LTWOO eGR

By chance, did you take pictures?

I haven't, but LTWOO has requested a photo and video of the failed bearings. I'll share here later when I have a moment to capture them.

Keep us posted...they usually keep asking, and asking and asking for many other things..but wont help...

I'd like to hear feedback, as well. I rode through some gnarly puddles and nasty muddy track exactly once (on a ride I crashed). When I did a post mortem examination some weeks later I discovered my lowest jockey wheel was seized. I squeezed some grease in around the bearing shield and restored some life. I ordered a random jockey wheel from Ali to try to replace it, but I'd be interested in knowing what the correct replacement jockey wheel is or can be sourced from. I emailed Ltwoo but got no response.

Curious what size jockey wheels are used on the EGR? Goldix have a few steel bearing jockey wheels and LTwoo seems to use off-the-shelf parts when possible. Would any of these match?

You can get the rear mech on its own no issues, electronic mech is about 250USD. They are the updated design as well.  So far, my experience getting parts has been excellent and I’m glad they’ve decided to make all the cables and everything available.

got my sram apex axs rd for $200, don't see the point anymore tbh. now that've eliminated the need for shifters and all you have to get is blips for $100. maybe the flexibility to go between 10-12 sp drivetrains is still a selling point. I've given up on these myself.

These look exactly like the ones on the eGR rear mech, but with black bearing covers. Note the 626Z metallic shield bearings.

See the photo below. Will try to get the video uploaded this weekend. The 626RS cost me $3 each at a local bearing ship.

Thanks for posting the picture. Made me go look up bearing code differences :-)

Seems like this might be worth doing as preventive maintenance. How easily do the bearings slip in/out? Is it a fingers job or would I need the right drifts?

So what do you use for hoods or do you use flat bars? I think 10-12 speed flexibility is still a big selling point for LTwoo and Wheeltop. SRAM blips with non-replaceable batteries just sounds like some first world nonsense. I might as well toss my water bottles after single use as well!

I used two sockets and a bench vise and they popped out pretty smoothly. One the same size as the bearing and the other large enough to support the jockey wheel and allow the hearing to pass into. You could make a drift with a bolt and washer and use a socket on the other side for the bearing to pull into.

Take care when pressing the new ones in to make sure they are even. My first attempt the bearing was a bit skewed so I had to remove and redo.

I've used it both w/a drop-bar canti cross-check and a flat bar mtb so far.
I think ppl have swapped coin batteries out in those blips, but it looks a bit surgical. like on a level of changing an iphone screen - not hard per se but fussy and time-consuming.

I just found a how-to tutorial on how to replace the blip batteries.

It would be great if someone could make 3D print of a case that's easy to access. Similar to swapping batteries on a cadence/speed sensor. I'd really like to see LTwoo or Wheeltop explore this option as well. Though I wonder how many patents SRAM has to protect this concept?

It reminds me of my cheap wireless doorbell, which basically does the same thing!

we are already working on this problem :-)

That's such a good point. I can't - for the life of me - imagine what stupidity went into the design with NON-REPLACEABLE batteries on something like that. If my $10 PAIR of ant+ speed and cadence sensors can manage to be waterproof, wireless, and have a replaceable battery then surely SRAM can do the same with a critical part of the drivetrain. Actually, it's worse than that. The pair of sensors I have uses the battery cover as a switch - turn the battery cover to the left and it's a speed sensor and turned to the right it's a cadence sensor. Not only does it have a replaceable battery cover, but they innovated a way to make it part of the interface.

Shame on SRAM, for real. Straight to engineer jail.

SRAM engineers probably did design it to be replaceable, but then the marketing department said otherwise! I can't stand companies that are market driven in this way. Shimano isn't much better, but I find SRAM much worst in this regards. I'm actually glad LTwoo and Wheeltop are now in the groupset market.
