Product Description

Fast, nimble and fun to ride. The Specialized Stumpjumper ST Alloy is a women’s specific short travel full sus MTB. Built for rapid riding on those trails where you don’t need the suspension travel of an enduro bike you will have more fun on the Stumpjumper ST.

Key Features:

  • High-quality M5 aluminium alloy frame with 120mm rear wheel travel & dialled trail geometry
  • RockShox Recon fork offers 130mm of trail taming suspension travel
  • Shimano SLX 1x11 speed drivetrain for a wide ger range and reliable running
  • Hydraulic disc brakes for powerful speed control
  • Sizes: X Small, Small, Medium, Large
  • Colour: Grey Black
  • The Specialized Stumpjumper ST Alloy Women's is available with 0% APR finance

Yes, the new Women's Stumpjumper ST 27.5 comes as an alloy version, and it may be the most radically designed alloy bike ever made. And with new tube shapes, an asymmetrical design, and the snappy handling that the 27.5 platform is known for, this bike is sure to exceed your expectations of how a trail bike should ride.

Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialling-in the materials, shapes, and the layout.

We continued down the suspension path with a Women's Rx Tune that gives both the fork and rear shock a custom tune specifically for female riders. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Women's Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform and rider size. So, no matter what, you'll get perfectly linear suspension.

Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0" tire. You're also free to run whatever aftermarket rear shock you want, since we're using standard metric shocks. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain.

The build here is no-nonsense with a focus on dependable, high-performing parts, like Shimano SLX front and rear derailleurs, Tektro Gemini disc brakes, a RockShox Recon RL fork with 130mm of travel, a custom X-Fusion 02 Pro RL rear shock with 130mm of travel, and wide alloy wheels.

Highlights:

The all-new alloy Women's Stumpjumper ST frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 27.5 Trail Geometry, so it's both capable and comfortable.

The X-Fusion Metric rear shock features rebound adjustment, lockout, and our coveted Rx Trail Tune to ensure you're getting the most out of your Stumpjumper ST.

A RockShox Recon RL provides 130mm of travel up front, and it lets you adjust both rebound and lockout.

Full Sus MTB Guide

 

Is a full-suspension mountain bike right for me?

If you’re new to the world of cycling, we highly recommend taking a look at our bike buying guide overview or our mountain bike buying guide to help you decide what type of bike is right for your needs.

When you’re choosing a full suspension mountain bike, there are a few things to look out for which can help you to work out the quality and performance you can expect from a particular model.


Suspension travel & usage

Depending on the type of mountain bike riding you’ll be doing, you may want to have longer or shorter suspension travel on your bike:

Travel

Usage

Pros

Cons

Up to 120mm

XC

Lightweight & efficient pedalling for long-distance rides

Short travel is less capable on rough & demanding trails with large jumps & drops

120 – 150mm

Trail

Lightweight, balance of climb-friendly efficiency & rough-descent capability

More weight than a shorter travel bike & less efficient climbing. Less capable on descents than a longer travel bike

150-180mm

Enduro

Capable of covering difficult & technical downhill sections. Wide enough gear range for climbing

Heavier & significantly less efficient at climbing compared to shorter travel bikes

180mm +

Downhill

Designed for highly technical & high-speed descents, with big drops and large jumps

Heavy, and inefficient at climbing. Limited gear range means most climbs will require pushing the bike


Frame material

Full-suspension MTB frames are mostly made from either aluminium or carbon fibre, with each material having its own benefits & drawbacks.

Aluminium

Aluminium is lightweight, stiff, strong, and easy to manufacture. Manufacturers often develop their own aluminium alloys, such as ALUXX by Giant. Aluminium is found on a wide range of bikes, from entry-level & enthusiast bikes, right the way up to top-spec racing bikes.

Carbon

Carbon fibre is lighter, stiffer, stronger, and more expensive than aluminium. The most affordable carbon bikes typically use medium strength carbon fibres, while the most expensive bikes use stronger ‘high modulus’ carbon. Carbon fibre frames are found on enthusiast-level bikes, right up to high-performance bikes designed for racing.


Groupset & drivetrain

A bike’s groupset, or drivetrain, is where the biggest difference in component quality is seen.
A complete groupset comprises of the following parts:

  • Chainset (aka Crankset)
  • Bottom bracket
  • Brakes
  • Brake levers
  • Shifters
  • Front & rear derailleur
  • Chain
  • Cassette
MTB Groupsets

Mountain bike groupset components are typically supplied by either Shimano or SRAM, with additional manufacturers like Formula, Hope, Magura, Tektro and TRP supplying brake systems. Shimano & SRAM both produce a range of groupsets to suit different budgets. The hierarchy table here compares the different Shimano & SRAM groupsets to determine which bikes offer the best performance.


Wheel size

You’ve probably noticed that a lot of mountain bikes come in a choice of wheel size, mainly a 27.5 inch wheel (also known as a 650B wheel) or a 29inch wheel (known as a 29er). Although there are still bikes which use 26 inch wheels, these are gradually being phased out on all but the smallest bikes. The difference between these wheel sizes can have a dramatic effect on the way a bike feels and handles out on the trail.

27.5in/650b Wheels

27.5inch wheels are smaller and lighter than 29er wheels, which makes them more agile and gives the bike a more responsive & playful nature. On the other hand, the smaller wheel size rolls less efficiently than the larger size, making the bike more prone to losing speed over rough ground and making it a little slower when climbing.

29er Wheels

29er wheels have a bigger rolling radius which makes them naturally smoother over rough ground. For this reason, a 29er mountain bike often requires less suspension travel than smaller wheeled alternatives. The downsides are an increase in weight, and the larger diameter wheels generate stronger gyroscopic forces, making the bike more stable, but less agile and responsive whilst manoeuvring.

26in Wheels

26 inch wheels were once the go-to wheel size on adult mountain bikes. However, they are now typically only found on the smallest frame sizes, and on junior bikes. 26 inch wheels are lightweight and give the bike very agile handling. The downsides to 26 inch wheels are their poor rolling resistance on rough ground, and the reduced contact patch due to the smaller wheel circumference.


Suspension components

Mountain bike suspension components (i.e. the fork or rear shock absorber) are also a way to identify the quality of a bike. While Fox and RockShox are the most common manufacturers, there are a number of brands producing suspension components for mountain bikes.

Entry level full suspension mountain bikes (up to approximately £1300) may come supplied with a fork & rear shock supplied by SR Suntour, X-Fusion or RockShox. These components will allow a limited amount of adjustment, including:

  • Coil spring preload / air spring pressure adjustment
  • Lockout switch
  • Rebound damping adjustment on models towards the top of the price range.

Mid-range & enthusiast bikes (up to approximately £3500) use components from brands including Fox, RockShox and Manitou. At this level, suspension components have features like:

  • Preload adjustment / air spring pressure adjustment
  • Rebound damping adjustment
  • Lockout switch
  • Multi-position ‘mode’ switch
  • Components towards the top end of the enthusiast price range may also feature compression damping adjustment as well.

Top of the range & competition spec bikes (over £3500) also use components from Fox, RockShox & Manitou, with a few select models using parts from Ohlins. At this price, suspension components have features including:

  • Coil spring preload adjustment / air spring pressure adjustment
  • High & low speed rebound damping adjustment
  • High & low speed compression damping adjustment
  • Lockout switch
  • Multi-position 'mode' switch
  • Advanced low-friction coatings (e.g. Fox’s golden-coloured Kashima coating)
