Terms & Conditions
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
Please Note: This bike is not eligible for shipping and can only be purchased at one of our retail locations
Shimano Di2 SM-JC41 Junction B Box
This Di2 B- junction box "splits" the main wire from the A junction box. It is a simple, small hub that has 4 female connectors and serves as the junction point in the bottom bracket area. Usually a front derailleur, rear derailleur and battery are connected to the Junction B. Please note that this junction box is specifically made for frames that accomodate an internally routed system. Shimano recommends the SM-JC40 for externally-routed frames.
