How to install the non-aero lever and cable

Do you want to build a bicycle or do you want to assemble a bicycle from parts? If you are asking how to build a bicycle then just by asking the question, you can’t. It takes knowledge of geometry and general knowledge.

For a vintage bike enthusiast, you don't need to go to a shop to upgrade your bike. It's more fun doing it yourself. And I’m going to offer you some tips for installing a new non-aero lever and cable.installment, non-aero lever and cable

Slide the lever all the way toward roughly where you want it to be on the handlebar and clamp it down. Most of the time, the levers are marked left and right.
Use a straightedge. Line the straight edge up with the flat part of the bottom of the handlebar. The bottom of the non-aero lever is just going to come down and touch the straight edge. That’s where you want the brake lever to be. For personal preferences, you can adjust it a little bit but this is generally the starting place. Besides, look to make sure that it’s lined up straight forward from above. And then you can clamp the non-aero brake levers down. Do the same on the other side.
You will need a set of Allen keys, a new brake cable and a good pair of wire cutters. You need to make sure that you have the correct cable- check the nipple at the end of the cable and see that it matches the original cable, and sometimes a ferrule is needed. Thread the cable through the fat opening of the lever facing down and push it through the narrow opening facing up.
Install the piece of housing in the correct length with a pin to spread the end. If it’s too long, it could create too much friction or it should just flop all over the place. If it’s too short, it may pinch and not work properly. So when you’re installing new cables in housing, you would make sure that there’s as little friction as possible.
Thread the cable all the way down towards the brake where the nut and bolt are, righty-tightly. Then pull the brakes tight to where you’d like them to be and get a five-millimeter hex wrench or Allen wrench.
Press the brakes in and tighten the clamp bolt on the brakes down. Put a little crimp on the end and squeeze it on.
Check the brake and make sure it’s working properly. If it’s too loose, tight it up a little bit. If it’s too tight and hitting the wheel, then you can loosen it. On a lot of brakes, there are adjustment screws if the pad is a little too close, you can adjust this screw with a Phillips head or an Allen key and basically, if you loosen it, it loosens the tension on the side. You tighten it, it tightens the tension. So you can get the brakes nice and even so the wheel rolls in the middle perfectly.installment, non-aero lever and cable
Do the same to the back non-aero brake lever. Remember to get the cable through the little cable holders on the top tube.
