Not sure why the width is even there (in-mesh surface area, maybe?), it doesn’t make any difference on the belt length.

Oh yeah I guess that’s arbitrary info for our purposes lol

3277

Sorry I’m nOObing it up tonight - what’s the center distance determine again? Less distance between pulleys, more torque? Or what’s the deal there again?

3278

Center distance doesn’t affect your gearing, only the pulley sizes (ratio) do.
You only need the center distance to calculate the belt length for a given setup.

More torque = bigger wheel pulley and/or smaller motor pulley
More top speed (to the extent your power budget allows) = smaller wheel pulley and/or bigger motor pulley

Probably because that company doesn’t sell that specific belt cut in that width.

I just noticed you wrote 160 mm wheels but it says in the calculator screenshot 83 mm

good thing I’ve got this thing to cut whatever goddamn width I like :rofl::rofl:

Anyone can chip in some opinions before I go ahead with my purchase :smile:

Do they have slightly longer axles too?

To be honest, cast is cast. No difference except for extended axles which is pretty much needed in esk8. Beat me to it @Skunk

Longer axles like Caliber E except also longer hanger, unlike Caliber E.

I prefer shorter hangers for ride quality but mounting motors usually requires a longer one unless you want to put some real work into making sure it will all fit as narrow as possible.

3286

Yes they do, but I don’t need them on my setup, so does that means there is no need/benefit to upgrade?

My setup consist of a dual 6354 with 12mm belts and they fit just fine on the current caliber 2 trucks I have, so if that’s the case, there isn’t a very solid reason to upgrade to the tb218 isn’t it?

Ditto the above comment, so a shorter hanger actually give better ride experience compared to the extended tb218?

3287

Well, personally, I like the calibers because smaller trucks give me more control over the board. I like the tb218 because of the extended axles and that’s about it. The tb218’s profile is a little larger too so you would have to modify your mounts or hangers. Both good trucks. I would definitely switch angle baseplates too

center distance can affect pulley wrap, and thus the number of teeth engaged. In extreme cases (huge wheel pulley, tiny motor pulley, very close to each other) you can have very small engagement of the motor pulley.

The farther apart they are, the closer to being parallel the belt sides get, so the belt wrap approaches 180 degrees.

I see then I guess there’s no point changing to the TB218 if my caliber trucks works fine now :+1:

@Venom121212 More torque = better mountain climbing and steep hills?

hopefully this makes it more clear:

^to a close approximation, anyone with 4 motors regardless of kv or tire size (who is also running 42.1 volts) can obtain this performance by adjusting your gear ratio such that your no load virtual ground speed is the same as the no load virtual ground speed shown on the chart at the bottom.

And just in case you’re a normal human who doesn’t want to scour conditional graphs,

Yes. That is correct.
