Specialized Stumpjumper Expert Carbon 29 Review

[SV_VIMEO id=”59379854″] Can a 29er out-perform a 26er when it comes to technical trail/all-mountain riding? Specialized certainly think so; they’ve been espousing the virtues of a bigger wheel for many years and have been incredibly active in pushing 29ers into longer travel applications. In fact, Specialized are so convinced the big wheel is the right …

  • Remarkably versatile in all kinds of situations. Efficient and hassle-free suspension. Great handling and grip. No corners cut in spec or finish.

  • 'Dangler' chain guide not needed with Type 2 derailleur. Jagwire cable housing is mushy when shifting.

Sometime between the death of the aluminum hardtail and the popularization of full suspension, we strayed down the platitudinous path of categorization: XC race, trail, all-mountain, gravity, or DH.... While these names may help guide an uninitiated buyer to the right machine, it's the new wave of bikes designed to transcend categorization that arouses wide-eyed enthusiasm from the true aficionado of singletrack.
