Ratio Tech 1x11 Wide range assemblyA conversion kit for allowing bikes running Sram 1x11 drop bar drive trains with a 42T max cog size to handle a wider range 11 51T cassette. Sram 1x11 drivetrains have been extremely popular over the last few years on all sorts of gravel and bikepacking bikes but have traditionally been limited to run a 42T max cog size.

A conversion kit for allowing bikes running Sram 1x11 drop bar drive trains with a 42T max cog size to handle a wider range 11-51T cassette.
Sram 1x11 drivetrains have been extremely popular over the last few years on all sorts of gravel and bikepacking bikes but have traditionally been limited to run a 42T max cog size. While that's a great low gear for unloaded riding, when you add camping gear or touring in mountainous terrain it becomes clear quite quickly that they really need a significantly lower gear. There are a number rof ways around this including converting bikes to run 1x12, but by the time you modify or replace the shifters the costs add up quickly.
Lately we have been increasing the gear range by combining the Ratio Sr52 Cage, a Deore 11 speed 11-51T Cassette and a new chain to make an incredibly affordable gear range upgrade.
The derailleur cage is compatible with mechanical SRAM 1×11 derailleurs with Type 2.x and Type 3 clutches including both road & MTB versions, as well as SRAM 1×12 Eagle derailleurs. Electronic Eagle AXS* derailleurs are not compatible.
The Deore Cassette is compatible with a standard HG freehub body, it does not work on an XD freehub body. Many bikes running Sram 1x11 drivetrains actually use a Shimano HG freehub body. A simple way to check is to look at the smallest cog, if it is a 10T then almost certainly you have an XD freehub body, if your smallest cog is 11t or larger almost certainly it is an HG freehub body.
Kit includes:
RatioTech Sr52 carge including special upgraded jockeywheels.
Shimano Deore Cs-M100 Cassette 11-51T
Shimano 11 speed Chain SLX Grade CN-HG601-11
A competent home mechanic could install this kit or talk to our workshop about having them do the install for you.
This kit makes a great upgrade for customers who have bought a number of bikes we have sold over the years, it is also relevant to a number of bikes we still sell currently.

Could be more durable.
Color: A-Navy
It’s not as durable as I’d hoped. I’ve had to mend it. It’s cute, though, and my dog likes it. He’s an Aussie, so not great bite strength.

Cute but disappointing
Color: C-Navy+Oak, Color: C-Navy+Oak
One of my dogs love these however they are far from indestructible. Two days after giving the teddy to him, the tail of the teddy is off and there is a rip by one of the arms. They are very cute teddies but not for heavy chewers as they will only last a few days.

Nothing is indestructible
Color: D-Purple
Adorable. Looks just like the photo. My 15# JRT loves it! however the tail and one ear were gone in a matter of minutes. It’s his toy so I’m just monitoring his time with it as it’s his favorite 😍

Our Pit Bull’s Favorite Toy!
Color: A-Navy, Color: A-Navy
We absolutely love this MAXBECK bear toy! We’ve ordered it 4 times over the last 8 months because our senior pit bull is obsessed with his “babies.” He always has one close to him and even cuddles with them.
The material is very sturdy and holds up amazingly well even with rough play. My dog’s favorite part is the squeaker. What I love most is that even after he finally tears into it, the rope built inside becomes a whole second toy for him and keeps the fun going.
If you have a heavy chewer who destroys toys quickly, this one is definitely worth trying!

Not indestructible
Color: C-Navy+Oak, Color: C-Navy+Oak
I assume it is probably hard to create an indestructible product, but my puppy had it apart in no time.
