Topeak D2 SmartGauge

Excellent

This product is really wonderful, as it meets both types of requirement for the user of Bicycle, easy to carry and use in all weather conditions, indeed, an accurate & compact device.

I love using this. It's so convenient, easy and useful to have. I have three bicycles (with three different types of valves - Presta, Schrader, Dunlop), one motorcycle and a car. This fits them all. Literally one size fits all. Once while riding my road bicycle I had to repair a puncture on the road and fill up the tube using a small pump. I didn't have any gauge to check. Upon arrival I checked the pressure on the gauge attached to my floor pump. It was 20 psi. Dangerously low for a road bike. I could've easily got another puncture before reaching home. That's when I decided to always carry a pressure gauge during my road biking trip. The puncture repair kit is incomplete without this. This solution from Topeak solved the problem of having to keep two different types of gauges for two different valves (Dunlop and Schrader are similar from a gauging or filling nozzle point of view and are considered as one, Presta being the other). I would've preferred a small pouch to put it in. I wouldn't put it naked inside my saddle bag which has other hardware that can potentially scratch this little beauty. I have asked my daughter to stitch a small cloth pouch for it. A screen light would make it perfect but perhaps push the price up. Disclaimer - I didn't buy it from amazon.in. Someone brought it for me from the US.

Ottimo prodotto!! Usato sia per mtb. E bici da corsa. La lettura risulta essere precisa e affidabile grazie anche a l’ampio display lcd, Che ne facilità l’utilizzo. La pressione può essere letta in bar ma anche in psi, Tramite la pressione di un apposito tasto. Molto comoda la funzione che permette di monitorare in tempo reale, L’esatta pressione Della gomma, mediante la pressione di un tastino giallo Che sgonfia la gomma a step di 0,1 bar, permettendoci di raggiungere, L’esatta pressione desiderata. Tramite un apposito tasto a scorrimento, posto sulla testa del misuratore, È possibile inoltre selezionare il tipo di valvola, presta o schrader. Molto comoda inoltre la funzione, che permette di ruotare la testa del misuratore, Per meglio adattarla alla nostra gomma. Che dire, ottimo prodotto, affidabile, preciso, Consigliato a chi come me, voglia avere sempre a portata di mano, Un accessorio per le nostre bike, preciso e indispensabile, Durante le nostre uscite. Un ringraziamento ad Amazon, per la sua solita, ed ottima Gestione della spedizione, e comunicazione sul prodotto.

微妙な空気圧調整が手軽にできるのはありがたいです。とりわけロードはチューブレス化によって空気圧の要求がシビアになりました。barでもPSIでも測定でき、出発前に調整することで、ロードの乗り心地とパフォーマンスが格段に向上しました。MTBでトレイルを走った経験は少ないのですが、高圧のままトレイルを下ると、バランスが取りづらく転倒しやすくなります。 このエアゲージは操作がシンプルで扱いやすいです。スポーツバイクに乗るなら、絶対持っておくべき機材だと断言できます。

The price is little high

Will easily inflate my road bike tyres several times, great product

It's small and probable. A great feature I love about it - it can release the air from your tires (if the pressure is too high) and it will show real time pressure thus you will get the desired pressure for your ride.
