The 25 mm tires when inflated to 6.5 bars rear and 5.5 bars front actually measure 28.5 mm. Because of this I can run these low pressures which make for a sublime ride. Frankly I have ben riding for 38 years and never have experienced this on any other road bike. Mind you that I am 6 feet tall and I weigh 190 lbs. I live in Florida where the winds are fierce and I have yet to notice any type of bobble with these wheels in a crosswind. How Enve accomplished that is just amazing. Finally these wheels just look so good on my all black Colnago C-60. Expensive yes but worth every penny. With the wonderful people at Bike Tires you even get amazing pricing on these wheels.
Purchased as a replacement for some aging Mavic R-Sys wheels. The SES 3.4 wheels weigh about 50 g more but the aerodynamic benefits are massive. The old wheels performed poorly in cross winds. Not so with these wheels. Ride quality is excellent and an improvement over the R-Sys wheels.
At a local road circuit race I had higher max speeds compared to the same race on the old wheels. Acceleration seems about the same.
Braking is okay. I don't think it is as good as the alloy wheels but the modulation, in general, is good. The patterned brake area on the rim creates a distinctive sound while braking. Not sure if that will fade as the rimbrake pad wears.
Setting up as tubeless was a challenge and much harder than the other tubeless tires I have set-up (cross bike). Not sure if that is the wheeltire combo or just the reality of tubeless road tires. I'm running Schwalbe Pro One tires.
The rims are wider than older rims so if you are running older brakes (like SRAM Red 10 speed) you will likely need to upgrade the brakes.
