Giro Chamber TR MTB Shoe Description The Chamber Trail builds on the DH-proven power transfer of the Chamber, while reimagining a performance-driven upper that maximizes breathability, enhances pedal-feel, and saves weight. Details Built on the same tri-molded DH platform as the World Cup-winning Chamber, the all-new Chamber Trail is engineered to deliver a lighter feel and enhanced ventilation, without sacrificing any power transfer. A BOA Fit System powered by single Li2 machined aluminum dial mates with durable, injection molded lace guides, a closed-knit ankle cuff to keep out debris, and a microfiber upper with integrated mesh ventilation. With Giro&';s proprietary Sensor rubber that balances grip and durability plus an optimized +10mm cleat setback, the Chamber Trail is the next step in progressive MTB riding.
