Ochain | R NERO and PREGIO for SRAM direct mount cranks (booth version)
will be shipped from May 30

Introducing the Ochain | R, the pinnacle of the Ochain range, meticulously designed for muscular bikes. This innovative product incorporates the sophisticated patented EASY system that empowers riders to fine-tune their riding experience by configuring the ideal "degree of freedom" right from its outer face from 0° up to 12°.

The Ochain | R represents the next evolution of active spiders, seamlessly enabling the chainring to rotate backward, effectively disengaging the transmission from the suspension. This groundbreaking feature not only enhances your overall riding experience but also elevates your bike's performance to unprecedented levels.

Awesome, bike feels amazing now

Quick few things. If you live in the uk I forgot about the import duties and it cost an extra £83. UPS charged £13 handling fee. Robbing gits and made it stupidly expensive.
I’ve since found out there is ochain distributor in the uk and you can buy from there. Google doesn’t show it and I had to put in ochain uk.
I’ve had the ochain R on my 2018 transition sentinel now for 4 weeks
When I first put it on I rode somewhere I don’t really ride much and didn’t think there was much difference, until I got home and looked at the prs I got on Strava.
Since then it’s just got better.
For normal trail riding I’ve had it in 9 degrees, but i did an enduro race and that was rougher (steep, choppy roots and drops). I tried the 12 degrees and that made the rear suspension feel bottomless. I don’t think I’m braking as much and the bike feels now the way I have always been searching for. Couldn’t afford a new bike and tbh I love this bike.
Just wished i hadn’t had to pay the import taxes

Incredible piece of equipment! 5 ⭐️!!

Well worth buying this! Easy to install. You notice the difference straight away. Riding feels smooth & floaty, even if the roughest of trails! My local trails are Fort William and it’s an absolute game changer! If you had an option to try one first, go for it! You won’t look back!

Absolutely amazing product! No more chain slap, better traction

I am in love with the new Ochain R, I replaced the last generation Ochain with this product. The new design allows me to quickly change the float and even lock it out. The fit and finish and beautiful, making the part a piece of art. I have been using o chain products for the past year and never had an issue. The float allows for the chain to bounce less, allowing for a near silent ride. After countless testing sessions, I can conclude that my bike has increased traction during heavy breaking and slow technical section of trail.


Great product and a great company to deal with.


So far so good.....had a concern about the engagement when pedaling but that never was noticeable. What is noticable is how well my feet feel planted on the pedals.... smoothes out all the chunky stuff! Feel more confident on the bike.
