Cervelo P2C - 58 cm Frame TT bike -> Road bike conversion

Hello all,

I have seen similar posts on this forum for Tri Bike → Road Bike conversions, but not for the model that I just bought. I was wondering if I could get feedback on some of the ideas I have for this Tri bike and potential conversion to Road Bike. First, here are the specs:

  • Cervelo P2C (2008) 58 cm frame (I am 6’1")
  • Dura Ace Components, it is a 2x10 speed
  • The rear derailleur is a **Shimano Dura Ace RD-7800 **(10 speed)
  • FD is a 2-by
  • Carbon seat post
  • Vision (Full Speed Ahead) Tri-Bar / Aerobar + Stem
  • Condition: Excellent condition, it has been ridden literally 11 times since 2008. 9 times by the first owner (cool story, this guy apparently flew air force for Obama) and 3 times by my housemate. So its basically brand new and has almost no wear, the tuning is pristine.

It would be nice to get feedback on:

  • Would it be a good idea to convert this to a road bike with a dropper handlebar + Shimano shifters?
  • What would the most economical shimano shifters be that would be compatible with the dura ace components? I was thinking about purchasing the Shimano Dura Ace 7800 ST-7801 2x10 STI Shifters
  • What would the most economical dropper handlebar to get?
  • What would be the best positioning for the seat post and dropper handlebar if I converted it to a road bike?
  • Any other ideas for parts + geometry?
  • Or should I just wait until the spring and sell it for a profit and invest in a road bike?

The only promising factor I see in the geometry for a road bike conversion, is that the seat post insert actually does tilt backwards somewhat, where as some tri bikes ive seen are perfectly horizontal for a more hunched over tri-bike positioning.

Welcoming and and all thoughts on this potential conversion (or sale), thanks

“Would it be a good idea to convert this to a road bike with a dropper handlebar + Shimano shifters?”

Nope.

Why not? I race crits and short flat road races with a P2C 51cm frame turned to a cheap aero road bike. It ist not comfortable but fast. I would not use it for an epic mountainous ride.

Search for desertdude’s posts on this type of thing.

While the front end is road bike-ish, with 61mm of trail it’ll be slower to react than a regular road bike.

If this is to just ride around it’ll be fine, if you were planning to race road or crit I’d get a road bike.

You can use any 10 speed 105, Ultegra or Dura-Ace shifters
You can get bars from $40 to several hundred dollars. Personally I like the aluminum Bontrager bars.
Your position will dictate which seatpost position you should use. The bike may or may not fit correctly, it depends on the size of your body.

I’ll play devil’s advocate here…

Why not? Depending on what you plan on using it for, and bearing in mind its limitations, it’s a high quality bike that would make a decent road bike, as long as you weren’t unrealistic about what it’s capable of.

Is it going to compete on the bleeding edge in a crit with “better” bikes, designed for that kind of riding? Probably not.

Would it be a great “all around” bike that you could do group rides on, casual (or even not so casual) rides, or even triathlons with the addition of clip on aerobars? Sure, it would be great for that.

I’ve owned Cervelo Dual and Soloist bikes with drop bars and clip on aerobars that I used for just about everything. The P2C has a bit more aggressive geometry, but I imagine it would perform much the same.

What’s the worst thing that could happen? Go for it.
