Even after trying multiple tires, if I had to pick a tire that fundamentally has good performance and can be used flawlessly in various aspects, there's nothing quite like the Continental 5000s—this is something anyone who has used them would easily agree with. However, the most disappointing aspect of Continental is the domestic price, which is so unreasonable that it's hard to justify—that's the first reason. The second reason is the finishing, which feels disappointing when you consider the price.

By finishing disappointment, I mean that while the weight is relatively uniform, when you mount the tire, even though the bead is clearly seated, the roundness is not uniform or there's wobbling side-to-side in many units.

During actual riding, this doesn't cause major problems, but if the clearance is tight, interference can occur with parts like the chainstay.

As alternatives at similar performance levels, the Michelin Power Cup or Schwalbe Pro One are options to consider. In the case of Michelin, at around 80,000 won, the performance is quite acceptable and nothing to complain about.

The volume is generous with very large actual measurements, so it's fine to operate at low tire pressure, and it's a model I recommend to others.

With Schwalbe, because I've experienced inconsistent quality, it's attractive when you only think about the price, but for some reason I don't reach for it much.

The Hutchinson Blackbird Maratread 3.0 is not a particularly preferred brand in our country, but I used the Fusion series before with good memories, and at the cheap price of around 70,000 won, when I saw reviews on BikeRollingResistance that puncture prevention performance and grip were decent, I decided to try it.

With the new Blackbird Race model, it's lighter and performance is said to be on par with Continental, so I considered using it, but the price doesn't differ much from Continental and the mileage is definitely shorter, so I thought it would be better to just use Continental.

The older Maratread 3.0, according to what the manufacturer says, lasts about 4,000 kilometers and the Race performs slightly better, but there's not much difference, so from a price perspective, the older model has clear merit.

The bike I ride is a Wilier Zero SLR, and the official spec is up to 28c, but since tire size varies by brand, I took into account the largest size that appeared from any brand and decided to buy 30c thinking I could use it up to that size without issues.

The spec weight is 310 grams and the actual measured weight is 307 grams, so there wasn't much difference. The tire mounting was surprisingly easy.

I mounted it with my hands without using tire levers, and there was no difference at all from a regular clincher.

When set on a 24mm internal width rim, the Continental 28c measured 30.5mm at 60 psi, and the Blackbird 30c actually came out smaller at around 30.3mm width.

The left-right deviation and roundness were very good.

Sometimes tires expand when left alone for a while, so I let it sit for a few days, but there was almost no change.

The height from the rim edge to the middle of the tread was about 25.3 for Continental and 25.5-6 for Hutchinson, with almost no difference.

Continental has about 500 kilometers of mileage and Hutchinson less than 100, so it seems they might be practically the same size.

With the air completely let out, I pumped 20 times with my floor pump and the pressure measured on the gauge was almost identical.

Looking only at size, I concluded that the Hutchinson Blackbird 30c is completely identical to the Continental 5000S 28c.

In terms of performance, I'm not skilled enough to push tires to their limits, and I'm just a normal neighborhood guy on a bike who rides at about 260 watts FTP with people around the neighborhood at a moderate pace for fun, so it's laughable for me to say which is better, but from what I've felt in comparison, on flat roads there's definitely slightly more resistance than Continental, so Continental definitely has better rolling resistance.

That said, the rolling resistance isn't that large. I think you can compare the feel to the Power Cup, and Continental is just such a good tire.

On the Rolling Resistance website, the Blackbird 28c shows about 13.3 watts, but I suspect the actual measurement is smaller, so when set at the same pressure, the degree of compression might be larger, which could have some effect on the results.

In the field, I could definitely feel the elasticity and smoothness of a top-tier tire, and the casing seems softer, with a feeling of smoothly reading the road surface, so there's a sense of stability in cornering, which is psychologically reassuring.

Usually you can feel that kind of feeling in lightweight racing tires, and compared to Continental, it seems somewhat softer.

The ride quality is quite decent.

In conclusion, in terms of performance it seems somewhat lacking compared to Continental, but if you're stressed about tubeless setup, I can recommend it because mounting is so easy. It's only two, so it's careful to say, but the quality consistency seems better than Continental and Schwalbe.

If you're definitely looking for a tubeless tire with decent performance in the 70,000 won price range, it seems worth cautiously recommending.

If you want the best performance even if it's expensive and don't want stress, Continental is the easiest answer, but you can buy a whole bike's worth of tires for the price of one pair of Continental, so the value for money (?) is exceptional.

Since this is a tire with very small actual measurements, if you've been using Continental, I recommend going up one size.
