    Mounting Topeak Morph G pump under top tube with a cable running along the tube?

    Is it possible to mount the Topeak Morph G pump under the top tube if a rear brake cable is running along the bottom of the tube? (See the attached picture.)

    Thanks in advance.

    Yes, just don't clamp down on the cable. Route the zip tie, or clamp, under the cable.

    I still prefer the newer bottle cage mount. I had to buy one from Topeak, but it is still way better than their previous clamping methods. I hope it will become standard someday.

    Bicycleflyer is right. Just route the cable along the pump mount and make sure you don't ziptie over the cable. If you do, you'll discover the problem is short order Here's what it looks like

    Another less orthodox frame mount location is under the down tube. That is where I mounted my road morph before changing to a Specialized bottle cage mount, basically moving my pump from the underside of the down tube to the side of the downtube. I find top tube mounts get in the way when you want to just grab the top tube when mounting the bike on a car rack and such. I never had a problem with the down tube, just mount the clamps under the deraileur cables so they don't bind.

    I also have a Topeak pump (Road Morph) mounted under my top tube. It works fine.

    On my bike, the rear brake cable runs underneath the top tube offset to one side. Unfortunately, my top tube is triangular in shape instead of round, which means that the zip ties probably won't sit flush with the tube. From what I can tell, the brake cable might be making slight contact with the zip ties if I decide to mount this way. Is this bad? Will the cable fray/cut/get destroyed over time, or is this normal?

    cut a length of brake cable housing the length of your pump bracket and slide it over your cable in the area you plan on mounting the bracket. use electrical tape to secure the housing in place to the frame and then you can ziptie the pump bracket in place with the zipties over the housing without anything affecting your cable.

    The cable is steel, and shouldn't be damaged at all be touching a plastic zip-tie. I suppose it's possible that after thousands of miles, the cable would wear away the zip-tie, but I wouldn't worry about it.
