Testing1, 2, 5 (No THREE sir THREE!)

I built up Mark II last Thursday with parts from my cyclocross bike. The process went rather smoothly, by and large. The headset went in without complaint, and all of the pieces fit together in a very bike-like manner. Things that I had been worried about, such as the cantilever brake bosses and the front deriailleur mount were absolutely rock solid. However, in a feat of miscalculation, I made the seatmast too tall for the intended customer, and had to chop it down and remake the seatclamp. This proved to be a rather annoying task, although it's given me a bit of practice making clamps. My second clamp however, turned out to be somewhat underdesigned, and cracked during installation. Lame. Super Lame. Better here than in Wisconsin though. So, I rethought the whole area, and redesigned the seat clamp with a more standard external diameter so that I could use an off the shelf binder clamp for it. Good idea, wish I'd had it sooner! After redoing that over the past weekend, I sanded it down and actually got to head out on some rides with the bike. Overall impressions are good, but I don't want to divulge too much until the owner gets possession of the bike and makes his own judgement. I'll post some pics in a bit.

  1. I just heard about you from my boyfriend and had to utilize my google skills. What a great (and interesting) concept.

  2. It's 1, 2, 5 (three sir!), but you're close :)

    What epoxy are you using for the wetting, layup, and holding the bamboo together? Are you putting any insulation between the carbon fiber and aluminum to prevent galvanic corrosion?

  3. Damn,
    I guess I need to re-watch some Monty Python. Wet with fiberglass and all the goodies. I believe I have done my homework. Time will tell.
