These are clip on or screw on arrow bars.
You can buy some that actually clip on your bike. These are actually going to screw into
the handle bars of your bike and they are going to sit at the top of your bike up here.
Once you’ve had them properly put on, you are going to put your arms here and here and
you will ride down like this. The benefit of riding in this position is that you are
more arrow dynamic. That is why they are called arrow bars. Now this is a good way to start
if you are interested in trying time trialling. You would never use these bars in a road race,
criterium race or circuit race; only in time trialling and triathlon. I would recommend
starting with these types of bars on your regular road bike, deciding that you love
that and then investing in a time trial bike.
