Shimano CN-HG901 11-Speed 116 Link Sil-Tec Chain

I bought this to replace my original HG701 symmetric Ultegra chain. I run R8070 Ultegra Di2. This doesn't come with a quicklink, nor was I expecting it to do so. I bought a pair from Decathlon, which work perfectly well. After fitting the chain to size (compact with 11/34), I went for a ride. I was pleasantly surprised with the shift quality, which I expect is down to the asymmetric chain. Shifting seemed smoother, which was quite remarkable given the already superb shift quality. Another commendation is how quiet this chain is. I suspect this is the sil-tec, but compared to my old chain, but I barely realise I'm moving. Even after 150 miles of wear, with a tailwind a couple of days ago (so no wind noise), I was going at 20 mph and the only sound was the slightest hum of the tyres. Truly remarkable, and a marginal gain on efficiency. For the price (a couple of bob more than Ultegra) I think this chain is well worth the money. I really cannot fault it. Just remember to buy your quick link if you want one.

I thought I’d give this a go after using KMCs for quite a few years. Paired with a new DA cassette and some nice Ceramicspeed chain wax stuff it is pretty nice. Lovely shifting, just lovely.

Great value for money and a brand you can trust for the highest quality

Dura Ace chain as described - unlike one of the other reviewers my didn't come as the version with a quick link supplied

Received a different chain to that advertised. Not the genuine Shimano box and chain was of a different spec (tell-tale solid pins), but printed as if it was genuine chain. Seems from a quick bit of research that fakes are rife, avoid.
