WTB Nine Line 2.25 29" Tire


Product Overview

The Nine Line is the new-school approach to a top notch, 29-inch specific, lightweight race tire. Its micro-square knob tread design and supple casing provide impressive traction and control. We brought these in for the bikepacking enthusiast who also wants a fast rolling, lightweight and tubeless compatible tire. Can also be used with tubes.

"Dual DNA" rubber compound; Dual DNA is the perfect mix of efficiency, traction and durability. The centerline tread features a firmer rubber compound that boasts faster rolling and increased durability, while the side knobs are composed of softer, slower-rebounding rubber that improves control and grip.

Many riders convert non-tubeless ready tires and/or rims to tubeless which Bike Touring News does not recommend. There are specific design considerations for tubeless systems and WTB is addressing those. From the WTB website:

"Our TCS™ (Tubeless Compatible System) technology is the solution for riders seeking high performance, lightweight and durable mountain bike wheel systems that are easy to install, fun to ride and simple to service. TCS tires are the first sealant tubeless tires to receive Mavic UST® certification, which means a proven fit between sealant tubeless tire and rim. Say goodbye to air compressors, tire levers and pinch flats. Say hello to your full riding potential."
