Lightest oem trail bikes in 2024?

[RocketRacing]

short version: what are the modern, oem, lightest trail bikes these days? 140/140+ please. the one i am eyeballing is the 2024 occam sl at 24lbs and 140/140. i dont need much more where i live/ride.

so i race xc, and as a 60kg rider, i am pretty focused on light bikes... cause as a small rider, bike weight means statistically more to my performance as it is a larger part of my total system weight.

now, i also see the value in droppers, slack geo, wider tires, and 120mm suspension in xc cause in the end of the day my goal is speed... and i know damn well that weight is pretty low on the totum pole of speed importance in mtb.

so what i race is a 2024 orbea oiz sitting at 22lbs ready to ride. the idea was to get one light/nice dual sus xc bike with three way suspension... vs a hardtail and dualie.

but some non xc races have me wanting to push a bit more. the orbea occam sl trail bike seems like the next step at 140/140 and 24lbs (with cheater tires, but with a few parts swaps 24 is a realistic goal).

what other light options do i have? and a (beefed up) oiz vs occam video doing an enduro race made me think twice about just beefing up my oiz.

What's a trail bike to you? Travel is only one measure. The ISO ATSM testing category is another https://www.dtswiss.com/en/support/astm-classification

The difference in weight between an XC bike and lightweight Trail bike is like:
1) Tire - 200gr / tire super light XC vs similar knobby high-performance trail.
2) Suspension - 100gr Shock + 200gr Fork
3) Frame - 600gr (epic evo vs Stumpy)
4) Wheels - 75gr (DT Swiss AL)
5) Seat post - 100gr (100mm vs long travel)

The base category (XC vs Trail) is going to inform how the bike is going to pedal vs handle small bumps. If you're not going to be bombing down trails, you can get one of the more trail/long travel orientated downcountry bikes (YT Izzo, Transition Spur, BC140, Revel Ranger, Canyon Neuron) and save about ~600gr there and with the rear shock. Otherwise, the folks who have the lightest XC bikes are going to have the lightest trail bikes. You're probably better served getting a bike that's more distanced from your current XC bike.

as a "newer" rider i am building skills and expanding my riding risk slowly. locally is mostly xc, but i have options for big stuff also. the sl feels very close to my oiz, but it is a step up for sure. the lt would add a lot of safety margin, but have less use in day to day riding.

That's oddly light for a 140/140 bike. My trail bike is a '23 Spark Ultimate with drivetrain swap to drop weight. This is the lightest or one of the lightest 120mm frames and I can't see anywhere else to shave weight without going to full XC components*. It's 23.8lbs. That's usually shocking to people and a couple pounds lighter than other light trail bikes like my wife's Spark or friend's $$$ Ripley build.

Even if the "24lbs" is without pedals (so really 25lbs) that's impressive. If I could add 20mm in the rear and 10mm up front for only a pound I'd take it. However, it already feels like I'm pushing the wheels and tires to their limit, so with more travel I might need to beef those up. This makes me really question how well set up a 24lb 140/140 bike is.

*Okay, I could swap the XX1 crank out for a Clavicula and lose 1/4lb.

i look at it as a slacker oiz (67 vs 65.5)with 20mm extra travel. has a lot of weight weenie stuff and super race casing tires which is funny... so imho you need a swap right out of the box which will add one poind also. realistically it is a 26lbs bike. i could make it 25 i bet without compromising tires.

Not technically a "trail bike" but Epic Evo is under 10kg and exceptionally capable if you use the right tires. The AXS dropper is a heavy luxury item and if you could forego that for a regular dropper it would save even more weight.
