What frame size would you put a 5'11" rider on (31" sleeve length, 32" inseam)?

Specialized makes the Allez Comp in a 54, 55, & 56 cm, and I'm trying to help a friend pick the right size frame for general training and the odd triathalon.

For the tris (only a couple races a year), he is simply going to mount an aero clip-on to his road bars & move the saddle forward.

If anyone has any personal experience with Specializeds in this size range, or knows of rules of thumb about sizing a bike for use with an aero clip-on, I'd appreciate it.

PS: my pal is a swimmer and cycling newby who
1) doesn't want a dedicated tri bike (= death ticket in NYC)
2) doesn't need an ultra-stretched-out riding position for training
3) has a great deal lined up on this particular make and model (Allez Comp)

Based on your three measurements, I'm roughly the same size as your friend. I ride a 56CM 2001 Allez Comp and find it a good fit.

All that said there's too many more variables to a call this a definitive answer. Your friend (with you in tow) should go to the shop and ride the bike(s). You should observe the position for elbow and knee bend and the shop should get out their plumb bobs for a KOPS testing, eyes to hub, and other helpful rules of thumb.

I'd be suprised that a 54 was a good fit, but both the 55 & 56 could work, test ride them and see.

Good Luck

yes, he said that the 54 probably wouldn't fit. 55 or 56 sounds about right depending on inseam length.

Make sure that your aero bars fit the oversized handlebars of the new specialized bikes. I had to sell my Profile aero bars cause they won't fit the larger handlebar.
