While we wait for Shimano’s 11-46t wide range cassettes to become available, more companies are offering solutions for the existing 40/42t cassettes. Switching to a 1x drivetrain has a number of advantages, but most mortals still need a wide range with a large bail out gear. Although not quite as big as the  OneUp Shark 50t adapter, Ari is stepping in with a 48t cassette adapter of their own. Following in the footsteps of their other products, the new 48t is made in Italy and available in a number of colors…

Just like other cassette adapters, the Ari 48t cog works by removing one of the smaller gears from the cassette and installing the remaining cassette over the adapter. That means removing either the 15, 17, or 19t cog – or you could remove both the 17 and 19t and replace them with Ari’s 18t replacement cog for more even jumps up high.

The 7075 T6 aluminum adapters are offered in 13 colors and are available in models to fit the XTR M9000 11-40t, the XT M8000 11-40t, or the XT M8000 11-42t cassettes. Each cassette has a specific adapter for the best shifting and a claimed weight of 122g. Available now, outside of Italy the adapters will run €75 plus shipping costs.

I’m still waiting for someone to make a 11-36 11 spd cassette.

SRAM makes a 11-36 11 speed cassette.

Doesn’t fit on a Shimano mountain freehub though.

Yes they do- it’s the SRAM PG-1130 Cassette, regular HG Shimano freehub spline interface. It is 420g (11-36) however…

SRAM PG-1170 Cassette comes in 11-36, pretty light.

Geez, so the last 12 months of gym membership, leg presses, clean diet, hill repeats and CrossFit that enabled me to climb all the steep hills in my area with my current XTR 34T chainring with 40T cassette were for naught, and I could’ve just kept the fat gut I used to have, stayed on the couch all weekend long, and kept eating the burgers I used to eat, by buying this?

I sure hope Shimano responds to SRAM’s Eagle group by making its own PeregrineFalcon® 54T cassette.

No. It means you can put this on, and maybe bump up the front to 36teeth for even #morespeed

Let me know how you feel on the last stretch up to 12,000 feet up Searle Pass with your 40T and then tell me you don’t wish you had another gear or two. Not everyone lives at sea level.

Kind of heavy. Why didn’t they hollow out all that extra material?

What I’m wondering is if by chance they designed it to work on a 104 bcd, since it has 4 holes… We may not need another adapter on the market but we can sure use some more intelligent engineering with multipurpose products!

one my 1X Ive been running the following Shimano hack system for a month or so and it works great.
11-40 XTR 11spd cassette.
1-One Up 45T cog
1-One UP 50T Shark cog and cage
drop the 15T in 3 rd spot . Creates a 5T drop from 18 to 13 going from 3rd to 2nd. No big deal where I ride.
Shifts perfectly and gives a great progression at the top cogs when climbing. 40-45-50 is perfect. A little pricy for sure but relatively light and not available yet. OneUp told me it couldn’t work.
I have a 12T 1st position cog but need to shave a mm+ from the integral spacer so it will mate with a std 3rd position cog.

I like and have a XTR 1X (amongst other drivetrain) but this is getting ridiculous.
