All New Flywheel / Kegel Modular Pulley System Available Now!

I typically use 80mm, stock is 70mm. @psychotiller has 90mm axles, at least he did a while back.

Here’s info on 80mm & 100mm, I didn’t see any 90mm available.

To anyone using these , use a clamp or press to make sure that fucker is in

You can test if it’s fully flushed by putting it on the axel , ensureing it’s secured by the speed ring before it and nylon locknut after it. Spin it and if the pulleys spin is like a parabola (I don’t know the proper name for it) then on part is not fully flushed.

To make mine flush with a clamp I put small wood that covered the pulley (but not the wheel since the wheel was taller than the pulley) and clamp that fucker straight to hell. After that , a super nearly perfect spin

ok. here’s what ive come up with.

insert a 1/4" high 10mm ID spacer between the wheel bearing and the two bearings inside the hub.

add a third bearing into the pulley

and secure the pulley to the hub.

screw this assembly into the hanger.

this needs 90mm axles. fit is perfect. and having that bearing inside the actual pulley is super sweet.

Also, I made 2mm spacers, but I fucked up an operation in the CAM and all the holes were 0.5mm too small. FML.

do you have psychotiller press mounts? Clearance difference possibility?

Yes sir, thats the ones.

No, no press-fits. But! if you need 3mm simply replace the middle bearing with a 5mm spacer.

Yeah I’m getting them ordered. Though it would be easier to toss them in with my battery then pay shipping on $10 in parts, but I found more things I wanted from them.

For anyone that is reading the thread and confused:

They are using spacers to allow the pulleys to work on Surf Rodz trucks. If you want to use standard Caliber 2 trucks no modifications or extra parts are required.

@JLabs I ordered the 36t version and the hub installed very easily. It required quite a bit of force, but nothing too crazy. I’m using TB 218mm trucks with Abec 107mm wheels.

Thats awesome! Thanks for the support! Could I trouble you to leave a review? It would mean a lot! There are only 2 currently
