Worked Perfectly for Chain Replacement
These bike chain repair tools worked exactly as needed. I used them to resize a new chain and then install it on the bike, and the whole process was smooth and straightforward. The tools feel sturdy and easy to handle, which made removing links and reconnecting the chain simple. Great addition to any basic bike repair kit. If you’re doing your own maintenance, these tools make the job much easier. Definitely a solid purchase!

Great little bike chain kit.
This is a perfect little bike kit that I got my boyfriend because he’s always repairing our bikes or working on his battery powered go-kart. He says it’s good quality, works well, and includes all the requisite tools included for repairing chains. It’s small enough to easily fit in his backpack without taking up too much space, but it’s sturdy and doesn’t bend or break with normal use. The chain-breaker, specifically, works well. I’ll probably eventually buy another one for my personal use.

Quality & Necessary Recumbent Tools
Was installing an Efneo front drive on a recumbent trike and needed more than a low-profile chain breaker. While I do EDC a Victorinox Spirit X (purchased last year from Amazon) had figured perhaps I should also get master link pliers too, So while searching on Amazon I found this Oumers kit that also included a much desired chain wear tool too. Was expecting to pay $30 alone for a quality chain breaker, but got a great deal as a package. And I did compare with other items on Amazon, and also offline reviews before making a selection. Used the Oumers chain breaker on some KMC X8.99 chain I also purchased with this kit. The links were a bit more stubborn, so I found that using a leather glove to get the initial hard press the rest was easy. What I do like about the Oumers chain breaker is that the shelf has an adjuster to fit the chain, something other chain breakers don't do. And this tool came with an extra bit, which was an added plus! And a wire to keep the chain ends from slipping away. (grin) Use extra wire as a backup if you've not done this before, or if you have a 'helpful' friend. (grin) So for breaking the breaker is fully adjustable, aligns near perfectly - does not angle off, and the press works great. Did not have any issues with the Oumers chain breaker or the rest of the tools. Which is a BIG PLUS for me, as stuff does not always go as planned. No worries here! Oumers chain wear tool showed me there was still life in the previous KMC X72 which had roughly 3,000 miles on it pulling near maximum load (475#). That is impressive for an inexpensive chain. This time around I went with a chain with more plating as I ride in any condition. And for those pliers. Oh how may times I used those pliers! They were better than the Spirit X and was adding and removing the Missing Links that came with the KMC chain. While I do want to put the chain together the proper way, without using the master links, I need a bit more practice. And I have an older chain (that is still usable) to practice with using these Oumers bicycle tools. If you are on a budget and need a quality kit that works, no gimmicks, and gets you done and down the road, get this Oumers kit. Even if you do not use the chain measuring tool right away, it is still worth the extra few bucks because you will be needing one later on. Bonza tools!

all good except the chain checker
Pliers and chain breaker worked well. the chain checker is weird, 1% goes in more then .75% side which does not make sense. good value otherwise.

Excellent bike tools for keeping your bike in shape
This kit had everything (and more!) that I needed to service and replace chains on my bikes. I don't use them often, so it made no sense to buy Park. This get the job done!

This has everything you need to shorten a chain, set master links and even a gauge
Great tools set! This has everything you need to shorten a chain, set master links and even a gauge to see how worn your chain is. I used this to put a chain on my 80's Roadmaster bicycle. Durable enough for bicycles but haven't tried it on the larger 530 motorcycle chain my Harley has. I'll update when I use it for tat application. A good buy for a complete tool set.

Works well
Worked fine. I was able to remove multiple pins from the chain of a children's bicycle. Worked well for the price.

Kit completo e facile da usare, mi ha permesso di rimettere in funzione una bici ferma da anni
Ho utilizzato questo kit di riparazione per bici per rimettere in funzione una vecchia bicicletta che era rimasta inutilizzata per diversi anni. Non avendo grande esperienza nella manutenzione delle biciclette, cercavo un set semplice da usare ma sufficientemente completo per intervenire sulla catena e riportare la bici a uno stato funzionante. Contenuto del kit e prime impressioni Il kit si presenta ben organizzato e include gli strumenti principali per lavorare sulla catena: attrezzo smaglia-catena, pinza per maglie rapide e calibro per verificare l’usura della catena. È un set essenziale ma completo per le operazioni più comuni legate alla manutenzione della trasmissione. Gli attrezzi danno una buona sensazione di solidità e risultano facili da impugnare, anche per chi non ha molta pratica con questo tipo di lavori. Esperienza d’uso su una bici ferma da anni Nel mio caso ho utilizzato il kit per sistemare una bicicletta che era rimasta inutilizzata per molto tempo. La catena risultava sporca, usurata e non più scorrevole. Grazie al calibro ho potuto verificare lo stato della catena e capire che necessitava di intervento. Lo smaglia-catena si è rivelato uno strumento molto utile per rimuovere e regolare la catena, mentre la pinza per maglie rapide ha semplificato notevolmente le operazioni di apertura e chiusura. Anche senza esperienza specifica, sono riuscito a eseguire le operazioni con calma e attenzione, riportando la bici a uno stato funzionante. Per me è stato particolarmente soddisfacente riuscire a rimettere a nuovo una bicicletta che sembrava ormai inutilizzabile. Facilità d’uso e adatto ai principianti Uno degli aspetti che ho apprezzato di più è la facilità d’uso degli strumenti. Anche un inesperto come me è riuscito a comprendere abbastanza velocemente come utilizzarli. Naturalmente è sempre utile consultare qualche guida o video per imparare le basi, ma il kit in sé è intuitivo e non richiede attrezzature aggiuntive. Versatilità e utilizzo nel tempo Questo kit non è utile solo per una singola riparazione: può essere utilizzato periodicamente per controllare l’usura della catena e intervenire quando necessario. È quindi un investimento utile per chi vuole mantenere la propria bici in buone condizioni senza dover ricorrere ogni volta a un’officina. Conclusioni Nel complesso considero questo kit un buon prodotto, pratico e funzionale, adatto sia a chi ha già esperienza sia a chi vuole iniziare a fare piccole manutenzioni in autonomia. Il fatto che anche un principiante come me sia riuscito a rimettere in funzione una bici ferma da anni è, a mio parere, la dimostrazione della sua utilità. Un set consigliato per chi desidera prendersi cura della propria bicicletta con strumenti semplici ma efficaci. Spero che la mia esperienza possa essere utile a chi sta valutando l'acquisto.

Super Set, nur so ist ein Kettenwechsel auch ein Kinderspiel
Ich habe mir dieses Set gekauft, um eine Kette bei meinem E-Bike zu wechseln. Zuerst mit der Zange die alte Kette am Kettenschloss geöffnet. Das klappte wunderbar. Dann die neue Kette mit dem Ketten-Nieter gekürzt. Auch hier keine Probleme. Ich habe das ganze zuvor zweimal vorsichtshalber getestet. Es funktionierte immer einwandfrei. Also dann auch an der richtigen Stelle der neuen Kette. Danach dann die Kette auf das Bike aufgezogen und mit dem beiliegenden Draht die Kette befestigt. Nun noch das Kettenschloss eingehängt und nachdem ich den Haltedraht entfernt hatte, das Kettenschloss mit der Zange verriegelt. Fertig. Ohne diese Werkzeuge ist ein Kettenwechsel eigentlich nicht möglich. Ich habe mich vorher durch ein Video informiert, wie Ich vorgehen muß und was ich alles benötige. Alles liegt diesem Set bei. Es hat alles so funktioniert wie es in dem Video gezeigt wurde. Wie lange das Set hält, kann ich natürlich nicht sagen, aber es ist nach diesem Aus- und Einbau nichts gebrochen oder verschlissen, sodass ich das Set bestimmt noch ein paar Mal verwenden kann. Ich finde das Set wirklich top 👍, kann es zu 100% empfehlen. Bei dem Preis macht man keinen Fehler. Viel Spaß beim Ketten wechseln 😉

ロードバイクのチェーン替えをこれだけで
ロードバイクのチェーン替えを本製品のみで行うことができました。 3点どれも品質は必要十分で一度の使用で壊れる気配は全くありませんでした。 末永く使いたいのであれば、メーカーものを購入したほうが長く利用できると思いますが、 そうそうチェーンなど交換する機会はないと思うので、安く済ませたいのであればこれで十分なのでオススメです。
