Dave, I appreciate your documenting this build sequence. It illustrates very clearly the extreme precision of your work. I look forward to seeing this frame in Austin! Thank you.

Thanks for the comment. The frame will be there along with bikes that are actually painted. Please be sure to stop by and introduce yourself.

Lots of varied stuff available in the classifieds here at Vsalon with better photos at my blog - Kirk Frameworks Custom Bicycles

Buy early and buy often at Crazy Dave prices. I need beer money for the show and I don't like cheap beer.

Dave, thanks a bunch for the fuel line trick. I had some laying around so I made myself an artificial thumb. It's great for getting in the corner of the bb/dt/st joint.

Very good.

I saw my first 3rd thumb tool at Serotta a very long time ago and had no idea what it was. At the time each guy was more or less responsible for setting themselves up with their own tooling and I was suffering trying to figure out a way to get into the nooks and crannies of fillets. Then a guy there named 'Barney' (he was called Barney because he looked just like Barney Rubble of the Flintstones) showed me his 3rd thumb tool and I made my own. There were lots of failed designs (wads of duct tape around the end were the worst) before I came up with the rubber hose idea. It seems just about ideal.

I'm glad it's working for you. Have fun.

It's 50°F outside today but I have a dislocated toe (!) and can't get into my cycling shoes - so I'm sharing photos.

This is my personal bike with a cobalt blue paint job compliments of JB. My photography skills may not show it well in the photos but the panels are matte instead of high gloss and look so cool outside.

This bike and the others are headed to Austin as of yesterday and I hope you'll stop by the booth and take a closer look and say hello.

Have a great weekend.

The gentle slope looks great - what post are you using there? Is this an OOS tubeset? Can't tell because the bike is so huge!

Hey,

Yes it is an XL tubeset and the seat post is a prototype of post being made for me and the maker of the fine lugs used on this bike. It's a first prototype and there is more work to do but it's very promising.

It's funny.......... to me my bikes never look big in person but always look huge when I see photos of them. I guess I'm kinda tall! I never feel tall but my bikes say otherwise.

Thanks for the question.

Is that a 30.4 or 30.6 post?
I guess with XL tube on a large bike the fork crown looks kinf of small.

[Dave Kirk]

The post is a 30.6 mm to work with a lightweight thin wall 1 1/4" seat tube and Dazza's lugs.

Thanks for asking.

Dazza, who is making this seatpost?

Dazza, who is making this seatpost?

We are keeping that under our hats until things are completely finalized - but I will say that it's made in the USA and is top shelf.

BEAUTIFUL! Is that orange bike also an XL tubeset? I seriously can't tell...

Speaking of seat tubes and posts, assuming the lengths are appropriate, would it be ok to use a TT as a ST with ~5-6cm worth of the butted portion at the seat lug? I wonder cause with a 0.8mm wall you could use say a 30.0 Thomson post, yes?

Hey Hansen,

Thanks for writing.

The orange bike uses normal OS tubes (1 1/8" top and 1 1/4" down tubes) but the Big Blue Bike (BBB) uses the XL stuff.

Yes it's perfectly acceptable to use a top tube as a seat tube assuming the butt lengths work out properly for both good solid clamping of the seat post and a long enough butt at the BB end. The seat tube in the BBB is 953 and is most often used as a downtube. It has long butts so both ends work out well and it's silly thin in the middle to keep the weight in check. It works very well.

One could use a heavier wall and end up with a more common post size but the tubes are more than strong enough even with the very thin walls so I'm opting to cut down the weight.

What do you think?

Humm. My current supplier for that diameter is WR Compositi. But Edge would be good ;)
