Why this new model?

We love our rando bikes.  But the gang at Boulder Bicycle ride other bikes types of bikes too - and we know that many of our customers have multiple bikes as well.  For many of us, a 2 hour ride at lunch or a quick century ride on a saturday morning with some of our go-fast buddies may happen under "perfect" conditions such as bright sun and no rain.  And if we need to put the bike into the car to get to a ride start (or on the roof), then a bike with fenders and lights may sometimes make a bit less sesnse. 

At the same time, the ultra light tube set that many folks seem to crave, is not ideal for some rando applications.  The combination of an upright rider on a low trail bike with a significant front load can make for a bike with a shimmy issue.  We have built enough bikes that we see it happen once in awhile.  The ultra light tubesets are not ideal for everyone on a rando machine.  But on a bike without the need for fender clearance AND without the need for a handlebar bag (and therefore a longer stem can be used), the use of the ultra light tube set can become a reasonable possibility.

Historically, very few bikes have been made that can take wide tires, have a slightly relaxed (but still what we call stage-race geometry), AND use ultra light skinny tubing.  For instance, the Boulder Bicycle gang has old Cinelli bikes that take wider 700c tires nicely, and old Team Raleigh 753 bikes that are super lively, but not one vintage bike which has both!

So in order to make bikes that we want (and which many of our customers have said they want as well), a new model was born. 

This bike is an alternative to some high-zoot pricey modern go-fast race bike.  This is the steel alternative that also happens to be priced at a fraction of what many modern frames cost.  And we bet many riders will prefer the feel of this classic lightweight steel frame regardless of cost!

Don't look at this frame and try to convert it into something else;  don't say "lets try to sneak fenders onto it" - you can't as the front center isn't long enough.  That is because this frame is designed to have a shorter top tube in conjunction with a longer stem for a specific weight distribution.  And don't try to put much weight on it - it isn't optimized for a load of any kind.  We'll probably ride this new model with a Berthoud 786 saddle bag, but nothing else. 

Instead, look at this frame as the ideal bike for a great majority of the riding that so many riders really do.  It isn't a substitute for your rando frame.  It is instead an indulgence for those who want this machine in their stable, or for those who despite the virtues of fenders are really dry-weather-in-the-daylight cyclists.  Or this new model might fill the space on the bike hook where that carbon bike you recently sold used to hang.

Now some details: (all measurements subject to production variability which although minimal does exist).

Tubing - a mix, but with skinny .7/.4/.7 top tube in small and medium sizes and .8/.5/.8 in the taller sizes

Sizes - only to about 60cm to top - larger than this and you really really should use oversize tubing.  So this model isn't for you.  There will be about 4 to 5 sizes with the maximum about 60 or 61 to top.

We've been testing this bike and it is great!  It handles a bit quicker and is more sure-footed than our bikes with similar tubing in a rando geometry.  The ride is very sweet indeed!
