700x30c for Cannondale BBU

Yesterday I found a couple of knobby tyres that may fit my BBU and would allow me to ride better off road with my stock set of rims. So after mounting them I can say that yes, the Schwalbe CX Pro H269 700×30 does fit the stock Sun rims and HeadShok of a Cannondale Bad Boy Ultra.

They leave just very little space but do not reach the HeadShok valve.

Silly me.

Thinking of MTB tyres and 29’ers I had completely forgotten the cyclocross category.

These Schwalbes should be a huge improvement when ridding off road. My old Conti slicks are very reliable, haven’t even got a flat in two years and handle well in rain. But when they start hitting the dirt… well let’s just say they were not meant for that.

If these 700×30 fit, there is a good chance that any of the nice 700×35 Maxxis cyclocross tyres will fit as the second number indicates a width increase, for which the Fattys have enough clearance as shown in the second picture. And a little fatter tyres will provide a better ride for the narrow rims I’ve got.

So now, do I keep these tyres or put back the Contis and return the Schwalbes in exchange for the Maxxis?

Yeah, I know, the computer sensor cable looks awful. Wireless Strada or V3 is next.

Space is tight but it’s not rubbing at all.
