Wish I Were Riding: I haven’t heard anything, but I’ll put that question to Arleigh to see if she has.

Are there any companies that are planning or willing to do 650B carbon rims?

Davidcopperfield: Yes, Scandium aluminum alloys are strong, but……….they are flexible! (See Salsa’s Dos Niner chain stay or their seat stays on the Big Mama and El Kaboing)

If Edge can construct a design that resists flex AND is light, well then that would be pretty amazing. However, the challenge is huge here due to the limitations of Scandium and the processes involved in making a bicycle rim.

I guess time will tell, but my initial response is that I am rather skeptical that Edge, or anybody else, for that matter, can construct a light and stiff aluminum alloy rim that would beat crabon fiber at its own game.

I contacted Egdes and they told that scandium version would be lighter, what do you think? Scandium will always be tougher than carbon.

A lightweight and simple trick that can be used for a recessed nipple carbon rim is to grab a bag of Velocity Velo Plugs and plug the nipple holes rather than use rim strips or tape.
Its lighter, stronger and allows for simpler truing.

I have used this set up for my roadie carbon rims successfully for some years.
sure – it doesnt make for tubeless but you can run a stans rubber strip over it without needing to lay down the reinforced tape.

just a thought.

thanks for the review – it is comforting to know these rims are proving to be tough and resillient – always a big fear factor with carbon components…
