Mountain Flyer Magazine.

July 15th, 2014

One of my favorite magazines of any genre is Mountain Flyer Magazine and I’m honored to be the featured framebuilder in the latest issue – #37. I’m told it’s on the newsstand now in most markets and if you subscribe you should already have it on your nightstand.

The main man at Mountain Flyer is Brian Riepe and he does a kick ass job and working with him on the profile was very smooth and fun. I was also excited to work with Bozeman writer Walt Burns and local photography legend Bob Allen. Both Walt and Bob have a slightly left-of-center view on things and this jives very well with my outlook and take on things and it made the whole process easy and rewarding.

So take a trip to the bookstore and pick up a copy of Mountain Flyer and check it out. I’ll be surprised if you don’t want to subscribe to it for the photos alone but the writing is the real deal.

Thanks so much for looking –


MRB – Montana Road Bike.

July 11th, 2014

About 10 years ago I started making bikes for riders that I called MRB’s……….Montana Road Bikes. Here in Montana when the roads leave town many of them turn to dirt yet that is where some of the best riding is. So bikes were built to deal with dirt roads and wider tires and the geometry and handling were optimized toward riding on mixed surfaces. Over the years I’ve built a lot of this style of bike. It’s interesting to see that the rest of the country has embraced this time of riding and that it’s been given the name ‘gravel grinder’. I suppose everything needs a name or it doesn’t actually exist and that’s fine……I’m just glad that so many are discovering the joy of riding on real backroads and not turning around when the pavement ends.

This frame has been this week’s work………it’s an MRB version of the JK Special with Terraplane seat stays, hydro disc brakes and Di2. I look forward to getting the fork for this one wrapped up and off to paint so that I can get it back and build it up. Should be cool.

Have a great weekend.


Dirty Kanza 200.

July 1st, 2014

Just the other day friend of the business and customer Steve sent me a photo of him competing in this years Dirty Kanza 200 and I like it so much I asked if I could use the photo. Steve said it was cool to post it and then gave me some of the results and stats.

The Dirty Kanza 200 is a 200 mile Gravel Grinder race that saw over 800 riders start this year with only 469 finishers. Steve, riding his fillet brazed Kirk dirt road/cross bike equipped with disc brakes finished in 181st place in a time of 14.5 hours. Steve told me he was very happy to be in before the sun set………and with good reason. Steve is a hardman to be sure.

Nice work Steve.


Kirk Mountain bikes?

May 27th, 2014

It’s hard to say why it’s been so long since I made myself a new mountain bike. There was a time when I raced at a high level for Ritchey East (long time ago but feels like yesterday) and I traveled on and raced the NORBA pro circuit in the north east……….I designed and built countless offroad bikes during my Serotta days and of course Carl Strong and I tag teamed about 1000 Ibis mountain bikes from here in Bozeman. The riding around Bozeman is high alpine epic and I rode my old bike and enjoyed it but never wanted to take time away from my queue to build myself something new and more advanced. Like the cobbler’s kids I guess…….

But the time came this past winter to get ready for the snow in the high mountains to melt by making myself the first new mountain bike in more than 15 years.

I chose to go with a fillet brazed hardtail built for 29′s and of course wet disc brakes. I got it back from JB awhile back (signal green!) and finally took the time to indulge and hang the kit on it. I want to tweak a few things still (like getting a more burly stem and post – had these in stock) but I have the fit and set up dialed now and it’s a really wonderful ride even if i do say so myself. The frame is plenty stiff with XL sized tubes and the Rockshox fork with its through axle and handlebar lock out and it gives the whole package a very precise and accurate feeling on single track and wonderful high speed tracking on double track……….the big wheels really do roll wonderfully over the rough stuff and maintain momentum very well on climbs. Great stuff.

In the past I’ve not been known for making mountain bikes and people tend to think of me as a road guy………fair enough………that said I’d love to build some more of these and welcome orders. All bikes will be fillet brazed and of course be made to measure with the main option being a rigid or suspension fork. If you are interested please be in touch and we can go over the pricing and options and get you in the queue. Please consider the order book open for MTB sales………………..

Thanks as always for looking and have a great ride today.


Available now.

April 30th, 2014

Thanks so much for the interest – the frame has been sold.

Fortunately this doesn’t happen very often but it means I have a bike ready to purchase with no waiting – this bike was ordered and about ½ way through build the customer notified me that he had no choice but to step back from the order. Since the design and half the build was done I chose to finish it and offer it for sale with the new owner getting to make the decision on how they wanted it painted.

The main tubes are Reynolds 725, the chain and seat stays are Kirk by Reynolds, and the fork blades are Reynolds 853. The lugs are simple long points, the crown is Cinelli and the rear drops are Kirk Triple F’s. The seat stays are of course the curved Terraplane design.

The frameset is designed to work with a modern standard road brake and there is plenty of room to fit a 28mm tire. The geometry is straight up euro stage race and meant for long fast rides on a variety of paved and smoothish dirt roads.

If this is of interest to you take a look at the BikeCad image to see the basic fit numbers. The design as shown considers a -6° stem with 20 mm of spacers under it. If these numbers look close to yours and you’d like more info or to talk price please contact me directly at and we can go over all the details.

As always thanks for looking.


Fixed Gear, Disc brake, JKS.

April 25th, 2014

This one is a bit toward the end of the bell curve. It’s a JKS built with Rocker dropouts so it can be run as a fixed gear while using disc brakes. The fork is designed and built to be used with discs too and there is room from and rear for fenders.

The owner likes to do some ‘easy’ 400K rides on the weekend and to make it challenging he does it on a fixed gear. Very cool.

Thanks PUDU for having me build this for you and to JB for the stunning paint. Very cool.


That’s a Wrap.

March 19th, 2014

Well – the last of the 10th Anniversary bikes went into a box today and off to its new home and I must say that even thought it’s been a shit load of work I will miss them. I just love the color and the look and it won’t be the same around here without some hanging around.

The design and build of these bikes has been going on for many months now and it’s been a real push of work followed by a lot of waiting and then lather, rinse, repeat…….and I got to the point where I wondered if they would ever be done frankly. I’m much more used to a bike taking a week in process at the most and when I’m doing a batch like this that takes months to build and work out all the details on then it seems to take forever.

I’ve got way too many photos to share them all and we will be culling them down to a select group and making a slide show and a video or two in time but for the moment here are a few dozen that I liked while skimming through the pile.

I would be remiss if I didn’t take the time to thank everyone involved that made this whole thing possible. There is no way the bike would have even been built let alone come out just right without the help of the following –

• Reynolds of England for making me the tubes I need to give the bikes the feeling I really want them to have.
• Dazza of Llewellyn Cycles in Australia for designing the best lugs money can buy.
• Mark Norstad of Paragon Machine for making the special machined parts in the very limited quantities needed for these bikes. Most shops won’t answer the phone for an order of 1000 parts let alone 10 but they stepped up and made it happen.
• Gary Prange of SSSink who took my sketches and photos of mockups and turned them into the artwork that perfectly matched the image in my mind’s eye.
• Jenn Green who took my idea of a thin and simple headbadge and made it come to life in stainless steel.
• Joe Bell, the best painter on the planet. Joe worked with my ideas and added his own until we had a real collaboration. Words can’t express how much I like working with this man. He truly defines the words partner and gentleman.
• My wife Karin for supporting the idea of the business from its inception in 2003 to these very bikes in 2013. She has been there every step of the way and without her I’d not be able to do what I love to do for a living.
• Lastly a huge thanks to all those that signed up for one of these bikes to help celebrate the decade. Without you I’d just be standing at my bench with nothing to do and that would feel pretty silly. And a hearty thank you to everyone that has supported me and this business for all these years. I wouldn’t know what to do with myself everyday without your help. Thank you very much.

That should do it for now……….the last one is out the door and I’m going for a ride now.

Thanks as always for looking and stay tuned for a bunch more photos in the coming weeks.


10th Anniversary Bikes Shipped.

March 14th, 2014

As of today all but one of the 10th bikes have shipped with the exception of one still waiting on its kit. Here’s a collection of signatures. Once i’m sure the bikes are in the owners hands and that I won’t be spoiling any surprises I’ll post of bunch of photos of them.

Thanks for looking and have a great weekend.


Steve’s cross bike.

February 3rd, 2014

I recently got these photos from customer and friend of the Frameworks Steve and they show some cross racing from last season. Steve’s bike has disc brakes and is fillet brazed and painted a deep, wet and inky black.

Thanks for the photos Steve.


2014 – Looking Ahead.

January 14th, 2014

The year 2013 was more a year of looking back at the previous ten years than it was looking forward to the next ten – while 2014 promises to be much different being solely focused on the future both near and far.

There are a number of things in the works that will be phased in this coming year and while there are a few I’m ready to talk about, the others I’ll keep under my hat for now.

The biggest product news is the introduction of two new models – the final details and model names are still being worked out but I can say that I will be offering a new road model and for the first time a full-on offroad bike.

First the road bike – I’ve always wanted to build a full stainless road frameset and offer it sans paint but have always held back because I didn’t feel the tubes available would give the ride I wanted – and – I guess I didn’t really care how good it looked if it didn’t ride how I feel a road bike should. But things have changed and the good folks at Reynolds have listened to my long time pleas and now offer a full stainless tubeset, including the super important chainstays and fork blades, that I feel will make the bike ride as good as it looks. So with the tubes in the bag it’s a matter of having my proprietary front and rear dropouts cut from stainless as well as getting lugs, crowns, bridges and braze-ons on the way. I should be ready to build the first sample very soon. As for the finish – I can say it won’t have any paint but beyond that I won’t say for now. Pricing has not been finalized yet but will be once the first sample is complete. If you really can’t wait and want to get in the queue sooner rather than later be sure to let me know.

The other new offering will be a first for Kirk Frameworks as a company but far from the first for me as a builder. I’ve had many folks ask about mountain bikes over the years but I’ve always been so busy that I never made the time to make it happen. But my past is calling and I feel the need to make the time and follow the strong urge to build some mountain bikes again.

My mountain bike riding, racing and design go way back and the first custom bike I ever had built for me (a custom fillet brazed Fisher – 1987) was a mountain bike and the first bike I built for myself shortly after starting work at Serotta in 1989 was a mountain bike. I also raced on a nationally sponsored team (Team Ritchey) up until about the time I started working at Serotta in 1989. Being as tall as I am (6’4”), and having strong technical riding skills, meant that as a racer I’d have more success offroad than on and I did pretty well even if I do say so myself. Over the years I really learned what made a mountain bike ride and handle well and while I was at Serotta I was instrumental in designing their mountain bikes – the T-Max, Ti-Max, ATi, and the Ti Softail were all designs I had a large input on and I’m excited to use those skills again. Couple that with the fact that we have more than a little mountain biking here in Montana to test the bikes on and I’m pretty excited. As with the stainless road frameset the details aren’t all finalized yet but I can say the bikes will be available with 29”, 27.5” or 26” wheels depending on the size of the rider and the use of the bike and that they will all be fillet brazed. As soon as the details are finalized I will be announcing pricing – that said if you know you interested please don’t hesitate to get in touch and we’ll work it out.

I’ll be announcing the other company changes as they mature and am excited to out the stuff I have in the works………… please stay tuned.

As always – thanks for reading.
