This sizing guide helps you find your ideal Scott Addict RC.

The Scott Addict RC (Racing Concept) is an all-rounder race bike. According to Scott,

The new Addict RC employs a race geometry that caters to professional and amateur cyclists who prefer a more aggressive position and a very direct handling bike. This geometry was developed in close collaboration with professional cyclists at Mitchelton-Scott and renowned bike fitters at Radlabor.

There are seven frame sizes available for cyclists with heights from 5’1″ to 6’7″ (156 to 200cm).

The chart above is just a starting point. There’s more to a good fit than height beyond the sizing chart. 

Scott sizing vs. other brands

Scott bikes come in XXS, XS, S, M, L, XL, and XXL sizes.

These provide a rough indication of the frame size. However, they may not be consistent across other bike brands. What constitutes a size S in a Scott could be different in another brand that uses a similar sizing, such as Giant.

Just relying on these values alone can be misleading.

Understand the stack and reach measurements 

If you have a bike that fits you well and is comfortable, use that as a reference point. 

Find out its Stack and Reach measurements and compare them against the Scott Addict RC’s measurements. Then, pick the closest size.

  • Stack is the vertical distance from the bottom bracket to the top of the head tube. Stack height influences how high your handlebars will be relative to your saddle. A higher stack leads to a more upright riding position, which can be more comfortable, especially for longer rides, older riders, and those with less flexibility on the lower back.
  • Reach is the horizontal distance from the bottom bracket to the center of the head tube. It determines how stretched or compact your riding position will be. A longer reach results in a more stretched-out, aggressive riding posture, while a shorter reach promotes a more upright position.

The Stack and Reach measurements can be found below.

Size up or down?

The Scott Addict RC’s sizing chart has overlapping height limits, similar to most bike brands. So, it’s not unusual to find yourself torn between two sizes.

If you’re facing this predicament, there are many things to consider, such as your legs-to-torso proportions and the final look of the bike, taking into consideration the number of spacers, stem length, and the amount of exposed seatpost.

Having said that, I’d recommend sizing down (choose the smaller size) for most cyclists.

There is more room to correct a smaller bike than a bigger one. The smaller frame has more room to extend reach, and increase stack. Nonetheless, there is a boundary to these corrective measures to avoid having too many spacers (30mm+) or too much exposed seatpost, which makes the bike look out of proportion.

The smaller frame is also stiffer, more maneuverable, and marginally lighter. If set up right, it’ll have more exposed seatpost, leading to more comfort due to increased seatpost flex.

If you have an average legs-to-torso proportion, opting for the smaller size would be a better option.

  • If you have longer legs with a shorter torso, consider sizing up to avoid having too much exposed seatpost.
  • If you have short legs with a longer torso, consider sizing down and using a longer stem to extend reach.

Test ride before you buy

No amount of advice compares to the insights from a test ride. I’ve always advocated getting a feel of the bike and understanding its nuances. Visit a local Scott dealer, try multiple sizes, speak to the salesperson, and trust your instincts.
