Anyone running the OneUp 240mm dropper yet? Oneup's calculator puts me and my S4 on the fence between a 210 or a 240 shimmed down to 220/230 and I really don't know which to choose to get the most slam out of my seat.

It's listed as 47mm deeper than my PNW 200 which is bottomed out in my S5, so for my 31" saddle to bb height, there's clearly no way I could make that work. If you're dealing with a 33" saddle height or higher, you should be fine, well after adjusting for the 20mm shorter insert length for the S4, you'd actually need to be closer to 34" from bb to top of the saddle.

What's your distance from bb to seat-rails in cm?

anyone use a 51mm offset fork? the shop that is building my bike is out of 44mm offset 36 forks but they do have 51mm. any thoughts on how this might effect the bike? also would a 38 in 160 or 170 be over kill?

Specialized (and basically all other modern-geo MTB manufacturers) spec's these with 44mm offset (42mm for Rock Shox) secondary to achieving more trail by running 29" wheels and slacker HTA's, all of this improves high speed stability. In short, lower fork offsets increase trail. And increasing fork offsets reduce trail.

Fun fact, smaller wheels have much less stability at higher speeds. This is why Rock Shox offers a 38mm offset to improve high speed stability for the 27.5" crowd.

For the SJ Evo, If you want to improve low speed stability and maneuverability, just swap the adjustable headset cup into the steep setting, this will effectively reduce trail and HTA, providing a noticeable improvement in low speed performance.

Has anyone here directly compared the 21' - 22' Evo Expert vs a Hightower? I'm between these two. Also it seems the STJ has real frame cracking issues?

No, the SJ does not issues. A few hard hitters running too much sag went mach-chicken into rock gardens. Those pictures hit a few forums and word spreads like wildfire. If you are skeptical, just add a piece of thin malleable foam under the factory bolt-on rock guard. Frankly, with my own eyes I have seen far more Santa Cruz triangles replaced than I've ever seen from Specialized.

My advice to preventing frame cracks: 99.75% of us are not sponsored professional riders, we don't need to ride like we are against the clock. Walk the trail sections, remove loose rocks and debris, find a good line or two, and then ride the section.

The hightower is a great bike, no doubt. But the specialized ticks all the boxes. Climbs better, can run a coil shock (no interference from frame), internal frame storage, much more adjustable geometry.

I’m not sure I have ever heard that the stumpjumper is a good climber

You don't buy a SJ Evo for its climbing prowess, but I will tell you from personal experience, it climbs just as good as my 2020 Tallboy ever did. VPP is nothing to write home about...

Having had both a HT2 and a '21 Stumpjumper Evo, I thought the Evo climbed better than the Hightower. I like the more solid and beefy frame on the Santa Cruz but never had any issues with the Evo frame and I rode it proper all over Utah, Idaho, and Wyoming.

What do you ride now ?

It also depends what you mean with ‘a good climber’. With the shock open, the evo seems more focused on traction than pure efficiency. It’s more a question of preference, but the evo is by no means a pig on the uphills.

If you use the climb switch, the evo doesn’t bob at all. So for longer climbs, it’s as efficient as any other bike in this category.

Coming from a '19 Sentinel, the '21 SJ Evo climbs like a goat. There are definitely better bikes out there if all you are doing is climbing but the SJ Evo also rips. So......

I've got a Spur and just finished building a '21 Stumpjumper with the flex stays. Pretty similar bikes but the Spur just isnt enough bike for what i want everyday, and i missed the SWAT storage.

Anyone changed the bearings on a carbon stumpy evo yet? Looking for advice on how to remove the double row bearings in the chainstay with the spacer inbetween. Do they both come out from one side?

Also, I cant access the main pivot bearings as the internal cable guide hose prevent the chainstay from being moved away from the front triangle.

Finally got mine built up... need to break out the real camera to get some beauty shots.... but went for a ride instead... needs a few tweaks here and there (trim the lines, tighten the XT clutch), but otherwise, I dig it. SWAT really is a game changer, and this thing makes me feel like an enduro racer.

Hi all, I've only had 2 rides on my new ST evo and loving it. The SWAT storage is amazing...but my SWAT bag or tools in the bag rattle like mad when things get bumpy. Has anyone had the same issues, and any tips to silence it? I put my CO2 cartridge and levers in a soft tool bag, and then put them in the SWAT bag, but it almost seems like it's the bag that is rattling in the downtube.

Yeah I shoved a car sponge up there. Running 2 swat bags though so you might need 2 sponges!
