Currency Exchange Rates close

Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.

Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.

Dirt or pavement, a conundrum as old as the tale of time. Diamondback has created a bike that will conquer both dirt and pavement. The Insight STI-8 is an all around cycling machine. Take it to the dirt, and the strong 6061 T6 aluminum frame will hold up to the riggors of the fire roads. Ride to the coffee shop and back without feeling like you are pushing an ox. Twist shifters help you find the optimal gear for whatever terrain you may come across.
