Almost — but not quite. The Allez Sprint borrows its geometry from the previous-generation Tarmac SL7, not the current SL8. Compared to the SL8 at the same numerical size, the Allez Sprint sits taller in stack and shorter in reach with a slacker head tube — a touch more upright, a touch slower-steering.

In-platform, both bikes feel like race bikes. Cross-shopping, the SL8 places you noticeably lower and more aggressive.

The Allez Sprint Comp build weighs 8.68 kg (size 56) versus 7.77 kg for the Tarmac SL8 Comp at the same size — about a 900 g difference for the entry builds. Step up to a Tarmac SL8 Pro and the gap widens to roughly 1.4 kg.

On a 30-minute climb, that's worth somewhere around 15–25 seconds for a 70 kg rider. Noticeable, but not the whole story — the Allez Sprint's stiffness puts more of your wattage at the rear wheel.

Both frames clear 32 mm officially. The stock builds ship with 26 mm tires on both, which nearly every reviewer flags as the build's weak link.

For either bike, plan to fit 28–30 mm tubeless rubber on day one. On the Allez Sprint, that swap is closer to mandatory — it's the difference between 'jackhammer' and 'composed' on rough roads.

No. The current Allez Sprint generation is sold only with mechanical Shimano groupsets — Claris, Tiagra, or 105 R7100 12-speed at the top — across all six current builds.

If you want Di2 or AXS, you're either looking at the Tarmac SL8 (cheapest electronic build is the SL8 Comp at $4,699 with SRAM Rival AXS) or buying the Allez Sprint frameset and building it yourself.

Three reasons: aluminum frames are dramatically cheaper to manufacture than monocoque carbon; the Allez Sprint's component spec tops out at mechanical 105 instead of electronic Dura-Ace or Red AXS; and the Tarmac SL8's price covers Specialized's flagship R&D for sponsored WorldTour teams.

The Allez Sprint frameset alone retails around $1,700 — a fraction of what an S-Works SL8 frameset costs. You're paying for material, components, and a marketing tier all at once on the Tarmac.

Honest answer: the Allez Sprint is the more rational choice for crit racing specifically. The handling DNA is nearly identical to the Tarmac, the bottom-bracket stiffness is on par with carbon flagships (testers report lifting the rear wheel during sprints), and you can crash it without insurance-claim anxiety.

The Tarmac SL8 will let you turn faster lap times by virtue of the weight and aero, but most weekend crits aren't decided by a kilo of bike weight — they're decided by who has the legs left in lap 20.

Both use threaded BSA bottom brackets — a deliberate choice by Specialized that home mechanics and shop wrenches both prefer. No press-fit creak, easy to service.

The Allez Sprint's cabling is integrated through the headset but uses standard round stems and bars, so swapping cockpit components is straightforward. The Tarmac SL8 Pro and S-Works builds use a Roval one-piece integrated cockpit — adjusting bar width or stem length means buying a new $400+ unit. The SL8 Expert and Comp builds keep a 2-piece alloy cockpit, which is friendlier to fit changes.

Both frames carry Specialized's lifetime frame warranty to the original owner against manufacturing defects. Specialized also offers crash-replacement pricing — typically 30–50% off a new frame for riders who damage their bike in a crash.
