Specialized Road frame
Specialized Allez Size Chart
Allez is Specialized's alloy road frame and it runs 44 to 61 cm. Allez Sprint is a different frame with its own ladder that starts at 49, so a Sprint size does not carry to this one.

How neighboring sizes compare
If you're 178 cm and fall inside both the 54 and 56 ranges, compare reach and standover rather than assuming the larger size is more comfortable.

Sizing notes
Why height alone is not enough
Riders with the same height can need different sizes because inseam, torso length, flexibility, and preferred handling differ.
3 checks
Allez stack climbs 124 mm from 44 to 61 while reach grows 36 mm, so the front end rises more than three times as fast as the cockpit lengthens. That is a road fit built around bar height.
Specialized publishes 58 and 61 for the same 188–196 cm band. The two differ by 33 mm of stack, 6 mm of reach, and 31 mm of standover, so a rider at the top of the ladder has to choose on geometry rather than height.
The 56 to 58 step adds 20 mm of stack and 8 mm of reach, and 58 to 61 adds 33 mm and 6 mm. Both are large front-end jumps, so test the size before buying if you sit near either boundary.

Questions
Allez Sport size chart FAQ
Short answers for Specialized Allez Sport sizing.
What size Specialized Allez should I ride?
Start with the Specialized height band: 44 for 155–163 cm, 49 for 163–170 cm, 52 for 170–175 cm, 54 for 175–183 cm, 56 for 180–188 cm, and 58 or 61 for 188–196 cm. Then confirm stack and standover for the size you land on.
Is the Specialized Allez the same size as the Allez Sprint?
No. Allez runs 44 to 61 cm and the Sprint starts at 49, so the Sprint has no 44. The frames are also different: at 54 the Sprint carries 537 mm of stack and 387 mm of reach against the Allez's 569 mm and 370 mm.
What size Allez fits a 178 cm rider?
178 cm sits inside Specialized's 54 band of 175–183 cm. It carries 569 mm of stack, 370 mm of reach, and 781 mm of standover; 52 stops at 175 cm and 56 starts at 180 cm.
How do I choose between an Allez 58 and a 61?
Specialized publishes the same 188–196 cm height band for both, so height does not separate them. 61 adds 33 mm of stack, 6 mm of reach, and 31 mm of standover, so take 61 only when you need the higher front end and can still clear 852 mm of standover.
Does the Allez come in 44 cm?
Yes. Specialized publishes 44 for 155–163 cm with 519 mm of stack, 356 mm of reach, and 715 mm of standover. The Allez Sprint does not build it.
