We strive to get you the gear you want at a competitive price. If you find an item we offer from a competitor at a lower price, let us know. We will do our best to instantly match their price. To qualify for the Price Match, your purchase must meet the following conditions:
Price Matches may only be honored on identical items. The product must be the same make and model (i.e., the same size, color, year, etc.).
The identical items must be in stock and ready for immediate delivery at the competing dealer.
Price Matching voids any currently advertised Jenson USA promotions or special offers (i.e. free shipping, free headset...). If the competitor offers free shipping on the specific item, Jenson USA will still match the price and free shipping offer.
The product must be brand new. We do not Price Match refurbished or used items.
Our Price Match Policy is valid only for qualified Internet retailers.
The competing dealer must be an authorized US retailer for the brand. This means that the manufacturer lists this dealer as an authorized and official retail web site.
The competing online retailer's principle business must be located within the United States.
Our Price Match Policy does not combine with any competitor’s coupons, rebates, promotional offers, or product-combo deals on your order.
Some items may not be eligible for price match due to manufacturer pricing requirements.
The Price Match Policy is subject to change at any time.
If you have any questions regarding a Price Match, one of our Gear Advisors will be happy to lend you expert guidance via phone, email, or chat.
Price Matches made post-purchase will be refunded via gift card
Making power is easy. Making power with the right feel, that was Hayes’ challenge. They did this by creating an all new system. The Dominion master cylinder is factory tuned for the shortest dead stroke possible and a crisp bite point. The Dominion A2 caliper utilizes two pistons in the most structurally rigid design possible. It features a cold-forged caliper and KingPin structural pad retention bolt that increases stiffness. With a motorsports inspired Two-Stroke dual port bleed system, industry leading DOT 5.1 fluid and Kevlar hose, the hydraulic system is engineered for ultimate performance across all temperatures and easy maintenance. Dominion A2 features the proprietary QuickBite² system for fast and consistent burnish, coupled with Hayes’ D-Series rotor to manage the heat with less braking noise. If you're on the hunt for a terrific 2-piston brake then the Dominion A2 should be at the top of your list.
