I did torque them to 5Nm, but did not use any carbon paste on the clamp. I must say that during the first ride I had to change the seat angle and did this by loosening the front bolt and tightening the rear by the same amount of turns... Maybe this was not ideal...
Care to share what your favourite saddles are?

Little warning about this lightweight carbon saddle I bought... Rail snapped on the first ride. I am 64kg and it was a ride on asphalt, so nothing too rough....

Since it is hard to find much info on spoke sizing for these hubs I thought I would pen down my experiences here:

I have built 2 wheelsets with these hubs. For the first one (I did last year) I calculated the length myself and the spokes where much too long. I checked with the seller on Ali where I had bought the rims (since they also offered entire wheelsets with those hubs and rims) and they gave me the spoke lengths and they were about 2 mm shorter I believe... Those worked...

A few days ago I have built the second wheelset with slightly deeper rims and spend hours researching and measuring and calculating. I measured the drawings of the hubs in autocad to get the dimensions and I found that the flange distance that is stated in the info I found is mostly way too big. I measured the flange distance from the inner row of spoke holes to the center. The flange distance is way smaller than. Working with these measurements I ordered the spokes with a little fear in my heart, but they seem to be spot on.

For my 581 ERD sized asymmetric 30x30mm rims with 2,8mm offset (3mm larger than stated to account for the nipple head. I measured this myself with 2 spokes and the spoke threaded in the nipple flush with the slot in the head) I used 288mm spokes for the front and 286 and 288mm spokes for the rear.

• They didn't include a cable stop for mechanical front derailleurs, which they later shipped and delayed my build
• The handlebar/stem was failing to secure properly to the steerer tube which caused it to loosen up while riding (Scary sh*t!). I've built quite a few bikes and I was pretty confident that this wasn't human error, I later took it to a shop and they confirmed it. It was a long back and forth with Yoeleo's customer support that took months! They kept sending small parts for me to try out like the compression plug, steerer tube adapter, and stem bolts which didn't fully fixed the issue, the handlebar still loosened up but not as frequently.
• Since they were dragging their feet and refusing to replace the handlebar I had to take the loss and bought a handlebar from a different brand. I still had to buy an ST1 stem from them (which they offered at a slight discount   ) because the integrated cabling system doesn't play nicely with anything else
• The bike works fine now which proves my point that there was an issue with that particular handlebar/stem. They still refuse to accept that.
• I also discovered that the clamp that holds the saddle together was wearing out internally; The notches that help keep the saddle from rotating had all but disappeared. I asked them to send a replacement along with the other small parts they they were sending and they told me they would but they never did. When I confronted them about it, they blatantly lied and told me that they did ship it. At this point, I just gave up...
