Sizing a Cube road bike
Cube labels its road frames in centimetres rather than letters, and the range runs from the aero Litening to the sporty Agree and the comfort focused Attain. The pattern owners report most is that Cube comes up long: the top tube and reach feel generous for the size, so between two sizes the usual advice, and Cube's own, is to take the smaller. On the aero Litening, the one piece cockpit also fixes your bar and stem, so it pays to pick the size whose stock cockpit suits you.

Please note. These sizes are a starting point, not a guarantee. Cube does not publish a distinct per size height table per model, so the ranges here map its general road chart onto each model's cm sizes and can move ± a size with your proportions. A fit check settles any doubt.
Quick size finder
Find your height, cross check your inside leg, and read across to the cm size. The Litening runs 50 to 60, while the Agree and Attain run 47 to 62.
| Rider height | Leg length (inseam) | Litening Aero C:68X | Agree C:62 | Attain |
|---|---|---|---|---|
| 152 to 160 cm | 71 to 76 cm | — | 47 | 47 |
| 160 to 168 cm | 75 to 80 cm | 50 | 50 | 50 |
| 168 to 175 cm | 79 to 84 cm | 54 | 53 | 53 |
| 175 to 182 cm | 83 to 88 cm | 56 | 56 | 56 |
| 181 to 188 cm | 87 to 91 cm | 58 | 58 | 58 |
| 187 to 193 cm | 90 to 94 cm | 60 | 60 | 60 |
| 192 to 200 cm | 94 to 99 cm | 60 (max) | 62 | 62 |
The Litening also comes in a 52 that slots between the 50 and 54, useful right on the boundary. Because Cube comes up long, lean to the smaller size if you are between two.
How to measure yourself
Height. Stand barefoot against a wall, heels together, and measure to the top of your head.
Leg length (inseam). Barefoot, feet about 15 cm apart, press a book up to the wall like a saddle and measure floor to spine.
The reliable check. Compare the stack and reach below with a bike that already fits you. On a brand that comes up long, that comparison is more trustworthy than the cm number, and it flags whether to size down.
The current road range, model by model
Litening Aero C:68X (aero race)
The Litening is the aero racer, but more upright and climbable than its looks suggest rather than fully slammed. Its one piece cockpit fixes bar and stem, so choose the size whose stock cockpit fits. Available in 6 sizes: 50, 52, 54, 56, 58 and 60.
| Frame size | 50 | 52 | 54 | 56 | 58 | 60 |
|---|---|---|---|---|---|---|
| Stack (mm) | 514 | 524 | 542 | 563 | 580 | 594 |
| Reach (mm) | 389 | 389 | 389 | 398 | 403 | 405 |
| Rider height | 160 to 168 | 165 to 172 | 170 to 177 | 175 to 183 | 181 to 189 | 187 to 196 |
The three smallest sizes share a 389 mm reach, differentiated by stack and the size specific cockpit, so choose by stack and cockpit fit down there. It is an unusual figure worth confirming on the exact bike.
Agree C:62 (endurance race)
The Agree is the sporty middle ground, racier than most endurance bikes but with a calmer front end than the Litening. Owners note it runs long, so size down if unsure. Available in 7 sizes: 47, 50, 53, 56, 58, 60 and 62.
| Frame size | 47 | 50 | 53 | 56 | 58 | 60 | 62 |
|---|---|---|---|---|---|---|---|
| Stack (mm) | 513 | 523 | 543 | 572 | 591 | 606 | 628 |
| Reach (mm) | 376 | 378 | 383 | 391 | 394 | 399 | 402 |
| Rider height | 152 to 160 | 160 to 168 | 168 to 175 | 175 to 182 | 181 to 188 | 187 to 193 | 192 to 200 |
Attain (endurance)
The Attain is the relaxed, upright endurance bike, with a tall stack and short reach for all day comfort. Figures below are the carbon Attain C:62; the alloy Attain shares the stack but has a slightly longer reach, so rides a touch less upright. Available in 7 sizes: 47, 50, 53, 56, 58, 60 and 62.
| Frame size | 47 | 50 | 53 | 56 | 58 | 60 | 62 |
|---|---|---|---|---|---|---|---|
| Stack (mm) | 525 | 538 | 561 | 591 | 610 | 629 | 648 |
| Reach (mm) | 365 | 369 | 376 | 385 | 388 | 392 | 391 |
| Rider height | 152 to 160 | 160 to 168 | 168 to 175 | 175 to 182 | 181 to 188 | 187 to 193 | 192 to 200 |
The carbon C:62 has a shorter reach than the alloy Attain, so it rides even more upright. Cross shoppers between the two should not assume identical fit at the same cm size.
What Cube riders find
The recurring owner note is that Cube road bikes come up long in the top tube and reach, most obviously on the Agree, so the community and Cube itself advise taking the smaller size when between two. The Attain delivers a genuinely relaxed, back friendly position and is praised as strong value, with the carbon version sitting more upright than the alloy at the same size. The Litening is more upright than its aero styling implies and its reach feels natural in practice, but its integrated cockpit makes later bar and stem changes expensive, so choose the size with the stock cockpit in mind. Cube's own online calculator tends to nudge in between riders to the larger option, which is worth weighing against the runs long feedback.
Between two sizes?
Go smaller for a sharper, racier fit, which suits Cube's long cockpits, or larger only if you want maximum stack and stability. On the Litening, let stack and the fixed cockpit guide you. Send us your height, inside leg and current reach and we will confirm.

Cube's cm sizing and long cockpits make this a good one to check. Share your height, inside leg and the reach of your current bike and our concierge team will recommend the right size. Talk to our concierge.
These sizes are guidance, not a fitting guarantee. Stack and reach are current Cube data; the Litening's three smallest sizes share a 389 mm reach, which is unusual and worth confirming on the exact bike, and the Attain differs between carbon and alloy. Rider height ranges map Cube's general road chart onto each model, so confirm against the specific bike you are buying.
