News bot Posted September 22, 2016 Posted September 22, 2016 Free from the constraints of rim brakes, the S3 Disc has been engineered to be stiffer and more aerodynamic than its rim-brake counterpart, while continuing to make the most of the lightweight design rooted in the Project California research facility.Click here to view the article

IceCreamMan Posted September 22, 2016 Posted September 22, 2016 (edited) "Free from the constraints of rim brakes" That's great marketing speak. I have a 2016 S3 and I always think to myself I wish I was not restrained by these rim brakes. Edited September 23, 2016 by IceCreamMan BDF, muagie, The GT Man and 1 other 4
Underachiever Posted September 22, 2016 Posted September 22, 2016 Good looking bikes, but too much marketing speak. Which means the product is not that much better than current.
'Dale Posted September 22, 2016 Posted September 22, 2016 Unless you live in Euroland and roll lots of wet roads 7 months of the year and spend hours in Alpine like mountains.... It's all marketing Exciting though ???? pista 1
Audible Anarchy Posted September 23, 2016 Posted September 23, 2016 Is there a difference in geometry between the traditional / rim brake one and the one with discs?
Matt Posted September 23, 2016 Posted September 23, 2016 Is there a difference in geometry between the traditional / rim brake one and the one with discs?No different to the S3 geometry wise - from another spec sheet for the bike: "The S3 Disc features identical geometry to the S3, with classic road handling and fit."

shaper Posted September 23, 2016 Posted September 23, 2016 Maybe marketing but is also technology driven. Biggest issue with carbon wheels is the braking surface and wheels can get only so light without serious issues in this area. Moving to disks takes everything away from the rims, keeps heat away from carbon, so potential for lighter wheels and differing carbon technology on the rims Mongoose! 1

I have a 2016 S3 and I always think to myself I wish I was not restrained by these rim brakes.I have the S5 with rim brakes on carbon deep sections. The humidity just has to go up slightly and those rim brakes become panic handles with very little relationship to pressure on the lever and stopping power. Coming down Spook Hill in Somerset West last night and I couldn't stop at the stop street! I can't see how discs are a bad thing. IceCreamMan 1
Mongoose! Posted September 23, 2016 Posted September 23, 2016 (edited) Manufactures of disc brake, road bikes, should play with the idea of covering the disc with a light weight non shatter ventilated carbon / plastic shell for safety purposes. just think of the marketing possibilities with such future... - eliminate the danger of cutting in accidents - more aero - more protected from dirt / dust Edited September 23, 2016 by Mongoose!
IceCreamMan Posted September 23, 2016 Posted September 23, 2016 I have the S5 with rim brakes on carbon deep sections.

Or down Not saying disks are bad but I certainly have never felt the need for them on any of my cervelos. My S3 sans disks stops just fine. Disks if anything may make it stop much quicker an that could be dangerous, Not sure how adding disks makes the bike stiffer unless there are other changes. The S5 to my knowledge is still constrained ...
Matt Posted September 23, 2016 Posted September 23, 2016 .... Not sure how adding disks makes the bike stiffer unless there are other changes. Another snippet from the spec sheets below. There are some changes which improve stiffness, notably the thru-axle front and rear. STIFFNESSAs with our other disc platforms, 12mm thru-axle technology boostsstiffness in both the back-end and in the fork, leading to better handlingin corners and an 8 per cent increase in headtube stiffness. We’ve alsoboosted bottom-bracket stiffness by 9 per cent to improve overallhandling and power transfer to the pedals. IceCreamMan 1
