Over the past several months, some changes in my cycling ways have been quietly taking place. I have hinted at it, but I don't think I have fully disclosed just how serious I've been getting about road cycling. Little by little, regular 20 mile rides turned into regular 30 mile rides and now, time permitting, regular 40 mile rides. I have found that I truly enjoy cycling on a roadbike and I want to see how far I can go with this unexpected passion. I don't feel the need to write about most of my sporty rides just as I don't feel the need to write about every time I commute - but it's happening, and the proportion of miles I spend cycling for transportation versus sport is probably about 1 to 5 at the moment. As a reflection of this, I have made some updates to my bicycle holdings - which I will describe in abundant detail in posts to come. And the flip side to those updates, is... well, the necessity of the Lovely Bicycle Bike Sale, as the title of this post suggests. The "sale" is actually just two bikes. But they are very nice ones and they have been good friends to me. If you are interested, please drop me a line at filigreevelo-at-yahoo. Deep breath, and here we go:

5-Speed Conversion!
My conversion of the Mercier mixte to a 5-speed is pretty much complete, and it worked out nicely. I've received some questions about the process since I first mentioned my plan to do this, so I include answers to these questions here.
What is a 5-Speed Conversion?
A 5-speed conversion refers to transforming a vintage 10-speed bicycle into a 5-speed by removing one of the two front chainrings and the front derailleur system (see before and after pictures above). In the end, the bicycle is left with a much simpler set-up of 5 chainrings in the rear, 1 chainring in the front, and a single gear shifter. It works much the same as a 5-speed hub, only the gears are visible rather than hidden inside the hub.
Why do this? Doesn't it mean you have fewer speeds now?
Hard question to answer, but I will try: The advantage of a derailleur over an internal hub, is that it allows for much wider spaced gearing. Riding the Mercier around hilly areas, I can get by perfectly well with just the middle 3 rear gears. The 2 extra rear chainrings provide a nice "just in case" buffer of one higher and one lower gear than I'd ever need, but the second front ring (which provides 5 additional speeds) and the whole front derailleur system (which switches between the two front rings) are useless entirely in the context of where and how I plan to ride this bike. Given my certainty of this, converting it to a 5-speed made sense, because it would simplify the handling of the bicycle and it would get rid of extraneous components. Also, this bike (as many older French bicycles) was originally designed to have a rear-only derailleur system. This is evident, because it has a braze-on (on the downtube) for just a single gear shifter. So converting it to a 5-speed reverts to a traditional design.
If you're going to make it a 5-speed, why not use a 5-speed hub and ditch the derailleur system all together?
The main reason, is that no existing 5-speed hub could give me the same customised, wide spacing as a 5-speed rear derailleur. It's not just about how many speeds you have, but how useful each of those speeds are. Additionally, it would cost a ton of money to rebuild the rear wheel with a 5-speed hub, whereas the 5-speed derailleur conversion was inexpensive. And finally, I am trying to keep this bicycle fitted with traditional components, and French bicycles were traditionally fitted with derailleurs.
How was the conversion done?
Keeping in mind that the process will differ depending on your current set-up, here is what generally needs to be done, step-by-step:
1. Front chainring removal
Since you will only have one chainring in the front now, you need to figure out how to get rid of the second one. The main issue here has to do with how the crank arm is attached to the ring(s). On some bicycles, it is possible to simply remove the extraneous chainring and the remaining chainring will hold up the crank. On my Mercier, the two rings are a unit, attached to the crank via a proprietary bolt system. To make a long story short, we could not simply remove the extra ring. Rather than get an entire new chainring and crank system, it occured to me that perhaps the teeth on the bigger chainring could be filed off - turning the ring into a chainguard. I discussed the idea with metalworker and bicycle mechanic Jon Gehman, who is a reader of this blog, and he agreed that this was a good way to go. I then sent him the chainring for a "de-toothing" service, and he did a spectacular job.
Here is a close-up of what was formerly the larger chainring. Notice how beautifully the edge is done - giving it a professionally finished look.
2. Front derailleur removal
This was the easiest part. The Simplex front derailleur simply unbolts and removes. On the picture above you can see that the rainbow decal is a little worn where it used to be, but that is all.
3. Changing the shifters
The ease or difficulty of this step depends entirely on what sort of shifters you have to begin with. If your bicycle has separate (unconnected) shifters for the rear and front derailleurs, then you simply remove the one that controls the front and you are done. If your shifters are a unit, then you will have to remove them and install a single shifter instead. Above is a vintage Huret single shifter for mounting on the stem that I bought for this purpose. It's beautiful, "period-correct", and can be bought fairly inexpensively. The Co-Habitant installed the shifter and connected the cable to the derailleur.
Here is the Huret shifter installed on the stem. I am not 100% sure though that this is the ultimate solution. Originally, the Mercier had downtube shifters, and this is where the single braze-on is located. However, I do not understand how one is supposed to use downtube shifters on a near-upright bicycle. At least for me, and in traffic, they were too much to handle - especially given that the shifting has to be done with the right hand.
So now there is a cable stopper where the downtube braze-on is, and the cable then extends further to the stem. Though the Huret shifter is beautiful on its own, I am not sure how fitting it is here. For instance, the reason it is not all the way at the bottom of the stem, is that placing it here makes it hit the handlebar when it is moved all the way forward. Hmm, right? Your thoughts on this welcome.
Overall I am thrilled with the 5-speed conversion. The Mercier is light, easier than ever to handle, and now ready for its fate as Studio Bike. I admit that I am reluctant to send it over to the Studio and quite like having it here at home. But I also look forward to exploring a new neighborhood together... and to having less bike clutter in our apartment!

Velo Purgatory
People who have lots of unfinished bike projects lying around must be used to this - but to me there is something sad and anxiety-provoking about having a bike at home that's missing parts, or a frame that has not had a chance to become a bicycle yet. It's as if the non-functional bicycles are in a state of velo-purgatory - crying out to be completed and ridden.
My beautiful Royal H. mixte frame came home today, and it looks like I will be building it up much later than I thought - possibly in the end of the summer, or whenever I manage to save the money. And my attempt to tackle the Sam Hillborne frame on my own over the winter did not end well. In the end I brought the frame back to Harris with the metaphorical tail between my legs, and it is only now being built up - in the very midst of the spring customer rush. Naturally, having a bicycle built at a shop is more expensive than doing it oneself, and so my plans for the Royal H. mixte are on hold until some serious financial recovery time after the Hillborne. In the meantime, I better wrap it in bubble-wrap and put it away. I don't think it's healthy to sit on the bed next to a bicycle frame and stare at it for this long.
My Mercier mixte is now also a "purgatory bike", albeit very temporarily. The large chainring is off getting "de-toothed" by a fine gentleman who is a reader of this blog, as part of my scheme to convert this bicycle to a 5-speed. The chainring will be back soon, and till then I respond to the Mercier's questioning glances by gently stroking its handlebars and assuring it that it is not being disassembled for parts but is being improved.
Ah the joys of obsessiveness, anthropomorphic tendencies and an overly vivid imagination!

Oh, This Old Thing?
The Co-Habitant teases me for my tendency to love decrepit old bicycles despite having modern options. My Mercier in particular is not only old, but quite crusty - with dulled paint, visible rust, and various other signs of wear. And yet this bicycle is so comfortable and charming, that I have been on an obsessive quest to make it "perfect" in its own unique way.
Pictured here are my latest additions: fenders, front rack, bell, and stem shifters.
For fenders, I chose the inexpensive stainless steel fenders from Velo Orange. The idea (aside from saving money) was that the plain polished fenders would go nicely with all the chrome parts on this bicycle. I think it worked out well.
And this is the tiny, adorable vintage TA front rack, designed to attach to the Mafac brakes on the Mercier. These come up for sale occasionally online and from fellow collectors at reasonable prices.
The rack, while very cute, is so small that I am not sure what I will put on it. A classic touring handlebar bag does not really fit the look of this bike, but I will keep thinking. What did the French put on bicycles with these handlebars?
Finally, we replaced the original Simplex downtube shifters with Suntour stem shifters (this part was done at Harris Cyclery, while the fender and rack installation we did at home). Downtube shifters just did not seem appropriate for this bicycle and reaching all the way down there in traffic did not feel safe. The little stem shifters are perfectly placed and very easy to operate.
In addition, I have begun converting the Mercier to a 5-speed - so the left shifter (leading to the front derailleur) is no longer connected to anything. The left shifter and front derailleur will come off once I get the situation completely sorted, and a vintage French chainguard will be installed. I will explain why and how I am doing this in a separate post - but hopefully it will work out.
All of this does sound like a lot of fuss about an old bike. But in a way, it is the Mercier's decrepitude that liberates me: Had the original paint been in better condition, I would not have dared re-paint the lugs by hand to this nice green-gray from the original black. Had the components been higher-end, I would not have been willing to experiment with a 5-speed conversion. There is a lot of fun to be had with an old bicycle. The main thing, is that you like the ride quality and care enough to gradually improve the rest.

Another Season... Another Vintage Bike?
"Many higher-quality French bicycles of the '70's came with AVA brand bars and stems. These have a reputation for failure, and should be replaced if the bike is to be ridden hard or fast."Hmmm... "higher quality" and "failure" in the same sentence? Should I interpret this to mean that as long as I don't race on the bike, the AVA stem will be okay? That is how I would like to interpret it. Advice welcome.
So, I am considering doing one of the following:
A. Cannibalizing the better components from the Motobecane (derailleur, shifters, and - is this possible? - wheels) and building up the Mercier as my perfect vintage mixte. Then sell off the Motobecane for cheap.
B. Converting the Mercier to a single speed, or possibly even fixed gear (you know, to practice for the velodrome). This should be relatively easy and unintrusive, given that it has clamp-on derailleur and shifters, and compatible drop-outs.
Any opinions and advice regarding these options would be much appreciated!
