Crank arms

[games133]

Hi I've seen some hope red crank arms. But not sure what to get. I've got the standard ones on that are 165mm . But I have caught them on rocks and that. But not sure about 155mm option. Has anyone changed there arms.

I have a a cube 140 travel ad i changed my cranks from the e13 165mm crank arms to hope 155mm crank arms and now no pedal strikes.
Hope this helps from Tony.
