Nylon composite bronze series sole

The Bontrager Circuit employs a nylon composite Bronze series sole. This material is composed of 85% nylon and 15% fiberglass. Power is delivered through the bike via these soles.

Moreover, the sole’s PowerTruss construction is engineered to be adequately stiff without adding unnecessary weight. They have a rating of 7 out of 14 in the brand’s stiffness index chart, which means they perform well while also yielding enough flex.

Excellent ventilation

Window pockets are placed in the outsole to provide excellent airflow throughout the foot.

Universal cleat systems

This footwear is compatible with both three-bolt and two-bolt cleat systems. Shoes that accommodate both systems are more commonly known to have universal cleat systems. Take note that the two-bolt mountain plate is sold separately.

If you choose to use the three-bolt system, these are the pedals you can try Shimano 5800 SPD-SL, Time XPro 10, and Look Keo 2 Max. For two-bolt pedals, check out the following: Shimano XT M8000 XC Race, Nukeproof Horizon CS CrMo Trail, and Crank Brothers Mallet E.

BOA L6 dial

The Bontrager Circuit employs a BOA L6 dial to govern the midfoot and top-most area of the foot. The dial can be tightened in increments and can be completely loosened in an instant. The forefoot area is secured by a single Velcro strap. Both can be adjusted while on the go.

The upper is crafted from 56.9% PU, 10.5% Polyester, 32.2% Nylon, and 0.4% Steel. While the inner lining is made of 100% Polyester. This yields a supple yet supportive fit.
