    camber has to do with geometry..

    Centripical force applied to the angle.
    If you stand a straw upright on the tip, and apply side force to the top, it falls over easily.
    If you change the angle/let the straw rest on the side of your finger, apply force.
    it will stay more readily at the angle. The force is redirected downward into the angle.

    For your chair, with the increased angle/camber, when you turn the centripical force is absorbed by the camber and force redirected. Instead of to the side with no resistance, it's now applied down at a force equal to the degree.

    in other words.. it's good if your moving about a lot.

      well i think to make a chair as narrow as possible .you should first see the pros an conns .myselve still in my first chair that has a camber of 6 degrees and a seat of 17 inch wide .would go back to 2 degrees still good turning i think seat back to 16 inch .put the centere of gravety a little to the front +0,5 inch .put some spinergy lx with flexrims on it .since there is rubber between the rims and wheels .

      the pros are lot of space won eazier to get tru small spaces .the negative i think are it will turn little heavier plus more chance of hurting your hands .

      also now i have a 70 degrees front i would go to a 80 degrees front with a much smaller footplate .
      al by all i think this would be much better .another thing you have to think about is by ajusting your camber and nothing more your chair goes higher also and that could make it inpossible to get under a table with your legs .

      thats also the reason i would never choose for 26 inch wheels

        All that can be taken into account when ordering a chair and you simply set the front and rear seat-to-floor heights where you want, camber and and wheel size will not matter. Now if these are changed after the fact, yes it can make a difference, but if your chair is adjustable you can still address this.

There's nothing more frustrating than going to a friend's place, or staying in a hotel, and not being able to squeeze into the bathroom because my chair is too wide.

          She suggested that I have some camber. What do you think? Also, what else can I do to order the most compact chair possible? I currently have a TiLite ZRa that I have had since 2000, so I'm long overdue. I plan to stick with TiLite because I want a super lightweight, compact chair, but I'm thinking of getting a ZR because it fits slimmer in the front.

          That camber you`ve got is excesive for a daily use, don`t go for more than 4º, but i recommend you for a daily use 2º

            My apologies.

            Karl was kind enough to point out that I currently have a TR. [He's seen me in person, and the man knows his chairs. HA HA.] Interestingly enough, I had ordered a TRa. TiLite screwed up my order, along with my measurements, sent a chair that was not adjustable and definitely did not fit me, but I was pushing a dilapitated peice of E&J junk [circa 1992] that anything than what I had was a vast improvement so I took it for a discounted price. BIG MISTAKE. I will never again buy a chair that doesn't fit me like a glove. Hence this post.

            Based on your responses, I think I will request 2 degrees. Hopefully it will still be a tight enough chair to squeeze through airplane aisles. I used to envy my race buddies who didn't need to wait for a Washington chair to get to their seat because they could just wheel up to the front or second row and transfer, since their chairs were so compact.

            I'm going to try and snap a pic of my chair and post it here, and point out all the things I hate about it. Maybe you guys might have some suggestions on what I can request. In the meantime, I'm going to read up on all the options available with a TiLite, mess around with some images and see what I can come up with. Any feedback would be great.

            Thanks!

              I'm waiting on my Ti Lite TR from the states so hopefully it gets here soon. Ive been in this ZRA for 2 years now and didnt know what to look for in a chair so it was a pretty crap setup, too big for me and just didnt fit me well. So now i know exactly what i want and need. the tr ive been trialing fits me well, i look smart in it, very compact, every inch used.

              Technically the TR is the most compact of the Ti lites and i think the lightest, correct me if im wrong there.

              I also trialed the ZR but just preferred the tr because it looked tidier and more compact. i think the zr series gives you the option of adjusment which means more additional metal wear = more weight.

              TR is a very tight fit and i honestly look smart in it hehe. if your looking for the tightest, smallest, compact chair TR it is, i will upload pics when i get mine.

              I'm a skinny guy my measurements are 14" (width) by 16" (length) so im pretty snug in the chair n love it. i think you just need to use every inch so theres no unwanted or unused space like my big ZRA that is 18 by 18 i think.

              oh btw u and your lawyer friends are looking good hehe

                I'll partially correct you, the TR is the lightest of TiLite's rigid frames, but if configured identically, back, upper seat rail, front frame and caster location of both chairs should basically come out the same. Since the ZR/ZRa has no lower frame rail, some may consider it to be technically be more compact. Given that the ZR uses 1.25" tubing and the TR uses smaller 1" tubing and is a little lighter, some may perceive that it feels more compact. In reality, in an apples to apples comparison, both chairs should have nearly-identical footprints.

                A ZR will actually give you less adjustment than the TR. Both have fixed front and rear STF heights, but the ZR has less COG adjustment. If more adjustability is needed, the ZRa would be better than the TRa because the TRa has a much bulkier box frame than the TR.

                The TR does offer a "Travel Aid" option which is basically a modified anti-tipper with 3" roller blades. It may allow the chair to get through tight spaces, but only with the rear wheels off. Currently, they do not offer an optional titanium oar to be able to self-propel while the travel aid is in use.

                    Kiran in an E&J is a crime...but at least you can push it! I'd still be sitting there.

                    I think Ti did that to me too (21" seat???) and my Kuschall was advertised on ebay as an Air Pro. Which it's NOT.

                    But omg, it was only 17" wide, and rigid. I was happy to have it.

                      I have a Küshall Airlite Pro 13.5 x 16 and it will go through any door. But we can't get the Ti Light here so I don't have that choise. My cushion is 14x18 and is fitting in the chair. I have another 14x16 and it is too wide to go through the small doors.

                      We are using centimeters so the chair is 34x40 centimeter. The one who is too big is 36x40 so those two centimeters are making a big difference.

                        Since hanging out w/ Bente I think narrower = better. She is like completely accessible, none of this "Will my chair go in the bathroom?" And she FLIES, of course she's a para but cornering/balance/etc seemed to be no prob.
                        As for me ... I just need a smaller arse and that is proving elusive.

                          I'm in a ZRa and this the first chair I have had with 0 degrees camber. I thought it would be tough to spin around, but it isn't. If my tires are pumped up, turning is a breeze.

                              Steve, In your opinion how different is the feel of the ride between identically configured ZR and TR? Is it anything more than very subtle?
