I'm looking to buy replacement cantilever studs...and I found a couple.

One is from Nova cycle supply, but I can't buy online. I have to call the credit card number in. It's an Easton Aluminum stud.

The other is on bikemannetwork. It specifies it as a Salsa stud for Scandium frames. Does that mean I can't use it on my Aluminum frame? What makes it for Scandium frames only, if anything?

Thanks!
