Size chart and fit guide for 2026
Cannondale emphasizes proportional response sizing, where each frame size is engineered for specific rider weights and power outputs. Their SmartForm aluminum and BallisTec carbon technologies are optimized per size, ensuring consistent ride quality across the range.

Specific sizing recommendations for Cannondale's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).
Lightweight all-rounder with race geometry. Integrated cockpit may affect fit-professional fitting recommended.
Endurance bike with SAVE micro-suspension. SmartSense integration adds weight but improves safety; fit remains consistent.
Trail bike with 130mm travel. Proportional Response sizing means each size rides consistently-choose based on reach preference.
Gravel bike with Kingpin rear suspension. Unique flex pivot adds comfort; geometry is stable for mixed terrain.
Full-suspension e-MTB with Bosch Performance CX motor and 750Wh battery. 160mm travel with Proportional Response construction-each frame size is tuned for specific rider weight and power, so follow Cannondale's MTB size chart closely.
E-gravel bike with Bosch SX motor and 400Wh battery featuring Kingpin rear suspension. Gravel-tuned geometry with endurance reach-riders familiar with the acoustic Topstone should choose the same frame size for consistent drop-bar positioning.
Alloy race bike with SmartForm C1 hydroformed aluminum and a full carbon fork. Size 56 stack/reach (575/389) is identical to the carbon SuperSix EVO LAB71 at the same size, so the CAAD13 fits exactly like its carbon sibling - useful for riders who want race geometry without the carbon price. Cannondale only sells the CAAD13 in 44 to 60 cm, so very tall riders should look at the SuperSix EVO instead.
Entry-level alloy road bike with SmartForm C2 aluminum and a carbon fork. At size 56 the stack is 560 mm and reach 395 mm - slightly lower and longer than the CAAD13 at the same number, giving a more traditional aggressive fit. Trim options (Optimo 1 through 4) share identical geometry; the difference is groupset and wheels.
Flagship carbon race trim sharing the standard SuperSix EVO's Series 0 carbon layup and geometry. LAB71 is Cannondale's top-tier build line: SRAM Red AXS, HollowGram SL45 wheels, and an integrated SystemBar R-One cockpit. Size 56 numbers (575/389) match the rest of the EVO family, so an existing SuperSix rider can move to the LAB71 trim without re-fitting.
XC race full-suspension with 120 mm of travel front and rear, FlexPivot rear linkage, and Cannondale's Proportional Response carbon. The 2024 redesign added 5 mm of reach and slackened the head angle to 66.6° for modern XC race courses. Medium reach is 430 mm with a 602 mm stack. Riders moving from the older Scalpel-Si should size down or stay the same - the new geometry runs longer than the previous generation.
Enduro full-suspension with a high-pivot idler, 165 mm rear travel, and 170 mm fork. Medium fits riders roughly 162-175 cm (5'4"-5'10") with stack 630 mm and reach 455 mm. The high-pivot platform gives a rearward axle path that smooths square-edge hits but pushes the chainstay slightly longer than a Habit at the same size - riders coming from a Habit should expect a more planted, less playful feel.
Entry alloy hardtail with a 1x drivetrain, 100 mm fork, and 29" wheels (S frames run 27.5"). Medium stack/reach is 626/440 - a relatively long reach for the price point, so riders comparing against the Trek Marlin 7 (609/440 at M) should expect a similar cockpit length but a noticeably taller front end. Good first MTB for riders who plan to grow into more technical trails.
Fitness hybrid with 700×40c tires, a suspension-corrected rigid fork, and flat bars. Medium stack/reach is around 610/418 - more upright than a flat-bar Synapse but lower than the Adventure 3. Good for paved bike paths and light gravel; not built for singletrack despite the CX naming.
Comfort hybrid with a swept-back bar, padded saddle, and a very upright fit. Medium stack 626 mm and reach 362 mm puts the rider almost fully upright - made for casual neighbourhood riding, bike paths, and short commutes where speed isn't the priority. The Adventure EQ trim adds fenders and a rear rack on the same frame.
Mahle X35 hub-motor e-commuter with 250 Wh internal battery, 650b wheels and 50 mm balloon tires. Medium frame fits 5'4" to 6'0" (162-183 cm) with stack 580 mm and reach 379 mm - relaxed but more sporty than the Adventure thanks to the lower stack. Single-speed assist makes the riding feel like a regular bike with a tailwind rather than a pedelec.
Bosch Performance Line CX trekking e-bike with rear rack, lights, and fenders included from the factory. Diamond-frame medium stack/reach is 629/430. Riders who want easier mount-and-dismount should look at the Tesoro Neo X Remixte (low step-through) - geometry is slightly different on that frame. Class 3 (28 mph assist) in the US.
Cannondale's kids' MTB-style line in 16-inch (riders 41"-49"), 20-inch (riders 45"-53"), and 24-inch (riders 51"-59") wheel sizes. Lightweight 6061 aluminum frame, single-speed coaster or 6-speed grip shift depending on size. Low standover and a confidence-inspiring fit for kids 4-10 learning trails.
