Awesome!

Weird day 2” axle up to 315 3x1 tried a large shoe but didn’t have it. Decided to switch direction 0 pony

This morning I ended up making a new makeshift rgc tester with steel bars, and it turns out that the gripper ramps up a LOT in the last 5mm. The final rating was 348lbs. Not sure how 400+ failed to close it. Here's some photos of it if you're interested. It's worth noting I had to tilt the gripper a lot to keep the strap from sliding off, but I think I did a pretty reasonable job of finding the sweet-spot angle.

Even more importantly, not only are the numbers comparable but they will be proportional, meaning you don't actually gain information by doing this. If you already have an RGC rating you can use that to derive what the rating would be by using a large or smaller strap, nothing new is being added. It would be more helpful to quantify the spring constants to see how hard the sweep will be, as that and the spread are the biggest variables that make two grippers of the same RGC have different actual difficulties.

We rated one of these recently and it maxed out our rig at 400lbs. It was ALMOST shut. The actual rating would not have been too much higher.

Finally, some motivation for the 1” strap was based on the fact that the weights are lower. If you’re physically lifting weight over and over for 7000 grippers, there is some motivation for it to be less weight. Especially when the actual numbers don’t matter when the only goal is that they are comparable to each other.

I know its not bench press but I am feeling really strong this cycle. Here is the Top set of seated shoulder press DBs from Yesterday with 110lb DBs for 5x. I think I had a 6th if I really went for it.

Also, using a strap that mimics the width of a hand will still not mimic how grippers feel in the hand. You’re still only getting “pounds at the close”. The only thing you’re accomplishing is a different set of numbers which will only be comparable to ratings taken in the same way.

Nice!

Yes 1”. The value in ratings is so that you can compare numbers, literally nothing else. Doing anything else with the strap will just increase the numbers. Why? Ego? The resulting numbers will simply be comparable in the exact same way, just higher.

This would fit better in the equipment section rather than the training logs and routines section, unless you plan on using it as a log. Yes, axle is great for all those things you mentioned. 100%

I figure a full strap would be a similar number you’d get from a dynamometer?

Everyone have different sized hands so I really don't think it would be a good way to measure. I think the best way is the RGC standard we already use. Rating furthest out on the handles, will give you a result which shows the least amount of force it requires to close the gripper. Regardless of hand size. The use of hand dynamometers should be good enough if someone is interested in testing in another standarized way.

Awesome info here! Thanks

I think this is a good idea in theory but impractical in practice because it means you'd need to put a lot more weight on to rate grippers which can already be hard to rate, I think the future of RGC is using a sensor to graph the resistance curve of each gripper spring

A large strap gives you a higher rating, and a smaller strap gives a smaller rating assuming the edge of the strap is still aligned to the end of the handle. You're basically just moving the load point up or down the handle since it will always be measuring from the center of however wide the strap is.

I’ve always felt it needed this, too.

Hello gripper calibrators I have a question. The strap in RGC rating are generally 1 inch correct? Our hands aren't one inch in width. I am curious to know how will the RGC rating will differ if we use a strap that mimics the width of the hand? Any takers?

I believe ours are from a second batch.

Thank you, brother! Mine is 8 of 25.

Man your video is super motivating for me! Your #3 close is crazy too! I have to attach weights to myself when I try and force it closed because I weigh too little and my feet come off the ground when I bear down on it 😅 Just curious, what does the bottom side of your monster gripper say? Mine says, "JK 6 of 25" and I was wondering how many he made in total.

I have one ordered can’t wait to work with it.

That’s some heavy stuff! I can’t believe I was able to just touch the handles on mine years ago. I was beastly 😀
