5.0 out of 5 stars best chain for 5,6,7,8 speed bicycles, August 29, 2010

This is the best value for a multi-speed chain for a bicycle with fewer than 9 cogs on the rear cassette. I've found there is no loss of durability by choosing this over the more expensive 8speed chains(but 850 is probably worth the cost of a couple dollars more than 830), sram basically agrees with me (see [...]). With more expensive models, the nickel plating is mostly aesthetic and to arguably provide "smoother shifting", but smoothness of shifting is more about timing and technique, less about equipment. For hyperglide-style (modern) cassettes and freewheels, there is no reason to look any further. If you have an older freewheel with tall teeth, then you may find shifting works better with an older chain, but they're difficult to find, so this is probably your best bet anyways.

Most mountain and road bikes will work fine without removing any links. if you're concerned about chain length, the chain should be long enough so that in the two largest gears, the rear derailler can extend forward without binding. When in the two smallest gears, the derailler should be able to take up all of the slack and keep the chain tight.

if your bike is 5,6,7,8 speed this chain will almost certainly work well as a replacement

With all modern chains, a chain tool is only appropriate for removing pins from the chain, and a quick-link (one provided with this chain) should always be used to rejoin broken links. Chain tools are appropriate for rejoining broken links only on the side of the road/trail, and once broken, a link will never be as strong again unless rejoined as the manufacturer intended (e.g. quick links for sram and kmc, break-off pin for shimano).

People go through all sorts of ordeals to keep their chain clean and lubricated, with much of their efforts for little benefit. here's how to take care of any modern bike chain(older ones have bushings and it is more difficult for lubricants to penetrate, so care is different)
1. new chains are well lubricated, so install and ride it.
2. after several rides or the chain gets wet or dirty: hose off and then wipe off excessive dirt(probably not necessary for road bikes)
*wiping off the chain: prop the bike up so you can back pedal the drivetrain freely. wrap a rag around the bottom section of chain, which travels forwards as you backpedal. as you backpedal, force the chain to bend through the rag, frequently shift the rag to allow clean sections to absorb the filth.*
3. hold your bottle of lube so you can drip lubricant onto the chain while pedaling backwards. the best location is near the cranks where you can drip the lubricant onto the chain as it rolls over the front chainrings(excess less likely to get on the wheel's braking surface)
4. wipe the chain off using a rag as you pedal backwards. the more you wipe the better because lubricant is only helpful inside the chain, not at the interface between chain and gears.

if you follow these steps once or twice a month, your chain will stay fairly clean to the touch, and you'll probably notice how smooth pedaling is afterward.

I recommend replacing your chain once or twice a year, but this of course depends on storage conditions and mileage.

5.0 out of 5 stars Super Easy! Just remember to "Squeeze"!, March 23, 2010

Super easy install...went to W-Mart and got their $4.99 chain breaker, worked great. (The breaker is not the most substantial piece of gear, but for very occasional use like mine, perfecto.)

Just remember, when you want to take it apart, squeeze the master link together "inwardly." It's so easy to do right...and so hard to do wrong (I spent a while quite frustrated trying to "figure it out on my own" - one look at the manual cleared that up).

OH - one more thing - you have to get two "alike" holes going when you break the chain for the initial sizing...I broke it off one link too long (ending in a smaller "inner" link with the smaller hole) and the master link FRUSTRATINGLY would not fit through...I had to remove THAT "inner" link piece to make it terminate one "joint" back and then the master link worked. PHEW...frustrating but I got it.

I paid a few bucks more for this chain due to better reviews ("longer lasting" being the standout praise for it over the cheaper cousin that's a mere $5 or so less), and am glad I did.

Thank you!

seems to be a quality chain. the length was just right for my vintage 6 speed. the master link holds securely. 1st sram chain and will buy another when needed.
