Those monster tires are called Schwalbe Big Apples and the guys at Schlick Cycles are using the biggest of the big, 28 x 2.35 rollers on the Smitty. Don’t worry though, through some very smart engineering these tires have low rolling resistance while giving you the advantage of pot-hole sucking action a good city tire needs. They also have great, reflective sidewalls for visibility while riding at night.

I’ve put several hundred miles on the current set of Big Apples and, knock wood, no flats yet even though I ride some pretty torn up streets. I love ‘em!
