Space Cadet said:The new 29's use a different chip than the 7222 (I'm not sure the exact date this changed, sometime late last year I believe). IIRC it's something like YD1022 (not sure of the number, I can check Monday when I get to the shop). It is an altogether different chip, and currently there is little info on the net about it. Only source I have found for them is Cobra.
