The Spyres came on a Raleigh Tamland I had for awhile. I was perfectly happy with them. I never had to adjust them except for setting the lever pull to my preference. I appreciated that they never rubbed like I've seen on some hydraulics. Folks who know a lot more about brakes than I say hydraulics are much superior but I wouldn't be bothered by having the Spyres again.
Be sure you have the "new" compressionless brake housing where appropriate.
