Pre-Launch

Specialized Stumpjumper Comp Alloy Mountain Bike in Satin Cast

Season:2023

Brand:Specialized

Code:300706313675

Don't worry metal fans, the Specialized Stumpjumper Comp Alloy is still alive and well, and with one of the most advanced alloy frames ever developed. With its asymmetrical design, all-new geometry, refined kinematics, and a build kit that strikes the optimal combination of performance and value, it's ready to hit the dirt.

Key Features:
  • Asymmetrical Design Alloy Chassis and Rear-End Frameset
  • FOX FLOAT DPS Performance, Rx Trail Tune 130mm Rear Shock
  • FOX FLOAT 34 Rhythm, 140mm Fork
  • X-Fusion Manic Dropper Post
  • SRAM G2 R, 4-Piston Caliper, Hydraulic Disc Brakes
  • SRAM NX Eagle, 12-Speed Gears
  • Tubeless Ready Wheelset

The Trail Benchmark
When Specialized set out to design the all-new Stumpjumper, they pursued some hefty goals. They went after the lightest-possible weight that sacrifices nothing to durability, a stiff chassis that corners on rails, and a geometry that everyone can enjoy, all with the best suspension kinematics we know how to design. Turns out, you can have your cake and eat it too with the new Stumpjumper.

Progressive Geometry
The S-Sizing geometry of the new Stumpjumper hits the progressive sweet spot. Long, low, slack, a short offset fork, a steeper seat tube angle—they’re all the talk of the town because they make your ride better. With Flip Chip adjustability you’re able to further fine-tune your fit, ensuring that your new Stumpjumper performs flawlessly on whatever terrain you choose.

S-Sizing
The time has come to ditch S-MD-LG sizing. S-Sizing delivers six sizes, all with similar headtube lengths and standover, to allow your riders to choose the size that fits their style, instead of their inseam. Smaller sizes are more nimble, while bigger sizes are more stable and roomier.

Click & Collect Orders

Please be aware Click & Collect orders may take some time to fulfil. We advise not to travel to your chosen store until you have been notified that your order is ready for collection.

Spread the cost of your new bike, helmet, safety equipment and accessories paying via instalments being taken directly from your wage. The payments for the Cycle To Work scheme are taken out of your gross wage and your Tax & NI contributions are then worked out based on your new lower gross wage which is how you save money on your new bike and equipment.

At the end of the time period specified with your Cycle To Work scheme you then have the option of buying your bike or to continuing to use it while you work for the company. If you decide to purchase the bike, the balance you owe will be based on a percentage of how much the bike was worth at the time you took out the Cycle To Work scheme.

We know how eager you'll be to jump on your new bike and hit the dirt or tarmac, so we give you everything you need to get you set up quickly. For full instructions on how you're bike will arrive and what you'll need to do, visit our How Our Bikes Are Built page
