Ok, so I went with those TL-29's.
Haven't built yet but I'm really excited. They are asymmetrical, something I didn't notice on the website when I bought them, they're going to build into great wheels. At 555g for a wide 29 rim, they won't be taking any KOM's but I wouldn't be doing that anyway.
I did some mix and match, I delaced a wheel on my old gravel bike to get the Bitex hub off of it and rebuilt it with the Stan's 3.30 I had. So now I can use the Bitex on my mtb build. At 3.5 degrees vs 12 degrees, I think the mtb is the best place for that hub anyway. And I was able to reuse the spokes, so just a hub swap.
I've got straight guage spokes in the mail and Ill get it together whenever they get here.
So now the question is, since Kinlin rims are matte black with no logos and Bitex hubs are anodized black with no logos, should I bling them before I build?
I can get some pretty sweet genuine fake decals on the bay. Campagnolo? Hope? Easton? Dura Ace?
