I just finished this up and thought I'd share a few shots of it before heading out for a weekend of autocrossing........lot's of Vettes and 911's to do battle with. Wish me luck.

Your fillets are amazing as always. :)

That brings back a memory. The first Kirk I ever saw in person was glc's fixed-gear, and I drooled over it. He rode PBP in 2007 on it, and I had the pleasure of sharing some miles with him that year.

Dave -

It is my dream to ride PBP fixed - what an accomplishment. i could not think of a better bike to do it on than something crafted in your shop. well done, looks like it will be a beauty.

I will not ask you to share who the owner is, but if you could encourage them to post over here on the PACELINE as to their experiences riding PBP fixed on your wonderful machine, that would be great!

...Why the horizontal dropouts?

...Why the horizontal dropouts?

So the chain tension can be adjusted - and they are forward facing slots so that the wheel can go in and out with a fender on (a royal PITA with track drops).

You sir, are a wizard!
That is fantastic. Did you choose horizontal dropouts to make fender integration easier than with track dropouts?

Besides aesthetics, what are the advantages of bi-lam construction?

None really - it's just another way to hook the pipes together and it looks cool with the blend of lug and fillet.

When I was with Serotta we made HUNDREDS of bi-lam bikes. We called them 'half lugs'. We did it because we were using tube sizes or shapes that lugs weren't offered in. If you look at any of the early Colorados you'll see them.

But today they are done purely for the look.

Looks to be another lovely bike. But atm im more envious of the racing. I really want to do battle against vettes and 911īs in an orange lotus too! Sounds like a lot of fun!

Beautiful frame, but forgive my ignorance but what does bi-lam mean is it a combination of using lugs and fillet brazing? Nice lotus too is it an Else'?

I had to look that up too. Aren't they like fake lugs? The two tubes don't meet inside a cast lug. Learn something everyday here I love it. At first I thought extra brass was added to give that fillet look.

David Kirk
06-22-2012, 11:18 PM
Bi-laminate is not so much a faux process as it is a mix of things. At Serotta we called then 'half lugs' and what they are really is 1/2 lug and 1/2 fillet.

The way I've always done them is the same way I did in this case and that is by taking a lug and cutting it in 1/2 and slipping it over the tube.

In the end it just gives the top or down tubes extra support and looks cool once painted. It ends up looking like the entire head tube is one piece and organic and that top and down tubes slip into it.

There is no 'vertically compliant - laterally stiff' deal to them or anything like that. They just have a cool look that this particular customer craved.......and since he's a good repeat customer I felt good about doing something different for him.

I look forward to seeing how it wants it painted.

This is the second bike I have ordered from Dave.

I to was at PBP in 2007. That is where I saw my first Kirks. One may have been the same one mentioned in an earlier post. I remember seeing them in Paris on some bridge with street performers. One was black and geared and the other was brown and fixed. I believe both guys were from New York and I talked with them breifly. On the last day of the ride I ran into the guy on the fixed again and rode with him for a few miles, I think. Two years later at the 2009 NAHBS I was looking for a bike for PBP2011 after talking with all the builders and remembering the kirk from '07 I ordered my first custom and first Kirk. I couldn't be more pleased. The bike is beautiful and the ride is better than I could have imagined. I rode it on a 1000k in TN in 2010, PBP in 2011(Dave has some pictures of it on his blog) and just finished the Shenandoah 1200 on it a few weeks ago. After going back to Paris in 2011 I was thinking of ordering another custom, for my birthday, when I got back. While visiting the Singer shop in Paris I noticed the beautiful bikes and the bi-lam construction for the first time. After I got back stateside I was looking for another custom. With the Singers in my head I asked Dave if he could do work like that. He said he could and at that point it was a no brainer. Why not have the Guy who built my best riding bike build me another. I thought a lot about this bike and Dave thought of all the other things I forgot to consider. I couldn't be more pleased with the way this bike looks. Now to figure out what color(s) to put on this beauty. I have a few ideas but I am taking suggestions. Any Suggestions? It's will be built up with all silver components and fenders.
Thanks,
BamBam

bambam,

your bike rocks, and the fact that you're going to ride pbp on it fixed is also totally rockin'. as i mentioned earlier, one of my all time goals to do the ride fixed. you and this bike are an inspiration. keep up the good work, and make sure to show it off when you decide on a paint scheme.

p.s.

i've always been a fan of kirks painted with the "gulf" scheme.

Thanks for the complement but thats all Dave Kirk's hard work.

I like the "Gulf" scheme as well but I think it would look better on a bike with black components. Whats the rest of that bike look like?

It could be up for consideration in a less busy configuration.

I feel the paint job should be less complicated so that it brings out the work better. Sometimes I feel the Landsharks and Pegs look better with a more understated scheme.

I may ask JB to surprize me?

I figure I have a week or two to decide.

I'll post pics when I get it painted and/or built up.

Waiting anxiously to see the finished product! Thanks to the builder and owner for sharing...let's those of us not yet able to pick up a Kirk live vicariously a bit. Quite frankly, starting a thread here should be a requirement for any forum member buying a custom bike!

Was showing my wife this bike last night and she said "you should put down your deposit." I'm gonna put that one in my back pocket as I'm still basking in the glow of the new/used Colnago I just picked up.

I've got a box marked "mid-life crisis" in my basement with a NOS 7700 group in it that is just waiting for a Kirk to come along. Might have to be a bi-lam.

Awesome.

Dave, I know your work is not lacking for compliments, but when somebody rides your bike for 1200+ kms, and then feels so good about the experience to order another . . . that's quite an endorsement, imo!

have you decided on a paint scheme yet?

bambam

I have a few ideas and have passed them on but I am letting JB have the final say. He has a ton more experience in this field and knows what works best. Just waiting for him to get around to it. No hurry. Its like christmas eve when your a kid, but it last a little more than a night.

David Kirk

So - some time has passed and the frameset is painted and as of today on its way to its new home. I thought I'd share JB's paint work and how it all came together with the metal work. Pretty damn pretty even if I say so myself. I like it.

To many fun miles!

Dave

that is nice work Dave. did the rack get painted to, or was that stainless steel?

i really, really love this bike. hope to have one very similar someday. bambam - maybe we can ride some fixed miles together sometime. maybe even in paris. cheers.

I am excited I will be getting this bike soon.:banana: Dave and JB do some Great work.
All the parts will be silver, even the rack. It will be a Nitto Rivendell Mark rack or the similar M-18.

I always enjoy riding with new people and in new places. So yes, AS, I hope to ride with you someday as well. Maybe even on PBP2015 or maybe I'll come up to NJ to ride some brevets next year.

Now, I just need to start building those wheels. At least I have all those parts. The summer here was to good to stop riding long enough and build them.

The excellent paintwork really highlights some amazing details - I think my fave is the semi-wraparound seatstay caps.
