Product details

IN STORE PICKUP OR LOCAL DELIVERY ONLY

The tech-heavy lines through Black Knight and Spion Kop reward a bike that likes to play as much as it likes to charge. The Trek Fuel MX 9 Eagle 90 pairs an Alpha NEXT Platinum aluminum frame with 160mm of Fox Factory front travel and 150mm out back, plus mixed 29"/27.5" wheels for a stable front end and a flickable, nimble rear — all backed by SRAM's Eagle 90 T-Type drivetrain and Maven Bronze 4-piston brakes for confident stopping power when the trail gets rowdy.

 

 

KEY FEATURES

Frame: Alpha NEXT Platinum aluminum frame with internal storage, a zero-stack (ZS) integrated headset, an adjustable leverage-rate flip chip, and adaptable travel from 145mm to 160mm

Fork / Rear Shock: Fox Factory 36 fork with Float EVOL air spring and GRIP X2 damper (160mm travel), paired with a Fox Factory Float X rear shock (150mm travel)

Drivetrain: SRAM Eagle 90 T-Type 12-speed shifter and derailleur (hanger-free, direct-mount), SRAM Eagle 90 DUB crank (30T), SRAM Eagle XS-1275 10-52 cassette

Brakes: SRAM Maven Bronze 4-piston hydraulic disc brakes with SRAM HS2 rotors (200mm front, 180mm rear)

Cockpit: Race Face Turbine alloy handlebar (780mm width, 40mm rise), Bontrager Elite stem, and a Bontrager Line dropper post (150–200mm travel depending on size)

Standout feature: SRAM's hanger-free T-Type Transmission mounts directly to the frame for a cleaner, more precise, and easier-to-set-up drivetrain

WHO IS THIS FOR?

This bike suits an intermediate-to-advanced rider who wants a playful, poppy trail bike for carving corners and hunting technical lines through terrain like Black Knight and Spion Kop, without giving up serious capability when things get steep or fast. They'll appreciate the mixed-wheel handling, the strong Maven Bronze brakes for confident descending, and SRAM's tool-free Transmission shifting that stays consistent under load.

Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

HOW TO SET UP

Our team can set your sag, rebound, and compression on both the Fox 36 fork and Float X shock to match your weight and riding style, and walk you through the flip-chip leverage rate adjustment for more or less progressive support. We'll route and set up your Bontrager Line dropper post for full use of its travel, and get your tyres set up tubeless with the right pressure front and rear for the mixed-wheel setup. We also offer ongoing suspension servicing and SRAM Transmission maintenance as your riding progresses. Drop into Fresh Air Pandosy (555 Groves Ave) or Fresh Air Dilworth (1656 Dilworth Drive), or book an appointment online.

FAQ

Q1: What size Trek Fuel MX 9 Eagle 90 do I need?
The Fuel MX 9 Eagle 90 comes in four sizes — S, M, L, and XL — with dropper post travel and cockpit dimensions scaled to fit. General sizing follows your height and riding style, but the best way to confirm your size is an in-person fit — our team at either Kelowna location can get you set up correctly.

Q2: Is the Fuel MX 9 Eagle 90 right for Black Knight and Spion Kop trails?
Yes — with 160mm/150mm of travel, aggressive Maxxis Assegai and Minion DHR II tyres, and powerful Maven Bronze brakes, the Fuel MX is well suited to the technical, rowdier lines found on Black Knight and Spion Kop.

Q3: How do I set up the suspension on the Fuel MX 9 for my weight and riding style?
Suspension setup starts with sag — typically 25–30% on the fork and shock for aggressive trail riding — then fine-tuning rebound and compression to your weight and terrain preference. The Fuel MX also has a flip chip in the lower shock mount to adjust leverage rate for a more or less progressive feel. Our team can walk you through all of this and get your suspension properly dialled in-store.
