What are the features that make it awesome?
SERIES – PRO
Everyday Luxury – Our workhorse handmade tire is the PRO series, delivering performance and ride feel unmatched by traditional vulcanized tires. Perfect for the rigors of daily riding.
CASING – Super Polyester 260TPI
Super Polyesters with higher thread counts of 220-300tpi make up our most affordable handmade casings. Polyester is much softer and stronger then nylon, is impervious to water and quite durable.
CASING PROTECTION – Silver
Silver Armor is an internal sidewall reinforcement that improves resistance to cuts and punctures that can occur on bad pavement or rough roads.
TREAD COMPOUND – SMARTplus
A tougher and more cut-resistant rubber compound for the demands of gravel and rough terrain. SMARTplus wears longer to keep tread edges sharper, improving confidence over mixed surfaces.
PUNCTURE PROTECTION – PPS2
Our tires designed for use on rough roads, cobbles and gravel are built with an additional layer of PPS (PPS2) on the inside of the casing.
