About a week ago, I did a short test ride on a Specialized Turbo Vado SL followed by a Creo SL Carbon Comp. I preferred the riding position of the Creo and was strongly leaning in that direction to enable a fast ~40 mile round trip commute as described:
Avid cyclist looking to reduce 40 mile round trip commute
After doing more research on EBR and elsewhere, I really wanted to try a higher power motor. So I went back and took two back-to-back rides - one on a Trek Domane+ HP 7 (they didn't have the lower model) and then the Creo SL Comp Carbon.
I had mapped out an ~2.5 mile loop (including an ~55 ft / 5.5% grade) climb near the LBS and rode it twice on each bike. Unfortunately, I screwed up my Garmin's start/stop and missed a little of the first loop. I created a 1.82 mile segment on Garmin Connect to compare the four laps.
Domane: 4:05 (26.8 mph) and 4:11.6 (26.1 mph)
Creo SL: 4:41 (23.4 mph) and 4:55 (22.3 mph)
Both bikes were set to max assist and it should be noted that the Creo had just 3 bars of battery (out of 10, I think) showing when I started, dropped to 2 bars during the ride and was showing a single red bar when I got back to the LBS.
I realize that these results are not "scientific" as I wasn't measuring my own power input, but my seat-of-the-pants sense is that I was working quite a bit harder on the Creo to go slower. I knew within 0.5 mile that the Creo was the slower bike - and by quite a bit. How much of this impression had to do with the dying battery, I'm not sure.
A few other notes: I was definitely impressed by the Domane. The lockable and removable battery back is very nicely integrated into the down tube. Despite being ~10 lbs heavier (I think), the Domane didn't feel like it was that much heavier. I also liked the integrated headlight, taillight and Bosch controller.
I didn't pay huge attention to ride quality, but the Creo SL has the FutureShock front dampening while the Domane has some kind of flexible rear seat configuration for rear dampening. At ~25mph, both bikes could beat you up a bit over rough asphalt.
I'm looking for a fast commuter, and both bikes have provisions (eyelets) for fender and rack.
I will admit that I didn't want to, but I came away from the test ride very, very impressed with the Trek Domane+ HP 7.
