LTWOO ER9 & ERX - Electronic groepsets

[toxin]

Er9, the weight difference is tiny

[Benbenben]

I placed the order on Ali for the er9, with the 80$ discount code ( I needed a few other things so I did reach the 500$ order), the er9 came to 350 USD with 80 designer store. Shipped to Canada.

This seems a bit concerning. Is anyone else seeing something similar?

This is my FD after roughly 2.500km of use. The finish wears away and there is this copper coloured layer below. Where the chain hits the cage, it’s basically polished down to the bare steel. But there’s no scrapes or ridges. So I think it’ll last. The black stuff is just wax. I’m not really concerned by these wear marks.

I see that your FD base is also worn out after driving 2,500 km, and I cover about 10,000 km per season, so it's scary to think what it will look like after a year of use. I think that after 2 years the FD will need to be replaced and this will add up to additional costs

[Sebastian]

I don't think I'd call that worn out. Maybe the pic makes it look worse than it looks in the flesh. It's really only the surface finish that's worn off. What looks like scrape marks is really only residue of wax and dirt. The metal itself is fine. But we'll see.
I got a Campy FD on my other bike that looks very similar. They put a sort of low friction coating on their FD cages to ease up front shifting. It wears off where the chain touches the cage which makes it look pretty horrible. But the thing is still fine after tens of thousands of km. I have no reason to believe that the chain is going to eat away the steel cage. But I guess we'll see.

finally pulled the trigger yesterday. 330€ without maybe customs was too temting. Has anyone replaced the breakpads by now and can say, if there is a shimano alternertive? and if yes which model does fit?

I paired my eR9 with ZRace XG caliper and Cooma Elite pads (the pink ones). I am just impressed with the Cooma pads. For the price, it has no business being so good and I have used all different kinds of Shimano pads before. I can comfortably say they are almost as good as Shimano's. Please note that I weight somewhere between 68-70kg, depending on the days, so that may change the results. Also impressed with the very minimal disc squealing noise.

Man, I am >< this close to pulling trigger on that $380 ER9 but the imminent launch of upgraded version is stopping me.  It's supposed to go on an existing bike (replacing mechanical Ultegra). But then in the comparison video on China cycling it appears that RD, cable port, charging port basically parts that have been reportedly suseptible to water damage are not updated and are same as current ER9/X. They updated FD but from what I read on these pages, the FD isn't really prone to getting the water in.

Was doubting but with the sale i've got a full ER9 group with Zrace rotors and Senicx crank for 500usd. I'm racing these bikes, curious how ER9 will react to the Belgian kermesse races ;-)

I also picked up the ER9 during the sale. Price came out to $350 USD with tax once I stacked it with $80 off coupon + coins. I decided to upgrade the rest of the drivetrain in the process so I picked up a 12 speed Goldix 251g 11-34t cassette and Senicx 52-36t chainring. I also picked up a pair of Fovno 12t POM jockey wheels for good measure. I noticed the cadence jumps on the 12 speed 11-34t matched the 11 speed 11-32t in the high gears and with a 36:34t low gear ratio, it'll match my current 34:32t 11 speed. I figure it's one of those scenarios where I can have my cake and eat it too! I've already ordered a set of high quality 14500 batteries and I'll probably pick up some dielectric grease from the auto store later on for insurance. Fortunately I have two road bikes, so I'll convert one to the ER9 and keep the other one mechanical Ultegra just in case.

let me know how it goes with the customs. I was thinking about buying that set but am afraid of customs here in BE

if your parcel gets stopped, they ask you for an invoice and charge you VAT on what you paid, plus potentially 10-20 eur for custom processing fee. They can't really fine you, if that's your concern. And worst case, you refuse the package, it goes back to china, and you eventually get a refund. There's a tracking number so the parcel can't just get lost on its way back to china, so you would get a refund.

Well first of all I'd like to avoid any custom there are some shops which do the XDB or so to dispatch things without paying it. Second, if it's like in PT, it's not just 10/20€. It's actually quite a bunch more. Here you can find a complete 105di2 for around 1000€. Taking the VAT off is sth like 830€ which puts it dangerously close to a complete ER9 build, with the advantage of being Shimano and warranty

Not BE but GER, but will let you know if it may help you. They package will arrive with transit throug NL. Last time (magene 505 base) the postman at my door charged me around 13€ on an 250€ order. But i can't rember what value they wrote on the package. This time it is 83€

I went through this thread and could not find the answer. Apologies if I missed it, but regarding the kit we need to bleed the brakes, do you guys know if we need a particular Ltwoo kit? I have the below kit that says is good for Shimano and SRAM. I was assuming that ltwoo would use the same fittings, but I am unable to confirm.
