B-17 Tech Installation

Hydraulic Fork Installation Instructions


1) All quality forks are available as either external or Internal brake Line configuration. On conventional forks the caliper is external and on some inverted forks the caliper is an integral part of the lower leg. Assembly is similar for all models, but on Internal Brake line models you must be careful not to twist the lower leg relative to the line, as this will cause the line to become twisted internally.


2) Avoid twisting the inner tube relative to the outer tube prior to installing forkson Internal Line Models.

3) Apply a thin coating of Anti-Seize to the body cap threads and to the triple clamp threads.

4) Test fit the body cap into the triple clamp to be sure that threads are clean and clear and to familiarize yourself with the thread fit.

5) Inspect the surface of the holes in the lower tree that the fork tube passes through. If there are burrs or chromebuild up there, you will want to lightly sand (400 grit) the burrs to prevent the tubes from being scratched as they pass through the lower triple clamp.

6) Cover the outer tube (masking tape, packing tape, sturdy paper or plastic barrier held by tape at the ends.) to prevent tubes being scratched by the lower tree. Scratches during assembly are not covered by warranty.

7) Steering Stop. Install steering stop pins into trees. Your steering neck should include a tang to engage the steering stop pins inside the smiley face cut outs. If your frame does not have a tang you must either attach one to the frame or use press in steering cups that have a tang. You may also purchase a special lower bearing race that already has a steering stop tang attached to it. Some trees use allen bolts as stop pins. These allens may be adjusted to give you the exact clearance you need. If you are using an alternative steering stop you may attach it to the threaded holes provided on the lower tree.


8) Install the trees; do not insert bolts into lower triple clamp. Do not tighten steering stem.

9) Use the 7/16 bolt and washer to slightly pry open the tube holes in the lower triple clamp. Do not over open the hole as this may cause the chrome to pop. This is not be warranted by the manufacturer.

10) Re-Apply a thin coating of Anti-Seize to the body cap threads and the triple clamp threads.

11) On Phantom line legs route brake line through tree.


13) Insert the legs into the trees. (on Internal brake line models the line routes through the passage in the trees.


15) Tighten triple clamp bolts.

16) After the legs have been installed, adjust the steering stem bearing and install the steering stem lock screw. The lock screw is tightened against the stem to restrict its motion. Steering stem bearings should be adjusted so that the triple clamps turn as free as possible, but without the bearing “clicking”.

17) Install wheel, note that the integral caliper has a very wide opening. It is not necessary that the brake rotor is centered in the caliper. It is more important to center the wheel in the forks. If the axle has difficulty passing through the axle clamp, you can use the 7/16 bolt to pry open the axle clamp hole in a similar fashion to the lower tree hole.

18) After the bike has been assembled, loosen the triple clampcolts and loosen the axle. Bounce the bike on the front suspension several times. Then retighten all the bolts.

19) The Internal brake line uses any standard –2 brake fitting. Select the one that works for your application.

20) After the brakes are bled and the headlight installed use the optional hidden covers (if ordered) to cover the steering stem, headlight bolt and axle. The Hidden Hardware kit may be ordered separately and includes Covers for the Steering stem and Headlight bolt, as well as a cover for the axle.

On older trees, pins are used for the steering stops. However all modern Solid ride and Velocity suspension forks use a socket head cap screw for steering stop adjustment.

Tree Instructions for Installing Tubes

Important Instructions. Opening in lower tree must be opened with a 7/16-NF bolt and a small washer (used as a stop) to allow tube to pass thru easily. You must use packing tape or paper to protect the tube sliding through the tree. Inspect holes in lower tree for burrs and use fine sandpaper to remove any internal burrs before assembly. Chrome on Chrome is guaranteed to scratch. Not following this procedure will result in damage to tubes – not covered by warranty.

Washer acts as a stop and protects the threads. This exclusive American Suspension feature is patent pending. Be sure to put Anti-Seize thread lubricant on the threads of the fork cap before screwing them into the triple clamp. Steering stop pin contacts tang on frame to act as a steering stop. Pins go in front or back holes depending on your neck design.
