Sizing a Guerciotti gravel bike
Guerciotti is a small, characterful Milanese marque, and its gravel range runs from the carbon Escape and new flagship Anima to the comfort minded Brera and the value alloy Greto S. Being a boutique builder, Guerciotti publishes very little sizing data: there is no official rider height chart, and the geometry tables on the site are images rather than figures. So this guide leans on the numbers we could verify and is honest about where we could not. The theme across the range is a fairly low, short reach, race leaning fit, which means comfort seekers often size down or add spacers.

Please read. Guerciotti publishes no official height ranges for gravel, so every height band here is our estimate from geometry, and some model figures are proxies from the closest available generation. Treat this as a first pass and confirm with us or a fitter, especially since Guerciotti sells through dealers and offers customisation.
Quick size finder
Find your height, cross check your inside leg, and read across. The carbon Escape and Brera run XS to XL; the alloy Greto S offers the widest range, XXS to XXL.
| Rider height | Leg length (inseam) | Escape & Brera | Greto S |
|---|---|---|---|
| 152 to 160 cm | 71 to 76 cm | — | XXS |
| 158 to 166 cm | 74 to 79 cm | XS | XS |
| 165 to 174 cm | 78 to 83 cm | S | S |
| 172 to 181 cm | 81 to 86 cm | M | M |
| 178 to 187 cm | 84 to 90 cm | L | L |
| 185 to 195 cm | 89 to 95 cm | XL | XL |
| 190 to 198 cm | 93 to 98 cm | (XL max) | XXL |
Only the Greto S covers riders under about 160 cm and over about 190 cm well. Because the fit runs low and short, comfort focused riders can size down and add spacers.
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. With so little published data, the safest route is to match the reach below to a bike you ride well, and to talk to us or a Guerciotti dealer, since they offer fit customisation.
The current gravel range
Escape (carbon, performance)
The Escape is the carbon performance gravel bike, stiff and reactive with a road crossover feel, offered in two rear ends for wider or narrower tyres. Its low stack and moderate reach make it the sportiest handling of the range. Available in 5 sizes: XS, S, M, L and XL.
| Frame size | XS | S | M | L | XL |
|---|---|---|---|---|---|
| Stack (mm) | 534 | 553 | 564 | 584 | 602 |
| Reach (mm) | 368 | 376 | 378 | 382 | 391 |
| Rider height | 158 to 168 | 166 to 174 | 173 to 181 | 179 to 187 | 185 to 195 |
These are verified Escape figures. Best for riders coming from a road bike who want speed off road.
Brera (carbon, comfort)
The Brera is the comfort and performance gravel bike, a little taller in stack and shorter in reach than the Escape for a more upright, all day and bikepacking friendly position. Available in 5 sizes: XS, S, M, L and XL.
| Frame size | XS | S | M | L | XL |
|---|---|---|---|---|---|
| Stack (mm) | 538 | 556 | 568 | 589 | 606 |
| Reach (mm) | 376 | 376 | 377 | 380 | 384 |
| Rider height | 158 to 168 | 166 to 174 | 173 to 181 | 179 to 187 | 185 to 195 |
These figures are from the previous generation Brera. The 2026 frame was redesigned with more tyre clearance, so treat the numbers as a close proxy and confirm on the exact bike.
Greto S (aluminium, value)
The Greto S is the value alloy all rounder, redesigned toward comfort, with integrated cables and the widest size range. It is the pick for the smallest and tallest riders. Available in up to 7 sizes: XXS to XXL.
| Frame size | XXS | XS | S | M | L | XL |
|---|---|---|---|---|---|---|
| Stack (mm) | 509 | 509 | 523 | 535 | 546 | 557 |
| Reach (mm) | 363 | 378 | 385 | 387 | 388 | 395 |
| Rider height | 152 to 160 | 158 to 166 | 165 to 173 | 171 to 179 | 177 to 185 | 183 to 191 |
These are from the outgoing Greto, the closest data available; the Greto S geometry was revised toward comfort, so expect slightly more stack. A separate XXL exists for the tallest riders. Confirm figures on the exact bike.
Anima (carbon flagship)
The Anima is Guerciotti's new for 2026 flagship gravel racer, the lightest and stiffest in the range and positioned as the most aggressive fit. Guerciotti has not yet published its geometry, so we cannot give reach figures here. If the Anima is on your shortlist, size by rider height as a starting point and talk to us to confirm.
What Guerciotti riders find
Independent owner feedback on Guerciotti gravel is very thin, as befits a small marque, so we are cautious about claiming sizing quirks. What we can say from geometry and positioning is that the range fits true to size to slightly aggressive: the Escape is the stiff, reactive, road crossover racer; the Brera is the more upright, comfort biased all rounder; the Greto S is the comfortable value alloy option with the broadest size range; and the Anima is the uncompromising race flagship. Because stack is low and reach short and fairly constant across sizes, riders wanting an upright endurance position tend to want the next size down or extra headset spacers. Guerciotti sells largely through dealers and test centres and offers customisation, so a fit consultation is the reliable path.
Between two sizes?
Go smaller for a racier reach or to sit more upright with spacers, larger for more reach if you want it stretched. Given how little Guerciotti publishes, matching the reach of a bike you love is the safest method, so send us that number with your height and inside leg and we will help.

These sizes are good faith estimates, not a fitting guarantee.
