Sorry to be a bit thick possibly (and the info may already be somewhere within 28 pages!) but how do the straddle wires fit? Can you use one across from canti to canti or are 2 separate ones required? I ask this because I can see 2 grub screws at each end of the hanger.
I could possibly do with a pair for my winter road bike - which is actually a CX bike and the cantis are cr*p!
