    I'm looking for something like deity used to (still does?) do... just a 19mm splined sprocket to securely fit onto the axle. I'm not a fan of the slop and tight/loose chain spots I get with the usual 7/8" + adapter. I'd like a 25 or 26T ideally. Thanks

    the tree sprocket has a splined insert that matches up to the 48-spline spindle...it's pretty trick and eliminates the sprocket fixing bolt...

    That's pretty trick. But what problems does it actually fix? I've got the 48 splined axle on my Profiles, and I couldn't really foresee any problems, or am I missing something?

    lower quality sprockets that use adapters sometimes have enough "slop" that the sprocket isnt centered on the crank spindle. this causes the chain to be tight in some positions and loose in others. while this is really not a big mechanical problem with sprockets with "bmx cut" teeth, it is pretty annoying due to the chain slap that it can cause.

    a good quality sprocket with a 19mm bore (no adapter) will also eliminate this problem.

    Ah I read this then checked my bike. I totally get it now. If they made a 27 or 26 tooth I'd take one. But... I forgot if profile is 22 or 19mm/

    Profile = 19mm. Those are what I have.

    Man those tree sprockets are sweet, but spendy! $64...

    Yea I have one of the cheaper sprockets/adapters that has too much slop.

    If you know someone with a lathe, you should be able to get them to make you a nice, accurate adapter. I can knock one out in just a few minutes.

    OK, even if I could afford one, I wouldn't know the first thing in knowing how to use it. That's why you will make me the 48 splined adapter and I will pay shipping. Please and thanks.

    No can do on the splined part, but I can make you an adapter that fits dead nuts if you can measure your sprocket to within .001".

    Tree splined chainrings are the greatest chainring you can buy. I love mine. I am running a 22-12t now but picking up my 24t today. They are the only chainrings I will ever run.
