MEASURING YOUR CURRENT SETUP
Before you start installation, take a full set of measurements of your existing bar setup for later
reference and UCI compliance.
Key measurements to take are:
Length from centre of bottom bracket to bar
tip end (including the shifters).
Height difference from top of elbow cup
(measured at the fore/aft centre) to top tip
of shifter/bar end.
1. Height of top of elbow pad from the
ground (measured at fore/aft centre).
2. Top of shifter tip from the ground.
SECTION A - MEASURING

5
www.fastTT.bike
FastTT Aero Bar Installation Guide – TT Bar
Distance between outside edges of elbow
pads. Note the distance where you
measured relative to the bottom bracket so
you can repeat the same measurement for
your FastTT bars.
Width between shifter tips or bar ends.
Once measured, remove your old extension bar and shifters, but leave the brackets mounted
to the base bars (if applicable). Disconnect shifter cables.
Elbow pad measurements for UCI
compliance should be taken at the fore/aft
centre of the pad.
Please refer to the UCI website for measurement rules based on rider height:

SETTING UP FOR UCI RULES
For UCI legal setup you need to measure the distance from the centre of the bottom bracket to
the tip of the bars or finger hook. You will also need to measure the height from the centre of
the elbow pad to the top of the bars or finger hooks. If you don't have access to a measuring jig
you can use a vertical wall as suggested in the diagram below, but ensure the wall is exactly 90°
vertical (check with a spirit level).

TRIMMING THE BAR ENDS (AS REQUIRED)
Hold the bar end as you would when riding, resting the
bottom of your hand on the top surface of the
extension.
It should be a snug fit with NO GAPS between the
base of your arm/hand and the bar extension.
Measure how much bar end you require to fit your
shifter, taking into account the extra length the
shifter adds to the bar.
Mark the top of the bar ‘A’ including shifter body
length. Deduct the length of the shifter from ‘A’ and
mark position ‘B’. The difference between ‘A’ and ‘B’
should equal the length of the shifter (excluding the
insertable section).
Trimming the bar ends to the correct length is essential for accurately measuring the UCI
dimensions and should be completed before moving to the next step. When measuring, the
shifter buttons must be inserted and included in the measurements for UCI compliance.
Measure twice, cut once! Use a hacksaw or Dremel cutting tool to trim off the unwanted bar.

Placement options
FastTT aero bars offer a wide range of bolt holes
and bracket placement options for you to find your
preferred setup.
Fitting adjustable angled risers
If fitting FastTT adjustable angled risers, bolt the
bottom blocks of the risers to your base bar or
spacer stack. Tighten to maximum 6Nm.
Add the top block to the bottom block and
insert the M6 locking bolt. Adjust to your
preferred angle and tighten the bolt to a
maximum torque of 12-13Nm.
Insert two 10mm bolts into the
slots in the top side of the
mounting bracket. Only button
head bolts can be used. If you
replace them with hex cap screws
the bracket WILL NOT sit flush
with the bar base.
NOTE: The 4x 16mm bolts should NOT be used for mounting the TT bars. These are only used
for FastTT Tri bars.
SECTION C – MOUNTING THE BARS

FastTT Aero Bar Installation Guide – TT Bar
Fitting the mounting brackets to FastTT angled riser and Profile Design brackets
Using the supplied M5 button head bolts, attach the bracket to the top block of the FastTT
Adjustable angled riser or to the Profile Design wing bracket, depending on the mounting
option you selected. At this stage only tighten the bolts enough to be able to move them with
a little effort. This will make the inwards/outwards angle adjustment easier. NOTE: You MUST
fully tighten to bolts after adjusting the bars.
Fitting to all other bikes with the Universal bracket
If you selected the Universal mounting option, you need to drill bolt holes in the bracket
matching the bolt pattern of your mounting element (NOTE: DRILLING IS ONLY REQUIRED FOR
THE UNIVERSAL BRACKET). The Universal bracket has a measurement grid on the underside to
assist you.
SECTION C – MOUNTING THE BARS

10
www.fastTT.bike
FastTT Aero Bar Installation Guide – TT Bar
UNIVERSAL OPTION ONLY: Select the appropriate size
drill bit based on the diameter of the mounting bolts
you are using. Installation is easier if you drill the holes
0.5mm wider than the bolt threads. Once drilled, bolt
the bracket to your mounting pad or stack.
Inwards/outwards angle will be determined by where
you drill the holes. If you want to make small
adjustments to the angle you can modify the holes
slightly with a file or Dremel.
Unless you ordered FastTT long bolts you will need to provide the correct length and thread
diameter bolts for your bike. Tighten the bolts to the torque specified by the bolt supplier or
your owner’s manual.
Bolt the bracket to the base of the bar in your
preferred position. You can easily make changes by
removing the bracket and repositioning it. There
are 4 holes in the bracket. A MINIMUM of 3 bolts
should be used on each side for safety and strength
(4 bolts are recommended).
Adjusting inwards/outwards bar angle
With the bars bolted to the bracket, you can adjust the inwards/outwards angle to suit. There
is up to 40° of adjustment available. Once adjusted to the correct position, remove the bars
and tighten the 2 bolts that fix the mounting bracket to the angled riser, Profile Design bracket
or your mounting pad to a maximum of 6Nm.
SECTION C – MOUNTING THE BARS

www.fastTT.bike
FastTT Aero Bar Installation Guide – TT Bar
If you are using spacers, you may need to purchase stainless steel or zinc coated cap screws of
an appropriate length and thread diameter (M5 or M6) to suit your setup. Most cap screws are
available from a nut and bolt supplier. We also stock a comprehensive range of long mounting
bolts: https://www.fasttt.bike/product-category/mounting-bolts/
If you are using the FastTT adjustable angled riser,
or our spacers, they have a channel in the rear to
fit the shifter wires.
Refit the bars to the bike and tighten the bolts to a maximum torque of 6Nm. A MINIMUM of 3
bolts should be used on each side for safety and strength (4 bolts are recommended).

INSERTING ELECTRONIC SHIFTER CABLES AND INSTALLING THE SHIFTERS
The shifter cable must be drawn through the internal bar cavity and out the pre-drilled exit
hole. A shifter draw wire has been supplied for this purpose.
Remove the rubber grommet and insert the black end plug of the draw wire into the hole and
feed it through the bar until it exits out the end of the bar tube. If necessary, use the curve of
the cable to assist in guiding the draw wire into the bar tube.

Plug the shifter cable into the black tip of the draw wire as shown below and carefully pull it
through the bar so that it appears at the rear exit hole. Pull it clear of the rear exit hole and
unplug the shifter cable from the draw wire.
• Di2 - firmly insert the black tip of the draw wire into the Di2 plug connector
• SRAM – firmly insert the silver SRAM cable plug into the black tip of the draw wire
For older Di2 shifters where the cable inserts from outside the bar tube, the draw wire is fed
from the opposite direction i.e. feed it into the hole at the base of the bar end tube and out
the rear hole.

Route the shifter cable to the derailleur according to the most efficient route. Try to keep the
cable as close to the frame as possible for maximum aero efficiency.
Insert the shifters and tighten according to the manufacturer’s instructions.

IMPORTANT SERVICE NOTE!
After a few rides we recommend that you check and retighten the mounting bolts on your FastTT
Aero Bars. The bolts can become slightly loose after initial riding due to natural bedding in of the
bolts into the carbon mounting base. This can potentially cause a small amount of lateral movement
in the bar. If this occurs, please retighten to a maximum of 6nm. We also recommend applying a very
small amount of thread lock to the bolts before refitting them. If at any stage you notice lateral
movement of the bar you should retighten the bolts.
