If you’re wondering what size Tarmac SL7 should I get, you’re not alone. Choosing the right frame size is one of the most important steps before investing in this high-performance bike. The Specialized Tarmac SL7 is engineered to deliver pro-level speed and precision, but you’ll only unlock its full potential if the fit matches your height, proportions, and riding style. Let’s break down exactly how to find your perfect size — and what to look for before you buy.
Why Size Matters for the Tarmac SL7
The Tarmac SL7 is built with aggressive race geometry. That means every frame size changes how the bike feels — from its responsiveness in corners to comfort on long rides. A frame that’s too big will feel stretched and unstable; one that’s too small can make you cramped and limit power output. Getting it right ensures optimal aerodynamics, comfort, and efficiency — the three key pillars of the Tarmac’s design.
Specialized Tarmac SL7 Size Chart
Specialized offers the Tarmac SL7 in seven sizes, from 44cm to 61cm. Here’s a simplified guide to help you match your height to the right frame:
| Rider Height (ft/in) | Rider Height (cm) | Recommended Frame Size |
|---|---|---|
| 4'8" – 5'1" | 142 – 155 cm | 44 cm |
| 5'1" – 5'4" | 155 – 163 cm | 49 cm |
| 5'4" – 5'7" | 163 – 170 cm | 52 cm |
| 5'7" – 5'9" | 170 – 175 cm | 54 cm |
| 5'9" – 5'11" | 175 – 180 cm | 56 cm |
| 5'11" – 6'2" | 180 – 188 cm | 58 cm |
| 6'2" – 6'5" | 188 – 196 cm | 61 cm |
Tip: If you fall between two sizes, go smaller if you prefer a more aggressive position or larger if you prioritize comfort and stability.
How to Measure Yourself for a Perfect Fit
1. Measure Your Inseam
Stand barefoot with your legs slightly apart. Measure from the floor to your crotch. Multiply that number (in centimeters) by 0.67 to get your approximate frame size in cm. Compare it to the chart above for confirmation.
2. Consider Reach and Stack
The Tarmac SL7 features Rider-First Engineered™ geometry, meaning the frame’s reach (horizontal length) and stack (vertical height) are optimized per size. Riders with shorter torsos might prefer smaller frames for better control, while those with longer arms may benefit from a larger one.
3. Professional Bike Fit
For the most accurate sizing, consider a professional fit. Shops that sell the Tarmac SL7 often use body geometry fit systems to match your flexibility, proportions, and riding goals to the ideal size.
What Makes Sizing Different on the Tarmac SL7
Unlike endurance bikes, the Tarmac SL7’s geometry puts riders in a race-oriented position. The head tube is shorter, and the stack height is lower, which helps reduce drag and improve power transfer. Because of that, riders coming from endurance bikes (like the Specialized Roubaix) may prefer to size up for comfort or use spacers to raise the handlebar height.
Signs You Have the Wrong Size
- You feel overstretched or hunched over excessively.
- Your knees hit the handlebars when pedaling.
- The bike feels twitchy or unstable at high speed.
- You experience neck, back, or shoulder discomfort on longer rides.
Final Verdict
So, what size Tarmac SL7 should I get? The answer depends on your height, proportions, and riding style — but the chart above provides an excellent starting point. The Tarmac SL7 is engineered for precision, so even small differences in frame size can dramatically change how it feels. If you’re between sizes, test both if possible. When the fit is right, the SL7 transforms every ride into pure speed, control, and efficiency — exactly what it was designed for.
FAQs
1. Does the Tarmac SL7 run small or large?
The Tarmac SL7 fits true to size compared to other race bikes. However, its aggressive geometry may feel smaller if you’re used to endurance bikes.
2. Should I size up or down if I’m between two sizes?
If you want a more aerodynamic and aggressive position, go smaller. If you prefer stability and comfort, size up.
3. Can I adjust the fit after choosing a size?
Yes. Minor adjustments like stem length, saddle height, and handlebar stack can fine-tune your fit for comfort and efficiency.
