Timekeeper
Lightning-Fast Road Tire
The Timekeeper is our premier road racing tire.

With lightning-fast straight-line speed and confidence-inspiring cornering, the Timekeeper can help you set your next segment PR and climb the ranks of the weeknight crit. This tire combines 120 TPI fabric with a lighter, more supple, and more puncture resistant Nylon105 belt to provide a faster, more supple, and puncture resistant tube type construction.

Purchased them to ride on the trails, they are pretty bumpy. I used the 700x23 version of this tire so tried the 700x28 and great, they roll perfectly and feel safer on bumpy roads and a bit off road.

I’m running 30c tires tubeless on some spinergy fcc32 wheels I rotate these every 1000 or so miles . no flats during this time tires roll really nice feel like a conti 5000. The price makes these easy to try. Good side wall feel. I am about 210 lbs and I am running these typically at 65-70 psi.

Nice price, but if available will be much more expensive in the future. However, mounting on the rim is a major hassle. Extremely tight. Will need tire irons to mount! Recommend using tubeless tape as Velox, being thicker, makes install very difficult.

Over the years, I've bought a number of these tires and will buy more as needed. Nicely made and run very true on the rim, no side to side warble, run straight, sit evenly in the rim hooks. I like the ride. I'm using the 25mm tire on older more narrow rims and they measure out about 23mm on these rims, as would be expected.

Some mid-level vittouria came on this bike. I wanted slightly wider so replaced with these. Aside from size bump, this feels like much better tire. My corner grip is considerably better (even when taking size into account...). They seem to roll far better (again, beyond what I expected with the size change) and are faster (both feel AND numbers I see on my bike computer as I'm riding). On my other bike I have Contintental Grand Sport Race, which i love. These actually feel a little better to me! I'm a convert. Love these tires."Puncture resistance" is a tough one to rate... really depends on where you ride and what manner of shrapnel is laying about your roads. I into the countryside but have to go through some "rural suburbs" to get there. So while I'm not dealing with the kind of stuff you'd find in the city, not remote and clean roads either - seems like many folks in the country near where i live seem to just throw stuff indiscriminately "out there" and assume it's gone. No punctures so far with a few hundred miles and a few months of use. They are wearing well - no issues with contact area or sidewalls.I did not find them particularly difficult to mount. I have come to suspect sometimes a "tough mount" has to do with particular lot/run of tire and particular wheel as I've had experiences that vary widely from on contradict some reviews in regard to "tough mounts." These took a tad more effort than getting my last set of continentals on ... but years ago I had a set of contis that made me insane... These were "in the pack" RE mounting. Stems seem fine, one valve looks a little bit wonky, like slightly bent, but it may just be a one-off; it works okay.These seem to punch far above their cost to me, making them not only a very good tire, but a great value. I'll be back to this brand next time I need/want tires.

I bought this for the price and my past experience with American Classic products and was not disappointed. A bit heave but that a tubeless design thing. Tight and hard to fit I recommend one of them new bead hook tools because tire leaver really put up a fight and can break. Tires run absolutely true on rim beads lock in well. Rolling a little sluggish only a few watts but hold their speed well. I will say this tire is bomb proof and can take a lot of abuse from bad roads rocks and even off road. Tire ware is normal with the flat spot forming on the rear so will have to rotate. overall great value for $45 bucks compared to tires nearly a hondo a piece. So yeah save your money by getting a pair of American Classics.

Purchased 700x28 C which looks like 25 C after installation.While replacing, it was a bit tight towards the end.However it's been without a puncture and crossed 4000 plus KM in 15 months.Overall happy with the buy.

転がりは軽くモチモチとした走り心地のタイヤです。グリップも良いですがウェットは少し苦手かもしれません。

タイヤは柔らかくて簡単に装着できます。少しモチっとしたグリップですが、Vittoria コルサシリーズ、GOOD YEAR EagleF1よりも軽く走れるので快適です。そこそこ軽くて柔らかいので、寿命は短いと思います。荒れた路面でも某ゴ◯ンプリ5000みたいに跳ねることもないので快適です。個人的にはゴ◯ンプリや鯵リストよりも良いタイヤなのに知られていないのが不思議です。

CHEAP BUT NOT A GOOD DEAL. Pros: they mount easy peasy, they are "ok" for puncture protection, ride is fine. CONS! They "sweat" sealant under 75+ psi no biggy but unsettling to see your tire oozing sealant like sweat. THE BIGGEST THING that sux 408 miles and I have to change out my rear tire...basically no tread on these brand new. Doubt I'll buy these again since they are cheaper but you go thru rear tires 2x-3x as often...so in the end you just spend a lot of time changing out these tires instead of riding.

タイヤのイメージは無い用品ブランドアメリカンクラシックのタイヤですね。 ロードのTLRは高級ラインばっかりですがこちらはミドルレンジの価格帯におりてきた感じですね。 海外通販で買うくらいの値段で国内アマゾンからすぐ送られてくる。 商品名が25，28，30ってなってるけど選択が無いですがこちらは30Cです（商品型番欄で70025とか70028とか表示されてるので700/25Cや700/28Cと確認） まずタイヤとしては珍しい細長いパッケージじゃ無く正方形に近い箱で、畳んだって言うより巻いた様な状態で入ってます。 紙箱に入ってるだけなのにかなりの重量あり、箱から出してもやっぱり重い。 ビード部がかなり太く、全体的な厚みもあり、サイドとセンターで段差有りでセンター更に厚くなってるけど1ミリに満たない差。 センター側と言っても車体を相当倒しても接地面になる広い範囲で、当たらないサイドが少し薄くなってる感じの作り。 全体的に厚い広がり癖になっているのでロードTLRとしては非常に上げやすいです（柔らかく軽いロードTLRはリムフックに自分から当たろうとしないけど、これは最初から当たろうとする広がりがあるので） 大抵のロードTLRはブースターポンプ必須だけど、これはビードクリーム使うとノーマルポンプですんなりアップ。 厚みがあるおかげでエア保持良好、シーラント無しでもちょっと走るくらい大丈夫なレベル。 定番Stansシーラントを入れて一晩で圧下がりほぼ無し。 なお、某メーカー同様に上限圧力のみの表示で最低圧力表示無いので乗って具合合わせです。 タイヤはほぼ完全スリックで写真でトレッドに見えるのもほぼプリント。 転がりは悪くないけど値段なりのミドルタイヤという感じ、グリップもドライなら悪くない感じで、コーナーでもブレーキングでも悪くないグリップをします。 全体的にはロードのトレーニングや普段使い等で比較的安価にTLRの心地よさを実現し、上げやすさやエア保持などもそういった扱いやすい方向に振られている感じ。 パフォーマンス追求では無く、扱いやすさとコスパを重視すると☆5という感じです。

Ordered these a few months ago and finally got around to mounting them up. Light weight, easy to mount, inflated nicely with just a floor pump, which isn’t always the case for tubeless. Once inflated to 70psi, noticed what look like little blisters in the tread. Not good, definitely a blowout waiting to happen. Now that I know where they are, I can see them even with the tires deflated. Very disappointed, I really wanted to like these tires and have always had good experience with AC wheels in the past. Maybe these were from an early batch and they have worked out the kinks in manufacturing, but I’m not going to drop another $75 to find out. Too bad I waited so long to mount them, now I can’t return them to Amazon.
