Which is better, the Trek Émonda SLR or the Cannondale SuperSix EVO?

Both are excellent road bikes. The Trek Émonda SLR and Cannondale SuperSix EVO excel in different areas - sizing, geometry, and riding style all factor in. Use our side-by-side comparison above to see which fits your body measurements and riding goals.

How do Trek and Cannondale sizing compare?

Trek and Cannondale use different sizing systems. A medium in one brand may not match a medium in the other. Always check the specific size chart for each model and compare stack, reach, and standover height for the best fit.

Is the Trek Émonda SLR good for beginners?

The Trek Émonda SLR can work for beginners depending on the specific build and geometry. Consider factors like stack height (upright vs aggressive), standover clearance, and tire clearance. Our bike size calculator can help determine if it's the right fit for your measurements.

What size Cannondale SuperSix EVO should I get?

The right size depends on your height and inseam measurement. Use our bike size calculator with your measurements, then cross-reference with the Cannondale size chart to find your ideal frame size for the SuperSix EVO.

Can I use the same size in both Trek and Cannondale?

Not necessarily. Even within the same size label (e.g., "Medium"), Trek and Cannondale frames may have different effective top tube lengths, reach, and stack measurements. Always compare the geometry tables rather than relying on size labels alone.

Road Bike

Trek Émonda SLR vs Cannondale SuperSix EVO

The classic American lightweight versus the American all-rounder. The Trek Émonda SLR is the lightest frame Trek has ever built - OCLV 800 carbon, sub-700 g, race geometry. The Cannondale SuperSix EVO went the other direction in 2023 and reinvented itself as an aero race bike that still climbs. They overlap in price and intent, but the on-paper personalities pull apart: pure climber versus aero all-rounder. Most race calendars favour the SuperSix today. Mountain weekends still favour the Émonda.

Side-by-Side Overview

Trek Émonda SLR

$6,500 - $13,000

Best for: Climbers and lightweight specialists who care about every gram on long ascents

Strengths

•OCLV 800 frame around 690 g - the lightest production frame in Trek's range
•Eight sizes (47-62 cm) cover riders from about 5'0" to 6'5"
•Project One custom paint program
•H1.5 race geometry is aggressive but not extreme - rideable for long days
•Trek's US dealer network is the largest in cycling

Considerations

•Less aero than the redesigned SuperSix EVO at any speed above 30 km/h
•Tire clearance 32 mm matches the SuperSix but lags newer all-rounders
•BB90 press-fit shell has a polarising service history
•Integrated RCS Pro cockpit on top trims raises long-term fit cost

Cannondale SuperSix EVO

$3,500 - $13,000

Best for: All-around racers who want one bike for crits, road races, and fast Sunday rides

Strengths

•2023 redesign added genuine aero gains while keeping climbing manners
•Seven sizes (44-61 cm) including a true 44 for smaller riders
•Frame weight around 770 g - heavier than Émonda but aero offsets it above 30 km/h
•Entry-level Carbon trims start at $3,500, well under the cheapest Émonda SLR
•Hidden seatpost wedge and dropped seatstays give a distinctive look

Considerations

•Aero gains add weight - not the right bike for hill climb specialists
•Cannondale's dealer network has thinned in some US markets
•Proprietary HollowGram cockpit on top builds limits stem swaps
•Long, low front end can feel cramped for riders with shorter torsos

Geometry Comparison Chart

Sizing Comparison

At the 54 mark, the SuperSix runs a lower stack (527 vs 537) and longer reach (388 vs 383) than the Émonda - a more aggressive front end at the same nominal size. Riders coming from an Émonda 54 will want to consider the SuperSix 56 (559/392) for a comparable cockpit height, or stay at 54 and add spacers. At the small end, the SuperSix 44 (489/376) is the most aggressive frame either brand offers - genuinely race-only. The Émonda's 50 (521/376) is a more forgiving small-frame option.

Verdict

Buy the Cannondale SuperSix EVO if your races are flat or rolling and your group rides hover above 30 km/h - the aero gains compound over a season and the entry price is thousands lower than the cheapest Émonda SLR. Buy the Trek Émonda SLR if you climb a lot, count grams, or want Trek's dealer safety net and Project One paint. The Émonda is the better climber by a noticeable margin. The SuperSix is the better all-rounder by a similar one. They are not really the same bike anymore.
