Bike shops are doing their booking for next year. I'm interested to order a SJ Expert in size S2. Can anyone tell me the weight of a Stumpy Expert in size S2 ?

Anyone else find the Fox 34 Grip2 overly harsh? Ive tried a few settings and its not nearly as plush as the Pike on my old bike. Would like to hear your thoughts. Ive got a 2021 Stumpy Expert with the performance elite fork. The rear of the bike feels like butter but the fork doesn't feel right.

I have been really struggling with the fork but I think I have it figured out. First, my negative air spring was filled with grease. A lowers service made a huge difference. As counterintuitive as it sounds, try a higher pressure and faster rebound. Made all the difference to me. I had been running lower than recommended pressure with a bit of LSC to prevent diving, but the fork was very harsh except for big hits. Switching to a higher pressure and very little compression damping, combined with a fast rebound setting worked great. Also running just 1 token. For reference I am 175lbs, running 80PSI, open HSC and LSC, 8 clicks out LSR, 7 clicks out HSR (almost all the way open).

Thanks I'll try that out, ive heard about the excess grease. Ive never pulled a fork a part before but might have to give it a go

Agree! Beautiful bike. Super slick, real stealthy, and StUmpJumPerZ R000L!

Thanks guys pretty impressed so far. Three rides in and contrary to some of the reviews I saw it didn’t take me long to get the suspension dialed. Bike is very energetic and responsive which is what I was looking for as my other bike (Devinci Troy) leans toward the enduro end of the spectrum. Still not 100% confident on tech yet which is to be expected.

I need to figure out how to pack my SWAT box and not have a rattle box. :-)

Back from a week in the mountains, I did the ticket to ride in Lenzerheide for those who know so I ended up riding 75km of single trails, - 6000m/+1000m elevation in a day with the Stumpy. I have also ridden most of the trails from blue to black in the area.
Definitely more sporty to hold in the rough than my Decoy I also took with but still super capable, the lightweight and the pedaling capabilities were really appreciable after long days on the saddle. I didn't get any issue with the fox DPS fading (it is my first non piggy back shock ever), didn't break or overwhelmed any other part of the bike. The only think I did was to use a tougher casing in the back and performance pads.

So hade my first ride on my s4 size (alu frame so longer cs) and im 6 feet/182cm. As noob it fits me well but for an more aggressiv rider id recomend trying a s5 before deciding even tho s4 should be bang on the spot.

Pleasently suprised how natural 29 felt compared to a when trying it out a couple of years ago.

I’m still a bit hesitent on rougher patches, probably psychological thing from having less travel and geometry that says go for it it - bit mind f*ck- all in all I think we will get along well.

Nice build. This is something I'm thinking to do as well.

Anyone put a 2.6 tire on the rear? Looking to get a pair of skinwall (tan) Butcher 2.6's, but worried about clearance of a 2.6 in the rear. Anyone successful?

Had to come back and say thanks for this. I set up my fork exactly how you recommended and it feels great now. Cheers!
