Strengths of the Specialized Stumpjumper 15 Comp

GENIE Technology – Revolutionary Suspension

The Stumpjumper 15 is the first trail bike equipped with GENIE, a patented air spring that combines the sensitivity and control of a coil spring with the progression and lightness of an air spring.

  • 39% less bottom out compared to traditional air springs

  • 57% more traction compared to standard shocks

  • 16.3% better impact force management

Extreme Control, Coil Feel, Air Progression

GENIE uses a two-stage compression curve: linear in the initial part and progressive in the last 30% of the travel, offering superior control on technical trails and great comfort even on the hardest impacts.

A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.


Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.


How to use size charts

We've created a simple guide to help you find the right bike size:

  1. Check out our size charts for each bike type.
  2. Learn more with specific tips to help you make the right choice.

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

Cut Recommended height Horizontal tube length
XS Up to 157 cm 48-50 cm
S 157-167 cm 50-53 cm
M 168-178 cm 53-56 cm
THE 178-185 cm 56-58 cm
XL Over 185cm 58-62 cm

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Cut Recommended height Size (in inches)
XS Up to 157 cm 14"-16"
S 157-167 cm 15"-17"
M 168-178 cm 16"-19"
THE 178-185 cm 18"-20"
XL Over 185cm 20"-23"

Sizes also vary depending on the type of MTB: full-suspension , hardtail or fat bike .

Children's bikes

The size depends on the size of the wheels, often associated with age:

Age Wheel Size
1-3 years 12"
2-4 years 14"
4-6 years 16"
5-8 years 20"
8-10 years 24"
Over 10 years 26"/27.5"

What to do with half measures?

If you are between two sizes:

  • Comfort : Choose the larger size.
  • Performance : Go for the smaller size.

Final tips for choosing

  1. Consult the manufacturer's instructions : Always check the brand's guidelines.
  2. Ask an expert : a specialized workshop can help you choose based on your height, ideal reach and goals.
  3. Test the bike : If possible, test the model you intend to purchase.
