My two cents:
A few months ago I was in a similar situation to you. I had decided on either the P2C or QR Lucero, but really liked the Ora. Unfortunately, I could not find dealers who sold the Ora for anywhere less than $3500, far higher than the $2699 MSRP for the Ultegra build. One day I was in my local tri shop (an Orbea dealer) and they had a blue and white Ora for $2799. I eventually ended up purchasing this bike. Here are the pros and cons as far as I see them.
The classic: which fits you better? For me the Ora fit great. But I’m also a 6’0" male, not a 5’5" female.
Which LBS’s sell which bikes? Don’t forget that you are also buying a dealer. From school, I have to drive 4 hours to get to the nearest Cervelo dealer and 90 minutes to get to the nearest Orbea dealer. From home it’s 2 hours or 45 minutes. I’ve also been buying running shoes from the Orbea dealer for years and have a great relationship with the shop’s owner and all the employees. I would have much rather dealt with these guys than go to a shop I had no relationship with or mail-order.
Can you get the Ora at MSRP? A lot of shops sell the Ora for much more than Orbea recommends. If your shop is one of these, it is likely not as cost-effective as the P2C. Like I said, I got the Ultegra build for $2800, many shops sell this build for $3500. I would not have paid that price. $2500 for the P2C is a great price.
The Ora is the exact same design as the old Ordu, with a lower quality carbon fiber. This is the same design Craig Alexander rode to his second place finish and Kate Major to her third at Kona. I’m sure you are also well aware of Chrissie Wellington’s victory on the P2C and Rutger Beke has been known to ride it as well. IMO, neither design is a slouch and both can go very fast with the right rider and the correct fit.
“We are very picky with our sponsors and would rather race for dollars than just take anything that comes along…our amazing relationship with Orbea continues. Orbea have what we truly believe to be the best bikes we’ve ever ridden and the best bike company we have ever dealt with.” - Greg Bennet on his and Laura’s sponsorship.
One downside to the Ora is this: Orbea just updated the Ordu to a different design. This to me, is an admission that the old design could go faster. However, the same thing could be said about the P3C and and the P2C.
The P2C is a great bike, but I don’t think the Ora is getting its fair respects paid in this thread. Take everything with a grain of salt and remember, none of us actually know you or what would be best for you.
