Right on Steve, you got it 100%!

Be sure, then install the Aduro.

One other quick thing, Damon - here:
http://www.cervelo.com/...012/P5/prices-specs/
It appears to show the Six frameset not including the Magura levers. I'm working on the assumption that's simply an error on the web page and it will come with them, but could you confirm this and ask someone to change the website if it is an error?

There are a lot of people modifying their Di2 to put satelite shifters, sprinter shifters and home made buttons (Cat-eye buttons) on their set ups. I know people that have moved away from the expensive shifters and are running Campy Record carbon levers (non ergo) and Sram carbon (non shifters versions) with modified buttons which is a fraction of the cost and work just as well.

There are a lot of options available to use the Magura hydraulic levers and still be able to shift at the basebar.

EDIT: I have a friend that is running Di2 and will not have it hacked to run sequencial shifting. Nothing like having a single button on each shifter (one for up and one for down) and letting the hacked Di2 do the work in getting you to the next perfect gear.

That appears to be an error since a brake is sold individually, but not as calipers only. So you can actually get a front brake only, but not only the calipers by themselves.

You could tweak future runs of the brake levers to include a recessed spot for home grown shift buttons to fit into, and be sure there is room for clean home grown wiring.

sort of like how shimano brifters have that little 'button' on the rubber of the hood for who knows what.

Fair enough! For what it is worth, I agree with you on the lack of integrated storage. I'm unwilling to do a 1/2IM or IM without a flat kit and multi-tool...I invest too much time and energy to just "hope" I don't have a problem and I don't want to wait around for neutral support. I don't need a ton of space, but it would be nice to be able to put that stuff somewhere that has been optimized by the frame builder rather than using an aftermarket product that might inadvertently detract from a design nuance.

Cool. I hope that means that we'll all be seeing some detailed data soon (i.e. a "whitepaper" or something) :-)

thanks damon.

so it is only the cables that hinder the use of the aduro on the p4?

I saw the x-ray photo of the cockpit of the p5 and noticed that the hole on the frame (under the stem) for the cables to enter is big and like a rectangle.

what if I simply enlarge my p4 frame hole same as the p5?

1. will I void my warranty?

2. is there a structural issue with enlarging the 3 cable holes to make it one big one like the p5?

on a different question :

3. will the p5 UCI illegal fork fit my 2011 p4?

thanks,

andrew

Really? No offense.....but, nice try. The shift buttons on the brake levers is a distinct advantage of the Di2 setup. I pass people coming out of every single corner in every race due to those little buttons. In fact, it is probably the strongest argument FOR Di2 on a tribike. Your bike is fantastic. The braking system is a huge feature.

If I were your PR team, I'd feed you something like: "We ultimately had to make a choice between the distinct advantages of a hydraulic brake setup and the convenience of the Di2 brake levers. In the end, we were able to engineer the fastest, lightest frame on the market, one that isn't confined by the limitations of traditional cable routing."

Please don't ruin a great feat of engineering and design by making up stuff like this!!!

Hey Weaver
stay in the aerobars in the turns ;)
(many of us do!)

I know! I see all you guys in your aero bars in those tight turns. Of course you are on lap one and I'm already on the run..... But I see your point.

Is the rear brake also the hydraulic Magura RT6? Based on the few pictures I have seen, the rear brake is not hydraulic which makes no sense to me. Who needs the stopping power of a hydraulic brake on the front? The rear brake is where you would need it.

I couldn't agree with you more.

both are hydraulic, but I'm curious about your reasoning for why you would need more braking power in the rear, when something like 90% of your weight transfers to the front under braking.

I use both brakes but with my P4 and the poor braking power of the rear, I really noticed a huge difference in performance. I feather the rear brake and noticed I wear those pads much more than the front.

Hitting your front brake only is a recipe for flying over the handlebars.. It's my cyclocross background -- I only use the back.

While it is certainly true that you can't flip your bike over with the rear brake only (since you lose any braking grip as the rear wheel lifts)

you also can't stop as fast as possible using only the rear, not even nearly as fast as possible.

So you might learn to use the front too in case of emergency, or to get through a turnaround as quick as possible =)

So many options to put shifter at the brake for Di2 but everyone wants the world. You can have the hydraulics and Di2 shifting but you have to pay for someone to do it for you. Not cookie cutter but it can be done and for cheaper than you think.

Damon,

I wish I could rephrase my "shift at the brakes" question because it suggests that I think you have been unresponsive. You have done an amazing job getting questions answered on this site and I'm sure it is VERY much appreciated.

While I wait for my awesome new bike I will continue to research the most elegant solutions out there for getting shift buttons to work well with the new Magura levers. My guess is you just created a market for the solution so hopefully someone will respond. I'm guessing that by the time all these frames arrive in a couple months there will be a fair amount of effort put into this.

Hi Steve,

Yes, it comes with the levers - they're required to operate the hydraulic brakes. ;-)
From here it looks like they've already fixed the site. Thanks for the heads up.

Cheers,

Hi Andrew,

0. Yep, the cables are the only hindrance - the Aduro clamps to a standard 1 1/8" (28.6mm) steerer tube.
1. Yes, "joining" the 3 cable holes is not recomended and will void your P4's warranty.
2. see above
3. No, sorry, both P5 forks' significantly larger crown would interfere with the P4's dropped down tube.

Cheers,

Good point, well taken. I was recently reading a thread debating this and found many posters saying that they didn't use them that often, but it's clear now some Di2 users feel strongly otherwise.

We certainly would have liked to have been be able to offer Di2 buttons near the brake levers, no doubt. We "almost" had a batch modified to sell but in the end ran out of time debating warranty responsibility. Of course any individual can solder as they wish. Others have made good suggestions along that line.

I like your suggestion - mind if I use your words? :-)

Thanks Weaver,

Damon

Hello Damon,

Does the introduction of the P5 affect the P2, P3, and P4 offerings in 2012?
