Donnelly Tires: PDX Tubular Bike Tire
The PDX Tubular Cyclocross Tire
The cutting-edge cyclocross tire that mixes the incredibly popular PDX tire tread with an innovative tubeless casing to create the best tubular cyclocross tire.
Bike Radar rigorously reviewed the Donnelly PDX and gave it a score of 4 1/2 stars out of 5 stars, saying "The Donnelly PDX is up there with the best tubular mud tires for cyclocross in terms of performance, plus it's very durable and ready to mount right out of the box."
The PDX is named after the epic cyclocross courses of Portland, Oregon, where frequent rain and a cyclocross-crazed culture intertwine to bring forth the muddiest and most extreme races. This tire preforms extremely well all around and is particularly suited for playing in the mud.
The center knobs in the tire are aligned to give your bike a fast roll on hard pack and pavement, no matter what the weather conditions. Aggressive side knobs offer superior cornering, and the leading edge of the knob gives you extra traction for acceleration.
Bike Tire Size: 700 x 33mm 378 g
Bike Tire Tread: Aggressive knobs with wide spacing for mud clearing. Center knobs in a line for fast and easy rolling. Soft rubber material for extreme grip and shock absorption.
Tubeless: There is no inner tube, instead the entire casing is airtight. This creates a very light-weight tire, but more importantly it is very resistant to punctures. The tire accepts sealant liquid easily, and typical punctures can be quickly sealed from the inside.
Durable: The sidewall is much more durable than traditional tubular tires, and is coated with rubber to prevent deterioration from water, mud, and dirt. No additional sidewall coating is necessary. The tread is manufactured integral with the bike tire and can't peel away or become detached from the casing.
High-quality: Every bike tire is produced in a highly exacting process that creates a very straight tire with no variances in size or alignment.
Ease of Use: The high-quality manufacturing process results in a tubular tire that is much easier to install than other brands. The bike tire is straight and the base-tape is consistent, providing an easy to glue surface that won't peel away from the casing or become damaged from normal use.
Removable Valve Core: Simple unthread the valve core and use a squeeze bottle or syringe to add liquid sealant to the tire to repair most punctures or prevent future punctures.
