'97 GT Zaskar, Cannondale fork, older Paul hubs, Rhynolite rims. Magic gear.

Only new parts not from my bin ended up being headset, seatpost collar, bottom bracket, crank spindle, and tires.

I had more blue stuff but it was just too much, it took away from the frame/fork that look so good together. Doesn't need more distracting anno, just a touch here and there.

It's a blast to ride!
Thanks! It's real zippy and "quick" handling. Much shorter wheelbase and steeper HTA than my modern full-squish 29er.

I think I may need gloves with more padding!
There was much wailing and gnashing of teeth in the final hours. I had a crank with a 30mm spindle (Hope). I had a "30mm" bottom bracket from Box components. HOWEVER it turns out that several companies which ostensibly use a "30mm" crank spindle actually have a 30mm on the drive side, and a 28mm bearing ID on the non-drive side. Oof.

Of course my crank has a straight 30 spindle, but Box Components is one of those that use a 28mm NDS. After some fussing and thinking, I realize that what they actually do is use a small pressed-in sleeve on the NDS to bring the bearing down from 30 to 28mm ID. Well, what is pressed in can be pressed out! But I don't have an appropriate drift, BUT I do have a typical headset cup remover thing, which I slid into place and applied the 3lb sledge to and finally popped it out. Huzzah! What an annoying late-night thing to encounter, I'm lucky my workshop is on the other end of the house from sleeping family members, I made quite a racket.
