Both the All Road 650b and the Brevet 700c models are true low-trail designs designed to be used with a handlebar bag sized front load.  There is provision for easy routing of lighting, and both models (except in the smallest sizes) have a stud to mount our proprietary seatube mount battery tailight.   Both models have ample clearance for fenders (see our warnings about fender use) and also have a pump peg, 3 sets of waterbottle braze ons, seatstay chainholder peg, and a mount on the left seatay for an additional battery light.

All Road 650b

A great choice for added comfort or if you do some off-road riding.  650b extraordinarily comfortable yet amazingly fast.  Designed for a front load, lighting, and fenders.  Comes in two versions - regular light oversize or superlight skinny (except large sizes).  Clearance for 42mm tires with Berthoud or Honjo 50mm fenders.

TIG or Lug?

We love lugged frames, but all the love in the world doesn't enable them to actually ride better or faster.  So the reality is that a $1,435 Tig Boulder Bicycle frame will perform just as well on the road as one of our $6,000 Rene Herse frames.

 

 

Remember - the use of fenders carries safety risks!  Debris can cause a front wheel lockup which can result in a terrible accident!  Click Here to go to our fender page to learn more.

 

 

Why is Boulder Bicycle Special?

A Boulder Bicycle frame represents the latest step in a journey to build frames that perform without compromise.  The designs of our randonneur frames are obtained through careful study of classic Rene Herse geometries and those of other French makers.  Some of the "classic" designs work better than others, and we obviously select those from the best-performing historic examples.

Over the past 10 years the French randonneur bicycle saw a rebirth in the United States.  Mike Kone, lead designer at Boulder Bicycle, was one of the early proponents of French randonneur machines.  In fact, some of the most notable writers and modern proponents for this style of bicycle saw their first Rene Herse bicycles in Massachusetts when Mike Kone owned Bicycle Classics inc.

Classic geometries are juxtaposed with modern materials to create the current line of Boulder Bicycles.  Waterford Precision Cycles does the actual frame construction.  Waterford was somewhat reluctant to embrace the low trial and light tube specifications used on Boulder Bicycles, but they have come to appreciate the performance of these machines.  In addition, Waterford brings expertise to the Boulder Bicycle line which is unique to the industry.  Waterford has arguably built more custom and semi-custom high-end steel frames than perhaps any builder in the county.  Their understanding of materials combined with their access to proprietary materials is an invaluable asset.  They are unyielding in their quest for reliability.

There are many builders constructing randonneur style bicycles.  But our extensive experience yields advantages.  We know what geometries are most likely to perform well.  We know when we are pushing the envelope with extra light tubing.  And as students of bicycle history with many examples we've personally ridden, we know what is most likely to work well for a rider.

Many of our Boulder Bicycle customers think of their purchase as a stepping stone to a Rene Herse.  They are welcome to think that.  But in reality, there is no performance gain in going to a more costly frame.  If there was a better tube or a better geometry for performance, we would use it on the Boulder Bicycle.  But there isn't.  A Rene Herse frame (or a frame from some other wonderful builders such as Peter Weigle) may offer cleaner wiring integration or more elegant lug shaping or fancier racks.  But when it is you and the bicycle and the mountain, your Boulder Bicycle will deliver the same ride and performance as a frame costing many times more.  So please take advantage of our experience and eye for value, and let us supply you with the bicycle that will provide the ride of your dreams.     

       

 

Skinny Extra Light Tubing

As of September 2013, stock small and middle size Tig Frames are now available with skinny extra light tubing without an upcharge!  About 35%  of frames we currently build are with these tubes (1" .7/.4/.7 top tube and 1 1/8" .8/.5/.8 downtube).  These tubes are NOT for everyone, But we can discuss and help you choose if they are right for you.

 

 

The Wait Time

For both tig and lugged Boulder Bicycle frames wait times are getting longer - but compared to other builders the wait times are still very reasonable.  As of November 2013, the wait times for your new Boulder Bicycle from the time we finalize your order with Waterford is approximately 10-12 weeks for tig frames and 20 weeks for lug frames.  These wait times are our best estimates at this time.

 

Deposit

A deposit of $1,000 gets the process rolling.  You can make your deposit online or call the shop.

 

 

Sizing your bike and fit Mock-ups

It is vital that your new frame fits.  And we take lots of time with our customers to help them, and we have size info on these pages that will help guide you.  But we are not fitting experts nor can we fit you easily from a distance.  We are happy to provide mock ups of a stock geometry frame with your saddle height/reach/drop info (or provide custom drawings once you commit to a custom frame).  But this is very important - you must provide us with saddle height, reach, drop, (and the seat angle for the frame for which these numbers "work" for you) that you need your new frame to be able to achieve.  You can even give us a range.  But we can not "guess" for you what the optimal numbers may be or make accurate judgements if you say I have a race bike but I want to be more upright.  We urge you to test out the contact points you want for your new bike on your current bike (i.e if you want a more upright position, try that on your current bike to see if it works). 

 

Shop Support

Rando style bikes can be very time consuming to assemble - we are happy to provide email and phone support once you purchase a frame/fork and hopefully some parts from us so you can get it on the road.  We are also happy to chat with a local shop you may use for some of your assembly if questions arise.

 

Full bikes

In addition to frames, we sometimes sell complete bicycles, but we only schedule in a few as rando builds are very time consuming and we have limited shop resources.  As of early 2014, we are significantly over-booked and we are not commiting to any partial or complete builds at this time.  Many of our customers purchase a frame/fork and perhaps some special rando parts from us, and either assemble it themselves or patronize their local bicycle shop for the build.  This is an ideal choice for the customer that wants the frame and specialized parts that are unique to us, yet needs the support and assistance of their local shop.  We are also working on more technical info that we will post to this website that will provide buyers and other shops with the info they need to build up one of our bicycles (well not all the info, we can't post everything but we will get the main points covered soon we hope).

Sizing Information

Click Here for a PDF illustrating these measurements

When we size a bicycle for someone, we like to get three pieces of information.  This information is easiest if supplied in metric - plus the charts below can help also!

1)   Saddle height.  On a bicycle that fits well, get the measurement from center of crank to top of saddle.

2)   Reach.  This is simple but the hardest to explain.  Look at the bike from the side. Now consider the line going through the center axis of the seatube, then it extends through the center of the seatpost, and then continues until it "pierces" the top of the saddle.  From the point where the top of the saddle is "pierced" by this imaginary line to the top center of the handlebars is the Reach.

3)   Saddle to bar drop.  Also known as the difference in height between the bars and the saddle.  It is easiest to measure by taking the measurement from ground to top of saddle, then ground to top of bars, then subtract the difference.  Then be sure to make a note which of these is higher. Usually the bars are lower than the saddle, but that is not always the case, especially on rando oriented machines.

Now, if your reference bike doesn't fit well, or if the seatangle of your bike is not "typical", or if you are using a post with extra setback (or no setback), please let us know.  But as a rough guide, these numbers work really well for dialing in the fit on the vast majority of riders who are comfortable and set up well on their current bikes.
