Will FastTT aero handlebars fit my bike?
FastTT is the most versatile aero handlebar system available. Our universal bolt & ride mounting system enables easy installation of our aero bars to virtually any bike model, including mono-riser and twin-post systems. Plus, no mounting holes are required to be drilled in the bars.
Before you purchase your carbon aero handlebars it's important to plan how you will mount them, in order to include the correct spacers, angled wedges and mounting bolts in your order.
The following information will assist you in making the best product choice. For all of the following installation options YOU WILL NEED TO PURCHASE the appropriate length and diameter bolts to suit your setup. Click here for bolts.
The following are the most common mounting options for Tri and TT bikes...
TWIN RISER STACKS
Our bars will bolt to the existing twin riser spacers, plus you can add our adjustable angled riser for easy adjustment to bar angle. Alternatively you can replace the original OEM spacers with our spacer kit for a neat and streamlined finish.
When installing FastTT Aero Bars the original extension bars and elbow cups would be removed.

MONO RISER STACKS
We have adapter plates for most bikes with mono risers, which replace the original cup/bar bracket - learn more. Alternatively, you can mount our bars directly to the brackets where the elbow cups were originally mounted. Depending on your bike model you may require our adjustable angled riser to create the correct angle for your arms (some models have angle adjustment in the mono riser unit).
Height can be adjusted by changing the spacers supplied with your bike, extending the mono riser post, or fitting our spacer kit.

ROUND BARS WITH BOLT-ON WING BRACKETS
If you are mounting to round bars with bolt-on wing brackets you can generally adjust the angle of the brackets on the base bar to create the required angle for your arms. In this installation example the extension bars and elbow cups would be removed.
To achieve the correct bar height you may need to add spacers between the bars and the brackets.
