Hi,
I used a junior hacksaw for my steel bars, took a little time.
Relatively it would slice through aluminium bars like butter.
I used a cable tie tight as a guide. Once you have cut off
one end use the removed piece as a guide to make sure
you set another cable tie in the right place for the cut.
Getting the angle the same is much easier with the guide
and the tension of a cable tie at that point of the bars.
My bars are very similar to the above, but because cable under the tape
will require a very tight brake cable bend I left my brake cables flying.
Also note in the above the levers are Brit style, front right, for a bike
intended to be US style, front left and back right, I'm wondering why .....
rgds, sreten.
