B-17 standard, gotten off ebay for $50. Decided to see what all the fuss is about for my IRO build. Damn this thing is heavy - I knew half a kilo is a hell of a lot for a seat, but it really hits you when you're holding the thing. It weighs more than my fork. But whatever, an extra 300 grams isn't going to kill me. I'm planning to chop it down - is wallbike the only place with pics of chopped up brooks? I'm looking for tips and ideas. I understand a utility knife is enough - I don't really have accesss to a grinder, though it looks like I'll need one for the bag tabs.

Wish me luck guys.
