GrNY is an informal club to gauge the interest in gravel riding in the New York metro area. Since we don't have a lot of true gravel roads around here, compromises will be necessary much of the time (e.g. paved trails, quiet country roads), but the basic idea is to get away from cars and do gravel when possible.
A gravel bike or cyclocross bike (or possibly a mountain bike) is more or less required to participate since many of the routes will not be skinny tire friendly. For many rides the minimum tire width will be ~32mm.
