agreed! where did you get the tires?

 Since the PB26 had arrived to Japan two days ago, I bought it. mmm, in other countries, I think that it has not arrived yet. pb26 is 2.1 but fatty than other brands. weight 650g

 TT is 540mm, F axle - BB is 640mm.

 oh-oh.. as for me, its TT is so short it's really a bmx-type mtb and it's good that it has enough dimension between tyre and pedal
