Familiarity: I've put it through the wringer

These are my go to tires when the roads are covered in salt and cinders during the winter. Over thousands of miles ridden (on several sets) I have had one flat due to a sharp piece of glass. The only other bad occurrence was losing the rubber down to the puncture belt after hard braking on an older tire. These tires are just as puncture resistant as Gatorskins, but they don't last quite as long. They have great grip in the wet. They have lower rolling resistance than Gatorskins, but are still nowhere near summer race tires. When the going gets extra tough I recommend these.

Familiarity: I've put it through the wringer

I have put thousands of miles on these bad boys this past Fall and Winter and I am pretty impressed. Tire wear is very good, I'm able to get 2500 miles off a set (I do rotate them at ~1000 miles). They are also pretty puncture resistant, no cuts on cinders so far (just three pinch flats). Rolling resistance is okay, better than my heavy duty Continental 4seasons but they definitely don't feel as supple or fast as my Schwalbe Ones. They offer a pretty good middle zone between durability, puncture resistance, rolling resistance, and price that make them great training tires.

The one disappointing thing about these tires is that they do not grip very well in the wet... Compared to aforementioned Contis or Schwalbes I feel more slippage and less confidence once the roads get wet. I would not recommend these tires for all out descending. Despite this weakness these are still good training tires if you can get them at a good price. Just be careful in the turns!

QC issues, good performance otherwise
3 5

Familiarity: I've put it through the wringer

*Edit* So I have ended up getting the rear wheel rebuilt with new spokes and nipples because it kept slowly losing spoke tension over time... My local shop and Mercury both suggested that the spokes were likely not prepped correctly when first built. To fix the problem Mercury suggested putting blue loctite on the spokes, but my local shop said that would likely permanently freeze the spokes in the aluminum nipples and cause truing problems down the line. One rebuild and $150 later with slightly different spoke specs I hope the problem is solved. I still think these are good, stiff wheels for the price that likely add an aero benefit, but I am dismayed at the quality control lapse.

The stock brake pads are terrible. I have switched to Swissstop Black Prince pads with quieter, smoother braking.
FYI: Buying the pads through Mercury's site is a rip off, just search for equinox or gigantex brake pads online to find way better deals.

If your budget is tight I'd recommend these, but if you can manage to invest a little more I'd recommend something higher quality with better hubs like the November Rail.

*Original*

This is my first set of full carbon clinchers, so keep that in mind when reading this review. I got my set of Mercury M5s off this site on sale for $1000. After 1800 miles and a successful Spring racing season, I definitely feel like I have gotten my money's worth. These wheels are noticeably stiffer/less flexy than my 1550g aluminum clinchers (both my Rol Race SLs and my American Classic Victory 30 tubeless). This is very important to me as a 170+ lbs sprinter, because I am able to flex a lot of wheels and I find it annoying. I also feel like these wheel hold speed better than my 30mm aluminum clinchers, although I don't have a wind tunnel to verify it. As far as cross wind susceptibility is concerned these do get pushed lightly in the wind, but the feel is similar to my dad's HED Jet 6 FR wheelset (which is supposed to be pretty good in that regard). Many of the smaller riders I know prefer 35-48mm wheels because it is harder for them to control deep wheels, while I see a greater percentage of larger riders on deeper wheels.

I have had some issues with the wheels, and if I did not get them for so cheap (relative to other carbon clinchers) I may have given then a lower rating. First of all, I had to get the wheelset re-tensioned after delivery because it kept coming out of true. It's annoying that wasn't caught in the factory. Second, the stock brake pads squeal and tend to wear down quickly. All in all I am satisfied with the wheelset and performance, especially considering the price.

The best racing tire
4 5

Familiarity: I've put it through the wringer

*Edit* Still my go to race tire. One weakness: they unclinch much easier than other tires. I have almost wrecked in two races only to pinch flat moments later because the tire has come unclinched. However, barring disaster these have good puncture resistance and grip and low rolling resistance so I'm still using them.

Without a doubt, these are the best racing tires I have used. I have put 1600 miles on my current pair of 25mm Schwalbe Ones without a single flat. This is incredible considering that it includes riding and racing in March and April when the Ohio roads were still covered in cinders and salt from all the snow. I am guessing that I will be able to squeeze 2000 miles out of my first pair, which is a lot more miles than I can usually get out of a non endurance/training tire. The tire rides phenomenally, with low rolling resistance, good road "feel," and great traction/cornering in the wet or dry. My previous go to tire was the 4000s, but I ended up buying these tires because I had 4 different 4000s II tires (won or purchased at different times both 23 and 25mm) fail on me with sidewall cuts (the tube would stick out of the hole). This tire rides just as well as the 4000s with much better flat protection. The flat protection is good enough that I trust this tire to train and race on in early Spring, whereas, in the past I would keep running my winter 4seasons tires until May because of flats from cinders (small, sharp rocks put down on country roads to increase grip in the snow). This is the best all around tire I have ever used. I plan to use it in all but the dead of winter. In winter I switch back to conti 4seasons for even more flat and sidewall protection at the price of much higher rolling resistance.

So many side wall failures
2 5

Familiarity: I've put it through the wringer

The 4000s was my go to racing tire in the past. It rolled well and had adequate flat protection. The 4000s II has been nothing but a disappointment. I have had 4 of these tires fail due to cuts in the sidewall that ruin the tire. I am not sure what changed, but the lack of reliability of this tire compared to the original is appalling. Other people I ride with have been experiencing the same problems. The only positive for this situation is that I have discovered the Schwalbe One, which rolls very well and has had phenomenal flat protection for a racing tire. 0 flats in 1600 miles of gravel and cinder covered Ohio roads, including during early Spring when the roads were frequently being treated for snow. The 4000s II rides well while intact, but so does the One. Note the tube popping through the hole in the photo. That happened last Fall, before there was a lot of crap on the roads.
