Specialized Stumpjumper Comp Alloy vs Trek Fuel EX
The Stumpjumper Comp Alloy is the better value for most trail riders: $2,599.99 at Gannett Peak Sports as of November 4, 2026, versus $4,488.88 at eBay for the Fuel EX. The Fuel EX gives you more travel (145 mm rear, 150 mm fork), 2.6 in tires and a lighter carbon build, but that listing is the 9.8 XT Di2 build, so you pay roughly $1,900 more. Pick the Specialized if budget and alloy durability matter; pick the Trek if you want a longer-travel, lighter trail bike and will pay for it.
Today the Specialized Stumpjumper Comp Alloy costs $3,599.01 less at its best price.

What reviewers say
Specialized Stumpjumper Comp Alloy
Buyers rate it 4 out of 5 and describe it as versatile, durable and good value, with smooth tracking over rough ground. The main complaint is color: at least one buyer received dark grey/black instead of the gunmetal satin/taupe shown.
- Versatile and durable for the price
- Flows smoothly over rough terrain
- Fast rolling and stable through rough sections
- Improved rear rigidity and straight tracking
- Wrong frame color shipped on at least one order
- Color mismatch described as false advertising
Trek Fuel EX
Reviewers call the Fuel EX a strong trail bike and a big generational leap over older versions, capable on long-distance trail rides. At least one owner reports creaking from the rear pivots.
Questions and answers
- Which is better for a beginner trail rider?
- The Stumpjumper Comp Alloy. It costs less, the alloy frame tolerates crashes, and 130/140 mm travel is plenty for most trails. The Fuel EX is the stronger pick once you ride harder and want more travel.
- Is the Fuel EX worth the extra money?
- If you want a lighter carbon frame, 145/150 mm travel and 2.6 in tires, yes. If you mostly ride moderate trails, the Stumpjumper does the same job for about $1,900 less.
- Which has more suspension travel?
- The Fuel EX, with 145 mm rear and a 150 mm fork. The Stumpjumper Comp Alloy has 130 mm rear and a 140 mm fork.
- Which is lighter?
- The Fuel EX. Trek lists 32.1 lb in size L for the 9.8 XT Di2 build. Specialized does not publish a weight for the alloy Stumpjumper, and alloy frames generally run heavier.
- Can I run mixed wheel sizes on either bike?
- The Fuel EX supports a 29 in or MX setup with additional hardware. The Stumpjumper Comp Alloy is listed as 29 in only.
- Which lasts longer?
- Both frames are durable, but the alloy Stumpjumper is cheaper to repair or replace after a hard crash. Watch the Fuel EX rear pivots, which one owner reports creaking.
