Waiting for my dog to be groomed, in a town I'm not in much, and dropped in to a big bike shop there (Road 'N Rock). Saw an off road bike with a single sprocket in the front. It looked smaller than my 34 on the back and had a cluster on the back with low gear big as a 40+ ... Googled when I got home and amazed to see there are off-road bikes that are 1050 and the 10 is the ring in the front!
