Got Blocks!? The 26" Blocks Flyer is the bike to have if you want to raise it up with the crew and catch some blocks. This year's frame has been improved with an internal headset and mid bottom bracket. The new 26" x 2.4" Bozack tires ride great and provide super traction for those swerves. If you want to be about that SE Bikes life, you need to be riding the Blocks Flyer.
