    A Tip for Getting Pins Back in Chains

    I don't know if anyone else has had this problem, or if I'm branding myself as an idiot by having it. Be this the case, than those like me can benefit, while the rest of you can scoff at me, and rightfully so.

    In shortening a chain yesterday, I pushed a pin completely past the plate. I thought I was ruined, except my genius girlfriend though of using a bobby pin to hold the chain pin between the chain tool driver and the plates so that it could be driven back through.

    Two pins, one chain, a happy bike.

    I learned this the hard way as well. Don't push the pin all the way out.

    I stopped reusing chain pins when I realized that I was using chains that didn't recommend it.

    Unless it's a singlespeed chain, modern chains aren't designed to re-press the pins.

    Save your old chains and cannibalize. I've poked out at least a handful of pins and popped them back in without damaging the chain.

    If you have the typical $6-7 chain tool, place a thin washer between the handle & frame to prevent the "Screw" from going too far. After a bit of trial & error, I've got one that works near perfect.

    Ummm, every Ultegra chain I've bought in the last 10 years came with 2 break-off pins.

    It's not a matter of damaging the chain. The chain being so thin, the risk is getting the pin off by a fraction of a mm could cause it to not hold under a load, which means the link will come undone while you're at your hardest effort. That will send your foot straight to the ground, bringing you and the bike with it, at whatever speed you got to before the pin let go. Sure this is a rare occurance, but why up the risk by doing things wrong?

    A guy died here in richmond a year or two becuase of this. He was pedaling hard out of the saddle going down a hill on a group ride. His chain let go and he smashed head first into the tarmac. His wife was in the following group. He was dead by the time she rode up to the crash.

    I've re-used Shimano pins before to see what happens. If you're careful, you can get the pin back in place and the chain will look good as new...

    But then, after going for a slow, casual ride on flat ground, the pin begins to separate from the chain. So it can work in emergency situations to get you home, if you take it easy, but NEVER would I actually ride a chain with a re-used pin.

    Always us a quick link to re-assemble an chain after shortening them. There is a removeable link for almost every chain you can buy. I keep one in my tool kits (road, MTB, and XC) and have ended up helping a buddy get back home by using my QL. They are easily removable for giving the chain a truly good cleaning.

    Yes, it's a matter of damaging the pin actually for shimano chains anyways. You shear off the peening on the pin which makes rejoining without using the special shimano rejoining pin a disaster waiting to happen.

    Penny wise pound foolish. This is a disaster waiting to happen. Please, just go buy the $2 masterlink if you've pressed out the original pin. You'd literally have to be completely drunk not to install one of those back onto your chains correctly.

    No "feeling" the pins to see if they are protruding evently, and no guesswork involved. There's no reason why ANYONE needs to use special pins to rejoin their chain anymore. Time to join the 21st century and maybe it'll save your butt one time.

    There is absolutely no financial or practical sense in using *any* chain which does not feature a reusable masterlink. There are literally no disadvantages to this system.

    So then, why does Shimano not do it, and why has SRAM stopped doing it?

    Think they might know something we don't?

    I don't know why Shimano won't do it, but it's one of two reasons I hate Shimano chains.

    As for SRAM, when did they stop doing it? I still see PowerLinks and PowerLock links...

    How many would you like? I already responded that I find 2 pins in every Shimano chain I buy. That's usually plenty since my chain wears out as often as I find a reason to break the chain. Plus aren't extra pins like $7 for a pack of 5?

    Thanks, I did not know that much actually.

    Their 10-speed chains include a "Powerlink", but they are single-use only which makes them essentially the same as the Shimano pin. (The older links are re-usable as always.)

    Rumor has it the newest Dura-Ace chain will have a quick-link.

    Yes Shimanos new Dura ace will have a replacable qwick ling for their chains. Seems like Sram is scaring shimano abit more as they have done that and the new DA brifter is running the der and brake cables under the tape for 09'.
