I haven’t tried yet.  Just using an old Garmin 530.

Went on a 100k group ride yesterday.  Not the fastest group but did a lot of gear changes.  Mostly an endurance ride for me.  The EDS performed pretty well for the most part.  I did encounter two issues that I’m going to address this week.

1:  When I shift in the middle gears of the cassette there is some “noise/clicking” when I shift down.  Its almost like it doesn’t settle into the gear.  However, if I shift past it and then back up it goes away.  I’m going to play with micro adjust feature and see if I can’t fix it.

2:  At about the 80-85k mark the group started surging on a hill.  I was in the middle of the pack and shifted to maintain my cadence and match the group’s speed.  There was a loud metallic “pop” in the back.  I was shifting under load but not putting down crazy power.  I sounded like it came from the cassette.  Now real change in how it was functioning but I was concerned enough that I pulled off the group and rode in with a much smaller group the last 15k.  It shifted fine the rest of the way but I need to inspect the cassette and chainring for any broken teeth.  FWIW, all the components are brand new.  I’m hoping it was just a skipped gear or something.

Just my initial thoughts on the EDS RA6000 (carbon rim brake) groupset.  Up front, it’s working well for my intended purposes and after 6 days of continuous riding I am quite happy with the product for the price.  Time will tell how good of a groupset it actually is.

For a good overview of the groupset, I found Ribble Valley Cyclist’s review to be helpful:

I received my group a week early, which was a surprise.  No damage to the packaging.  Everything appeared to be in order.  Not a lot of instructions or extra parts.  It’s basically a mini grouppo, bring your own crankset, chain and cassette.  I pre downloaded the app.  For the first two days, I fumbled my way through the app, set up and tuning.  Translations to English are not the best but if you are familiar with working on bikes most of it should be self explanatory. 

I set the group up on a 14yro near mint Tarmac Elite frame that I’m using on my turbo during the winter months.  The rest of the year its my “training, travel, take to work bike”.  Despite it’s age the bike performs really well.  I had brand new 105 R7000 before I put the EDS on.  Running 50-34 compact cranks and 11-32 cassette.

Set up using the “Initial Calibration” feature on the app is really simple.  Mount everything, add the chain, set the RD on the smallest sprocket and move it slightly inboard till it rubs the next gear.  Back it off and set the limit screw.  Function test by moving through the gears and set the high limit screw.  All done. 

I got some chatter in some of the middle gears.  Took me a while to figure out the “fine tuning” feature but once I got it sorted, fine tuning has actually gotten pretty easy.  I recommend moving up or down in increments of +/-50.  You’ll know really quickly if its going in the right direction.

Performance wise, I am comparing this group to SRAM AXS Force (previous gen), Ultegra Di2 11spd, and Dura-Ace Di2 11spd.  I have thousands of miles on all three of those groups and have my opinions on all of them.  My opinion is that Di2 has always “worked”.  I’ve never had an issue with Ultegra or DA. Tuning, cassette, chainring swaps, all easy.  Battery life, never an issue.  SRAM,  worked great, hoods were a bit big, it was noisy and it took me a year to figure out how to prevent the dreaded FD overshift… but it was still a solid group.

EDS in comparison to these groups “feels” to me ever so slightly slower in shifting. Not like in a detrimental way, it’s just what I perceive to feel.  I am only using it in “Casual mode”.  I tested “Race mode” in the stand and it shifted much faster but it would skip 2-3 gears.  Also, Race mode is supposed to drain the battery quicker.  In Race mode it didn’t seem like the FD shifted any quicker. 

Over the last 6 days I’ve ridden between 20-30 miles each day.  No missed shifts, no chatter (after fine tuning) or hang ups. Riding hilly undulating routes with constant shifting. It was surprisingly good with zero issues.  Felt better than my SRAM Force if I can be honest.  The paddles for shifting are decent but don’t provide positive “click” like Shimano or SRAM when making gear changes.  Set up of the FD was easier than the RD and far easier than SRAM’s FD.  I set it one time, fine tuned it and have had no chain drops.  The FD is slow but it works with no drama.

Hoods in my opinion are ugly but functional.  They “work” but lack any real thought or ergo design behind them.  On the other hand, they are bigger than Shimano’s hoods and smaller than SRAM’s.  The rubber is pretty good too.

I did not take any weight measurements, however when I unboxed the group, each component felt heavier than I expected.  On the bike, it didn’t affect the overall bike weight by a large margin.  Both batteries came with about an 80% charge.  I charged them to 100% before started my tests.  After one week the RD is at 70% and the FD is at 75%.  I plan to ride until I hit 20% before recharging.

Couple of concerns and annoyances.  Spare parts, battery replacements, hoods are not available.  Every time you want to connect to check battery life or make changes to the group, you have to wake the system with the charging cable plugged into a power source.  There is no external wake feature.

I plan on putting the miles only this group over the summer.  As issues arise or anything happens of concern I’ll update this thread.  In the meantime, I think if it continues to work as is I will try it out with a 12spd set up in the fall.

I went through the other seller.  Initially, I was going to purchase from that site but got
a better discount with the other one.  Prices seem to fluctuate weekly.  I’m still testing my groupset before I provide some end user feedback.  So far, mostly positive. 

I assume:  You have the cassette selected to the correct number of cogs (11 speed)

1. Put your app into "initial calibration"  You should see a picture that looks like a cassette.  On each side, there are arrows.    Since your derailleur is stuck in a higher gear, you have to slowly step it down to the smallest cog. (Reads like you have done this process already.)   
2. After you get the pulleys aligned with the smallest cog, exit initial calibration.  Go into the "replace cassette" screen and first check that the settings are "11" speed.  Then select either 10 speed or 12 speed and save your setting for a different cassette and "Save"  Exit, then go back into the "replace cassette" screen and select "11 speed" and save this setting.   (This is a double check to be sure that the derailleur has "learned and saved" the cassette as an 11 speed).
3. Select "variable speed mode" and then select "fine tuning gear"  "rear".   Take a look at the screen to be sure you have 11 gears displayed.  Check to see the "1file" has a "0" setting.  Verify that the shift count for each gear is an equal value between gears. - Push on the "One Click Recovery" and reset to the default cog spacing.  (If it isn't resetting you have some sort of a problem I haven't seen before.)
4.  Exit out of this screen and go into the "Gear Shift"  screen.  This screen should show your number of cogs, and that you are in your smallest cog.    Shift into lower gears. (Past where it was stuck before.) Then shift back down to the smallest cog.   Repeat several times if possible.   
5.  Hopefully this solves your problem.

Tijoe,

Thank you so much for the quick response.  Yes, I was able to fix it but it was my fault not the grpupsets.  I paired everything first then started following the set up
instructions.  I had the FD on the small chainring…. A real smack my head moment. I didn’t have the chain on so it never occurred to me that the FD might be preventing crosschaining.

I got it all set up and did a preliminary test ride around the neighborhood.
Working out the kinks and fine tuning the gears.  In race mode, I seemed to get the
RD to skip gears with just one press of the paddle.  I went back to casual and the gear changes were more positive with no skips.  Race mode did not seem to make the FD any faster.

I have a more thorough write up once I get out on some training rides.  So far, I’m cautiously optimistic.

Thanks for the replies.  Sorry for the late response.  I have a lot of experience and miles with Shimano r7000 and R8000 mechanical groups.  I opt’d for the Empire set as an inexpensive way to get my wife’s bike upgraded from an old broken 10spd groupset.  I found that the FD worked but definitely not as good as a Shimano FD.  The left brifter worked on initial install but as I was tuning I encountered excessive tension while shifting it on the bike stand and it sort of “popped”.  I didn’t apply crazy pressure but it was enough to mess something up. 

I have gone around and around taking it apart as far as I could go.  I think I found the issue but it’s not fixable.  I think it’s just cheaply made and not reliable for long term use.  I ended up replacing it with an OEM R7000 minigroup off Ebay for 225.00.  Money well spent.  I will be avoiding Sensah in the future.

Yeah, price has been increasing due to the demand.  Regarding shipping, I had to msg the seller through the app.  They were able to turn on shipping to the US.  I didn’t order because of the price increase.  Seems to be an issue with their software.  Yesterday, I could put in my cart and get shipping.  Today, the shipping restriction is back on.

The only other place outside of Aliexpress I have found is, IceBikeHeaven.com.  With shipping from Maylasia to the US it was around 680-700.00.  I’m skeptical because on their Ebay store they sell the same set for around 900.00 USD.

I’m with Toxin on this, just wait until summer or fall when they’ve had a chance to increase production.  Maybe prices will come down a little and there will be more long term reports on it.

Rim brake versions are starting to show on AliExpress again.  Yesterday I almost bought one, had in my cart with taxes and free shipping to the US.  Held off, went back today and now both sellers will no longer ship to the US…
