They mention the eGR having no issue with waterproofing, I believe that the learnings would be transferred to the road groupset?

how much have you guys actually paid for ER9? I'm seeing 475 which imo is still not that good of a deal

Why? Cheapest 105 di that i can find costs around 750USD, it's 35% more than ER9, and with shimano you don't have shifting customization, like adjustment to each cassette cog  and various cassette speed. You literally get 105 di2 equivalent with a price 35% cheaper, and some risk of sudden death.

Around 450€ with tax (thanks to the declared value of 70€  ;D ), also paid roughly 160€ for crankset, 70-ish for Ultegra 11 speed cassette and also bought Sram rotors.

It might look expensive compared to 105 Di2, but 105 groupset costs 1000€ + I'd have to sell stock crank and buy new one (because Shimano doesn't pair 165mm crank arms with their groupsets), replace rotors with Sram or Hope (don't trust Shimano Shite tech rotors), running costs of 12 speed group are higher too

True. eGR seems to be sufficiently waterproof. I wonder what they did to fix it, though. Tighter tolerances? Is the difference in the cables and plugs. If yes, could 1st gen users just buy new cables? I mean, I really don't have any issues with er9. But it would be good to know.

I've ordered the e-gr groupset but now I'm a bit confused. The graphic on the AliExpress listing (official ltwoo) says max 50t. Trace velo seems to be running a 50t. All the official website comms and the user manual says max 46t.

Which is true? I need the 50t capacity.

They most likely say 46t to play it safe with tolerances. Even the big brands are known to be conservative on their max capacity numbers. It may not work in all situations with a 50t, so they say 46 max.

I wonder if everything is backwards compatible between the 1st gen ER9/X and blue edition? Also did the latest batch of ER9/ERX get the blue edition weatherproof fixes? I wish LTwoo was more transparent about the changes. I think Wheeltop and Sensah should still try to win marketshare in the Chinese electronic groupset market. Internal competition should keep LTwoo in-check especially if the competition offers a more solid product with better customer service.

That was a huge miscalculation on my part, I assumed drivetrain was more expensive. I thought the bare minimum with YBN chain, senicx crankset and ZTTO cassette would end up being ~850 for the groupset which is straight up uninteresting when you can have resale value, service and reliability of 105 for not much more. But individual trim, replacable battery and sleeping at night knowing you didn't give shitmano a cent make ltwoo an interesting option, too bad I built my bike just before it was anounced.

But how much can the ER9/ERX mech clear? It's rated for 32T and I know joe said 34T was fine but can it clear 36T? Also when you buy the "no battery" option, does this mean you still get the battery holder and have to buy the batteries yourself, or do you have to buy a battery case? And does anyone know if ER9 will be updated to "blue edition" at the same time as ERX?

I think officially it can only clear 32t. I'm using it with an 11-34 cassette and that's fine. Not sure if it can handle more. I think you could try and set it up with 11-36 but if the RD parallelogram curve then ends up with the upper pulley too far away from the cogs in the rest of the gears the shifting will suffer.

I have 34t with no problem,  think 36 t would work, or maybe with a roadlink.

I don't have the groupset, I want to make sure it can take 36T before I buy. Do you still have room on the b screw?

Confirmed 46t max. Am I right in thinking a hanger extender will allow me to use my 50t without issue?
