By cutting hardware weight in half, rerouting cables more efficiently, and minimizing individually-molded frame pieces, the 2023 Scott Scale RC sheds a lot of weight and introduces some clever new design features.
Designed for those days when Nino Schurter and Kate Courtney don’t need a full suspension bike, the new Scale gets modernized (and adjustable) geometry and fork suspension travel, and yet still comes in lighter than ever…
How Scott saved weight on the new Scale HMX-SL
The 2023 Scott Scale comes in three different levels of carbon frames and a heavily sculpted alloy frame that shares much of the same laborious process used to shape the gorgeous alloy Genius trail bikes.
Naturally, the most extreme weight savings comes on the top model, the Scale HMX SL, and those weight savings come in several ingenious ways.
New hollow dropouts save 7.5g directly, and allow for a total 20-gram savings in the general area because it’s slimmer overall.
The design eliminates the outer structure where the thru-axle enters the non-drive side, letting it clamp directly against the inner wall. A floating washer around the axle’s head prevents damage to the frame. Not only does this save weight, it’s also completely flush.
Streamlined rear brake mounts save another 14g.
The chain guide sits flush with the frame, which looks clean and saves a bit of weight, too. When not in use, it can be removed, as can the threaded insert on the inside of the frame, and plugged to save more weight.
That insert is accessed through a downtube port that also eases internal brake hose routing and general maintenance.
Polymer inserts for bottle cage mounts replace in-molded or bonded metal inserts. This allows for smooth, flush inserts to be used for a cleaner look where the mounts won’t be used, or clip in the polymer mounts (no tools needed) when you want a bottle cage. And those parts are all replaceable should they ever break or get lost.
In total, hardware weight was cut in half, from 82g down to 45g.
The new construction uses a monocoque (single-piece) construction for each section of the frame, and there are only two sections – the Stiffness Zone and the Lightweight Zone.
The lower half of the bike is where all of the torque and bending forces are applied, so that was created as a single piece to maximize strength and stiffness by eliminating joints and optimizing the carbon fibers throughout. Fewer joints means less overwrap, which means less weight.
That let them make the top half lighter (and, with flat stays and clearance for 29×2.4″ tires, presumably a bit more compliant).
Here’s how they compare to prior models:
Other features of the 2023 Scott Scale RC
The rear brake hose and any rear shifter and dropper cables run internally, ported through the headset and a custom spacer, but there’s a trick up their sleeve…
An adjustable headset cup lets them adjust the head angle by 0.6º, which was used to allow them to run 100mm or 110mm suspension forks without affecting handling…but it can do that, too.
To swap, simply loosen and lift the stem, rotate the upper headset cap 180º, reinsert and reinstall everything, and it’s ready to ride. No need to remove any cables or hoses to make the adjustment.
Paired with their Fraser iC one-piece bar/stem, it makes for a very clean cockpit on the top-level bikes.
And they offer various mounts that attach underneath the bar to mount cycling computers, lights, action cams, etc.

2023 Scott Scale RC Models
In total there are 24 different Scott models with the top-level Scale RC frame (from $3,499 to $13,999, but not all are the “SL” version), plus more with standard carbon fiber and alloy frames ($1,599 to $2,999), including four Contessa women’s specific models. Here are a few highlights, check their website for the full catalog.
Above is the Scale RC SL with HMX SL frame, Fox 32SC 100mm fork, SRAM XX1 Eagle AXS with power meter, Trickstuff Piccola brakes, and Syncros full-carbon SL wheels for $13,999, and a claimed 8.9kg / 19.62lb complete bike weight.
The Scott Contessa Scale lineup gets women’s specific components and unique colors, and some models and builds are not available in every market (this one shown above doesn’t show up on the U.S. site at time of publication).
The Scott Scale 910 gets the base-level carbon fiber for a more affordable option, but still a decent build. Scott’s naming hierarchy puts “RC” at the top, then 900-series numbers where a lower number (“910”) indicates a higher end build, and a higher number (“970”) is a lower end, more affordable bike.
The alloy Scales come in plenty of build options, with a nearly all-white Contessa model with stealth graphics (not the one shown here).
A heavily hydroformed frame shows that Scott’s engineers put plenty of engineering effort and attention to detail in their more affordable models, too.
