Page 9: Handlebar Assembly Steps
5.1. HANDLEBAR ASSEMBLY STEPS !IMPORTANT! First assemble the 4ZA Cirrus TT kit without cable routing to determine the desired positions. After determining the desired position disassemble and reassemble the 4ZA TT kit with cable routing. Consult page 17 to 20 to make sure the cable routing is done appropriately. 5.1.1. -
Page 10: Armrest Installation Steps
5.1.1. ARMREST INSTALLATION STEPS The second step in the 4ZA TT handlebar kit installation is the installation of the armrests. Page 17 provides the necessary information concerning the adjustability of the armrests and the necessary components to achieve the desired setup. Pay attention to all warnings given on page 17. Assembly of the TT kit is considerably easier with two persons. -
Page 11: Extension Settings
5.2. EXTENSION SETTINGS The position of the extensions can be altered in width, height, angle and length. Mount the extensions so the handholds are located in the desired position. Armrest pads can subsequently be moved relative to the extensions allowing to optimize pressure points and position. 5.2.1. -
Page 12: Extension Height
5.2.2. EXTENSION HEIGHT Height of the extensions can be determined by inserting the appropriate combination of spacers. Start the stack using a basebar spacer, end the stack using an extension spacer. Stacks higher than 20 mm can be achieved by using the riser set, extra information on this set can be found in the topic expansion sets. !IMPORTANT! In case of a stack of spacers higher than 20 mm it is obliged to add a bridge for added stability. - Page 13 10 mm 5 mm 3 mm 3 mm 5 mm 10 mm 4za cirrus tt handlebar | manual |...

Page 14: Extension Angle
5.2.3 EXTENSION ANGLE The extensions can be mounted at an angle of 0 or +5 degrees. Depending on the angle different extension spacers and extension insert spacers have to be used. The 4ZA TT kit contains two different types of extension spacers and extension insert spacers. The 5° extension spacer is noticeably thicker than the 0° extension spacer, as shown on the image below. - Page 15 Thread a wheel quick release in the bottom of the extension insert spacer to make positioning of the insert inside the extension easier. Remove the wheel quick release after finishing installation of the extension insert spacer (as indicated in RED on the image below). Wheel quick release !IMPORTANT! When mounting the extensions at an angle of 5°...

Page 16: Extension Length
5.2.4. EXTENSION LENGTH The extensions are provided with a series of holes that cover a 135 mm range of mounting positions with a step size of 15mm. Note that the arm pad fixation position is not related to the extension fixation position. !IMPORTANT! To prevent the extensions from hitting body or bike parts we advise to cut them to size when mounted in the shortest position (left image below). -

5.3. ARMREST SETTINGS The position of the arm rests can be altered in height, length, width and angle. 5.3.1. ARMREST HEIGHT AND LENGTH Similar to changing the extension height, the arm pad height can be altered using the appropriate selection of spacers. 5.3.2. -
Page 18: Cable Routing Brake Controls
5.4. CABLE ROUTING BRAKE CONTROLS The 4ZA aero basebar features an internal cable routing system. Depending on the brake setup on your bike you will run the cable full internal (RED) or semi internal (GREEN) as shown in the schematic representation on page 16. Dotted parts of the cable are run internal. Use the brake cable inner as a guide. -
Page 19: Cable Routing Electronic Shift Controls
5.5. CABLE ROUTING ELECTRONIC SHIFT CONTROLS The 4ZA aero kit was designed to run the electric cables full internal. For you to route the cables correctly it is required to disassemble the TT extensions. The exploded view below shows an example cable routing. Check your setup position first to define which holes and spacers to route the electronic shift controls cables through. Start cable routing at the dot indicated on the exploded view. - Page 20 4za cirrus tt handlebar | manual |...

Page 21: Expansion Sets
6. EXPANSION SETS Expansion sets are optional sets used to enhance the adjustability and versetality of the 4ZA TT kit. None of these sets come standard with the 4ZA TT kit. 6.1. RISER SET In some cases, the highest setup of the extensions is not sufficient to accommodate an optimal riding position. In these cases the 4ZA riser set can be used to achieve a higher position of the extensions resulting in a higher riding position. -
