I've taken to turning down the bottom portion (where the TT and seatstays join) of my seat tube sleeves on the lathe. This is mostly because it's a PITA to get the mill scale off the tubing, and the lathe can do it for me while I do something else. It probably also saves 2.4 grams or something. Whoopdee doo.
This will be a road/cross/tour bike, with disc brakes and some light rack capability, as well as clearance for pretty big (35) tires and fenders. Sort of a Swiss Army Knife setup. I'm a HUGE fan of the Paragon low-mount disc dropouts for this kind of bike - they keep the brake caliper out of the way of your rack really well. Plus they are just cool.
In other news, I rode a 1:27.3 Kilo today. That's .2 seconds faster than my old record. Must be the new fork. Humorously, I wasn't looking where i was going when starting my sprint on the apron and almost hit Nowork's bike. I think I can hit 1:25 just by improving my godawful starts...1:20, though will take some actual power improvements. It would be interesting to ride on an actual 250m (or longer) track (maybe even one that isn't plywood) to see if I was faster. I have a really hard time holding the black line in the turns (and you have to do 16 turns on our mighty 126m track).
