Specification summary: Fox 34 Rhythm 130mm / Fox Float DPS Performance 130mm suspension, 29-inch wheels, SRAM SX Eagle 12-Speed, SRAM Level 2-Piston brakes, weight 15.6 kg, price £2,464. At £2,464 it is about 53 percent below the typical bike price in the database, and at 15.6 kg it is about 5 percent above the typical bike weight in the database. Short-travel trail bikes trade outright descending ability for lively handling and efficient climbing, and are most at home on flowing singletrack.
Aluminium frames are durable and more affordable, with a small weight penalty compared with carbon. The 29-inch wheels roll over obstacles efficiently and carry momentum on rough ground. The mechanical 12-speed drivetrain offers simple, serviceable shifting with a wide gear range. Two-piston brakes save weight and suit lighter, cross-country-oriented riding.
Verdict: Specialized Stumpjumper Comp Alloy scores solidly in this database with a 4.5 rating. It suits new trail riders. Main caveat: basic components.
How We Rate
How we rate
Every rating on Gear Matrix is published alongside the information it is based on, so you can judge the score for yourself rather than take it on trust.
Gear Matrix ratings are editorial assessments built from published manufacturer specifications and comparative specification data. They are not presented as the result of physical product testing. Where an article is based on a first look, a launch announcement or a press release, the article says so.
Weight-to-power on e-MTBs
Where a weight-to-power ratio is shown it is calculated from two manufacturer-declared figures: the bike’s weight in kilograms and the motor’s declared output. Both inputs are required before any ratio is displayed. We never estimate a missing value, and we never infer a figure from a different model in the range.
The full breakdown of rating criteria is being prepared and will be published on this page.
