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
The Giro Helios Spherical helmet is Giro’s high-performance adventure-ready helmet featuring their Spherical protection technology, perfect for your next backroads exploration session or competitive group ride. The Spherical ball-and-socket technology incorporated into the Helios provides protection from rotational forces during an impact, allowing the inner and outer layers to rotate separately to disperse harmful forces in the event of a crash. Progressive Layering allows for better absorption of energy from low and high speed impacts. The 15 vents on the Helios direct air into internal channels, providing excellent cooling during hard efforts, while Coolfit antimicrobial padding keeps the funk at bay. No matter the terrain, the Helios Spherical by Giro will take you there.
