Easy sprocket replacement

I recommend this product
ConsNone as yet
ProsAn easy life replacing or reversing sprockets
Only just fitted this with a new splined sprocket, no creaks or movement that I have been able to detect when riding. It has to be a great step forward in sprocket replacement, a couple of years of basically tightening the screw on sprocket every time you ride makes replacing or reversing a sprocket a much easier and less knuckle damaging experience

ConsA bit pricey.
ProsA neat conversion to improve your old Rohloff
Neat conversion kit. Was a bit of a struggle removing the old threaded sprocket, until I came across a YouTube clip showing a chap squeezing the chain whip and adjustable spanner towards each other one handed, rather than trying to push them away from each other with two hands. This conversion will make changing rear sprockets a doddle
A nice treat after struggling with screw-on sprockets for years

ConsNone really. Though you need the removal tool to engage the old threaded sprocket.
ProsMakes replacing a Rohloff sprocket MUCH easier.
I just replaced the original screw-on type sprocket with the splined carrier on my old Raven Catalyst. As I get older, I realize life is too short to wrangle the dastardly threaded sprockets any longer!
A worthwhile upgrade

ConsInitial cost
ProsMakes future sprocket replacement very easy.
This is becoming an essential upgrade as availability of threaded sprockets declines. In any event if you’re having to replace a sprocket it’s worthwhile because it makes future sprocket replacement/reversal a doddle. The new Splined sprockets are also cheaper and less bulky to carry as spares on expeditions. You’ll still need Rohloff’s so called sprocket removal tool and a chain whip if ever you need/want to remove the carrier.
Just the job

ConsNone really except the initial price
ProsShould be cheaper & easier to replace sprocket next time
Excellent quality as expected from Rohloff.
Easy to fit - once old sprocket removed.
My old screw on sprocket needed replacing so I took the opportunity to change to the splined version.
Good Upgrade

ConsQuite new on the market therefore not fully tested on very long tours
ProsNeat Solution
After a couple of times over the years trying to remove the original threaded cog (and succeeding with difficulty!), this solution means you don't need t carry a chain whip and big wrench on a multi-month or multi-year tour. The new replacement cogs are also smaller and easier to carry.
Fitted It And It Works Fine

ProsLooks like an easy job to change or reverse the sprocket in future.
I fitted it with no problems and it works fine. You do need the tool to remove the old screw on sprocket. (I Had one already.) It would be an idea if SJSC could offer a hire and return on that tool as you should never need it again.

8540S for Raven Catalyst too?
27 Jan 2020
Hi, replacing broken 16T threaded sprocket with splined sprocket on my beautiful raven catalyst - 8540S carrier too?

Thank you for your enquiry, yes you will also need our item #43202 Rohloff Splined Sprocket Carrier Slim - 8540S to carry out the conversion.
Kind Regards. 29/01/20

Hello I've just received my standard splined carrier 8540 for my 12 year old Raven Sports and will be using a 19 tooth splined sprocket to replace a 17 tooth threaded sprocket.
The information leaflet state's that the chain-line will change from 54mm to 57mm
So is it okay to use the standard 8540 carrier or should I buy the 8540S ?
you should buy the 8540S
