It'll be the TRP SPYKES you'd want, not Spyres. The Spyke has the same cable pull as a V brake. That way if you break a lever somewhere remote, you can use one off any old straight bar bike. No difference in cost, pads are the same. Also, make sure they spec very high grade cable, as someone else has said. I've got good results out of the Jagwire Mountain Pro cables.
