The 25mm tires are rubbing and they didn't when I had Zipp 303 on Cannondale 2017 EVO.

Seems like every time I put any pressure or even turn, tyres rub the frame. I'm only 140lbs (63 kg) and this is my 3rd Cannondale EVO but never have had any issues until adding ENVE wheels.

I added the Enve last year. They didn't rub during the Cache Gran Fondo only started after I got home (Colorado). They've never really rubbed, just started after Gran Fondo trip. I'm using the same Continental Gator Skin tyres as I had on the earlier on Zipp 303 wheels.

  • What rim width are the ENVE rims? what width were the previous rims? Did you have 25mm tyres before?

    Hi, welcome to bicycles! It might help if you include a picture of where it is rubbing. Is the rear or the front? It appears that ENVE wheelsets come standard with some models of the EVO, so maybe it's the tire size that's a problem?

  • Check your skewers for deformation. Check for frame for damage and cracks. While still, can you push the wheel rim sideways with hand pressure till it touches the frame?

    Slightly off topic, but if you can afford zipp/enve wheels, why on earth are you using gatorskins?

Many rear wheels with high-profile rims lack lateral stiffness. The beefy rim itself may be stiff, but there may be too few, too thin spokes, possibly at too small angles. As a result, when you ride out of saddle the rim and tire may be moving sideways enough to rub the frame or brake pads.

Here's a very good article if you're interested in this in detail: Debunking Wheel Stiffness

Also, you're not alone with this problem with Enve SES wheels: ENVE SES 4.5 with ENVE hub => brake rub
