Amazing variety of takes on pedals for winter riding!

I commute every winter day on Nashbar Big Mashers.

Pedal cage is 4 inches wide and 3- 1/2 inches front to back with center supports. 530 grams. $15. These beasts have 26 sharp teeth on each side of the platform. They nicely dig into the Vibram of my Sketcher Sports Trail shoes.

Upside: they are the ultimate stable platform. They can also help save your life- as happened to me when a car jumped the curb last winter and tried to hit me in Boston's Fenway. I instinctively did an endo and was catapulted off a Marin San Anselmo down a ravine. Damaged the San Anselmo but the Big Mashers may have punctured the assassin's tires ;-)

Downside: if you do a lot of portage, the sharp points of the Big Mashers will tatoo your legs. I solved this problem by fitting No.1 (driver) golf club covers over the Big Mashers on my favorite bike, Jamis Exile. Tradeoff- temporarily lost the sharp teeth but don't have to always carry a tube of Bacitracin ;-)
