As advertised! This is the second one I've purchased. Kit incluudes the powerlink which makes for an easy to install. Perfect replacement for Giant Roam 3.

Pas chère et fournie avec un maillon rapide, nickel. La graisse colle pas mal. Prévoir un bon nettoyage au white si vous voulez opter pour un lubrifiant sec (cire, parafine, Squirt...)

I used this for several years (until I changed my driveline for 10 speed). I rode the London-to-Brighton with this chain (and, yes, I did pedal up the "Beacon") also used it for my Randonneur-qualifying 200km (125 mile) ride. Survived several winters of salted roads, despite my pretty minimalist approach to regular bike maintenance. I checked it with a chain wear gauge, and there is still plenty of life left in it, so it now lives in the garage as a "spare". It will fit 6,7 and 8 speed bikes and is FAR easier to clean than a chain without a special "quick link". Recommended.

Cadena Sram para cambios de 8 piñones, viene con un cierre rápido incluído y tiene un buen precio. Poco más puedo decir de esta cadena excepto que el cierre rápido me costó mucho cerrarlo, si os pasa esto, colocais la cadena en su sitio con el cierre rápido en la parte superior y dais una pedalada fuerte y seca y se cierra pero con la mano me fué imposible. Una buena cadena que espero que dure tiempo porque es para una bici de batalla.
