Great tool. Easy to use. Fits 12 speed chain. It looks durable compared the old one that I have that got bent while using it. It comes with a spare pin. Great buy. On time delivery.

This tool was fantastic. Chains have always been a challenge for me. With this tool they never will be again.

Oumer's Chain tool ---- I haven't used it extensively and I admit that I bought this tool without reading all the reviews. So, from my limited experience with this tool I feel that it does the job of removing chain pins easily and efficiently. As others mentioned there were no instructions with the tool but experience with other chain break tools kept me from making mistakes that resulted in bent chain supports and broken push pins. The hollow screw (opposite the pin) needs to be screwed in to support the chain while you are twisting the handle and applying pressure to push out the pin. The hollow end will catch the pin if it is removed completely.BTW - when putting chain back together purchase new replacement pins, Yes, you can save a few $$ by using the old pin. If you completely remove the pin it is tough to align the links/holes to get the old pin in correctly. It can be done but may cause the chain to bind or seize. Replacement pins have a long slightly smaller diameter section that you insert into the chain links. This section guides the slightly larger diameter chain link pin into the holes. When the link pin is fully inserted remove the chain from the tool and use a pliers to snap off the guide section of the pin. Search Amazon for Bike chain replacement pins - know the brand of chain, number of gears in your rear cassette, and make some measurements of the chain pin length and it's diameter. this link is an example: "Shimano 10-Speed Replacement Chain Pins"If, in the future, you want to remove your chain for cleaning etc use a replacement link similar to: "YDZN Bicycle Chain Link Connector, 11 Speed Quick Master Link Joint Clip (2 Pcs,Silver)" Park tool sells a "pliers" for use when installing and removing this type of link. Again, these links are not "generic" so you'll need to know the chain you are using the replacement link in. Use of these links make it easy to remove the chain for cleaning or repair.PROs -- fits my hand comfortably and the large handle is easy to twist. in and out. The hollow screw captures the pushed out pin and supports the chain while working on it. An extra pin included in the handle along with the wire chain hookCONs - as others mentioned it is a bit large to be carrying "just in case" you need a major chain overhaul while on the trail or road. It can stay in my tool box - it fits nicely in there.Question I have: looking at the assortment of chain tools on Amazon why are there so many tools that look just like the Oumer's tool but have different names. They are all in about the same price range.. Strange....... :-)I have not received any support or compensation from Oumer's or from any company selling replacement pins or replacement links. Why give it only 4 stars? I reserve 5 stars for something that really blows my socks off. This is a good tool and "I like it"If, after using this tool more I have information to add to this review I'll do that. Till then, enjoy your days on the trail.

Bought this for my son's mountain bike and it has come in handy! It is easy to use and gets the job done.

My trusty chain tool finally broke after 50 years. My search for a replacement led me to this tool. I used to own/operate a bike shop decades ago, so I am picky about my bike tools. Rather than using the quick link to connect chains, I like to punch out a pin most of the way and then then use the chain tool to put it back together. The chain hook allows me to re-spread the link out to loosen it. Otherwise it is very tight.My only complaint is that it is so small it can require quite a bit of force to operate on a tight link. My old hands are not as strong as they used to be. A small hollow tube extension solves that problem for now.

Easy to use and sturdy….def a requirement for anyone that does their own bike maintenance. 10/10 must have

I needed to shorten a new chain and wanted to try myself vs. taking my bike to a shop. This tool did the trick for me, but it wasn't all easy.I'm not an expert bike mechanic, so maybe I just need some practice, but a couple of key takeaways from my use (that may be me, may be the tool, or may just be the way it goes) ...- I saw enough videos that explained NOT to push the pin all the way out of the final outer link (to make it easier to push the pin back in again afterwards). Since you can't see the pin coming out, it was difficult to tell how far to keep turning. The first time, the pin came out completely. No complete obstacle in the end, it just made it harder to get the chain back together after removing the links.- I noticed after removing the first pin that the metal "guides" on the device had actually bent due to the force of driving the pin out. I was careful to try and center the pin pusher and so I don't believe I was ever just pushing the whole link, but I was surprised to see the metal bend. Luckily, that softness also meant it was easy to bend back using a flat head screwdriver, but overall I would expect this part of the device to be heat treated for strength vs. flexibility.- The (minimal) instructions show you how to break the chain, but not to re-join it. Again, the internet abounds with tutorials, but it was a little tricky (especially since I had to try and get the pin to hold in after it had come completely out in step 1!).It got the job done, and I think next time I would have a slightly easier time, but the softness of the metal and lack of instructions cause me to not give it a to rating.

This chain tool works fantastic. I need to use it one or two times a year. It does the job well and I keep it in my kit. It's not well finished, but it is also very inexpensive. It is however robustly built and works perfectly. I recommend it!

CN-HG40にアンプルタイプコネクティングピンを用いてチェーン長を短縮するために購入。リンクピンの取り外し、コネクティングピンの圧入のどちらも不具合なく行うことができました。アンプル部分を折り取るには、一度ハンドルがついていないほうのねじを外し、単独で使用することで対応できます。

ok

La premessa è più che doverosa: come ho già specificato in altre recensioni, non sono un ciclomeccanico e non faccio questo di professione. Sono un amante delle biciclette e mi piace metterle a posto e fare manutenzione. L’uso che ne faccio è esclusivamente casalingo, per me e per amici.Dopo quasi tre anni di utilizzo posso dirvi ufficialmente cosa ne penso.È un ottimo smagliacatena, resistente, robusto e pratico. Prima di acquistare questo ne avevo un altro, era quello classico tutto in acciaio, quello con il manico molto sottile, il più famoso in commercio. Dopo qualche anno di utilizzo si è spezzato il pernino e ho dovuto sostituirlo.Questo non mi ha dato ancora problemi e vi dirò che è decisamente più comodo dell’altro per diversi motivi:L’impugnatura è più grande, si riesce a lavorare più comodamente, la maniglia è rivestita in plastica, risulta meno scivolosa e fa indubbiamente più grip.È incluso il gancio per la catena, utile o forse meglio dire FONDAMENTALE se si vuole ri-magliare la catena dopo averla smagliata.Incluso nel manubrio c’è un perno di ricambio nel caso dovesse rompersi.Fantastico! Un attrezzo veramente comodo.Il venditore nella descrizione del prodotto dice che va bene per le catene da 7/8/9/10 velocità.Io sinceramente l’ho utilizzato su una bicicletta a 6v, una a 8v, due a 1v e un tandem a 1v.Non mi ha mai dato problemi.Ciò non toglie che quello che ho fatto sia potenzialmente sbagliato.Ha però un compromesso: essendo ingombrante occupa più spazio in caso di trasporto. Non essendo modulare (come quello famoso in acciaio) non si può smontare per riporlo in una falsa borraccia o in una borsetta.Per questo è adatto quasi esclusivamente per un uso da officina/garage/casalingo.Pagato 8,99 euro venduto da terzi e spedito con Amazon.Se avete ulteriori domande sul prodotto non esitate a contattarmi.

Easy to use. Quality is good.

Gerçekten harika ve çok sağlam.. Tavsiye ederim
