I just got the SID SL brain installed on my 2021 chisel last week and today I went for a trail ride. Here are my impressions.

The fork on the bike before was a Judy silver. The front end of my bike is super super light as the SID is 2 pounds lughter than the Judy Silver. Steering felt sharp, crisp, direct and very nimble. I’m not sure if that has to do with the weight not being on the front end or the slight difference in the offset. I also noticed that low speed technical climbs the bike wandered less and was easier to keep on a line.

The feel of the fork is very firm. I have it set up as the rockshox app suggests. riding weight is 190 geared up and I gave 127 osi in the fork. Rebound us -7 clicks. I have the brain fade adjustment set to 1 click from the softest setting. When standing and cranking the fork compresses maybe 10 or 15 mm.

The first part of my ride is flat and slight uphill and fairly tame. I wanted to see how much travel the Fork was moving and it wasn’t moving very much at all. Wouks live mire small bump sensitivity. The second part of my ride is steep technical climbing. The light weight was obvious. The steering and control improvement was obvious as well. Losing 2 pounds off the front end makes a big difference. The next part of my ride is fast, rocky, bumpy downhill. I probably reach about 25 to 30 miles an hour in sections. I reset the travel O-ring indicator and took off down the trail. When I got to the bottom of the trail I indeed had used 100 mm of travel. The bike felt planted and I had loads of traction and front end grip. On the negative side it was a bit harsh. More harsh than the Judy which in my opinion was a lot softer. The next part of my ride was a medium speed single track that is flowing in areas and has some twisty areas and others. This is where the SID SL really shined. This was so much fun! I forgot about the fork and just had fun riding. Handling was crisp and traction was perfect. It put a big smile on my face as I was riding. Bonus was when I needed to stand up and crank I didn’t have to think about locking out a fork or anything like that. It was automatic.

So my overall impressions are pretty positive. The fork works better than the Judy silver. Which is obvious. It’s a little bit harsh on high speed bumps and on small bumps it probably doesnt have enough small bump sensitivity.

The question for anyone using the SID is, is there a way to set it up to be a little bit more plush and less harsh? I’m thinking about dropping the air pressure a little bit which should improve the small bump sensitivity but I don’t want it to be so soft that I use up all of the travel. Also the rebound settings were again set per the suggestion of the rockshox app but less rebound less harsh? So maybe play around with that setting as well? Also the brain fade adjustment. I have it set fairly soft maybe I could firm that up just a bit as well as drop the air pressure and see how that works together. Any tuning ideas or suggestions would be greatly appreciated as this is my first shock that I’ve had to tune more than just setting the air pressure.

220 pounds rider here with own the select+35/120 on a ht. In my case I found a nice balance adding 1 token and lower the air pressure a bit. The fork feels more progressive with a better small bumps compliance now (take into account that my rides are not that technical).
I did play a lot with the rebound knob and the pressures and for my liking I settle down to lower pressures that the ones recommended by the Rockshox app.

Thanks for the review. I just ordered one today for a new ti ht build. Looking forward to not playing with a lockout. Hopefully I like it.
That aspect of it works brilliantly! In fact, it all does. I would just like to have a softer, more plush feel on small bumps. More small bump sensitivity.

Just looked at my pics and realized the fork was only using about 60% of its travel. In comparison, I know the Judy was using most of its 100mm of travel and on my last bike the Suntour Coil fork was bottoming out on the high speed downhill section. I am gonna drop the air pressure by about 10 psi and see how that feels. I would bet those recommendations put you on the high side so it doesnt bottom...also a fork like this is probably set up alot more specifically for the rider than a Judy, which is pretty much set it and ride.

After the ride that was the most travel I used even on the rough downhill section that usually needed alot of travel.

Update...dropped the air pressure to about 110. WOW. What a difference. Much more "plush" and great some bump compliance. I also didnt get 100mm travel yet either and the sag is about 20-25%. I could probably go even less pressure and get 30% sag height and still probably not bottom the fork out.

Couldn't wait for the new frame so I put it on my Sniper. Absolutely love it. 1 ride and 1 race in couldn't be happier. Getting about 95mm travel straight out of the box, no bob. Sitting at 25% sag. Ride with about 3/4 fade. Transformed the bike.
