Yeah, the hose goes through an 8mm tube inside the top-tube. I'm really impressed with the quality of the frame, its amazing. Even better than I was expecting really. The frame set me back £385 and I think the bike so far has only worked out as about £750 for the full build! The frame rides insanely nicely, its really weird, there appears to be no downside to it, Its suprisingly really nice for pure trialsy stuff, yet spins, bunnyhops and manuals insanely. Its made of T45 steel (same as curtis) The Geo on it is: 1050 wheelbase with those forks. (yeah, long for a 24" but it works well) 380 rear end (adjustable between 370 and 390) 25 BB rise 73 head angle Oh and as I mentioned above theres a gindplate/guard under the left chainstay that goes right around the back of the BB and down the first few inch's of the right chainstay. Will get some pics of it properly when I can get the camera back of my mum. The 6 week weight was because he was busy for 2 weeks then needed 4 weeks to build and paint the frame, not bad if you ask me, and well worth the weight. I'll get some better pics tonight probable when I get home from college.
