The Flyee ticks all my feature boxes and price seems reasonable compared to other mid-tier options. ICAN customer service also seems very responsive. Though the frame is still fairly new and not much user feedback yet.

Easy, you can buy both an HG and XD freehub from Elite Wheels and jump back-n-forth depending on your choice of cassette. HG goes 11t smallest and XD will get you to 9/10t smallest.

Actually I asked a somewhat similar question in the components sub-forum, but I'm wondering if the 9t cog is any good in real-world use!

Maybe if they added new features like wider tire sizes and possible perks such as UDH or a threaded T47 BB, even then it's not really a necessity unless something is holding you back from your current frame. Better off investing that money in either wheels or components that will help your performance.

VG Sports does make a 12 speed XD 10-46t, but it's ridiculously expensive for what it is:

The other cheaper option would be to get a 12 speed MS 10-45t from Shimano. Though all these options would be severely compromised on a 2x setup. Perhaps you could go with a smaller chainring setup to make it happen.

I went from a 2x mech to 1x eGR. Because I've had no issues with mine, I would say yes, totally worth it. It meant a lot less hassle routing cables through the frame, and the shifting once dialed in is flawless. But it's worth bearing in mind that this groupset I think can still be considered 'in testing'. I'm not sure I would have the confidence to take this bike packing on a multi day adventure and feel secure in the knowledge that there will be no issues.

Both my road bikes are running Ltwoo ER9 and they've been running flawlessly. I've been tempted to go electronic with all my bikes, though I'm hesitant with my gravel setup just incase something happens while I'm on a remote trail in the mountains. The other thing is I'm not entirely convinced I'll stay 1x, I also like 2x gravel as well. I'm currently using  2x Ultegra shifters, so it'd be easy to drop a mechanical FD if I switch back.

I like this frame if I were looking for an all-arounder. Though for a climbing frame, the ICAN FL1 frameset (Aethos clone) is cheaper and weighs 100g less. It has almost the same features of T47 BB, 32c tire clearance, but no UDH. Also ICAN customer service seems pretty good. I would definitely consider buying from them in the future.

I went on a buying spree during the back-to-school sale, but mostly small items and I really need bike parts for school! 

First I picked up a few Pass Quest aero chainrings. I don't think they make me go faster and they're a bit noisy in the low gears, but they look cool on a 1x gravel build: https://www.aliexpress.us/item/3256805802961930.html

I also picked up a few Goldix chainrings, because I like having options. On Pick 3: https://www.aliexpress.us/item/3256806852034023.html

I bought a few sheets of faux CF protection decal protectors. They're relatively lightweight and since all my bikes are black, it's a good way to protect my bike frames, while being relatively weightless. Also the adhesive doesn't leave any residue and during the sale were under $1 USD on Pick 3 (used to be $1.99 USD for 3 sheets): https://www.aliexpress.us/item/3256806808805802.html

I picked up these cheap ABS plastic SPD pedals. I normally use lightweight road-like SPD pedals, but I'm planning to swap cranksets out for different 1x gearing options when specifically climbing the trails. I prefer these pedals because the plastic doesn't scratch/dent surfaces (I owned them before, but gave them away) and I don't really care for those fancy alloy MTB pedals: https://www.aliexpress.us/item/3256806124459641.html

I've mentioned this base layer on the Chinese cycling clothes thread, but I'll drop them here. I'm a big fan of these inner mesh tank tops. They're cheap and effective at wicking away sweat on hot days and keeping me a bit warmer when temperatures drop. On Pick 3, they're less than $3 USD a pop: https://www.aliexpress.us/item/3256806910751768.html?

I bought a pair of these aero socks with a silcone non-slip grip. I didn't have high expectations, but after trying them out they work extremely well. Though I'll have to see how they hold up after a few washes: https://www.aliexpress.us/item/3256806824187391.html

I also decided to try the Spedao lightweight 11 speed 10-42t cassette. I had a so-so experience with the Spedao road cassettes, but I'll see how this cassette will handle. I mainly got it for the 10t cog, just so I can run slightly smaller chainrings on the gravel bike: https://www.aliexpress.us/item/3256806211398285.html

Lastly I ordered (okay, not a small purchase) this Easedon wheelset for my climbing road bike. I opted for the lightest configuration of sub 1200g. I don't really care for aero, since I mostly climb anyways. I'll report back to see if they're any good: https://www.aliexpress.us/item/3256805991276022.html
