I have the Redshift stem and I stand a fair bit when I ride, probably more than most folks I have ridden with. I have mine setup on the softer side for my weight, 185ish, and I am fine with it. If I push really hard I will feel it flex a bit but now that I'm used to it, it doesn't bother me at all. I would say the squish is pretty linear so it feels like your front tire is softer than it really is if that makes sense? My opinion is that the stem brings way more than it detracts.

Thanks, that's helpful. Have you noticed any play in the joints, i.e. motion other than vertical?

None at all; I am really happy with the Redshift stem overall and I consider myself to be pretty picky about my bikes..
I have 6 degree Redshift on both my gravel bikes and echo what stu said. Standing going up short steep hills , which I do alot , I don't notice any movement except slight verticaI which is easy to get use to. I set my Redshift to be a little softer than recommended for my weight of 180# to get full benefit of road chatter attenuation and it works very well for me. BTW, my wife rides with a 30 degree Redshift stem shock , and I do think it feels a little sloppy for me when I test it on her bike --tho it is set for her weight of 120#---which may be a factor in sloppy feel.
I also ride the Redshift and love it. I do run it a bit more firm - one step above my weight range. Unless you really focus on it, you won't feel it moving while climbing out of the saddle.

I'm 190 and ride the Redshift 100/30, and can tell you there's NO slop in its rigidity. This is a VERY solidly-engineered product...maybe even TOO rugged, as I wish it were a little lighter. But that 380g "accordion" is a joke!
I bought a Redshift stem on their Black Friday deal last fall. Man, do I wish I had done so years ago. Great product and definitely worth a small weight penalty.
Reviving an old thread, but after hitting on a couple posts about the Redshift stems, I started doing some investigation, reading reviews, watching Youtube vids, etc., and decided I needed one. The site is currently offering 20% off normal price so I sprung for the Pro version to save an extra 40+ grams. I'm looking forward to it. Both of my hands have got age and injury related problems (bike crashes, etc, that required surgery of one type or another. I still have a broken steel pin in the thumb joint of my right hand). Downhills with coarse gravel, and ripple are especially rough on my hands. Hoping the Redshift stem will help. 😉
Still using my drilled-out 100mm/+30deg with fine success. Mates well with the Ergon/Canyon-clone split-beam carbon compliant post as a duo too. (You can save almost half the weight delta of the PRO by swapping out the heavy cap and getting Ti bolts. I drilled 18 holes in mine to shed the remaining mass!) I then taped it up; maybe someday I'll unwrap it and show a pic.

The Pro version comes with CNC machined end cap and Ti bolts. I'm not drilling anything. That's old school cool, but can end very badly.
Indeed, I'm not recommending unplanned power-drill attacks. The older original RS has a VERY thick shank, so will tolerate major shedding of mass without compromising real world strength...especially as it compresses a full 20mm before hitting solid end stops and stressing the body. Finding CNC end caps and Ui bolts is easy, and of course a drill press or at least your grandfather's old bench vise is de riguer. It's 16degF here, so maybe I'll unwrap mine to take a pic in the spring! I used perhaps 8mm bit for the larger holes, adding maybe 5mm ones to finesse it. Shed about 20g. A fine comparo is with that German (?) TransX stem which uses a simpler compressive sleeve to absorb about 1/3 the shocks of the RS, but weighs MUCH less, using a thinner body stock. I use one of these unaltered on my road bike to save weight and afford minimal vibration transmission. Note also that I sent pics and vetted my drill-out to RS, whose design engineer was impressed by my indie mass-shedding iteration. The process took me an hour, so I'm repeating the process except maybe as a favor for 100mm/+30deg users who cannot buy a PRO version. The TransX seems much less noticeable on big hits, of course, as it has only 1/8" (3mm) compression, so think of it more as bigger tires or extra bar tape in effectiveness. Yet its lightness and design makes it an easy $99 choice for road use.
I looked at all of the info I could find on the TransX too, and it does look like a reasonable option to take the "edge" off rough tarmac for road bikes maybe, but seems a little to limited (for me), for actual gravel descents, etc. I'm hoping the RS Pro will be significantly better in that regard with out too much of a weight penalty. What's too much? Well, I'm a recovering weight weenie, so I'm probably going to be disgusted with the weight of the RS Pro, but I'm in recovery, and it is a gravel bike. 😂
