Pinion + Derailleur: 72 Speeds with 1,445% Range!?

why not pop the rivetes out of the cassette and swap the two largest cogs for two randon middle cogs?

Get the sturmey archer 3 speed hub that lets you put a cassette on it. Could have 21-27 speeds in the rear and 200+ gear combos

Each day we stray further from the light...

Maby put a Classified hub in. Rears x 2 😂

Real shame about the chain rubbing on the tire, I was hoping to see 10-14 gear inches 😂. I think Sheldon Brown has done something similar but with internal hub gears, cassette, and quad front chainrings.

I imagine you could put some chainring spacers on to move the chainring out more.

It's kind of weird that they put a hanger on there but no allowance for cable. Maybe they just have a generic dropout w/hanger that they use on all their bikes... Also, you could maybe eliminate the faster gears from the 10 speed cassette and space it out further to get use of the easy gears? But I know from running a 28t chainring and 52t cassette (fully loaded up steep hills) that the next weakest link becomes the freehub.

If the derailer breaks, it doesn't matter!

I had similar tire rub issues on my fat cargo bike when running 4.7 tires. I didn’t want to lose low end so I removed the small cogs and put spacers behind the remainder of the cassette. Why didn’t you do that? As you said, the high end is useless.

If i had this bike, I would run a 27.5" x 4.8" rear tire with the 24 x 6 on the front haha
that would be epic!

This idea was apparently concocted over a couple of beers. In fact I am sure "Hold my beer" was uttered.

New hub standard incoming: 300x15

Try replacing the 11T and 13T cassette cogs with a Shimano 14 T cog and adding a space to engage the lower gears in the cassette.

ex. PAIR. ih. ment.
learn it, milennials.
wtf is "expeeriment"? where did that unfortunate trend even come from...?

on a 10-speed cassette, you could remove the small stars and move the larger ones forward.

Cut the knobs off on the chain side and offset the rim to the left to grab a few extra mm.

Why not just remove the 12 tooth and like the 15 cog (or some on the smaller side) and add it at the rear of the cassette? This would move the two more important gears as 7th and 8th gear making them usable

Man this is some serious bike nerd shit

Sram Dual Drive in the rear!

THANK YOU! I soooo wanted someone to do this!!!

FWIW: In the early days of fat biking and pushing tire size, tires rubbing on chains was a common issue. We solved the problem in several ways. 1) This can work with NX Eagle on the Moonlander. You remove the third and 4th smallest cogs from the cog stack, placing them onto the freehub first. Then install the remaining cogs in the standard order. The 3rd & 4th cogs work as spacers behind the rest of the cassette. The first and second cogs are placed as normal on the outside to hold the cassette in place, and then you have 22-50T 7speed cassette with 12 speed spacing. This solves all the issues shown in this video, trying to get cassettes to work well. 2) We have hundreds if not 1000's of miles logged on fat bikes with chains that rub lightly on the tire in the lowest gear, surprisingly with no real detrimental effects as long as the tire doesn't have knobs sticking out far enough to catch the chain. 3) You can dish the rear wheel bias to the left side of the bike, away from the chain as far as there is room to do so. This can gain several mm more chain clearance in some cases. This does not detribmentaly effect the feel and handling of the bike. 4) You can carefully bend the bottom of the derailleur cage outword a few mm without changing the alignment of the guide pully or derailleur hanger such that the chain still runs fairly smoothly, the derailleur shifts perfectly normally, and the chain is again a few mm further out from the tire. Yes, this is rediculous, a low gear of about 10 inches and a high gear of about 120". It's fun and can potentially have some real benifits. Putting a 30T chainring on the 104 BCD spider (the smallest possible chainring) will provide a still lower gear.

I got my Moonlander yesterday, which I really can't believe! I was thinking about trying this...

3 speed sturmey archer hub

Am I the only one that hates large jumps in the rear cassette while climbing at slower speeds?

Loved this idea ❤

I'd be interested to know your thoughts on a belt drive. Having to "split" the frame and potentially have reduced frame integrity does not sound appealing. What is your view on whether a belt drive would be an improvement to this bike in the future or not? Love love this bike (but without the derailleur)

Garbage, pure garbage. Who the heck needs 72 speeds? Lets get real here. Someone, anyone please make a reasonable case for 72 speeds.

honestly on alpine mtb rides, you always run out of gears. might be a lot less pushing with a gear ratio like that

Dude’s bangin gears like a trucker. Gotta respect it.

Shit, now I want this bike.

You used to be able to get those anodised chain guides in the 90s that used a sprocket to keep the chain under tension for gnarly descents. How about a pair of those above and below the chainstay to angle the chain away from the knobbliest part of the rear tyre, that way you’d keep the widest part of the tyre, not lose any of the grippy knobs AND be able to use the 36 sprocket on the back.

Failing that, ditch the highest teeth from the cassette and fit a single speed sprocket (as they tend to have a wide flange on either side of the sprocket) as a spacer to enable the 36T sprocket to be reached w/out fouling the knobs?

Would not a smaller rear tire, say 4 inches, make the tire rub issue vanish?

72 speed lol 😂 unneeded overcomplication

Pick 9s cues 11-42 cassette (which is fact 10s cassette with built in spacer near big cog), remove two smallest cogs it will work with 10s deore shifter and mech.
Prob you need also longer limit screws.

(I also using similar setup on my commuter middrive ebike, really dont need small cogs with big 52t chainring)

man built a bike that makes gear calculator look glitched, I'm crying

Considering this is so bonkers! The best bit was the Goldberg variations!!

That sounds really stupid and crazy wich means i fully support it 😂

Mother of gear range!!!

now add a dropbar and smaller chainring and you have perfected the gravel bike. nothing more to add to gravel bike anymore after that.😀

This is my kind of tom foolery!

if he uses som spacers on the front chain ring to push it outwords it migth just work

I feel like I saw a reddit post about this recently about a weird customer asking for these weird builds...

Why a 6" tire??? Hell I don't even want 4" wheels...

Not leaving a tail on the housing and tucking it into the hole in the file box really triggered me 🤣

I’ve been thinking about doing this setup for months! Though I would use another internal hub in the back wheel like a rholfhoff.

Seems like a lot of effort to go through and not dial in the front chain ring.

So ... he got 72 gears, but lost low end pulling capacity, and gained a 298 gear inch upper end?!?! Amusing, but not very useful. Maybe he confesses to this in the 2nd half of the video that I didn't watch ...

Why not just buy the 12 speed casette made from single, unpinned sprockets and use the shortest freehub for just 8 gears.
It would have a tight chainline without rub.

Use the 7 speed cassette and spacers with the 10 speed derailler and limit screws.

I just want to run a Pinion with a Rohloff rear end. Super clean setup, but you'd lose a lot of efficiency with the system. It would be super fun though.
