Still loving my metzler z6’s, installed 2 years ago. Felt like riding on rails after the scrub-in period. Wear was much better than expected — but may not be as aggressive as other riders who report shorter tread life.
But am gearing up for new tires and may check the recent reviews in Bike or elsewhere (perhaps a year ago) on Metzlers and many other common brands for these sorts of bikes. Good luck.
