Current using this "OG-EVKIN HB-1300 Carbon Road Integrated Handlebar OD2 28.6/31.8mm " . It's really easy to cable and I really like it. Would be changing though as I found that the 100mm is too long for me, and I want to get a 70mm or 80mm but seems like the shortest for HB-1300 is 90mm.
Ah, for cables I just bought a file box of TRLREQ Teflon coated brake cables and shifter cables.
Cheap, I’ve got cables for years, and they do the job.
