    2 powerlinks on an SS chain

    Is it possible to run two powerlinks on a single 8spd SACHS/SRAM PC59/PC69 for SS use? Read on for the long winded version, but I'm sure if anyone has done this (successfully or unsuccessfully) they can let me know...

    I'm currently running my Bontrager without a tensioner and on (32/36/40):18, depending on terrain - we have a good range of countryside locally and within one or two hours drive. I've currently got a Deore disc hub with spacers and a DX cog, but my Xmas present came yesterday and so it's about to be replaced with a King SS hub and boone sprocket :-) Up front I have an XTR 952 crank with a Forge 36t spiderless ring (UK equivalent of spot/jericho/boone). I have a 32t Forge which has been very rarely used as it's a (relatively minor, but then I like thigs to be super simple) pain to change the spider each time I want to change the ring.

    The other day I managed to pick up a lightly used XTR M951 crankset for very cheap, so I've installed the 32t on this and hope to make most of the money back selling the rings. I've been planning to have two different length chains and swap out these and the cranks when I want to change the ring, as with self extracting bolts this should be simple. I got to thinking that I should maybe use a powerlink too, to speed up the process (I never have even on geared bikes, as I have a really nice chaintool and have only had problems replacing pins on Shimano chains back in the day). Then I thought that if I have one powerlink in there, why not have two, so that I can split the chaain, remove four links (with a powerlink at each end), rejoin it and swap the cranks over, and all I have to take is the four spare links instead of the spare chain as well.

    Anyway, hope someone has had experience or some input into this,

    Ian

    Done that

    I've used as many as 3 powerlinks on my chain without snapping it. YMMV though...

    Now I have two bikes: one beater for the road commute with a taller gear and another off-road with the appropriate gear, so I don't do it anymore, although the chains still have one powerlink on them.

    Personally, I would prefer swapping chainrings as opposed to the whole crank arms if at all possible. The wear and tear involved is more costly IMO.

    Cheers,

    Maurice

    Yup. Done it.

    I ran a 44:16 for commuting and a 34:18 for dirt, which is 8 half-links difference. I could remove the three links and one power link, switch gears, and I didn't even have to unbolt the wheel.

    Cool-blue Rhythm

    I do that for when I flip-flop the the rear wheel on rides where I do a combo of MP and and ST. IMHO, since you're going through all the trouble of swapping out a chainring, you may as well have two chains, each of the size you need for the ring you're gonna run. It's not like you're going to be doing the swap mid-ride.
    I gotta roll, can't stand still, got a flame in my heart, can't get my fill.

    I've been known to run 2 power-links and a half-link. (Or was it 2 half-links and a powerlink?)

    Very doable

    I've done this a number of times, to allow me to change chain lengths for big changes in gearing. Still takes a couple minutes, though, and unless you've been riding in dry conditions it's still messy. A two-ring/two-cog setup allows for much faster and cleaner gear changes, for anyone who has the option.

    Technically, there's no problem with multiple PowerLinks in a chain, and as far as I'm aware there should be no practical limit to how many you can use. They are supposed to be stronger than the regular links, if anything.

    I haven't tried it, but I did not know that 'magic' gearing went to 32/18 on a Bontrager...interesting indeed.
