Yes, same width. About weight, in my opinion it doesnť matter in constant speed.

Go by look. Are these Light-Bicycle? I love my LB 35s.

LB is a good option, but I rather prefer Nextie. Classic clincher 45 (18mm inner, 470g ) or premium clincher 35 ( 17mm inner, 440g )

the 45mm deep rims will be stiffer and therefore all things being equal spoke life will be longer with the deeper rim. So go with the deeper rim.

Stiffer, cooler, yes. I am only interested about acceleration. Perhaps, 30g difference per rim don´t a noticeable distinction. At now, i have DT swiss R24 DB spline, which was weighed 1810g. Rim weighs 460g ( same, as nextie 45mm ), but spokes and hubs are heavier.
I want to try tubeless system, which is 50g lighter per wheel than tyre + tube.

You'll be ligher with a light clincher and light tube. I run Grand Bois Col de la Madeleine & Vredestein Latex on my light wheelset, 230g per wheel.

Ik have a set DT Swiss RC55 Spline wheels. The front wheel has DT Aerolite spokes en the rear DT Aero Comp spokes.
I measured with the Park Tool TM1 and noticed that the rear wheel has on the drive side scale 20 and the non drive side 10. The front wheel has scale 10 on both sides.
What's the tension that they must have, my wheight is 85kg?

Tubeless depending on the tyre offer other advantages that overall can make you faster. I dread to think how those compass tyres would have faired on this mornings ride.

I'm building a front wheel for my time trial bike with a 79mm carbon clincher rim from Farsports (DT240s/Sapim CX-ray), but something strange is happening when I inflate the tire. It goes out of center with as much as 3-4mm, and it goes bak to center again when I deflate it. Has anyone experinced anything like this before, and does anyone know why?

(It's perfectly round and center with an even spoke tension without air in the tire)

I am torn between Dt Swiss R460 and Mavic Open Pro UST: these will go with Miche Primato hubs and 32 dt competition spokes front/rear. Any suggestions ?

Wheels go out of dish when a tre is fitted and inflated not by 3-4mm. on tubeless rims I normally see 1mm of movement to the DS so I have to build the wheels with 1/4 turn of extra tension on the NDS spokes and fitting the tubeless tyre and inflating it corrects the dish perfecting on rims from 22mm to 50mm deep with the hubs i use.

The mavic open pro is 50g lighter the DT Swiss rims is cheaper. I like the mavic it is rounder than the DT rims. I have seen some rather up and down R460 rims. otherwise there is little wrong with them.

Thank you, but this is a symmetrical front wheel, so it doesn't help me. I've tried mounting another tire too, but it didn't help, so I don't understand. I've increased the spoke tension, and that helped, but it still moves around 2mm sideways. Any ideas?

What is the spoke tension then?

To around 115 before mounting the tire, and around 105 after. (According to my Park Tool TM-1). I really don't understand the physics behind the sideways movement, but can it be anything else than something wrong with the rim from Farsports?

Is it cheaper to build the wheels yourself?
