Cervelo has long been a leader on Aero technology and frame design, and you can see that in the S3. From the clean integrated cockpit, to the aero tubing, and seatpost this bike is designed to go fast. Super stiff around the BB, so the power transfer was great. That stiffness paired with the Geo gives great quick, responsive handling. Even though this frame is not necessarily designed for climbing, its no slouch. It felt right at home on a 6k climbing day for me. The stiffness does provide for a harsh ride at times. If your roads are particularly rough, I would say perhaps to look in a different direction. All in all, this is a phenomenal race bike. You won't be dissapointed. I'm 6 3 and rode the 58, and 61. 58 felt best out of the two!

- I've used it several times
Let's face it, aero is in when it comes to features that are desired on new bikes nowadays. I made up my mind a while ago that a few watts saved here or there based exclusively on aerodynamics doesn't mean a whole lot to me, especially if it comes at a cost of comfort in the saddle. That is, until I spent some time on the S3.. Upon picking up the bike, it felt a little weighty, probably on the side of 8.6 (ish) Kg. that's a rough estimate, not weighed on a scale. Hopping on the bike was a whole other story. Saddle & geo felt extremely comfortable - carbon layup felt stiff in the pedal strokes, with not a major difference from other carbon bikes when going over harsh(er) gravel. No complaints about cockpit or touchpoints on the build - aero bars were fine when my hands were on the tops during climbs. nothing fussy with the internal seatpost. Internal wiring makes the bike look exceptionally clean, and not having floppy wires aids to its' aero claims. Ride quality was pretty fantastic overall. I found myself grinning ear-to-ear on flat sections, as I was riding 2 - 3 mph faster without notice. Descents felt extremely fast & confident through corners, disc brakes only accentuating that confidence in late braking. Build kit was stellar, Ultegra Di2 NEVER failed in all shifting - even when testing some front shifts under load. I didn't necessarily feel like I could "dance" up climbs as well, but every pedal stroke provided excellent power transfer - making it a candidate for hilly or even mountainous terrain/climbs. I'm 6'3" weigh 170 (ish) - rode a 61cm build. Felt very comfortable and could probably take some spacers out if I wanted. If I wanted to go full race mode, I would size down to 58cm.

Feels Aero but is heavier than expected
- I've put it through the wringer
I love the geometry. It seems to be a good middle-ground for a race geometry. Not super aggressive but not too upright ether. For a Ultegera level bike at 7k, it should have had nicer wheels. I am not happy with the Novatec they felt sluggish. I swapped them out for a pair for Black inc 55s and I am happier with them. My S3 is size 54 and with only Vector pedals and cages weighs in at 19.3lbs. Which I think should come in at under 18lbs for a bike at this level. One thing to be aware of with a lot of these bike with proprietary stems is that in order to change the stem or headset bearings, you will have to disconnect everything from the cockpit including the brake lines. So if I had the chance to do this again, would I buy an S3? Unforutanly the answer is probably not.

Wow, something must have happened between 2018 and 2019 models. I have a 51cm 2018 S3 SRAM Red eTap (11 spd) hydro disc brakes that came with ENVE SES 5.6s. With pedals and bottle cages it weighs 17lbs 12oz (weighed at bike shop using their calibrated scale).

If you are in the market for a stiff aero race steed you owe it to yourself to checkout Cervelo's S3 disc. The fully internal wiring setup of the Shimano Di2 R8070 drivetrain gives this bike a super clean cockpit free of wires and housing. Impressive stopping power gives you confidence heading into the turns as well as helping you avoid that careless driver (which I discovered firsthand on my first ride). Your can really put some power through this bike. It accelerates on command and handles better than I would have expected. Descending the steep canyons here in Utah is a breeze and you can hold your line in cross winds without too much trouble. Sizing for Cervelo is based on Stack and Reach which makes it easy to get you on the right frame size. The 56 fit me perfectly at 6' and a 32" inseam.
