The first link leads me to a wheelset that is 1250g...

I was initially trying to get a baseline price for weight-to-price. I readjusted my list for sub 1000g wheels. I noticed a price increase going below 1000g. Anything between 1100g to 1300g can be had for sub $500 usd. For sub 1000g price increases.

I'm starting to plan ahead and see what sub-1199g wheels are available to buy in the next few months.

On the low end I found sub 1150g 50mm depth, 24mm IW / 30mm EX wheels for under $500 USD:

On the high end, I found 50mm depth wheels that are 975g, but cost right under $1400 USD:

I'm a bit partial to anything in the 40-50mm depth range, but are still lightweight enough for climbing and fast pace on the flats. I found a couple in-between the $400-1500 USD price mark, but I'm open to other options. Any recommendations and/or opinions would be great. Thanks!

I'm in the UK so need to see if they are available here. Then how do they attach to a carbon crank? I presume there will be a spider that will allow for it.

It uses a special clamping setup, but it's compatible with 110bcd road cranksets. You can use a 4 bolt adapter or 4 bolt power meter spider to attach them.

there is a 12s version now with longer teeth, i ordered one from alix but im wondering if the pin that stops it rotating will fuck up the carbon cage on erx

I'm using the updated 18t narrow wide pulley wheel. I didn't want to spend money on an updated RD setup, since I wanted to push my v1 ER9 gearing to 50-34/11-36t with no compromise on shifting. I've taken it on a few rides where I tried sprinting at the high gear while trying to drop the chain, but it's held tightly. The older version could cause chain drop with 12 speed setups. It might even be more stable compared to my ERX v3 setup with wider cage.

I don't plan to ride this setup in the rain, but it is quite easy to disassemble and service. Also a steel bearing is available if someone wants to experiment swapping the ceramic bearing out.

I'd only get this pulley wheel if you're stuck with an RD that can't handle taking a bigger cassette.

Unless you really dislike semi-external cabling, I'm way happy with my setup. On sales it comes up as $400 usd or even less and that includes the seat post, drop bar and all the extra bits. The frame appears solid inside and out. No issues with brake mounts and the T47 BB is smooth. The money saved can be put into an electronic groupset, carbon crankset and/or a lightweight wheelset.

While I support more options, I don't see much advantage with this over LTwoo eGR or Wheeltop GeX. For road it's all about 2x especially living around steep hills and fast flats. I'd have to run a 9/10-46t chainring to make this groupset useful for me.

I mentioned in another post that I want to build up a G30U frame this winter. I have the frame inbound currently and next step is wheels. I am a big boy (120kg), so all the cool light weight carbon wheel sets are mostly rated at 120kg, which I will be over with bike weight and a good lunch. Are there any aluminum sets that are rated for more weight that folks could recommend? I spotted a DT Swiss R470 set locally for $300, that may be an option too, but I would prefer brand new with wheels, not someone else's issues.

Hunt Wheels sell alloy gravel wheelsets. There are some that are sub-1600g, maybe look into those.
