Hello All,
I have searched and read about the P5 on ST.
Late to the party but I am finally getting a new Cervélo P5 ..... albeit a 2014 frame ….. and would like to read any of your thoughts or additions and deletions as to what you might do for the bike setup ….. since many P5’s are out there in the wild ….
Changing from a trusty Cervélo P3C that I have used for several years.
Nytro will add eTap, Quark, Q rings and the rest pretty standard …..
I am not planning to mount any shifting blips on the bike ….. but rather to attach wireless shifting devices to my body and hand or hands.
Not having tested a P5 in the wind tunnel I am using reported information for location of bottles, tools, and Bento Box.
I will be testing a post mount Dash saddle downstream and if it works OK will not use the View-Speed Stash to hold tools under the seat as on my P3C since the Stash uses seat rails to fasten.

Excerpts:
1 “However, a standard round bottle mounted horizontally between the rider’s arms was a revelation! It filled in the turbulent area behind the rider’s hands and actually reduced the drag. So this set up was not only faster than the vertical bottle, but faster than no bottle at all!”
2 “The Cervélo P4 with its integrated P4 bottle is the only case where the water bottle does not add drag and slow you down seen below in Figure 6.
3 “One final nugget is that we found that a Bento Box behind the stem was a solution that had no drag penalty. However, this may depend on stem & spacer details and how many gels and bars you stuff into it.”
1 A horizontal bottle between the arms …. helps reduce drag …. Although I am wondering about how to accomplish this if my arms tip up 15 degrees or so ….. and does the combination still work or is it a choice ……. Of a horizontal bottle …… or of arms tipped up …….. but not both for best drag configuration?
2 While the P5 is not a P4 ….. I am thinking a tool box faired into the space above the bottom bracket similar to H & T Wurtele’s P5:
Modified Torhans Aero VR bottle …….
Follow
“H & T Wurtele
@TeamWurtele
@joshlongney @TorHansAero Yeah, basically just line it up with the frame and cut as needed. I left an overlap over seattube to it stays put”
3 And I will add a Bento Box since it adds no drag penalty and would be a very convenient place for some gear or food …. especially on training rides.
==================================
It looks like P5 travel packing can be a bit time consuming with a lot of dismantling.
This is from an ST post ……………..
“Here's a packing briefing, taken from the Cervélo web site I think. Are you using a hard-shell case? Fork on is...going to be tough to do. The hydraulic brake lines and cable routing make it tough to get around completely disassembling the entire front end:
Travelling with a P5
� Remove the front brake from the fork. The removal of the front brake cover is not necessary.
� Loosen the stem pinch bolts with a 4mm Allen wrench
� Remove the high mount or the top cover if using the low mount of the 3T Aduro Aerobar.
� Remove the top cap and drop the fork out of the frame.
� Remove headset parts and place aside.
� Remove the beard from the fairing mount.
� Remove the rear derailleur, leaving the e-wire connected.
� Lay the bike frame & fork into the case.
� Put protective padding between the frame and the aerobar to prevent damage during transportation.
� Wrap protective padding around exposed parts of the frame, rear derailleur, crankset, and fork to prevent transportation damage.
� Place any loose parts (headset, bolts, etc) in a small bag. It is advisable to secure the small parts bag so it doesn’t move around and cause potential damage.
� Cover the frame and components with foam or other sufficient padding.
� Remove the skewers from the wheels and attach them to the spokes.
� Cover the frame and components with foam or other sufficient padding.
� Tighten down the straps and put the cover on the case.”
Are there quick disconnect hydraulic fittings that might speed the tear down and build up?
My bike will only have hydraulics …. no cables ….. so that might speed up the process …..
What do you think?
