    Mojo head angle

    I am looking at buying a mojo. On the Ibis website it says that the head angle is 69 degrees. Is that with a 140 mm fork? Does anyone know what the head angle is with a 150 mm fork (revelation), or a 160 mm fork?

    The rough rule of thumb is 1 degree for every 20mm adjustable fork travel change, or fork axle to crown change.

    Mojo has a 69 degree head angle at topped out travel with a 140mm travel fork with 520mm axle to crown.

    So you are looking at 68.5 with the Revelation. A 160mm fork has about 25mm longer axle to crown than 140mm fork, so about 67.75 degree head angle.

    The Mojo adapts without any pedaling squat efficiency loss to personal sag preference. Your sag adjust front and rear can bring close to 1 degree more ride time slackness.

    Great, thanks! Exactly what I was looking for.
