Common Questions

How does the Alloy Stumpjumper compare to the carbon version?

Geometry and suspension performance are very similar; the alloy frame simply weighs more, making the carbon version the choice for weight-focused riders willing to pay significantly more.

Is the Stumpjumper good for both climbing and descending?

Yes — Specialized specifically engineered the geometry to balance both, which is a big part of the model's long-standing reputation.

What size wheels does the Stumpjumper use?

29-inch wheels on most frame sizes, though smaller frame sizes may use a mixed wheel setup — check current size-specific specs before buying.
