Yeah I believe the kaly wheels also take a wierd size bearing.

I’d like to know if superstar/fivestar pulleys/hubs are interchangeable? For example, taking a unik superstar 44t pulley and putting it on a mbs fivestar hub.

@mishrasubhransu Cool, any chance you have these files available as STEP or some sort of solid works file rather than stl So I can take some measurements from them?

updated with pictures for trampa and MBS wheels, @Venom121212’s measurments. added a few others.
Anyone got any cad models for any of these?
Are you also interested in adding the weights of hubs and/or tires/tubes? I started weighing Six shooters, Bergmeisters, various MBS wheels, as well as 107/110 urethane wheels and the weight comparisons were interesting, and surprising.

@ducktaperules, i got measurements & info on 6 shooters and UnTrampas (Sumate) wheels for you. I’ll get the same for TB Nummies tomorrow.
Psychotiller 6 Shooters
Hub bolt center to center distance is 60mm with m4-7 10mm bolts.
Pulley bolt center to center distance is 47.5mm with m4-7 30mm to 40mm bolts depending on pulley width and offset.
6 Shooters use VEX VersaPulleys ( https://www.vexrobotics.com/htdversapulley.html) which can use 12mm or 15mm belts depending on the leaves installed. They come in 42t or 60t versions.
UnTrampa / Sumate
Hub bolt center to center distance is 66mm with m4-7 bolts. They can use 22mm OD bearings or 28mm OD bearing depending on the hub insert used.

Lol I am thinking of getting some of the UnTrampas
Do they ride pretty well? Or would you go for some of the MBS hubs and tires
Bergmeister, yeah ! Widest choice of full Alu gorgeous colored rims !!
• Weight: 392g - 0.86lbs per wheel & 163g - 5.7oz per hub
• 150mm diameter - 45mm width
• Made to fit standard 608 type bearings (They fit all longboard/skate trucks)
• CNC precision milled hubs made out of T6 heat treated aircraft grade aluminum
• Reinforced tire walls for max. inflation of up to 85psi)
44mm holes pattern diameter. (pulley step file available on haggy website)
Can fit TB218 and evolve trucks with 49T & 55T PULLEY FOR EVOLVE GT/X AND TB218 TRUCKS.
I made different wheel pulley. @moon too and @Janux-esk8 with rims too.
I aslo share a way to simply mount a chain drive on them with TB218 or Evolve truck (should work with BN220 and longer axle like FB230/240 etc).

They ride as good as any other nummie and better than most. Normally I would use MBS for an board with 8in wheels but It depends on what you wanna do.
If you want to use 8mm or 10mm axles these are a good choice as you can buy them with an insert that supports standard skate bearings.

I’ll find my calipers tomorrow and measure the kaly BX hubs, not sure if they are the same as a trampa hub or not
