Erikwrote a review of Mercury Wheels M1 Wheelset - Clincher on October 10, 2018
Familiarity: I've put it through the wringer
These have treated me well. I have other wheels that I race on but these spend more time on the bike than anything else. Lightweight, somewhat responsive and durable.
Have not needed a true but after two seasons the shop recommended they be re-tensioned, nothing out of the ordinary just a little TLC.
The wheels roll extremely well for not being an aero rim.
