    1997 GT Edge Aero

    The GT is going dark for awhile, I will say its complete with the exception of cabling and bar wrap. I will update this thread at completion at some point in the future. I have been doing mega overtime for a while now and and a build on a new (old stock) carbon time trial bike has started...

    Fred Thomos was a very dedicated guy, anyone who can revive a long expired mark and survive the experience has my utmost respect. His line of A-D bikes were interesting, attractive and virtually unknown on the West Coast. But everything I have read indicates the bikes are solid. There's...

    Second thoughts... The aerobars will probably evolve into a dedicated time trial bike sometime in the near future as any installation of aerobars on a road bike involve cockpit/rider position changes that involve more parts swapping than I'm willing to do on a project this far along. There is a...

    My problem is shiny objects that send me down rabbit holes that "might" be a good idea. But you will never know if you don't make the trip. : Mike

    A day late but stuff done. Titanium rear derailleur pivot bolt installed and ordered 2ea. 7mm x 35mm seatpost adjustment bolts in titanium of course and that's about it for the golden hued magic metal. I actually had enough coffee to adjust the brakes front and rear and shorten the drops up a...

    At home I have a tiny Atlas lathe with a 4 inch chuck but at work things get better... A Cincinnati Model 13 Lathe, 40 inch carriage with a 9 inch swing. It has a decent 1990's Anilam DRO, probably a 1960's machine. The shop has 2, Series 2 Bridgeports one from 2010 and one from the early 1960's...

    Hi Frankenorange, I hope your having a great day Industrial tubing is always marked with what applicable specifications are met along with lot/batch number, country of manufacture, and who made the stuff, usually ink marked. I am a creature of the military-industrial complex so commercial...

    So what's happening with the GT... Getting sick slowed everything down, the good news is I'm feeling better and minor detail projects are progressing nicely like replacing the stem bolts with titanium equivalents. The titanium stem draw bolt was easy to find as a off the shelf item from Ti...

    I have created the world's only freehub single speed unicycle. Unfortunately I feel like crap today so we are not going to get around to even starting the cabling but it thumb shifts nice. The stickers are my homage to the 96 Olympic sponsors for the GT team and are era correct and if I learn to...

    Hi Bikeworkshop, It would be nice to have the aero seatpost but I'm working with what I have, but.. If a Tiemeyer geared time trial frame shows up in my size I think I would be all over it. Writing this stuff helps keep my head in the project as the back story is a good one, just digging it...
