CHAPTER 1: FORK / STEM / HANDLEBAR INSTALLATION
1.1 INSTALLING THE FORK INTO THE STEERER TUBE
Specialized Shiv frames are designed in conjunction with the Specialized aero stem/handlebar combo or a 1 1/8” x 31.8mm standard stem with the
Specialized alloy aero handlebar. The Specialized aero handlebars work specifically with the handlebar risers and extensions to offer the greatest
range of position adjustment.
When using a Specialized aero stem or a Specialized Multi-Position 1 1/8 x 31.8mm stem, Specialized strongly recommends following the specific
instructions below to guarantee the best build possible.
TECH TIP:
Before starting the assembly of the bike, install the seatpost in the frame as shown in Chapter 5.
WARNING! When placing the bicycle in a repair stand, clamp the seatpost using a frame clamp specifically designed for thin-wall carbon tubes
(for example, the Park Tools 100-X4 Extreme Range Clamp). Clamping the seatpost with a standard clamp can cause damage to the seatpost
that may or may not be visible. Do not clamp the frame tubes.
TECH TIP:
For the initial setup, since the proper height is not yet determined, it is recommended to cut the steerer tube at the highest
position for assembly (2 x 25mm steerer tube spacers), then cut the fork to the desired height once the build is complete and the bike
has been fit to the rider.
1. Install the lower 1 1/8” cartridge bearing
A
on the steerer tube of the fork.
2. Install the fork
B
into the head tube
C
of the Shiv frame and settle the bearing into the base of the head tube.
3. Install the upper 1 1/8” cartridge bearing
D
on the steerer tube of the fork and settle the bearing into the top of the head tube.
4. Install the bearing compression ring
E
over the bearing.
5. Install the top cap
F
over the compression ring.
6. Install 2 x 25mm head tube spacers
G
onto the steerer tube.
7. Install the stem
H
that will be used to build the bike onto the steerer tube. This is important to make sure the steerer tube is cut to the correct length.
8. Mark the steerer tube directly above the stem, then remove the fork from the steerer tube. Make a 2nd mark 2mm below the original mark.
9. Place a steerer tube cutting guide tool on the steerer tube, with the guide slot aligned with the 2nd mark. Double-check the measurement, so that
the mark is 2mm below the top of the stem with 2x25mm spacers installed below the stem.
10. Cut the steerer tube (using a carbon cutting blade, or a blade with a minimum 36 teeth) at the cut mark, remove the tool, then remove any burrs from
the top of the steerer using a fine grit sandpaper.
11. Repeat steps 1 through 7.
