    I ran one for awhile (maybe 6-8 months) on my old EG. I'm mostly positive about it on certain bikes.

    The plus: Cool technology. Set up properly (faced tabs, etc.), mine was dead reliable. Instant shifts in any situation. Chainguide/tensioner and bash in one package and you can run a short rear der.

    Minus: Bit heavy, bit expensive. Easy to set up badly. Some drag in overdrive (bit more than you'd get from a typical chainguide). Yes, you'll feel that drag.

    My legs are really used to a 22-32 setup. With the 22-tooth ring installed on the Hammer, granny is just what you're used to. However, it has a 1.6:1 overdrive, which puts you at 36-ish in the "big" ring. That goofed up my pedalling and I never really got used to it.

    That said, I'd run it again in certain situations.

    I have installed many of these in the last two years for guys and shops and I really love the dam thing , two that I installed are on my ridding buddy's bikes and they work so good that it should be criminal .

    I will have one on my next build , for an all mountain rider that really pounds his bike these things are really the ticket.

    Dion,

    Which situations would you run the HS? Up and down National riding? I have a similar body acclimation to the 22-32 front rings. That 36 up front never felt right to me and I had to go back to the 22-32.

    Firebird?

    Is it going on a Firebird? Mr Weagle has said the the HS and the DW link are not the perfect match. He designed the DW link to take advantage of the vertical movement of the chain line. Some of us won't notice the difference others will. YMMV.

    I have them on 3 different bikes. They work great, especially for those changes in slope (down to up) where you need a big change in gearing fast. Shifts are instant, even when stopped.

    They do require some maintenance. After about 200 hours I opened one up (requires a special tool) and did a clean/relube. Now it is dead quiet. I hadn't realized that it had gotten a bit noisy.

    The best part is no FD!

    I use Saint front shifters on all of mine.

    The only issue is a lot of chain slap on my Giant Glory. I am using the 22t ring on that one. Without a bigger ring I can't shift the chain away from the stay when stomping downhill.

    You should face the BB and the ISCG tabs before installing.

    The unit is very compact. No ring sticking out to get bashed.

    thanks all for the opinions. I did a very quick comparison of the weight vs. cranks\guard\tensioner etc and its pretty comparable, but I totally get the idea of a big hunk of metal right in the center of your bike.

    Blatant - nice write up. surprised that you didn't acclimate to the 36t front and just find a few gears that were your sweet spot, but good info to have thank you.

    Bobo - a Bird is on my short list, not getting one of these would certainly bring down the price. thanks for the suggestion.

    It works fine, but the 22-36 gear jump is way too big IMO, especially on a 29" bike. I spend most of the time in the regular setting and don't use over drive that much. Certainly never when climbing. I have to be moving pretty fast to want to use it at all.

    I am not sure if it is worth the weight, but I have not missed a shift or dropped or sucked a chain since I've had it and that is worth a lot to me.

    Maybe I should just run a single 22t

    One feature I like is that I it keeps my suspension very active since the gearing tends to pull directly through the line of my low pivot bike. I don't get any stiffening under power as would be typical with a middle chain ring. Some folks prefer that stiffening, but I prefer the suspension to stay supple.

    Anyway, 36t gearing is simply too much for me in most situations. Pity because that is the only flaw IMO. If it was 20t-30t equivalent it would be amazing.

    Edit: Read Dion's review...spot on. I keep mine because I am too lazy to swap and I live in the small ring 99% of the time (and the SS bikes get all the love anyway)

    I'm surprised to hear so many complaints about the 36t gear. My Iron Horse has a "traditional" FSA Gap crankset with a 22/36t combo. I really like it. It gives much less gear overlap than a 22/32t would, and the 36t offers a decent high gear and so I don't spin out too fast on the downhills.

    Interesting to hear that the Hammerschmidt might not be a good match with DW-Link, as that is the suspension design my IH has. Poo.


    Thx...Doug

    The HS is a great addition for the DW bikes, one that I installed was on a "firebird".
    The customer just loved it on his bird, he still does all the same tech climbs he did before and he had no loss of antisquat in low range and he still flipped the pro-pedal on at times in both ranges at times like he did before the HS .

    He was concerned very much about what affects might come about before we installed the unit , but 1 month after he was very happy to report that all was well !

    DW said that it wouldn't be optimal, not that it wouldn't work. That got blown way out of context many months ago, and although other manufacturers wont say it as readily, the same is true for most bikes in terms of their suspension kinematics.

    I am surprised as well that riders think the overdrive ratio is too high. I have always wished that it were higher. Currently it is only a 1.6 ratio, so equivalent to about 3.5 gear shifts on the rear. That leaves a lot of overlap. Going much lower would make the whole device rather pointless, imho. I would prefer a jump of around 2, so > 5 gear step. I suppose this would be the equivalent of a 22/44 combo up front, except that it is set up to use the entire cassette in either range.

    Having owned both the AM version and the FR version, I prefer the latter. It was quieter out of the box.
