    Lightbulb What do I need to put on these front casters?

    Hi guys,

    So I bought 4"x1" 2-piece billet aluminum wheels w/ soft rolls from Ti Lite and they are currently on my chair. I also have frog leg forks.

    I just bought 4" x 1.5" soft rolls from sportaid (red ones) to match my chair and I'm having issues putting them on because the ones I got from ti lite had 2 black pieces that kept the caster from running into the side of the fork.

    However the ones sport aid gave me were simply wheels with no spaces keeping the wheels aligned.

    The black pieces that ti lite gave me don't fit into the ones from sport aid.

    ANy ideas?

    Heres a picture with the new wheel that doesn't have the black spacers which leaves a big gap between the fork and the wheel which allows the wheel to slide around and rub against the fork.



    Heres the front caster that came with my chair which has the 2 black spaces which works great but the spacers don't fit inside the wheel I bought from sport aid.

    If I'm understanding you correctly, you need to take up the space between the new caster hub and the fork? Push the caster to one side (touching fork) and measure the space on the other side. Divide by 2. That's the size of the spacer you need on each side of your new caster. To determine ID, take one of the old spacers to a good hardware store and see if you can find tubing (will need to be cut), washers, bushings, ... ANYTHING that will do the job. A little slop is okay, but not too much. No matter how fast you roll, we are talking pretty low rpm's here. If the wheel binds it is too tight. If it wobbles or tracks badly it is too loose.

    Keep on the lookout for a really good bike shop that has a decent mechanic and fair pricing. In fact, anybody with tools who "gets it" can help you solve this and other problems. You might be able to trade your computer knowledge. It seems strange, but some guys who can rebuild engines can't install a printer.

    You need old school caster spacers. SCI_OTR posted a thread about the spacer change on the ZR2 here last week you should check out. You can just order the spacers you need from sport aid.

    I bought a set of caster spacers from sportaid, cheap...

    Tilite must have changed their design, I bought the same casters a few years ago, and they came with silver washers. The hub width for the 1" and 1.5" casters is the same. I often swop around my casters but never my spacers.

    You can get them with em yes, but if you don't order it that way they come with the 2 sided ones.
    Most everything I say is

    I found it interesting that they don't fit. The only way that would be the case would be if they started using something other than standard 608 bearings on their "performance casters" (ZR/ZRA S2 with billet hubs)?

    It got me looking into the parts manual.

    Sure enough, the tapered spacers use R6 bearings (ID=.375") while there other casters which don't use the tapered spacers still use the 608 bearings (ID=.315"). The R6 bearing is also required for any caster with their single sided fork.

    Unfortunately for you Cory, since your TiLite casters don't have symmetrical inside and outside hubs.



    A different width tapered spacer is used on each side (see table below, everything else requires CP103945).



    As a result, you can't simply transfer the R6 bearings to your FrogLeg soft rolls to use the tapered spacers. The hub width on the new TiLite "performance" aluminum hubs is also narrower due to the asymmetry.

    The good news? The double sided fork is still the same as the old model.

    Call FrogLegs or Sportaid and ask for the "FrogLegs wide axle kit". It may cost around $15.00, but you will get bigger button head screws which use a 5/32 Allen wrench and are less likely to strip.

    Lesson learned: If one intends to run 1.5" wide FrogLegs aluminum hub soft rolls, don't order performance casters and order 1.5"w poly casters if you intend to order the single sided fork. Sorry we had to learn this through your experience.

    This goes to a longstanding issue I have with TiLite. They make a high quality product that many end users are willing to pay out of pocket for. The cost of their parts has never been cheap, however, and it is extremely disappointing they continue to go with proprietary designs for key components that are not especially innovative but have the effect of restricting the end user's choice when it comes to replacement parts.

    Theres no such thing as a single sided Frog leg fork. I have frog legs and I the single sided fork I don't believe are frog legs (or I hope not because then I really did screw myself.)

    Thanks for the detailed info OTR
