We got to ride the Cervélo S3 Disc Ultegra Di2 over three days on plenty of varied terrain, and our 58cm test bike weighed in at 8.1kg, which included two bottle cages and pedals in place. The bike came with Enve 3.4 disc brake wheels (Enve carbon rims on Formula disc hubs), a Shimano Ultegra Di2 groupset and the AB04 aero bar.

Cervélo S3 Disc Ultegra Di2 ride impression
From first swinging a leg over the S3 Disc it's apparent that this is something special. After recently testing (and being similarly impressed) by the R3 Disc, we had high hopes for the aero-optimised disc bike, and for the most part we were impressed.
The S3 Disc feels at once light, rapid and sharp, and it accelerates with impressive ease. The frame and fork feel rock solid in terms of stiffness and encourage you to dig that bit deeper into your reserves to live up to the bike's promise.

On the flat it's impressively rapid, with every pedal stroke rewarded with an addictive need for speed. A small but important factor is the smooth, silent running of the bike. We had no creaks or tweaks even over some pretty rough tarmac — and a section of gravel thanks to an overenthusiastic bit of Garmin routing. The bike was nothing other than silent.
Yes it’s a little less comfortable than the R-Series bike and we were surprised to see 23mm tyres fitted — even if they do come up broader than that on the wide Enve 3.4 rims. Ideally for rough UK roads we’d like to see 25s fitted and there’s room to spare for bigger rubber on the disc frame.
Light and responsive handling
