I’m happy that the Bernard Carre frame is now built up and ready for a test ride. I’m not happy to discover the rear brake is so stiff as to be nearly unusable.

I’m happy to have remembered I have been storing four brand new KoolStop “four dot” brake pads. I’m not happy realizing there’s no way to “toe in” these particular brakes and that I have to listen to the high pitched squeal until these new pads are properly seated.

I’m happy to have also remembered a Zeus Criterium “69” rear and front derailleur, and shifter. I’m not happy to discover my cool-as-shit Zeus Criterium “69” rear derailleur only wants to throw the four outbound gears, and won’t budge any further inboard regardless of how much I adjust the B limit screw.

I’m happy the frame arrived with a TA bottom bracket. I’m unhappy that the spindle is too short for my Stronglight crank.

I’m happy to discover the frame has a nice light and responsive ride quality. I’m happy to have another bike project to play around with. I’m happy to have a complete Campy gruppo to throw on in place of the Zeus kit if things don’t work out.

Hey, I’m just generally happy today.

Boulder vs. Carre

Every bike in the studio gets compared to my Boulder Brevet simply because it fits me so perfectly. It’s interesting comparing the Boulder with the Carre.

To make a fair evaluation of the geometry and size, the camera is set up on a tripod to ensure that the shooting angle and position is exactly the same between both bikes. The floor is also marked for positioning of the bikes. Because they are resting in a bike stand, some correction for “squareness” is necessary. The photos were slightly rotated in post processing so that the wheels are parallel to the picture frame. Furthermore, the Carre has been nudged so that the bottom brackets are aligned to the Boulder by superimposing the two photographs.

Here is the “control” shot of the Boulder for comparison of tube positioning, geometry, and length.

The green lines indicate a rough tracing of the Boulder tubes, which I’ve drawn on an overlay.

The overlay drawing of the Boulder tubing has been superimposed over the Carre frame. Although the wheel base is a little longer on the Boulder, and more importantly a greater difference between the lower trail Boulder fork and that of the Carre,  I was still a bit surprised to see that there’s not as much difference in bottom bracket height or drop as I’d anticipated.

With 700 x 25 tires, the standover is nearly the same as the Boulder. I anticipate running 700 x 28 so there will be some difference in the final build. It’s also worth noting that the top tube is one centimeter shorter on the Carre: 58cm as compared to 59cm on the Boulder.

This is not to say that I expect the rides to be similar. The two bikes are clearly designed for different purposes, but I’m a researcher and find it useful to compare against known factors, quantities, and considerations. My initial thinking has not changed, despite some similarities to the Boulder geometry: The Carre frame is more of a road bike design, and the available space for wider tires convinces me that it’s probably a CX model. Despite the eBay listing, I don’t see anything that screams “randonneur” to me at all.

Next up: the build.

B. Carre

Yes, I know I swore off French bikes forever. I know the objective is to thin the herd. I know I’m susceptible to the guiles of a  French beauty, especially one that’s “been around the block” more than a few times.

I also know I’m guilty of impulse purchases.

I know all of these things all too well. What I don’t know is much about this frame, and until this object of my horse trading arrives in the USA, it’s not likely I’ll know a whole lot more for a while.

Here are the facts, as I know them. This is a Bernard Carre frame. Every Carre frame I’ve seen – at least those I know for certain were built by Carre – are embossed with “B CARRE” on the seat stay caps. The frame is nominally my size at 58cm square.

I’ve no idea what tubing was used. Many French bikes of the 1970’s use a 26.4 seat pin; this one purportedly uses a 26.2.  The dropouts are spaced at 122. The frame is showing up with a TA bottom bracket. I’ll measure the spindle after it arrives to see if it matches any of my French cranks.

I’m a fan of Stronglight headsets, one of which accompanies this frame.

The dropouts are Campagnolo, as are the cable retainers along the top tube. The bottle holder appears to be a TA, or similar. The cantilever brakes are Mafac Criterium models. I’ve never used them before, but others assure me they are much easier to adjust and fine tune than earlier model cantis.

Cantilever brakes mean a couple things. For one, I’m locked in on the wheel size the frame was designed for. So if that size turns out to be a 27 inch wheel, there’s not a whole lot I can do about that. (Whereas, with center pulls or side pulls, one can often fit 700c or even 650b with a little luck.) The other thing is that cantilevers raise the question of whether or not this really is a randonneur. Cantilevers are a favored brake for cyclo-cross bikes, so the possibility is that this bike was designed for that purpose. I am leaning toward cycle-touring at the moment, but not a full bore touring model.

I’m left with a slight dilemma here: I’m in the queue for a Jeff Lyon frame. I’d planned to have that frame painted in a pale lavender or lilac color. Yet here I find myself with a frame in that color range already. Is that a problem, I wonder? (As I type these thoughts, it occurs to me that I have a pair of NOS toe straps that are the same color as this frame, just waiting for a new home. Hmmmm.)
