Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

?? about SRAM PC1 chain

Just bought it and am attempting to fit it on my bike. I'm going to shorten it with a chain tool but what doesn't make sense to me is..what is the purpose of this snap lock? Do I need it at all or can I just do remove and add links with the chain tool?

it's called a masterlink.
if you don't know what it is i would consult sheldon.

snap lock allows you to remove the chain without a tool...which can be handy. I've had them on a couple bikes and they're fine. in fact, I'd trust the snaplock more than a poorly rejoined chain...

the one on the PC-1 isn't exactly the same as a traditional masterlink....

if it snaps apart on its own i would still be wary of using it.

Yes, no need for the masterlink unless you want it. Just attach the links with the chain tool and you will be just fine.

I have the same chain. I forwent the master link and did it regular old style. I feel safer that way.

Its actually a better idea to use the masterlink. Since the chain was designed to use it, the pins aren't designed to be re-inserted. z

I've been using the same PC1 for about 5 years with out the snap lock. I have taken it off probably once a year using only a regular chain tool and it has been solid - although I've been using it on a ss not a fixie and it probably gets less stress.

I run mine traditional stylee, but the link is a bit stiff at first when I put it together, but other than that I have no real issues or concerns with it. It's a good solid chain for little money.

Where does that piece of info come from?
AFAIK all Sram chains are chaintool friendly. The masterlink is just a plus. I use it BTW and there is absolutely no reason not to.

Yeah, the idea that the chain is not designed to have the
pins reinserted is an obvious fallacy, and not just because
the PC1 is a single-speed chain. How on god's green earth
would you plan on shortening a chain if the pins are not to be
reinserted? No bicycle is the same, and they all require a
different length of chain, and unless you can special order
SRAM chains with the exact number of links you need, then
the only reasonable conclusion is that these chains are
designed to have reinsertable pins.

Not quite. Shimano chains do have non-reinsertable pins, and there's a special pin for assembling them at home. But Sram is different.

i have never managed to successfully use a masterlink. maybe i'm a ****, but one of those two-plate dealies with the clip that holds the plate on, i just can't get the clip to get on over the pins without getting it bent out of shape (or without me getting bent out of shape). wtf.

5 years? Yikes!. Check your chain for stretch. Its gonna ruin your drive train...it probably already has. 5 years is too long if you ride regulalry. I go through 6-7 chains a year. Replace that chain!

yeah, I know - I didn't really mean to do that and I checked for stretch a couple of days a go - I won't even mention how bad it is - got a new one now and you're right ......On all of my other bikes I have always chainged the chain at least once a year so I've never really seen this happen (ugly)- guess it is time for a new chainring, cog, and more respect for my transportation rig!

I'd just leave that drivetrain as it is unless it's giving some problem.
With a fixed/ss, the chain can stretch as much as it likes-there is no escape. It can't fall off the cog so the whole drivetrain will work until you wear out the cog so much that the teeth start snapping off.

Now that you've definitely damaged your cog+chainring, why not torture them a bit more?

as an aside: i have found shimano chains to work quite well with the old pin re-inserted. i know they recommend against, it but it works for me!

also, after having more than one chain snap at the quicklink i no longer use them.

imho, IT IS THE WEAKEST LINK, GOODBYE!

The traditional clippy ones are supposed to slide on from the side, not over the top of the pins. Just push it with a screwdriver.

I have SRAM PC1's on two bikes, one geared, one SS. Love them. Haven't had any problem in over 2000 miles between the two. I take them on and off about once a month to clean the chain. Much prefer using a pair of needle nose pliers instead of a chain tool.

Normally, I'd say keep a good chain on there to get the most out of your cog and chainring, but once you've reached the point of no return, you might as well ride it until there are no teeth left.

You're right, I was thinking of the shimano chains. Still, I like the masterlink.
