Description

R4 Rear HubThe R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings. We're using a tried and tested 4 pawl arrangement with 36 points of simultaneous engagement. What sets it apart is the large radius that the pawls are positioned on, reducing leverage at the point of engagement. We opted for a Chromoly steel axle for stiffness and longevity. Using steel allows a smaller diameter axle which in turn gives us more room

The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings.  We're using a tried and tested 4-pawl arrangement with 36 points of simultaneous engagement.  What sets it apart is the large radius that the pawls are positioned on, reducing leverage at the point of engagement. 

We opted for a Chromoly steel axle for stiffness and longevity.  Using steel allows a smaller diameter axle which in turn gives us more room to use larger, sealed bearings (we use USA made enduro bearings).  The rear axle assembly uses thread-on end caps which are easy to service and resist compression from the frames axle (they don’t fall off during trailside repairs either!).  R4 front hubs are available with standard or ‘torque’ end caps and rear hubs are available with XD, HG, or Microspline drivers.  We supply all parts for servicing to ensure that R4 hubs can be maintained well into the future!

Please select below which type of driver and/or end caps you need. If in doubt drop us an email. Spare parts can be found here.

Filters were not the right size!
While the roller brush and side brush are fine, the filters DID NOT fit properly, they were about 1/8 smaller on both dimensions than the original filter on my C10.

My Eufy C10 Feels Brand New Again—And It’s Cleaning Like It’s Trying to Impress Someone
If your eufy C10 has been sounding like it’s working but not really working, this replacement parts kit is the reset button you didn’t know it needed. After swapping out the filters, brushes, and rollers, my vacuum suddenly started acting like it just got promoted. Why This Kit Delivers: 🧹 Everything You Need, Nothing You Don’t – 8 filters, 8 side brushes, and 2 rolling brushes. That’s a lot of life for your vacuum. Basically turns one tired robot into a whole year of squeaky-clean effort. 🔧 Perfect Fit for the C10 – All parts snapped right in without forcing, trimming, or muttering curses. Side brushes spin like new, and the roller glides instead of thudding. 🌬️ Major Suction Boost – A fresh filter and roller made a huge difference. Dust, crumbs, and suspicious mystery fuzz are no match now. 🧼 Easy to Swap – Took less than 10 minutes to do a full refresh. No YouTube tutorials required—just a little common sense and maybe a screwdriver. Brushstroke of Caution: ❌ Side Brushes May Wear Faster – They work great but aren’t quite as thick as the originals. For regular cleaning? Totally fine. For warzone-level pet hair? You may cycle through them faster. Final Sweep: This kit brings your C10 back to life, keeps it performing like new, and saves you the drama of tracking down individual parts. If you love your robot vacuum but hate how it’s been slacking off lately—this kit is your fix.

Useless filters
Filters don't fit - they're way too small.
