I bought these as replacements for the stock wheels on my Trek Madone 5 series. My Strava pr's are almost all improving and I have even earned a KOM on a segment that has been my nemesis for over a year. I am 66 years of age so those are not easy to come by. It is taking me some time getting used to high speed on the down hill though.
these wheels are awesome, light and with minimal rolling resistance. Great for climbing and stable for the descent. Comfortable ride, while very stiff seem to provide a very smooth experience.
Only concern is in wet weather. Prepare to apply breaks way in advance of metal or aluminum rims, which is my only other experience. The carbon fiber does not provide the gripping ability when wet until they have been dried off a bit by the break pads. Open to suggestions on how to best deal with improved breaking.
