4. Brake lever setup
For the angle of brake levers, I find it best to set it up when you sit on the bike, with your arms on the handlebars and with a straight line from your fingers straight through to the shoulders. You want to have one straight line for both hands and then tighten on both sides.
On the SRAM Level Ultimate levers that Nino uses you can adjust the reach. On his bike I measure always the point from the edge of the grip to the tip of brake lever and adjust to 65mm.
