I'm told that shops are able to swap, but I'm not sure how simple or easy it is.

I know that if I were a Cervelo dealer I'd make the EX-10 mono riser standard on the P5d for most riders, except for ones like me in which case I'd make a tilt wedge under the pads standard.

I had both the P5D and a PX for about a year, I had the P5X before these as well... the P5X was a great bike but the PX is a definite upgrade over the P5X. I rode various versions of Speed Concepts before this ever since it was released.

I needed to sell a bike though and chose to keep the PX over the P5D for a few reasons, it wasn't an easy choice and both bikes have aspects that I really liked but for me the PX was the better bike to keep.

Weight between the two is negligible, The P5D with Dura Ace Di2, Enve 7.8 wheels, Dash saddle/post combo, 2 rear cages, one one the frame and one BTA was 18.7 pounds on the road, that's with cages, pedals, Garmin mount etc. The PX in an identical configuration was 19.9 pounds but that's also with the built in flat kit and Ceramicspeed OSPW. The PX was weighed without the large storage box which I don't need, if you need that it will add a good bit of weight.

The P5D has slightly longer reach which really worked for me, I hated the stock bars and couldn't get comfortable on them at all but once I swapped those out to the P3X/PX front end it made a huge difference. I prefer the ride quality of the PX and how solid it feels. One of the main selling features of the PX is the base bar that can be split but I actually prefer the fit and feel of the P5D base bar.

I struggled with the decision on which bike to keep but when it came down to it I just like the versatility and uniqueness of the PX so I chose to keep that. Can't go wrong with either bike really, I raced the P5D in three Ironman races last year and never had an issue with storage or anything. Just personal preference for me and wanting to have something that's slightly different than anyone else plus wanting to ride the bike every time I look at it certainly helps with my motivation! The P5D looks just 'meh' to me but it a great bike to ride and has a more traditional look which it seems most people prefer.

Cervelo is the only beam bike that's faster than double dimonds, whoops diamond bikes.



And yet the P5x is exactly that. Loaded up or not. We proved that

I have a very short list of bikes that are faster than my heavily modified Scott Plasma 3 Premium and a ton of data to back up what I'm about to say. Cervelo makes the only non double diamond bike that is faster than my current plasma and the only one I'd switch to.

I don't know if it's a dampening effect really, like you say the 'beam' isn't your typical beam and isn't suppose to dampen your ride like the old beam bikes... what I do notice is an isolation feeling from the road, I guess without chainstays that makes sense. Probably also related to the massive tube shapes used in the PX. The roads where I live are horrible, a lot of rough pavement and chip seal but I barely notice it and the PX just feels super solid on the road.

It's almost as if 25 years of making a fast or the fastest bike has gone into Cervelo making the PX. Hmmm...

"That crowd" is increasing riding what *I* tell them to ride, not what the shops or pros tell them to ride.
