Mercury Wheels S5 Disc Wheelset - Tubeless

I’ve had these wheels for 6 months with over 1400 miles with no problems. . They are lightweight, extremely stable, and aerodynamic.. They cut through the air nicely, and crosswinds do not have much effect. Very smooth hubs. Highly recommend.

The S5's are a perfect depth for me. I am a lighter rider, so am highly susceptible to any sort of winds and ride mostly on or near the Monterey coast where it is always windy.

For the first ride, I threw them in my "go to" bike (Tarmac) and rode my regular Tuesday night 30 mile group ride. I immediately noticed a difference in cornering and out of the saddle sprints. They track nicely and didn't notice any lateral flex.
Second ride would be a century where at the end of the ride I didn't feel beat up and felt better than I usually do after a century. They handled nicely even with some severe cross winds.
My third ride will be over the labor day weekend where I will be riding 3 days in a row for 200 miles. The route has over 5K feet of climbing, so am anxious to see how they perform in the hills.

great wheels.
smooth bearings and I like the gun metal gray hubs.

I have my the Peter Sagan Gran Fondo coming up and wanted to roll a faster set of wheels. Was a snap to place my new DA cassette body on and shifts perfectly.
The wheels are light and feel like a nice pair of wheels. You can tell the quality is there.

You always hear about wheels making the biggest difference on your bike, but never thought I was good enough.
Raced in my third Tri ever and actually beat the guy I have been gunning for in the previous two races. He usually beats me in the overall time and bike leg.
Not this time! I beat him by over 2 minutes on the bike alone and by 3 minutes overall!!
I also broke my previous average speed by 1.6 mph.

I just upgraded my stock wheels on my Ridley to these full carbon wheels. I can’t believe these wheels are sub $1000. Great all around wheelset that actually light weight. Nice rolling hubs.
