The Donnelly BOS cyclocross tire is an incredible all-conditions tubular tire. It's a supple, grippy, tire named after the airport code of Milan, Italy the location of the cyclocross world cup, and as a nod to Clement's Italian roots.
"The BOS Is an outstanding and grippy intermediate cyclocross tyre. It has a pretty wide window of effectiveness and is confidence inducing for the less experienced and skillful rider" - Rob Allen www.cycletechreview.com
The tire features a new version of the classic Grifo profile, which was first created by Clement decades ago. The new version of the tread includes slits in the central chevrons for flexibility and soccer cleat-nspired side knobs.
The BOS works phenomenally well on inconsistent ground and in a huge array of environments. It dominates in sand, grass, loose dirt, hard dirt, snow, moderate mud, snow, and (of course) pavement. If you could only have one set of cyclocross wheels, this is the tire you want.

"If I had to choose one tire tread to run all season long, the Donnelly BOS is my pick for the most versatile cyclocross tread currently available." Daniel Slusser artscyclery.com
