    What's your COG???

    After reading a thread and COG being the main topic I wondered what other's have their COG set at. I've got mine set at 4.50".

    So what is your COG set at?

    If you look through the CAD repository sticky you'll see lots of COG settings.

      True and I did but not everyone has a CAD drawing there. The question was just in general.

            17x16 TR3 3.25" (approx)

            TiLite says 3.5" is the furthest back the TR3 with the round back frame can be set, but I managed to set it back an extra .25" or so. 3.5 was okay, just a little tippier than I prefer.

              Keep in mind that the relative tippiness of chair is the result of a confluence of factors, not just COG: back angle, back height, dump, Schulte dimension . . .

                I always carry a loaded backpack, so my CoG is at about 2.25. And I grocery shop with a cloth bag hung on my backrest. When I have gallons of liquids in the bag, my chair is super tippy; I have to work to keep the casters on the ground (that's another reason I keep anti-tippers installed).

                  6-6.5" depends on which wheelchair.

                      Wow, that's incredible. If I had that when I looked up I'd fall backwards. Mine is 2.5. On an older chair with nearly twice the dump I had 3.25 and the chair was tippy as heck. Actually nearly fell backwards going at speed when I gave a big push. I like having a light front end, it's so much easier but I can't take the worry all the time. Mine is just right as far as how tippy I can make it and not have to be concerned about it. Even at 2.5, a backpack full of heavy groceries will make me tippy.

                        I call B.S on this one unless you are a double ABK amputee.

                        .. actually I think I got that backwards. Damn I still can't figure out how you balance with that much COG.

                          For those of you with a very-forward COG, how do you get up hills?
                          My COG is as far back as I can set it just so I can tackle steep driveways, grassy knolls, and cities like SF and Seattle.
