Hutchinson New 2018 Fusion 5 Galactik Tubeless and Tubeless Ready Bike Tire with The New ElevenSTORM Compound

The good: these are great race tires, they are fast and grippy.The bad: The front tire flatted twice, once in the first 100 miles, and then again about 500 miles later. I had to run it with a tube because Stan's sealant couldn't get it to stop leaking where it flatted (puncture about 1mm wide).The rear tire held up great, didnt lose much air over time, and it went on easy just like the front tire when I mounted them.So 3 stars for the front tire and 5 stars for the rear tire gives an average of 4 stars, seems about right.

I installed these with no problems with Stan's sealer upto 70psi. I took a 40mile test ride, which was fantastic. However, a few days later, I noticed sealant leaking out of multiple pinholes at the mold injection sites of one of the tires. The other (rear) tire seemed fine, so I assume this is a defective tire. However, I would expect better quality assurance and testing for such a well known brand. The pressure held mostly (down to 50psi now) but my bigger concern is if this will rip open like a zip-loc bag during a ride. I did write the company, so we'll see how they respond. Nonetheless, a one star for poor quality.

Son buenas

今までコンチネンタルとiRCのチューブレスを使用した事が有ります。それらのタイヤは最後の部分レバー無しでは入りませんでしたが、このタイヤは手で簡単に嵌められました。取付１０分、フロビードアポンプでエアー抜けする事なく2分でビード上がりました。チューブに空気入れる感覚と同じでした。もし出先でパンクしても簡単に外れますので修理に対する安心感が有ります。オーダーしてから届くまで時間がかかったのでその点はマイナスですね。

TLRなのでシーラントが必要になるが、それでも240g前後と軽くグリップ力も良い。タイヤも嵌めやすくてビードもあげやすいので性能はとても良い。ギャラクティックは決戦用的な位置づけにあるタイヤなので寿命が短いことが欠点かもしれない。使って後悔しないタイヤだと思います。個人的にこのタイヤが一番良い。
