So it’s plug and play with the rest of the V1 components?

I’m interested to hear how you go with this!

I can find no indication of it being an officially different version (other than the cage length). And it plugged straight in to the existing power and paired right up with the shifters.

New Version of LTWOO eGR Derailleur?


So, I wrote to my reseller (80 Designer Store on Aliexpress) about the charge problem. They promptly replied offering a warranty replacement for a nominal shipping charge ($15). Deal. But they 'warned' me that they only had the new, 10-50t version. Uhhhh, excuse me? Sure, send it. Awesome response

It arrived today (about a week). It is indeed a different version. The cage now measures 90mm bolt to bolt where the original one was only 83mm. That seems to suggest that it could support 50t now. But I cannot fine ANY reference to such a thing anywhere in the English web. The LTWOO mechanical RD can do it but the product page still says 46t for eGR.  I cannot observe any other differences to the earlier version (delivered in May 2024). It does weigh 15g more and 7mm of cage doesn't account for that. The app does not differentiate their versions either.

Has anyone else heard of an update. I've been looking at reports from Taipei bike show but nobody has mentioned it that I've seen yet.

Help with gearing?

I'm confused by Wheeltop saying minimum cog "10-11t". Does that mean 10t may have issues? Anyone with specific experience?

I'd like to get the additional occasional speed of 10t based on my browing of gear calculator. The 10t-45t shimano cassettes look good to me (even though I need microspline wheels), or there are 10-46t XD cassettes.

Better to be safe and stick with 11t?

I've been using mine with a 10-50 and an 11-50 (different wheelsets) both 11s. I don't notice any difference, both are fine. I suspect they wrote it that way to try to be clear that a SRAM 10 or Shimano 11 are both fine

Rapid drain or charge status failure


I did get my eGR remounted properly in the seatpost (vs external before) of the new (to me) bike. Thanks for the advice earlier. So much nicer looking that way.

BUT, I got an unhappy surprise on my ride today when it died.  I last checked via app about a week ago and it showed 65% I went on a 41 mile ride and hung it upside down for a few days. Went out this morning and it died 2 miles in. Once I applied power and could reconnect it was indeed at 4% dead. 

So it appears that one of two things happened:

1) 65% indicated is erroneous and should be considered very low. FWIW, I reinstalled it showing 74% and did not charge at that time. 71 miles later it showed 65% which seemed pretty reasonable. Deat at 112 miles. (I don't have shift count but that 41miles in between was a heavier than average shifting exercise. Note: I took the 'bring your own battery cell' approach when ordered. So I'm aware that a different cell than the manufacturer calibrated on (even in spec) could be the problem. But I suspect a lot of people buy it this way since the LiOn shipping costs are so high.

2) A wild theory: Hanging it upside down for storage keeps the motion-sensing RD alive and drains the battery. PURE THEORY but it seems possible.

Does anyone have thoughts?

heya lads,
have this going onto my ican graro.
I am having an absolute nightmare trying to dial in the shifting.
Using a Campagnolo Chorus 12sp cassette and chain.
A few days since I got it and I couldnt get every gear to sit nice to the point it would skip a gear.
Did it this way...... smallest cog initial calibration. Next cog -dial in. Move it back down and back up and so on but when I get to top 2 or 3 sprockets ie 27.29 31 it just wouldnt work.
Walked away for a few days and started back at it today. Had success until I got to 'gear 8' . Diallled in and went to move to gear 9 BUT the rd drops right back down to gear 3 or so BUT the app still reads as '10' . Hit the shifter again and it goes all the way back to 10 or 11!
Any ideas?
Buyers remorse is starting to set in!


edited to add;
I just tried to do it again. It wont even hold basic settings now.

It sounds like you might have a defect and it's worth reaching out to Wheeltop directly.

But when I read that the big cogs were the worst, I wondered if you have the 'b-screw' tension set correctly (to get the right spacing from cog to jockey wheel)

I just cut the bubble wrap that came with the groupset and taped it around the battery holder. I tied ribbon to the battery holder just in case it gets stuck in the seat post. No issues either with my gravel bike and 27.2mm seat post. It stays snug.

Good to know. It's a 27.2 and I was thinking of something similar (soft closed cell foam) but had not thought of the safety string. Where did you attach that so it doesn't just drop down?

I am seeing two different style brake calipers being sold with GEX, does anyone have insight as to the difference and if it is worth the more expensive/newer style blue ones?

Based on reviews, the biggest difference is aesthetic. I didn't see complaints on the old or new calipers. The new ones are widely reported as looking more refined in their design. I happen to think the new ones look better and more refined.
