We really upped the ante with the 29″ Big Ripper HD. This bad boy comes equipped with Tektro hydraulic disc brakes and a LOUD 9-pawl freewheel. The frame features an internally machined integrated head tube, Floval Tubing, looptail rear end, American bottom bracket, and classic PK Ripper style wishbone plate. Combine all of this with the super grippy SE Bozack tires and this very well may be the raddest Big Ripper yet.
