This is the Cervelo P5, built up TriRig style.

When we last looked at the Cervelo P5, we were detailing the ins and outs of the frameset. And at that time, we promised to show you the full build of the bike when it was done. Sadly, this isn't a ride review - the P5 shown here is a 58cm, and much too large for my 5'9" self to ride. So for the purposes of this article, you're looking at a display bike. And what a beautiful display it is. Every part of this bike was chosen for a specific reason, to make a fininshed product that is very light (just 15.7 pounds complete), undeniably aerodynamic, and as user-friendly as any bike on the market. It's meant to be the braniest bike on the road, without requiring a genius-level mechanic to maintain it. So let's take a look at what's on this beast.

Build Details

The frontal profile is nice and clean, thanks to a centerpull Omega brake and clean cable routing via the Sigma stem. Using these parts on the P5 keeps the cables completely out of view of the wind, but still easily accessible for adjustment, maintenance, or packing for travel.

I've written about the P5 several times, and always said I'd prefer to build up the bike with the UCI-legal Three fork. Fortunately, the frame we received from Dash Cycles to build up was exactly that. So we got to work making this into a bit of a dream machine. Part of the theme of this build was to stay light weight whenever possible. After all, this bike was going to showcase the Dash seatpost/saddle combo, as well as their 770g Gretchen disc wheel. So we based the build on SRAM Red, which has claim to being the lightest mechanical TT group right now. The crank got swapped out for a Lightning SL with Fibre-Lyte chainrings, lopping more than 100g off of the already very light Red crank (the Lightning setup is just 534g, complete with the bottom bracket and chainrings)!

I took the liberty to chock the build full of TriRig's own Omega brakes (front and rear), Gamma carbon extensions, plus prototype Mercury pedals, and a pre-production Sigma stem. Base bar duties went to the Profile Design Aeria, and although I probably would have put an Alpha bar on, there aren't any working samples of that beauty yet. Plus, it's kindof neat to have an Aeria on there, because with that bar, the entire bike becomes UCI-legal. I highly doubt there's much on the market that can even come close to this build in terms of weight, aerodynamics, or adjustability, but the whole thing is totally UCI legal, mechanically simple, and would make an incredible rig for long or short course.

There's really nothing more to say that can't be said better with pictures. So enjoy the gallery below!

  • The Cervelo P5, out for a neighborhood photo shoot.
  • The Cervelo P5 has a lot of really good angles to shoot from.
  • The P5 has a very deep aero chord behind the head tube, but doesn't resort to an external steerer to accomplish it.
  • It doesn't get much better than this - this P5 has all the nice toys.
  • The frontal profile of this very smartly-appointed Cervelo P5.
  • Here's the front brake on the P5. The P5 fork is slightly wider than its Cervelo-born predecessors on the P3 and P4, which Cervelo says actually works better with a rider's spinning legs.
  • As clean as it looks, this cockpit is fully cabled, but nothing sticks out into the wind, thanks to the Sigma and Omega working together so nicely.
  • With the Sigma stem hiding the cables, this P5 is as clean as they come. Absolutely nothing sticks out in the wind.
  • The Sigma mates beautifully with the Aeria, keeping the frontal profile to a minimum.
  • The Profile Design Aeria base bar was completed with our own Gamma Carbon extensions.
  • This shot gives you an idea of how the Sigma's cable routing works. Its simple and easy to install, and the cover is removeable for travel or adjustments.
  • The P5, just chilling out.
  • And there's the Omega rear brake, hiding behind the crankset. It mounts up, no problem. I ran full housing to the brake rather than split it at the top tube.
  • The Omega hangs out beneath the BB, presenting a nice smooth shape for the air to flow over. And yes, those are TriRig Mercury pedals.
  • R2C shifters up front, of course.
  • I put Profile Design's choice ABS Carbon brake levers up front. These are really fantastic levers, and weigh almost nothing.
  • Between the Dash Gretchen disc, Lightning SL crank, and Fibre-Lyte chainrings ... there's so much nude carbon here I might cry. Tears of joy, of course.
  • Dash's new integrated seatpost/saddle combinations are as stunning as they are functional. This P5 gets a TT.9 saddle with TriRig orange colors.
  • Three little set screws control tilt and setback, while providing an inexplicably secure platform. The 'brick' that connects the saddle to the seatpost can be made in a variety of profiles to provide different tilt and setback characteristics, if you have peculiar fit needs.
  • By eliminating the traditional rail structure, Dash has made their seatpost combination even more aerodynamic, not to mention light weight. This entire thing weighs about 240g, less than many saddles alone.
  • A KMC X10SL Gold chain finishes off this build in style, and keeps the weight down.
  • The Cervelo P5. What's not to like?
  • Another side shot of the beautiful P5.
  • A foot of powder is great for skiing, but can be a bit of a buzzkill for the cyclist. Still, there's something alluring about this bike just lounging in the snow.
