R2C TT Shifter Mount
R2C TT Shifter Adjustment
SRAM R2C shifters can be mounted directly onto some types of aerobar extensions. On open types of extensions you have to mount the complete housing with the internal clamp. Attention: R2C TT shifters have a bigger diameter than the SRAM 900 TT and SRAM 500 TT shifters. There are different ZIPP aerobar extensions for the different types of SRAM TT shifters.
The biggest advantage of our SRAM R2C TT shifters is the fact that they always return to their neutral position after every up- or downshift. To achieve the most comfortable and aerodynamic optimal position you can adjust this neutral position individually.
To adjust the SRAM R2C TT shifters follow these steps explained below:
To correctly install the SRAM R2C TT shifters follow these steps explained below: Adjustability within a 40°- range
• The SRAM R2C TTshift lever can be adjusted within a range of 40° degrees to match perfectly every individual ergonomical and aerodynamic requirement.
The correct extension for direct mount
• Please make sure, that the aerobar extensions on your bike match with the SRAM R2C TT shifters. • R2C TT shifters (below on the right photo) need a bigger diameter at the direct mount extension than SRAM 900 TT and SRAM 500 TT shifters (top on the photo).
Releasing the screw
direct mount
• Release the 5-mm-screw carefully to adjust the lever.
Internal clamp mount
• Nearly all aerobar extensions available on the market are suitable for the mount of the internal clamp of the SRAM R2C TT shifters. • We recommend our top of class ZIPP Vuka Aero or ZIPP Vuka Extensions.
Attention: Release the screw only as much as needed until the lever can be easily moved up and down. Do not release the screw more than half a turn! Attention: Do not try to shift when the 5-mm-screw is not tightened fully! mount with plug in
Change shifter position
• When the shifter moves easily bring it in the desired position. • Then tighten the screw again with 9 Nm (80 in-lb).
Distinguishing left and right shifter
• Left and right R2C TT shifters can be distinguished by their gear marks. • The left shifter for the front derailleur shows 4 marks for 3 shifting positions and one trim position. • The right shifter for the rear derailleur shows 10 marks for 10 shifting positions.
Mounting of the shifter housing
• If the shifter mount is not integrated in your aerobar extension mount the shifter housing in the top end of the extension. • Before you can do that you have to remove the 4-mm-screw completely and take the shifter unit off the internal clamp.
Fixing the shifter housing
• Place the internal clamp into the extension until it stops. • Use a 5-mm-hex wrench and tighten the internal clamp screw with the torque wrench to 8 Nm (70 in-lb) . • Pay attention to the correct operating direction of the lever.
Use of fricition paste
• In case the shifter housing is still moving in the bar, remove the housing again. • Apply some friction paste between clamp and bar to increase friction. • After the housing is mounted place the shifter unit correctly in the slot and tighten the 5-mm-screw with 8 Nm (70 in-lb).
