Park Tool DS-1 Digital Scale

This would be a five star rating except for the strange fact that my scale doesn't work in the cold. I leave all my bike stand, tools and bikes in an detached, unheated garage. When I first took it out of the box and put batteries in them (3 AAA not included), it worked fine when I turned it on. It also worked fine when I weighed a few bikes. Then when I left it in the garage and tried to weigh another bike, it wouldn't turn on. I brought the scale inside to maybe start the return process but when I tried it a few hours later it turned on again. So I left it back in the garage and sure enough, below a certain temp (maybe 40s?), it refuses to turn on. So keep that in mind if you have an unheated space that you plan on leaving this scale in.Other than that, it's awesome being able to weigh parts (forks and cranks and stuff) as well as bikes.

Pluses:The scale works reasonably well. It is easy to install on my bike stand, which is not made by Park Tools.Drawbacks:1) If your bike had a sloping top tube, it is hard to hang it from the scale, using the hooks.The bike slides a bit, in spite of the "non-slip" sheathing on the hooks from which you hang the bike, when you weigh.2) I bought this item under the assumption that "Park Tools, USA" meant that the item would be made in the USA, like some of the other "Park Tool, USA" items that I own.Apparently, that is no longer the case! I believe this clearly reflected in the quality of the scale. I had to return the first one I got because the display was faulty -- would not display all digits. For instance, it would read " 7lb 05oz" instead of "37lb 05oz".3) For a $50+ scale, I would expect the manufacturer would include the necessary batteries. Apparently, that is too much to ask!

The scale was a bit pricey but Park puts out quality stuff so I know I will get my $$$$ out of it for many years. I needed a way to weigh a few bikes and parts and was going on a vacation with my wife where we planned on bringing back a lot of rum. I needed to weigh suitcases and that was enough of an excuse for me to justify the expense besides being a weight weenie. Weight is consistent over and over so far and I like that i can hang it from my rack to use it. I hang it off my jeep's hitch rack on rides to let people see that their $500 MTB bike doesn't weigh 21-lbs. That alone also made it worth the money. I would buy again, and have no problems with any of the Park products I own. I use it far more often than I thought I would. I weigh everything I can with it. Lets just say the cats went on a diet after getting this scale.

Nice display to read the weight and easy to press buttons. Not much you can say about this scale, it does the job it's suppose to do. Only thing I don't like about it is that it captures the weight quickly. If the bike is hanging of the hooks and swinging it can cause a slight fluctuation in weight as it swings side to side, I feel the scale doesn't allow enough time for the weight to settle to capture the measurement and can therefore give a reading that's slightly off, but not by much.

I like that it is accurate I only wish it would’ve came with a selection setting for grams.

If you are trying to minimize the weight of your bike, this is not the scale to use. It claims to have +/- 20 gm accuracy so when you weigh a 10 kg bike, the weight should fall in the range of 9.98 kg to 10.02 kg or 0.2% accuracy. Shockingly when I repeated weighing my 10 kg bike 10 times it show a weight between 10.06 kg to 9.88 kg or 1.2% accuracy. This makes it hopeless to change components like the chain or cassette or crankset and understand what the benefit is in many cases. For each weighing I was very careful to slowly lower the bike onto the scale with no bouncing in order to get the most consistent readings. The scale locks in the reading once it thinks that transients from loading the bike have died out. Then the reading does not change if the weight changes. You have to take the bike off and start again to get a new reading. This makes it very sensitive to how long you take to load the bike onto the scale and how much the bikes bounces around after it was loaded. If I took extreme care when loading the bike, then I could get repeatable measurements within 20 gm. Very touchy. I have ordered other scales with claimed better accuracy to see if they actually do better.

I ordered this scale so I would have a better idea of weight savings when swapping components. It's nice to know the weight differences when going tubeless or doing other upgrades. I hang it from my garage cieling, as I usually have a bike in the stand. It works well, and I do not have any complaints. As others have mentioned, the bike might try to lean one way or slip, but if you hang it from the seat I have not had any issues. Overall a good buy.

Cyclists tend to be "weight weenies" once they get into riding a bit. Accordingly, I had to find out how much my bike weighed, plus how much of a difference changes in equipment made.It works well and does the job effectively. The faceted neck allows it to be clamped by a bike repair stand easily.Also doubles as a scale for weighing your luggage, but it's a bit hard to lift. (Maybe mount it on your bike stand!)Mostly an unnecessary tool, but it's really fun, so what the heck, right?!

Nunca hace la misma medición del peso del objeto aunque lo repitas mil veces.

Works as it should. Seems consistent which I like.

Reliable and accurate.But you have to let the weight gently onto the hook. There is also a built in time that gives you the weight after a few seconds.This may not be accurate. So you need to weigh a few times until the weight is repeatable.

新品を頼んだが、中古品が届いた。量るたびに重さが変わる。返金を頼んだが品物を送り返してほしいとメールが来た。「ラベルの 1 つを印刷し、集荷前にパッケージにしっかりと貼り付けます。 参照用に 2 番目のラベルを保持します。DHL エクスプレス サービス ポイントに荷物を預けます。 locator.dhl.com でご希望の場所を見つけてください。」とかなりめんどくさい。しかも同じメールが3通も。あきらめるしかないのか・・・

Utilitarian. Functional. Fit for purpose. Worth the extra $20 for greater accuracy. Rugged.
