Right out of the box you can tell these are built to last. They were easy to assemble and fit all sizes of bikes with the ability to move the band to either of the rear cylinders. They feel smooth when riding and they work very well for indoor training when it’s too cold to ride outside.

As a long time cyclist who used to train indoors exclusively on a high end set of rollers during the off season, I can say that these are very good at this price. They are aren’t flimsy, they roll smoothly and it folds down well into a smartly sized package. I bought these because in times past this brand, which is made in Japan, tend to be well designed and well made. I am not disappointed thus far. My first ride on them revealed only one thing…I forgot how easy it is to fall over getting started. This is the real challenge to roller training, getting going. That said, after I had a good roaring laugh at myself for falling over thinking that won’t happen to me! Ha! It happens… I found nothing that made me regret my purchase.Moving on, these rollers simply work. They don’t seem to have much drag, the drums spin smoothly on their bearings with no noticeable wobble or runout, the frame doesn’t rattle or creak and the wheelbase adjustment handled my frame without troubles. Assembly was a breeze and the instructions were well made.Given I have only had them a very brief time, I can not say to the long term quality, but so far they are transparent. By that I mean they do what rollers are supposed to do…roll smoothly and efficiently.As a former Cat 1/2 racer, I can lend some helpful tips to get started. Tip 1, Starting in a couple gears higher than you think is better than lower. The faster you spin the drums, the better the gyroscopic effect kicks in and this helps you to get on the rollers. Tip 2, be loose on the bike. Your inclination is to over correct by being stiff and this makes it MUCH harder to get going through the first few seconds of getting the rpms up. Ride loose and relaxed with a light grip on the bars and breathe. Tip 3, if you feel like you are gonna ride off, don’t go crazy. If you ride off, the wheels come to a halt really quickly, but because you and the bike are stationary with out momentum, you wont go flying off into the room or wall. You will simply fall over. Tip 4, to make things harder, hit harder gears and ride faster. Yes, there is a limit to how much your resistance training is on rollers without a mag or fan unit, but roller training is not a focus for that aspect of riding, a smart trainer or even the weight room is better there. Rollers are for balance and technique and over all efficiency of riding smoothly and gracefully. If you watch pro’s race and compare the footage to racers in recreational events you will see dramatic differences in how smoothly a pro rides, they glide with almost effortless energy. Rollers help to train for those abilities. I can sweat just as much on rollers as I can on a smart trainer racing on Zwift. You gotta know how to use the trainer!. Last tip, take your time and learn as you get more comfortable. You won’t enjoy roller training if you get overly frustrated because you think you are a great rider and rollers should be easy. They are, but you don’t just ride rollers just like that. Ride them regularly, even if its 20 minutes a ride twice a week and over the coarse of the winter, your first spring ride will reward you with the efforts of your training with a smooth and efficient ride.In summary, rollers are a great training tool and if you are shopping for a set, this is an excellent budget trainer!Update, Feb 2024: nothing to report! They work as good as the day I bought them and they work just as good as the best rollers on the market. I added another star to reflect my longer term experience and feel these are an excellent value for a “budget” roller trainer.Another tip: Make sure you measure your wheelbase and set up the rollers exactly as specified in the manual. It makes a profound difference in the end result if you omit this step, it is critical.

Great training rollers and the price won’t bankrupt you. They assembled easily but pay close attention to the instructions and take your time. They’re easy to get mounted on, not loud or excessively resonating like some rollers I’ve owned in the past (the wife appreciates this). Nice and smooth, easy on the ears and I couldn’t have asked for better.

Good

Well build with nice quality. Made in Japan! Cons too loud for apartment but good for garage usage

I bought this one recently. I just started bike training to prepare for a biking trip in this summer. I purchased Garmin Trecx roller as well, and want to know which one is better. This one is all made by aluminum. It can also be converted to a stationary training system, by taking off the front wheel . But that needs an additional part which didn’t come with my purchase. It is very similar with the garmin one, and a bit heavier. This box is shipped from Japan in 3 days, very fast. The manual is very detailed, in Japanese though, but OK to use Google translate to follow. Installation is easy. No noise while riding on it. And I like the attached footstep to get on the bike.

This is nice to use when you want to ride your bike inside. It's quiet and easy to use. I've had it for almost 2 years and I haven't had any issues with it.

I originally ordered the RockBros rollers which were terrible. So I figured I’d spend an extra hundred dollars and buy these. IT IS THE EXACT SAME PRODUCT! They just put their logo on it and added $100 to the price tag!Also, they gave me two right side pieces of the frame, so I couldn’t even put them together if I wanted to.Also, the rubber band they gave me was broken.

長年使用していた、古いミノウラローラー（ローラーが太くて、ごっつい）を手放しました。それと比べればかなり静かで、小さくなった感じで良いです。説明書通りで問題ありませんでしたが、作業前に一通り目を通しておくことが必要だと思います。前輪ガードを付けるかどうかがポイントです。踏み台は一通り組み立て後に付けられます。前輪ローラーの位置変更は、全て解体しなくてもなんとか変えられますが、自己責任で。結果、良いものかと思います。

レビューでは組み立てが面倒だとのレビューもありましたが、特に問題なく組み立て使用できました。他社の３番ローラーからの買い替えですがミノウラブランドに憧れて買い替えました。凄く気に入っており、コストパフォーマンスもいいと思います。大事に使わせてもらいます。

Got the wife's seal of approval. Within minutes of finishing my first ride on these rollers, the wife praised how quite they were compared to my old Minoura Moz rollers. The textured black finish on the rollers eliminated all wheel squeaking and the bearings were very quiet. Assembly was pretty easy too. It took only 30 minutes to put it all together and get it adjusted to my bike size. The R730R is a great set of rollers. I can easily recommend this product.

説明書に沿って組み立てる前に、まずは自分の自転車のホイールベース（前輪軸と後輪軸の距離）を測って、前ローラーと後ろローラーの位置ぎめを行う必要があります。これを怠ると、組み立てた後に、バラして再度組み立てることになる可能性が大きいです。バラすのも組み立てるのも難しくはないですが、ボルトを外したり締めたりかなり面倒です。取扱説明書によると、初心者の場合は、バイクの前輪軸の鉛直線が前ローラー軸鉛直線から10mm-15mm後ろにするべきとあります。この製品は、前ローラーでホイールベースを970/1000/1030/1060/1090（30mm刻み）で変更できます。後ろローラーは2本のうち後ろの1本を後(0mm)か前(-20mm)のどちらかを選択できます。初心者向け設定をおこなうとき、前ローラーと後ろローラーの位置で以下の範囲のホイールベースをサポートします。単位は全てmmです。＜前ローラー970/後ローラー　0（後）＞ホイールベース最小 955ホイールベース最大 960＜前ローラー970/後ローラー　-20（前）＞ホイールベース最小 935ホイールベース最大 940＜前ローラー1000/後ローラー　0（後）＞ホイールベース最小 985ホイールベース最大 990＜前ローラー1000/後ローラー　-20（前）＞ホイールベース最小 965ホイールベース最大 970＜前ローラー1030/後ローラー　0（後）＞ホイールベース最小 1015ホイールベース最大 1020＜前ローラー1030/後ローラー　-20（前）＞ホイールベース最小 995mmホイールベース最大 1000mm＜前ローラー1060/後ローラー　0（後）＞ホイールベース最小 1045mmホイールベース最大 1050mm＜前ローラー1060/後ローラー　-20（前）＞ホイールベース最小 1025mmホイールベース最大 1030mm＜前ローラー1090/後ローラー　0（後）＞ホイールベース最小 1075ホイールベース最大 1080＜前ローラー1090/後ローラー　-20（前）＞ホイールベース最小 1055ホイールベース最大 1060この程度の情報を組み立ての説明書に記述するべきです。説明書の改善が必要と思われます。さらに、私のバイクのホイールベースは980mmなので、何ということでしょう、初心者設定範囲外です。仕方ないので、一番近い組み合わせで使用するしかなさそうです。このことに気がつくのにだいぶ時間を費やしました。今日はもう疲れたので明日組み直します。なので、実際に使用したレビューはまだできません。上記の通り説明書の不備等により星はつけられません。＜追記＞実際に使用しました。音もそれほどひどくなく、今のところ特に問題なく使えているので、星4つ。
