Steve Warrenwrote a review of Mercury Wheels S5 Wheelset - Tubeless on February 8, 2020
Familiarity: I've put it through the wringer
With over 4k miles on them. For me much better than my old Jet 6 wheels. I have them on my Tarmac and they ride great. They preform nicely on climbs and descents plus handle crosswinds good. Strong performing all around wheelset. Also they look great with the subtle grey decals. Well done Mercury.
