features a front Assegai 2.5 EXO+ that grips corners and rocky patches like a champ. The Minion DHR II 2.4 DD out back focuses on braking traction and durability, so you won’t second-guess your tire choice on rough trails.

Handlebar and Controls

The cockpit setup favors control and comfort. A wide Burgtec Alloy Enduro handlebar offers stability, paired with a stout Burgtec Enduro MK3 stem. Odi Elite Pro grips keep your hands comfortable and secure even when the trail gets long and rough. The OneUp dropper post adjusts quickly to whatever terrain you face, with travel options that fit many rider styles and sizes.

Other Parts

Other parts round out the build: a Cane Creek 40 headset keeps steering smooth, a WTB Silverado saddle balances comfort and weight, and an MRP AMG SL bash guide protects your chainring when the trail gets technical.

This bike is built for serious trail riders who want a dependable, high-performing machine that handles technical climbs and aggressive descents with equal confidence. There are no gimmicks, just the parts and design to get you down the trail faster and freer.
