  • zr1 forks

    i really need to know if its even possible to remove tilite zr1 standard forks? I removed the caster wheel and the nut, now im trying to get the fork off and it isn't budging. this is time sensitive, so quick responses are appreciated.

    Remove the highlighted nut shown below and the fork should come off:

      Removed said nut. Fork is not coming off. Even tried hitting it with a hammer. Thanks for the quick reply though.

        They must be 'frozen' on then. My guess is rust is holding the inner bearing race to the stems. The forks should come off. Try turning the chair upside down, spraying some penetrating oil (e.g., WD40) around the base of the fork stems then tapping the forks gently with a wooden block for a minute or so to help the oil penetrate. Wait about a half hour, turn the chair right-side up, and try knocking the forks off with wooden blocks.

        This is why some users order titanium fork stems - they don't rust.

          Maybe try spraying WD40 at the top and bottom of the fork.

            WD40 and a RUBBER mallet, never know when those forks may come in handy again.

              Had the same issue with my ZR1 when I swapped out the forks for a set of Unitines. One fork came off with no effort, the other had to be pounded out due to rusting. I chose titanium fort stems for my ZR2 for this reason.

                Stephen,

                Are you happy with your ZR2? I'm trying to get one and the DME I'm working with is killing me becasue how long it's taking.

                  Crappler,

                  My ZR2 is a combination of the TiLite frame (polished with a fixed back) and a host of aftermarket parts (e.g., ADI back, Surelock locking hubs and camber clamps, Frog Legs Unitine forks and casters, custom carbon fiber seat pan and side guards). A lot of thought went into every feature of the chair and I'm completely satisfied with the result.

                  A little birdie, who shall remain nameless, informs me that the new TR3 is an even more responsive ride than the ZR2. If I was buying a new chair (and I have no plans to!) I would have to consider a TR3 as an alternative possibility, though I prefer the more open look of the ZR2.

                    I have a TR now, though it's 6 years old, so I don't want to go with anther TR.

                    I want to try the open frame thing. Did you post pictures of yours? I recall a real real nice customer ZR thread with pictures on it, I just don't remember if it was yours.

                      I had posted a bunch of pics in the thread I created after receiving the chair but for some reason they're missing from the hosting site.

                      Here's one:

                        Yep, that's the one. It is sweet.

                        Are the casters 4x1.5?

                          Yes, they're the 4". And I had the caster arms mounted to the frame a little lower so that there would not be as large a gap between the top of the caster and the bottom of the caster arm as there otherwise would have been (reference my CAD drawing).

                            I'm getting a custom back too; a Jay 3 I believe. Do you think its best to go with the shortest back height so the tubes aren't sticking up too much?

                            What's your injury level? If you don't mind me asking

                              Yes, I had the back tubes cut short. I hang a bag on the back of my chair which loops around the back posts (which are a custom 1.25" diameter tubing). If I could change one spec on my chair I would have made the back posts a 1/2" taller just for that purpose. As is, it's hard to loop more than a few grocery bags on the back without some struggle.

                              I'm a T4 complete.
