DC and SE Racing have collaborated for a fourth time, this time to release an updated version of the Quadangle and PK Ripper Fixed Gear. The Quadangle, SE Racing's classic frame, has been revamped into a 26-inch cruiser. This is the first time that a large size frame has been featured on this bike. The new model is being featured in a bright fluorescent yellow that will be hard to miss on the streets. The updated PK Ripper Fixed Gear is a blend of an old school BMX and the modern fixed gear. Details from the classic PK Ripper BMX that have been incorporated in this new release include floval tubing, a landing gear fork and a loop tail rear end. The bike really pops with a bright fluorescent orange colorway.

DC and SE Racing first joined together in 2007 for their exclusive limited edition project 30 Years of Radness. The project honored 30-plus years of BMX history, and DC and SE Racing celebrated with a re-release of the PK Ripper bike in its original aesthetic for an exclusive limited edition quantity. Both bikes are available starting today, April 1, 2010 at select retailers. Truly collector's items, these bikes are extremely limited as only 300 of each were produced.
