    I have an aluminum beach cruiser and I am wanting to lower the seat by cutting off 1/2" or 1" of the seat tube.

    Will doing this weaken the frame in any way??

    Im going for the bobber look so I want my seat as low as I can get it.

    Let me know
    Thanks

    looks like you could cut it at the slot, or a little below it, and be OK
    don't forget to cut a new slot, so you can tighten the seatpost again

    you will need to lower the clamping notch too , i think as long as you deburr all the edges nice and smooth , it should be good . the clamping notch looks like the only issue to me .

    if you use a hacksaw to do the notch , use a round file ( or a dremmel ) and make it a nice smooth rounded shape at the bottom again - like the original notch .

    I cut the post down as far as i could on the rockhopper with a tubing cutter and then i cut the notch with a pair of good tin snips and it worked out great, good luck Tcams
