RedShift Pro Stem

I recently started reading some reviews of suspension stems.  Originally, TransX, but searching that, google had me looking at the RedShift stem.  The reviews were overwhelmingly positive, and so I started searching prices and RedShift.com had them at 20% off and free shipping.  Lowest price I could find.  So...  I decided with the discount it would be worth the upgrade to the RedShift Pro.  Got the stem a few days ago (super fast shipping), and so far, I really like it.  The ONLY negative is the extra weight (232 grams weighed by me, 3 grams over spec, I'm not complaining). There is no side to side play, or bob out of the saddle.  It just feels like my regular stem in that respect, but it definitely takes the edge off the bumps. It works best when on the hoods (leverage), but is noticeable even on the tops, and when in the drops it feels kinda in-between. At higher speeds, the effect is also more noticable.  I still haven't done any brutal gravel with it yet.  Seems like a winner though.

I just got mine too and agree on all points.  I’m 155# and left the set up as it was set up.  I’m looking forward to getting this onto some bumpy roads

Love mine. I actually went one level softer after a few rides. You should try that.

Got mine an installed but haven't ridden yet.   I'm a big toad at 6'4" 270# and am wondering what elastomer springs to start with?

You should have a chart.  I went maximum on mine, we are very similar in size.

I'm 150# but I ride pretty light on the bars.  I just switched my Blue(70) / Orange(60)  to Orange(60) / Yellow (50).
I hope to get out on a ride today to try it out.  😉

I'm sure most people are aware, but where you like to ride on the bars (hoods, tops, drops, etc...), stem length, handlebar reach, and how much of your weight is on the bars compared to your arse, will all affect what you need for elastomers, and unless you stay in one position on the bars all the time, it's going to be a compromise.  I checked out the 60 / 50 combo today, and it felt better. Some barely noticeable bob out of the saddle, and  softer all around.  In the interest of best scientific experimentation protocol though, I changed all of the variables at once, 🤣  because I had a tire failure my last ride and switched from 43s to 40s (another topic).  But...  Imma give it a few more rides and see if I want to firm it up a little.  Overall, still liking it, and liking the adjustability.

About setup: temperature also affects the elastomers. The hotter the day, the softer the ride. Firmer in the cold.

I didn’t think of that, and with it being winter here and my last ride at -10C, it can only get softer from this point

The chart only goes up to 205 lbs.  I got creative for my wife's setup because she's bulking for some Olympic lifting nationals.  I upped the lighter elastomer by one color, but we haven't tried the bike yet.

I asked Redshift about this and they claim that their elastomers are unaffected by temperature. I find that hard to believe.

I have ridden the stem at 114F and 10F. The elastomers are definitely affected by temperature. Maybe not as much as some, but affected. 

Good to know, thanks!

A couple hundred miles on it now with some gravel climbs, descents.  I'm really liking it.  I was riding in 32F weather yesterday with some gravel and dirt, and it may not have been quite as compliant as when riding in 60F, but, pretty close, but because of the different roads and conditions, it was hard for me to tell. It still makes a big difference, especially at high speed on washboard / ripple.
