I posted this over in the BMC Forum in the "RoadMachine" thread, but I thought the wheel and tire crowd might appreciate seeing these as well.
I have been shopping for a wheel and tire combo for gravel/dirt road/mixed tarmac use on my BMC RoadMachine RM-01.
I wanted the widest tire I could fit between the rear chainstays. Also wanted tubeless, at least as an option, and preferably durable enough to withstand gravel without cutting sidewalls.
I picked up a set of Schwalbe G-One Speed 700x30mm Tubeless tires and mounted them on a shiny new set of HED Belgium Plus rims (thanks November Dave!).
Here is what I ended up with.
They seem to be a good fit - they are comfortably within the chain stays, and there is plenty of room at the fork crown and seat tube as well. I don't expect them to be long wearing, but hopefully durable enough to ride gravel without sidewall cuts.
They mounted up fairly easily - the first one didn't want to seat with my generic floor pump, and after fiddling with a couple of CO2 cartridges, I finally got it to snap into place. The second one was a little friendlier (experience I guess). With a little agressive pumping I managed to get it to seat with the floor pump. In these pictures, both are seated and inflated to a little over max pressure (80lbs). I'm going to let them sit over night before I pull the valve cores and put some sealant in them.
It will probably be a couple of months before the snow melts and I can get these out to the mountains for a proper gravel ride - once I do, I'll report back how they fare.
