Wider Tires on Specialized Sirrus
I am wanting a bike for fitness riding, mostly on road, but want a more rugged and upright position like that offered with a mountain bike. I like the idea of bigger tires to absorb the bumps, curbs, potholes, etc. I was looking at mountain bikes,GF Tassajara in particular; However, most of the people here agree that shocks are a negative for mostly road and light trail riding. I don't care about the difference in speed.
I am wondering if a bike like the sirrus, with bigger tires might be the better choice. How wide of a tire will the Sirrus accommodate? Has anyone gone this route and have any comments?
