Vintage Cannondale Delta V 2000 mountain bike with front suspension, orange handlebars, and detailed specifications listed on the side.

Thank you for purchasing the Delta V Core by Jereko Gear. Please follow the instructions below for installation.

Please be aware that the Delta V Core is compatible exclusively with the Type I Delta V suspension fork, featured on 1992 Cannondale Delta V mountain bike models. If you're uncertain which suspension fork your bike has, simply click the button below to confirm your fork’s generation.

Installation:

  • There's no need to remove the fork for installation—simply loosen the stem to proceed.

  • Remove the valve cap, dampening dial, and large aluminum nut from the top of the fork.

  • Release all air pressure from the fork by compressing the Schrader valve core.

  • Using a pin-spanner, such as the Park Tool SPA-2, remove the top cap from the steerer tube. If this proves difficult, place the fork in a vice, allowing you to maintain pressure on the spanner while it is unthreaded.

  • Compress the fork to allow easier access to the brass nut and nylon spacer inside the steerer tube. Keep the fork compressed for the following steps.

  • Remove the brass nut and nylon spacer.

  • Clean the interior threads of the steerer tube and the nylon spacer.

  • Next, ensure that the Delta V Core is correctly oriented. Each end of the Core features two holes—a large one and a smaller one. The smaller hole should always face downward, indicating the bottom of the Core.

  • Insert the nylon spacer.

  • Slide the Core over the center rod, bottom first, and push the Core down until 1/4 inch of threading is visible at the top.

  • Start by threading the brass nut onto the center rod. You may notice that the brass nut does not easily thread into the larger hole at the top of the Core—this is normal. Just continue turning the Core to engage the threads until the nut stops. If you need to remove the nut, the Core is flexible enough to let you pinch the nut gently and unthread it for removal.

  • Uncompress the fork.

  • Lightly apply grease to the steerer tube threads and reinstall the top cap.

  • Finish by first reinstalling the aluminum nut to the Schrader valve, followed by the dampening dial, and finally the valve cap.

  • NOW GET OUT THERE AND RIDE!
