Looking to replace my brake cables/outers on my CX bikes (105 brifters and TRP Spyres brakes). Both outers (front and rear) run the full length (shifter to brake) on my CAADX so there’s a lot of outer there (i.e. lots of potential for compression). Looks like I can get a decent price on some Jagwire KEB (road pro) cables/outers, but also heard that it’s hard to beat Shimano DA cables (and I can get those for even cheaper). Haven’t seen much about Shimano cables for disc brakes online but it seems like a good cable is a good cable. Has anyone tried/compared both? Any thoughts?
Only use compressionless brake housing on mechanical discs if you want them to perform well and avoid problems with bottoming the lever against the bar. Shimano brake housings, even Dura-Ace BC-9000 as far as I know, are all the conventional spiral design. I've put KEB-SL housing on many Spyres and other mechanicals and it works great.
