PC-971 9 Speed Silver/Gray Chain with Powerlink

I've been using SRAM chains for about 25 years and as far as price, durability, and just all around reliability this is about the best chain for 9-speed drivetrains. Highly Recommended.

No doubt this is a great choice in bike chains. Would not for a min. Hesitate in recommending as a great replacement chain . Just a quick note you may want to concider. Like most of you I try my best to get the most from my investment. Lots of expensive fancy lubes. Special chain cleaning machines and the end result is the chains seemed to wear out rather quickley. Here is what I discovered. Once you add oil to you chain problems begin. 2 seconds into your ride that fancy lube changes from a lube to a very efficient lapping compound. The dust and grit begin the fast process of grinding your new chain to a quick death. Even the so called dry lubes are not much better. What I now do is super simple, inexpensive and tripled the expected life of the chain. Plus no more oil on the pant legs all components stay clean and shifting is greatly improved. Couple of blocks of Parrifin canning wax melted in a pot. Soak the chain. Hang and let cool and install. Simple. Using a park chain gauge I can not believe how much longer these great chains last. Best of all no more mess. Check Youtube for videos on how to wax.

SRAM makes a great chain. I've been using them for probably 15 years. Obviously a chain isn't a very glamorous item, but by creating their power link technology, they have really revolutionized putting on and taking off a chain. Works great. All you need to do is use the chain tool to adjust length, and then you're good to go. This chain was to replace another SRAM chain, same model. By the time I replaced it, it had been on my bike for close to three years. For most of that time I was commuting on my bike. Now I lived fairly close to work, so that was only maybe a mile or two per day in commuting, with maybe another 20 miles a week in longer distance rides when the weather was nice. But still, that's probably between 600 and 1000 miles per year, and in all weather. I would ride in rain, snow, etc. During that three years, I would regularly measure the chain for any wear or stretch. And even when I replaced the chain, there was still minimal stretch. Under 1/8", measured over 6 full links, or 6 inches. It also did great as far as performance: drivetrain was always smooth. Everything was SRAM X-7, with a Truvativ Firex crank, and it was always silky smooth to shift, and very smooth when pedaling. The only reason I needed to replace the chain was that I was overseas a lot last year, and it sat in a friend's garage for over 4 months, with absolutely no attention at all. So that old faithful chain finally succumbed to rust. I'm sure I could've brought it back if I had given it a good cleaning and lube, but I figured after 3 years, I would just treat my bike to a new chain.

Great quality and easy to install with a link.

I have been using Shimano chains for decades. I’d decided to give this a try due the the simplicity of the power link. No guessing if the chain rivet is in the perfect position or not. I could not be more pleased. I use this chain with an XT chain ring and a Rolhoff rear hub. Meshes perfectly. When I installed this chain, i left it a bit tight because in my experience, all chains stretch a bit on the first few rides. After 3 rides 80km this chain had not stretched a bit. I had to adjust my exccetric BB to give the chain a little slack. I am not sure if this chain is better than shimano with a derailleur or not, but for single speed or geared hub, i am very impressed. The power link also makes th chain easy to remove to clean and reinstall in seconds.

This is a great chain for the price. I knocked it down a star because SRAM does not provide installation instructions, so I had to look them up on my phone with greasy fingers. Further, the instructions I did find were generic to several different chains, so kind of a hassle to figure out. I do appreciate the provided master link. That made installing the chain literally a snap (that's the sound the link made when it clicked into place).

After several thousand miles of use, I needed to replace my SRAM bicycle chain (on my Specialized Roubaix road bike). The chain worked very well, so I bought the same chain, SRAM PC 971, thru Amazon. The pricing was excellent, and I qualified for free shipping over $25 when I bought 2 chains (always good to have a spare around, I say). With its PowerLink connector, installing the new chain (and taking off my old chain) was super easy. The only tool I needed was my chain tool for removing excess links. Fellow bicyclists, if you have no time for any other maintenance, always try to be kind to your bike's chain! Keep it clean of dirt & grease and oil it periodically (no need to spray oil all over everything, only the rollers need one drop each).

I own a racing road bike with 8 speed cog cassette in the back and triple crank in the front. So, its a total of 24 speed. I have noticed that the original 8 speed chain by KMC always having hard time shifting up and down gears in the back cog cassette. So, I read about people changing their chain into more narrower type like the 9 speed or 10 speed chains because they are mainly use for more cog gears in the back. As soon as I changed my 8 speed chain into a more narrower 9 speed chain, I definitely can feel the BIG difference in shifting in the back cog cassette gears. It became more smooth and easier for sure. So, the thicker the chains are, the more noise you will hear when shifting on the cog gears, because it is rubbing between gears. The narrower your chain is, the smoother it shifts. Shifting in my triple crank in the front becomes a little bit smoother too, although I really have to hold the shifting lever to be able to shift from my 42 teeth gear to higher 52 teeth gear in the front so that the narrower chain will able to catch the higher and bigger gear. But for downshift, no problem. Just notice also that I deducted about 2 links of chains from the 9 speed so that it would be the same length of chain with my 8 speed. So the the rear derailleur in the back is not too far back or too loose with the longer 9 speed chain. You have to do this to have the right length of chain for the derailleurs.

Cambié la cadena de mi bici por ésta porque estaba harto de que la Shimano que montaba se abriese cada dos por tres. Esta parece muy resistente y, aunque sólo la he probado con la bici en un caballete, parece que cambia más fino que con la anterior. La colocación es super sencilla: basta con ajustar a la longitud apropiada, quitar los eslabones que no hacen falta y cerrar con el cierre rápido, lo cual evita que se pueda abrir por quedar mal cerrada con el tronchacadenas. Por cierto, que también viene preengrasada... PS: Tras probar la nueva cadena rodando en la bici saltaba mucho cuando engranaba dos piñones intermedios (cassette Sram de 9v). Anduve un par de semanas así para ver si era problema de acoplamiento cadena-cassette y se solucionaba con el rodaje, pero no fue así. El problema venía del propio cassette, que debía estar gastado. Cambio de cassette y problema solucionado. Parece ser, por lo que he leído en algún foro, que los cassettes Sram acumulan desgaste con cierta facilidad y cuando se cambia la cadena aparece este problema. Lo comento por si os pasa a vosotros también...

Presa per sostituire l’ormai logora catena della bici con trasmissione 3x9 di mio papà. Il numero delle maglie era giusto così non ho dovuto accorciarla, con il quick link si monta in un attimo. Con una bella pulizia dei pignoni e delle corone e Senza fare nessuna regolazione al cambio che era già Ben regolato la trasmissione è più precisa e silenziosa. Ottima catena per chi non cerca la Massima leggerezza a tutti i costi

Mit der SRAM Power Chain 971 9-fach Kette bin ich zufrieden. Der Kettenwechsel ist durch das nietfreie Kettenschloss einfach und kann auch ohne Kettennieter unterwegs gemacht werden. Ich habe sie auf dem Trekkingrad mit der Deore XT 3/9 Schaltgruppe. Sie läuft sowohl über die Ritzel wie auch über die Umwerfer sehr ruhig und erlaubt präzises schalten. Bilder: Nach 5000 km knapp an der Verschleißgrenze für Stahlritzel / SRAM PC 971Kette wieder neu - gemessen mit Rohloff Caliber 2 Kettenverschleißlehre. Als Kettenschmierstoff verwendete ich bisher Finish Line Wachs, bei der neuen Kette Finish Line Keramik Wachs. Der Verschleiß von Kette und Ritzelpaket ist belastungs- und verschmutzungsabhängig, hängt aber auch davon ab, mit wie viel Schräglauf die Kette beim schalten läuft und wie oft man im Wiegetritt fährt. Eine Kette kann deshalb knapp 2000 km, bei groben Schaltfehlern sogar weniger, besonders bei Stahlritzel aber auch über 5000 km halten.

Viene bien cerrado en su blíster e incluye su conector powerlink. Estoy muy satisfecho.

Chaine de bonne qualité, elle parait solide et bien fabriquée, à voir sur la durée. Elle arrive un peu graissée, mais je recommande de rajouter de la graisse dès le premier jour pour éviter les problèmes ultérieurs. Le montage est très facile avec le maillon fourni pour la fermeture de la chaine.
