Specialized Stumpjumper 15 Alloy 2025 Full Suspension MTB - White Mountains

Season:2025

Brand:Specialized

Code:42762395437114

You want a bike that lets you push harder and smile wider. The Stumpjumper 15 Alloy eats big hits and still pedals like a short‑travel trail bike. It feels planted through rough sections and playful when you want to flick it around. Climb smooth. Descend fast. Ride more.

Why geometry matters:

The geometry is tuned to give you big‑bike confidence without the bulk. A low bottom bracket and slack head angle keep the bike stable. The generous cockpit centres you for better traction and sharper corner control. It simply tracks where you point it.

Personalise your ride:

This frame lets you set it up for how you ride. Six geometry positions let you bias the bike toward stability or agility. You can keep a big‑wheel feel or swap in a 27.5" rear for a livelier, more playful setup. The bike adapts to you.

Balanced compliance and strength:

We built the M5 Alloy chassis to be stiff where you need it and forgiving where your hands meet the trail. The frame moves with you, not against you. It’s made to take seasons of hard use and keep performing.

Support that keeps you riding:

This bike is backed by long‑term care. Critical suspension pivots have a lifetime replacement to the original owner. In short: you can ride it hard and trust it will be ready next weekend.

Key Features:

  • M5 Alloy frame with integrated SWAT downtube storage and engineered chassis compliance
  • X-Fusion 02 Pro RL rear shock with adjustable rebound and lockout paired with RockShox Psylo Silver fork with Motion Control Damper
  • Six-position geometry adjustability; tune head angle and bottom bracket; aftermarket link supports 27.5" rear or full big‑wheel setups without altering geometry
  • Shimano Deore 12-speed drivetrain for reliable, wide-range shifting
  • Shimano MT-420 4-piston brakes for confident stopping power
  • Kinematics tuned for balanced anti-squat and efficient pedalling
  • Durable build with lifetime replacement suspension pivot bearings for the original owner and ongoing support programs

Get out and ride it. You'll feel the difference.

S-Sizing
The Stumpjumper’s S-Sizing is based on what matters: rider size and style, not inseam. Six sizes, all with similar headtube lengths and standovers, allow you to choose the size that best suits your individual style. Smaller S-Size numbers are more nimble, thanks to their shorter reach and front centre measurement, while bigger S-Sizes deliver more stability and a roomier ride.

Find Your S-Size
Determining your S-Size is easy. If you rode a Medium before, then S-3 will be your equivalent size. But if you want a more nimble ride, you should drop down to an S2. Want a bike that’s more stable at speed? Bump up to an S4. The following are examples of three riders, all 5’8” (1.73m), who chose three different sizes.
