NEW: 49T and 55T press-fit Bergmeister pulley —> fully compatible with TB218 and Evolve GT trucks

Top of the day boys n gals,

We got in stock (in very limited quantities!!!) our new press-fit pulleys

Each pulley is CNC milled out of a solid piece of POM and can be used on both Evolve GT and TB218 trucks. T he pulleys include a bearing(s) that ensure(s) a perfect fit on the truck’s axle.

For the Evolve GT trucks, we use for each pulley:

  • 1pc washer + 2pcs of 16100-ZZ bearings

  • 1pc of 295mm long / 15mm wide / HTD5 timing belt for the 49T pulley (when used with a 15T motor pulley)

  • 1pc of 320mm long / 15mm wide / HTD5 timing belt for the 55T pulley (when used with a 15T motor pulley)

For the TB218 trucks, we use for each pulley:

  • 1pc of 638-ZZ bearing

  • 1pc of 320mm long / 15mm wide / HTD5 timing belt for the 49T pulley (when used with a 15T motor pulley)

  • 1pc of 340mm long / 15mm wide / HTD5 timing belt for the 55T pulley (when used with a 15T motor pulley)

Both bearing types that sit inside the pulley and on the axle share the same outer diameter of 28mm….so they can be easily changed out to swap between TB218 and Evolve GT setups.

The area on the drive pulley where the belt runs on is very wide (22mm) with a single flange. To avoid having the belt move sideways on the Evolve GT setup, we will also include a belt retainer ring (spacer ring) to ensure that the belt is always perfectly aligned.

This retainer ring is not needed on the TB218 setup, because the motor mount itself can be easily adjusted.

The retainer rings in different sizes can also be downloaded here: https://www.thingiverse.com/thing:3855745

(Further .step files for different widths will be added within the next few days)

On the torqueboards option, what motor mount distance are you calculating the belt size on?

Edit : I mean distance from motor shaft to axle.

I recieved mine yesterday.

@Myke: sorry for the late reply. for the TB218 option (55T / 340mm belt / 15T motor pulley), the distance is 75mm.

I was able to set this up easily with the 49T on janux mounts using double idlers with a 355mm belt.

@FourteeOZ Hi Randy, in case the belt is moving towards the pulley’s flange, you can easily print out a belt alignment ring: https://www.thingiverse.com/thing:3855745

@haggyboard.timo it is actually fine, I could remove a couple speed rings if needed as well. That’s as far as I have seen it travel after riding it today. They arent staying on this board/mounts anyways :slight_smile:

Feels great, fits great though. Great product!
