get LB 46 rather than a LB 45.
...... normally the reason people use 45 against 55 is not the weight, it's the handling safety in wind.https://www.lightbicycle.com/Road-bicyc ... lable.html
That's great, detailed advice thank you - do you use them? I see the 46 is V-shaped not U-shaped.. Much difference in performance /handling? Just applied for a quote... Fingers crossed I can afford them!
Enve rolled back to V-shape on their modern wider wheels.
Reynold and Campagnolo (mostly) doesn't get on U-shaped trend at all.
Apparently companies realize that Brake track end must be wider or at least close to tire's width for the best aero performance.Rim must not be crazy wide (>30mm) to maintain compatibility with frame and brake calipers in the market (at least for now). U-shape get narrower at brake track while modern V-like shape (it's not really a V but close) is wide there so it perform better for wide tire. Stability is good too if it is properly designed. Reynold 58mm test way better in stability than Zipp 404 (60mm) in Tour megazine despite being V-shape is a good example.
I use it. One rim in the front as i only need front rim replacement while my rear is still good. It perform perfectly and really stable. When my rear rim need replacement i'll go for wide rim like this too.
If the price is too high, drop the hub to dt-swiss 350. Either front only or both. There is only small weight penalty there. Or you can use Novatec hub in the front but Dt-swiss in the rear then it'll be lighter. Front hub is simple enough that most of the time you don't need fancy hub.
PS. you said you normally ride in Thai? I'm Thai but living in Louisiana, USA.
