I've been testing a 2015 Fuji Gran Fondo to see whether this style of endurance road bike is something I like.

My prior riding experience has been on CX / Adventure bikes with minimum 32mm tires and MTBs.

The Fuji has 25mm Vittoria tyres which felt super thin at first, and I was planning to replace these with 28mm road tyres such as the Conti GP4000S. I find the ride with 25mm tires a bit bumpy on poor surfaces.

Unfortunately, the Fuji is already really tight with a 25mm tire in the rear, so that option isn't open to me (a 28mm will probably fit in the front).

I do like the feel of the Gran Fondo though, and could well see myself getting an endurance road bike in the future - but - one that can take wider tires.

To my question: which commonly available endurance road bikes have the widest tire clearance?

I know the Trek Domane (with disk brakes) has 32mm tires as standard, and could go up to 35mm, which is unusually wide I believe.

What other common endurance bikes can fit a minimum of 30mm tires?

I realise the boundary between endurance bike and gravel bike can be a bit blurred these days, with bikes like the GT Grade considered in both categories. I'm thinking more on the "road-side" of the spectrum with sub 8.5kg carbon bikes, probably with disk brakes.

Thanks for any suggestions!

John.

Doing some research of my own, I found:

Trek Domane (disk): 35-38mm depending on reports
Focus Paralane: 35-36 (maybe up to 38mm)
GT Grade: 35mm
Cannondale Synapse: up to 32mm (anecdotally)
Specialized Roubaix: up to 32mm (anecdotally)

Any more that are comfortably in the > 30mm category?
