Reserved for now

I had a similar clamp on design like your mount. Problem here is the screw facing the street: f70b41ec70fce8d3eaf60bad0cd31abf71b8e13c_1_690x459

Keep it as narrow on the trucks as possible - best way is to have it facing parallel to the street! You´ll be hitting rocks and other stuff and this will wear down in under 500km. Worst case, you face the street because you catched something big - happened to me with this.


You can face the bolt the other way to gain some clearance. The mount itself is already narrow so by proportion it looks crazy stuck out.

Now that I realized it, the bolts are on the wrong way in my picture. I’ll fix later

To anyone interested in watching the process of making these:


Will these work with the racerstar style motors 5065 size? I know the mounting hole spacing is weird on them. I also apologize if this has already been answered a million times. My reading comprehension went to shit after my roaring twenties.

The idler one will work with that motor. The non idler 50mm edition will also work.

Will these fit on torque boards 218 trucks?

So which one do I choose on ebay?

The idler one if you want an idler, and the 50mm edition of the non idler one if you do not want an idler.

Unsure. They fit perfectly on standard calibers. You would have to do a little filing. The “pro” is that since it’s a 2 piece set, you only have to file a portion of the hanger, not the whole thing to slide a 1 piece clamp on in comparison.

Oh ok thanks

Bumpidy bump! Still many more available peeps!

going to order a pair.

what belt length would you recommend?

15/36 or 15/40 pulleys, I’d like to source belts that’d work for both

For the idler setup, the 2 belts I include, 320mm and 325mm will cover this ratios. If you are using big 107mm wheels though it might pose an issue as it blocks the idler.

320mm is good for 36t pulleys, 325mm is for 40t.

If you want to source your own 15mm ones then yeah hope that helps. Thanks

just ordered belts in a separate order, can you please send them in the same package? thanks!

The idler mount comes with 1x 320mm and 1x 325mm both 12mm wide for free.

If you want to order the extra belts I will include them, otherwise I will cancel the belt order.

oh damn awesome!

just send me the additional ones, like to keep backups on hand

So running 107mm and using idler pulley will not fit?
