I like the 4000 S II 700C tires well enough that they're the only ones I buy. I bought two on sale at half price to keep in reserve for when the others wear out-eventually. The price was too good to pass up on tires I prefer.
These are my go to tire. Love the 4000s which just retired and have the new 5000s. The 4000s sidewalls has a tendency to blow after so many miles though. These 4 season have good flat protection, good roll and great grip. Rode 4000s and dura skin for years. These are all I ride now. I put on 10000 miles or more a year between commuting and weekend rides and good wheel sets, tires and saddle make all the difference.
I use Continental Gatorskins on my road bikes. These Continental Ride Tours are the answer to replace the (original?) tires on my recently purchased lightly used 30-year old vintage Trek 7000 which I bought as a neighborhood rider to keep at my daughter's house to ride with the grandkids. The price was right and the product description hits the mark. Eight thumbs up.
Just purchased these in April - 2nd set on my Trek Emonda SL6 w Aeolus 5s - I purchased the reflective tires this round - they are awesome at making you even more visible & my first ride out, I picked up a carpenter's finishing staple. No tube puncture or anything! I highly recommend these. I'll probably upgrade to the 5000s on the next round.
