Because of cold temperatures today I tried for my 85kg 105psi at the RW with 23mm GP 4000 SII measuring 27,5mm tire width on a wide HED Jet 6+ rim and will go back to no problems 100psi definitely ..

150-160 lbs

At that weight I would try 85 rear and 80 front on 25s

I weigh 150 lbs and set for 85 psi rear/front for 25/23 mm tires with latex inner tubes

I had a different experience with Veloflex. The 25c tires I ran on Pacenti rims were much wider than a 27c Open Pave I used afterwards. The Veloflex stretched out quite a bit over the first few days and gave a wonderfully supple ride that I really liked.

Unfortunately I cannot recommend the Veloflex at any price as I've run two sets And both times the rear tire has 'unpeeled' in several sections at the bead. I inspected the rim and found no abnormalities, and I've had no issues afterwards running Vittoria and Schwalbe tires.

I'll echo others' sentiments: way too much pressure.

That being said, there is nothing about the new S5 that should make it dramatically different from a vertical compliance standpoint than most other carbon road bikes. I hope you took the stock saddle off immediately, because that thing absolutely blows. It could be a major contributor to a "stiff" feeling ride..

new cervelo was so great.
i use it for 2 months.
So nice to have the bike

Now I'm kind of curious. I'll try sub-100 psi on the 25mm for the S5.

But--would you guys be admonishing me also if I said I was running 23mm at 110 psi? Because that's what I do on my Tarmac and Roubaix (bad weather bike) with no issues / complaints about compliance & comfort...

I generally run 100ish on 23mm (155lbs). For race situations where I have a 700x24 on rear I go 85 (this is TT/Tri). I would assume you are running different wheels on each of the different bikes...?

Yes--different wheels. S5 with 404s; Tarmac with 303s; Roubaix with Mavic trainers. That said--still maintain the latter two with 110 psi on 23mm Contis. Which I raced (bikes) on all last year. + did my tris with 808s on 23mm Contis at 110 psi as well (prior season did 120 psi). Drop 5 psi, potentially plus, if wet.

So sounds like I could go alot less (90-100) on 25mm and a bit less (100-110) on 23mm, but I'm not completely out of school on what I've been running on 23mm tires.

The quietest morning of the year. A good start with achievements from the last season to the next for all .. oSo >>

Edit: Upsi, we are here 9h before server time and even 18h to sunrise.

Riding the S5 for nearly one year now there is one thing that stands out of training peaks. There are some people out there who really know what engineering accomplishes, they create machines scoring like instruments that excite to „listen & sing a long“ .. oSo >>

Man, the same thing happened to me last week on my S5! Never had it happen before either.

Won't happen with eTap :)

Hey all

I have the current S5 with Di2 setup.
Is there a way to route the di2 cable through the rear brake grommet? I think I saw someone do that...it would be much cleaner than the di2 cable going in through the top tube.

thanks!

A buddy helped me out with an new one, that is a little bit thinner and feels more pliable. Have to ask for the brand. A good chance to check all the small stops, the frame guide still looks pretty well.

I thought Shimano was over with this cable bending issue ..

.. maybe I'll shift less now, one time in 111km instead of two ;-)

As far as I know for all Cervélos, if not all UCI legal road bikes, the Di2 cables should run from the top tube entry through the down tube to the fd & chain stay to the rd ..

As far as your rear derailleur cable snapping it's pretty common on the new polymer coated Shimano cables. I snapped one at 12 months and 10k miles on my S2. I plan to replace them every 5-7k miles to prevent it from happening again.

Yes, the RD cable snapped. Under the grip rubber the shift cable is observable and the FD looks fine so far ..
