Levo Gen 4 Spez Levo 4 Comp Alloy

[Chubba]

Hey All,

Looking for upgrade advice on my 2026 Specialized Turbo Levo 4 Comp Alloy.

Bike spec highlights:

• Levo 4 Comp Alloy
• 105Nm / 810W motor
• 840Wh battery
• Fox 36 Rhythm fork
• Fox Float X Performance GENIE rear shock
• SRAM Eagle 90 T-Type drivetrain
• SRAM Maven Bronze brakes
• Mullet setup (29 front / 27.5 rear)
• Bike is already running tubeless

I've been reading a lot of forum discussions and would like opinions from people who have spent time on the Levo 4 platform.

The common feedback seems to be that the Fox 36 Rhythm is the weakest component on the Comp Alloy build.

Potential upgrade path I'm considering:

1. Fork upgrade

• Fox 38 Factory GRIP X2
• Fox 38 Performance Elite
• RockShox ZEB Ultimate

1. Rear shock
   The bike currently has the Fox Float X Performance GENIE shock.

Would you do:

• Keep it as is?
• Upgrade to a Fox Float X Factory?
• Upgrade to a Fox Float X2 Factory?
• Upgrade to a RockShox Vivid Ultimate?

How much real-world improvement would I see?

1. Rear wheel protection

• CushCore Pro?
• CushCore Trail?
• Tannus?
• Other inserts?

Running Butcher tyres currently.

1. Contact points

• OneUp Carbon Bar
• Renthal FatBar Carbon

Have these made a noticeable difference on your Levo?

1. Wheels
   Longer term:

• Reserve
• We Are One
• DT Swiss EXC / HXC
• Roval

Would wheels be a worthwhile upgrade before touching the rear shock?

The main question:

If this was your Levo 4 Comp Alloy and you had a reasonable upgrade budget, what would be your first three upgrades and why?

Interested in feedback from riders who have actually owned or ridden both the Fox 36 Rhythm and Fox 38 / ZEB on the Levo 4.

What components feel like they’re holding you back?

Time time ask yourself…..not us

What is YOUR Riding………
Style?
Skill level?
Terrain?
Budget?

You’ll get more adjustments, smoother internals as you spend more money.
Most people won’t/dont use these much at all. Hint ……you won’t

So unless you adjust clickers regularly to improve trail handling, and/or blow through stock travel (after adding tokens, and properly setting up your suspension)
Seems your upgrade path may follow your budget….

Get what you can afford.

I bought the bike I could afford at the time, have budget to upgrade a few components. I ride technical, rocky, rooty and gravelly single track, big climbing and fast downhills. I would say I’m an intermediate rider, been riding tech stuff for 30 years. I guess I’m trying to get a feel for what others have upgraded. I don’t rate the rhythm fork, 38 fox factory or zeb is something I’ve been looking at. Happy for feedback on this. Also find the wheels and hubs cheap, so would consider upgrading these.

Shock is good, brakes and groupset are solid.

I’m coming off a Levo 2 which was a fantastic bike.

those are both fine choices.
Does one have HBO, if you send it good once in awhile, HBO is pretty pretty pretty nice
There’s also service in your area. Does one fork have better LBS support? Can you service one at home vs shop.
After much research I went 170/170 Podium/CC link, on my Levo . I built it for no compromise steep AF PNW descents, built it before the new one was released. I don’t really care about climbing geo.
I was blowing through stock travel and had to put pressures so high to prevent bottoming, I lost sensitivity. 170mm seemed to be enough for me once it was dialed with tokens.
If I get a new fork now, it will have HBO.
