SHIMANO HG40 116 W/CL Chain - Grey, 6/7/8 Speed

Perfect chain for my 7-speed bike! The chain length is also good. The included chainring is useless. Not expensive and good quality. Original Shimano chain. Sorry no picture.

Exactly as needed, no issues

Good quality, but the link used to connect the chain was really difficult to fit. Hence the 4 stars.

Good quality heavy chain. Unbreakable.

It fits onto my Carrera Vengence 3x8 only problem is that the pinned link it a fractionly bent. Had to bend it slightly to fit with the link closer.

Good quality

Excellent value for money Fast delivery

I fitted 2 of these to my 7 speed Shimano equipped mountain bike in spring 2021. The first lasted for less than 1000 miles. The second lasted for 400 miles and stretched so rapidly that I changed it because I could not bear the noise of it running roughly on the sprockets whose rate of wear was much slower than the rate of stretch of the chain. Terrible! Each new chain was fitted at the same time as a new Shimano cassette, so each stretched chain actually cost me £25-30 in parts (the cassettes showed severe signs of wear - the second chain had over 2% extension when I changed it). I should add that each chain was thoroughly lubricated with Mucoff chain lube daily before my ride of typically 40 miles, and I only rode in fine weather. I discovered that the original chain on my Shimano equipped Trek MTB was a KMC Z7 and this had lasted for about 10,000 miles. Although I still have some spare Shimano chains, I fitted a new KMC chain (again with a new Shimano cassette but still running on the old chain wheels so it would be a fair comparison) and it ran well and quietly for 3000 miles and I have just replaced it as it had over 1% stretch and was beginning to slip during gear changes, probably due to the chainring wear caused by the Shimano chains stretching. I will never fit one of these Shimano chains to my bike again. I will now continue to use the KMC Z7 product. They also have a much easier (for my old hands) joining link which can be undone and reused. This is not a positive review at all - but I wrote it so people won't waste their money on a product you would expect to be good (given the brand name) but isn't, and maybe Shimano will take note too! It worked, but due to its rapid wear it's lifetime was too short and in stretching so fast it damaged my cassette and chain wheels which have had to be replaced too at considerable expense.

Excellent ,smooth shifting on my seven speed freewheel.Deligted switching from a 53 years old still usable chain. The link was tricky to install but a few videos got me straighten up. Comes with instructions.

all good, all I need for my bike

So far so good. Packaging looks like the real thing and the price is good.

I prodotti Shimano sono sempre una garanzia e nei miei circa 100.000km di viaggi in giro per l'europa e per il mondo ho sempre fatto riferimento a questo marchio: nessuna sorpresa, grande compatibilità tra modelli diversi dello stesso marchio, robustezza e affidabilità, relativa semplicità di riparazione e/o sostituzione. Personalmente preferisco le trasmissioni 3x, piuttosto che 2x o 1x, semplicemente per la varietà di rapporti applicabili alle diverse condizioni di carico bagaglio delle me biciclette ma, soprattutto, per la ridotta usura delle componenti quando la linea catena è pressoché sempre rispettata. Va da sé che nulla sia indistruttibile, ma una periodica ragionata regolare manutenzione, anche in viaggo, minimizza gli imprevisti e da accesso precoce ai danni da usura potenziali, precocemente individuabili. Questa catena non fa eccezione: pretende pulizia regolare come il resto della trasmissione, lubrificazione con prodotti adeguati, controllo dell'allungamento a cadenza ravvicinata per evitare sorprese, perché la sostituzione della catena rappresenta una spesa assolutamente abbordabile da chiunque e ovunque, la precoce sostituzione di pacco pignoni e corone della guarnitura rappresenta una spesa molto più onerosa e non ovunque attuabile. Preferisco sostituire la catena a cadenza ravvicinata, piuttosto che trovarmi con i pignoni o le corone che sgranano con una catena vecchia, ma anche con una nuova, perché nuova non è adeguata alle tolleranze raggiunte dall'usura dell'intera trasmissione. Meglio sostituire tre/quattro catene (circa 20.000km) che un'intera trasmissione, anche prima della stessa percorrenza. Consiglio il prodotto (e la trasmissione 3x), anche se non va di moda.
