Those were on the bike already.
The bike was at whistler at Drop machine in 2004 when it debuted as the PDC 8two5 bike.
that's the only reason WHY those stickers are on there.
The bike used to be one of the momentum cycle DH bikes too.
I do believe drop machine was very similar to crankworx in whistler, at the time in 2005, it was called drop machine. that's why the bike has dropmachine stickers on it, cause the momentum cucle guys rode THIS bike in whistler for dropmachine 2005.
Dropmachine is an Ontario forum. Mostly Toronto-based (I know like 75% of the regular users personally), and not that well-known. But leave the stickers on! Jeff would approve.
