Internal hydro line ports done and now it's time to braze the front triangle together.

Are we looking at a TT or DT? Do you use a grommet or something to help prevent water ingress?

It seems like internally-routed frames must end up with a lot of gunk in them over time - I guess unless there's a tube brazed into there - but the carbon and aluminum mainstream ones certainly don't have that...

This is a DT and you are looking at the port just above the BB shell.

There is a full length, thin wall, brass tube brazed in place so debris can't get into the down tube. The hood on the end is stainless so that if the paint were ever damaged on the port that it will not result in any corrosion.

I cringe whenever I see bikes with ports that just open into the tube. This is just bad design anyway you cut it.

I'm just finishing up the first JK Special built for 12 mm Thru Axle and disc brakes. Now your JK Special can fit up to 35 mm tires while having the classic Euro Stage Race ride.

That was my first thought as well (of course, after a series of mental stumblings not finding words about how spectacular this looked!)

Hi Dave -

Are we looking at a 44mm head tube? I have a lugged 44mm gravel bike and it looks immaculate. Having said that, the builder swore that the amount of time it took to create it was far too labor intensive. Is that why they're so rare? Just curious. Thx.

Thank you for the question.

Nope - this is not a 44 mm head tube. No one makes lugs to fit that standard so when I build with that size I only do fillets.

Glad to see you go with an asymmetric chainstay, as the drive side drop would have been unnecessary long and unattractive IMO. I would prefer to have the flat mount with two simple posts instead of integrated but milling and brazing two individual posts would probably be more complex to craft. Nonetheless, it would be cool to see a through axle version of your 3D dropout. Thanks.

A little Jen Green head badge action. Jen is the real deal and I'm proud to feature her hand work on the front of my bikes.

True story. And if the dang thing wasn't so fun to ride I'd have more pictures to post of it all built up! Every time I throw a leg over it I get all wrapped up in the joy of spinning the pedals and forget to pause for a photo shoot..
