Re: LTWOO ER9 & ERX - Electronic groepsets
Quote from: jac2689 on June 26, 2024, 04:13:41 AM
Howdy all,

I'm new to Chinertown and new to ordering from AliExpress/Alibaba in general.

I'm building up a frameset and think I'd like to use ER9/X but unsure of which sellers/distributors to buy from? Any recommendations?

I'm also struggling to match the prices others have shown on this thread for the parts. Any tips on getting good value?

And one other final question. If I buy the set without cassette/chainrings/rotors can I use pretty much any alternative brand? Is this the way to go to save some weight or am I best just buying the whole lot with the ER9.

Thanks for the help for this rookie!

Ha you're brave! Even though I'm running 2 ER9 groupsets, they are way to finicky that I wouldn't recommend them to anyone who isn't able to troubleshoot their own issues. First none of the AliEx stores are official, even if they have "official" in their name. So far the best prices for ER9/X groupsets come from the 80 Design Store or the LTwoo "Offical" Store . They were selling them cheaper on the AliEx LTwoo Choice store, but that stock dried up. Also wait to buy during sales. The next big one should be the AliEx summer sale. Though they've been running sales every 1st of the month with coupon deals if you miss that one.

You can run any cassette/chain/crank/rotor combo. You can even run different brake calipers if you want. Also you can save weight using a lightweight cassette, carbon crankset, lightweight 160/140 rotor combo and even swap out the brake calipers.

If you're new to AliEx bike building, I'd highly recommend using Shimano drivetrain components, because they should work with the least amount of hassle. I'd only start experimenting with the lightweight fringe components after you've become more comfortable. There's a lot of great stuff on AliEx, but there's also a lot of junk. For example if you start with 105 or Ultegra cassette/chain/crank components, You'll at least have some guarantee everything will work properly. Good luck!
