The Nevegal DTC is a good choice for your 29er for both front and rear or just the front tire. The tread is aggressive and confidence inspiring, but also rolls quick. That is what makes this tire special - most aggressive tires that grip well tend to be sluggish and somewhat slow, the Nevegal rolls extremely well and it's cornering prowess is unmatched for tires in it's class. It also works in a variety of terrains form hard pack, loose rocks and talus, roots and mud.
The Kenda DTC- Dual Tread Compound offers two specific compounds. The center tread is firm for durability, longevity and fast rolling, while the softer outer tread improves trail adhesion and resiliency. Open pattern shed mud and debris and is an excellent choice for 29er style riding.
