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 long-awaited Shimano XT 11 speed drivetrain has made its grand entrance! Featuring Shimano's innovative Shadow Plus technology and a refined geometry, the Deore XT M8000 11-speed rear derailleur is designed to reign authority over today's aggressive style of trail and all-mountain riding. By maintaining chain tension, the optimized slant angled Shadow system eliminates chain slap and greatly lowers the chances of dropping your chain. The easy-to-adjust chain stabilizer makes it quick and effortless to dial in the perfect amount of stability for varying conditions and terrain.
The XT M8000 rear derailleur employs a new hyper low-friction coating technology and an improved pulley design that greatly lightens up the shift operation, allowing up to 20% less effort. Finally, support for larger rear clusters is offered as well, with clearance on up to 11-46T rear cassettes for massive range.
Don't know which cage length to choose? Choose a long cage "SGS" derailleur if you have 3 chainrings on your crankset, and a medium cage "GS" if you have 1 or 2 front chainrings.
