It seems there are substantially cheaper copies of the Nokon MTB brake cable set out there- IRD's Metawire (out of production, it seems), Aztec's Powerlines, and Alligator's I-Link. Are there any substantial differences between these?
Also, it seems like a few years back, a lot of people were using Nokon cables, and now there is a lot less talk of them. Is there any reason for that? Do these things make BB7's function better compared to stock Shimano cable housing?
