In 2017 Cervelo fully embraced disc brakes with disc versions of the S3 and R3. We’ve sourced event company Hot Chillee’s ride captain bikes which means RCE can offer amazing deals on these lightly used bikes - now’s a great time to buy as these won’t hang around until spring.

The S3 is Cervelo’s first aero disc equipped bike.  It looks a little more conventional than the S5, taking design cues from the R-series, but is only slightly less slippery and it comes in a little lighter. Whilst still a stiff, responsive, race bike it’s tuned for a little more comfort with thin seatstays and a bladed aero seatpost designed to have some flex at the top to further improve comfort.  

The conventional thinking is that disc bikes are less aero but with the disc version of the S3 Cervelo have improved aerodynamics on other parts of the bike so that the complete packages is more slippery than the previous rim brake version. We’ve already had enough damp weather in late summer to show that the predictable all weather performance of disc brakes isn’t just a benefit in the winter months. The bike comes with Cervelo’s proprietary aero bar which has the benefit of using a standard stem so adjusting bike fit is easier.

The R3 is engineered for low weight and uses Cervelo’s Squoval tubing that mixes square and oval profiles -the theory being that square shapes resist bending while round shapes resist torsion. Surprisingly the disc frame is lighter than the new rim brake version.

Both the R3 and S3 are thoroughly modern designs with Cervelo’s Rapid Axle Technology - a sprung loaded 12mm through axle - keeping both both front and rear super stiff (and putting to rest any fears of ejecting front wheels). The redesigned rear triangles allow for the use of wider tyres - up to 28mm on the R3.

On our bikes the gearing is mostly Ultegra but with an FSA chainset to allow short 405mm chainstays to keep the handling quick (normally disc brakes result in 415mm). If you want to switch to Di2 gearing in future the frames have all the requisite ports. The bikes also have upgraded wheelsets - Mavic Cosmic Carbon Pro - rather than the factory fit HED.

Compared to the R5 and S5 the geometry and ride characteristics are slightly less extreme and there’s a bit more comfort at the expense of out-and-out stiffness.  

We’ve got up to £2200 off the retail price if the lightly used bikes we have in stock.
