Soo, maybe an icons/creator fishing reel 3 in 1 set using the new 20T sprocket gear, maybe with a 2 speed gear box and adjustable drag but without damaging rubber parts

 You know, that's something I never thought of building but now that you mention it it could make an interesting build!

As a Ninjago fan I also wouldn't be surprised to see that sprocket gear in some sort of spinner mechanism before long (since getting something spinning fast and continuing to spin when it's released can be key for those sorts of play features)

Wow, interesting stuff! So apart from the massive wheel, we get:

- ~11L link, which will probably have some good generic uses

- 64T gear, which probably won't be useful in the average MOC, but should open up some new possibilities

- 20T freewheel gear, which seems really revolutionary! That seems like a seriously useful and unique part!

@Divitis and @2GodBDGlory:

This could be a chance to build your CVT ;-)

True, true!

Do we have any thoughts about that DBG new-style wave selector part? In the past when it was recolored from blue to orange, it was actually a different mold, with a different shift pattern. Any chance this is also a new mold, with a different shift pattern for this year's supercar? Or is it just a straight recolor.

This new gear might be used for radio controlling pneumatic valves as when the valve reaches its end point there wouldn't be any harm made to the system.

I don't think so.

The ratcheting mechanism of a freewheel doesn't work like a clutch gear (as e.g. in the white 24t gear).

So when the valve reaches its end point, the freewheel mechanism will still press on it, causing a lot of stress for the parts.

Or if you're rotating it the other way, there's only going to be a minimal amount of torque available before it starts to freewheel

You can easily calculate the exact tire and wheel size from this. Tires are 24.4cm in diameter meaning 30.5L and the full wheels are 22.4cm in diameter meaning 28L. Hailfire was 26.5L.

So they are bigger than the Hailfire Droid Wheels! Awesome!

Yes, that is also true. However, it's definitely a good part for making sure certain components can only spin in one direction, without having to build and rely on a custom ratchet. That opens the door to many new mechanisms that were not possible before.

Um, it might be not that usefull. In the real life you cannot pedal backwards and in the lego lifestyle video when he is spinning the pedals backwards the wheel is still like it should be. So if you really want to only make motorized pneumatic switch working one way it will be revolutionary. But you still have to manually switch the switch to lower the cylinder:). 

EDIT. Since i want to be sometimes really technical. Track bikes which rides on oval tracks and penny farthings plus unicycles and some ordinary bikes can have/has only fixie gear without any freehubs. That one you can technically pedal backwards thought its really difficult and the lego road cycle isin't a fixie so it will only work one way as the free wheel/hub should work:).

Ahh, I see, thank you!

The new freewheel gear clearly has an inner core with axle hole connected to the wheel (green) and an outer shell with the 20T gear (dbg). I assume it will be something like this in terms of main principle:

Interesting. Given that the setup is shown here is the most likely principle used for this bicycle's rear wheel, and given that the core is bright green like this, I am starting to wonder if this freewheel mechanism might actually consist of two separate parts, and this bright green core inserts into the silver toothed shell mold. Perhaps this could be the case? They could also be integrated into a single piece as suggested here, but if they're separate elements then that would magnify the utility of this new part, or set of parts. The green core would be a relatively tiny piece by itself, but this is an 18+ set after all, so it wouldn't surprise me.

I can use this freewheel gear in my next mobile crane.

I might be wrong but it looks to me as if the holes at the end of the spokes are slightly angled to allow for the offset - look at the shadows on the table. If so, this shows nice attention to detail, but I do wonder about wobble, and it will limit their usefulness for anything else.

Interestingly, the 64t gear will only mesh exactly in grid with a 16t (for a 1:4 ratio) or with itself.  Of course there should be plenty of scope for meshing with other gears at diagonal approximations to the right spacing, as usual.

Very excited about the new parts, in any case!

It's the same shift drum profile profile (checked both sides). Just a simple recolor of 3584 for "nice part usage" and possibly in the upcoming Koenigsegg 1:8 as well.

Nope. The pedals are dbg and so is the 4L axle with stop. It's just a brightened rendering side-effect. You can see the real color on the lifestyle shots better and compare to the lbg chainring. The chain is flat silver as mentioned in the other post.

Ah. I was debating whether it was DBG or LBG as a recolor didn't really seem necessary, but thanks for the correction
