130mm <--- 135mm?

The wheelset in the pic above was built for another frame I was intending to build up that had a 135mm spacing at the back.

The CAADX is supposedly spaced to 130mm.

But the rear wheel just drops in, no problems. The fit is a little tighter than the 130mm stock wheels; when closing the QR on the stock wheels you can see the dropouts clamp together. That's not so easy to see with the 135mm rear. But it's certainly not a fight to get it in and there's no 'pinging open' required at all

Should I reduce the 135mm rear to 130mm? Will the world end if I don't?

I've had a 135mm MTB hub in my 130mm CX frame for years. The actual spacing is probably around 132mm, so youre bending each drop-out 1.5mm. No worries.
