Lightweight Carbon Handlebars (non-integrated) and a climbing wheelset recs?

[Merry]

I'm building a lightweight climbing bicycle (the Aethos) and has anyone tried those lightweight carbon handlebars, those that weigh <200g? Especially the Kocelvo 150g bars. The ones I'm looking at currently is this Ryet brand: https://www.aliexpress.com/item/1005001453428211.html?spm=a2g0o.detail.0.0.3515V7eVV7eVrP&mp=1. I've seen some topics discussed on how some lightweight handlebars are super flexy and have snapped for slightly heavier riders, but I weigh 60kg so I'm not sure if I should risk buying those flexy bars. Mostly looking for any firsthand inputs & recommendations.

Also looking for a pair of climbing wheels ideally 38 - 45mm, somewhere in the $1,400 CAD range.

Oh, I forgot to comment that I'm looking for some lightweight bar tape (haha, weight weenie goals). Anyone know any tried? Thanks in advance!

I'm happy with the RXL handlebars. They have the same geometry as 3t ergonova handlebars. Though they are light (sup200gr), they are plenty of stiff for me. I have them on 3 bikes (road, gravel). For reference: I'm 75kg and race bikes.  On a sidenote: I once bought the wrong size and as a test, I tryied to break (i.e. by smashing on the ground)-> I gave up, they were rock solid.
Search for "RXL SL 31.8mm Carbon Drop Bar Road Bicycle Handlebar" and you'll find them.

For wheelset: have a look at light-bicycle or farsports. They make custom wheels such that you can choose rim, hub, spoke etc as you desire. Around 1000USD you have plenty of options to go lightweight.

these flyweight rims are amazing.  they are designed as XC rims but too narrow for modern standards.  i am 100kg and have them build up as road wheels.  these rims, novatec hubs and pillar psr xtra spokes are 1050g.  i have ordered 3 sets so far and all have been at or under the 280g advertised weight.   if the link does not work search "fly weight carbon rim"

i found the bars to be great too.  very light and stiff.  they are on the same bike as the rims.  if the link does not work search "Kocevlo SL Road Carbon handlebar"  mine were right on weight wise.

I'm running RXL aero bars at 38cm that come in at 200g. I'm running the flared version because I like stability on the downhill and they give me more OOS leverage on the climbs. I paired them to a lightweight UNO stem that come in at 90g w/titanium stem screws. 290g with aero bar+stem. You can go with lighter bars, but you'll lose the aero tops which are a bit more comfortable for hand positioning.

Awesome, thanks! Looks like I’ll be going with the RXL bars. Maybe the aero tops instead because when I climb, I like to change hand positions from time to time.

I did also order and test these handlebars, no issues with the bars at 90kg rider weight.
It is worth noting, that I found the space in the drops quite short (shorter than on other handlebars).
It probably helps weight saving (186g at 42cm c-c), but I found adjusting and riding the handlebars hard due to the drops and finally swapped them out.
