I Christen Thee Negrosa

Finally!  She's together!

No, that's not what someone said about me after I figured it all out.  (As if I ever did!)  I'm talking about...another bike.  I mean, what else could I be talking about on this blog, right?




Specifically, I'm referring to the 1973 Mercian Olympic (I mistakenly identified it earlier as a King of Mercia; Grant at Mercian confirmed that it's an Olympic) I bought in June.  The funny thing is that I didn't have to do much to it, but it took me longer to finish than it took to get Dee-Lilah, my new Mercian Vincitore Special, ready after the frame arrived.




In the case of Dee-Lilah,  I had all of the parts, and Eli (of Ruth SF Works) made a couple of bags for me and once Hal put it all together, it was ready to go.  I haven't found any need to adjust or change anything yet.

On the other hand, for the Olympic, I had to look for a couple of things, and make a couple of other choices. 

Right from the beginning, I replaced the tires, which were cheap and mismatched, with a pair of Continental Grand Prix 4 Seasons.  I also swapped out the SunTour freewheel for another SunTour--the ProCompe  that came with the bike (and is now on another) for a New Winner--and the unknown-brand chain for a Sedisport that'd been in its package for 30+ years.

Old Cinelli logo.

After a couple of rides, I knew I wanted to change the stem from the 9 mm extension that came with it to a 10.  The stem and bars that came with the bike were Cinellis, in the old 26.4mm clamp diameter.  I like the bars, so I didn't want to buy new ones.  That meant looking for a stem in the proper diameter.  I also wanted to find one that had the old-style oval logo, like the one that came with the bike, but had no luck there.  Oh, well.  Cinelli has never produced an ugly logo, so I don't mind having the newer one.  Besides, the logo switch seems to have been made not long after the frame was built.

Now, stems before the 1990s didn't have "faceplate" clamps.  So, if you want to switch stems, you have to unwrap the bar tape.  I didn't mind, as the tape that came with the bike was a mess:  It was faded and felt as if it had been epoxied onto the bars.  And the rubber hoods were disintegrating on the brake levers.

Luckily for me, I managed to find a pair of original-style Campagnolo gum hoods for not much more than they cost 40 years ago.  Best of all, they were fresh and supple.  As for the tape, I decided to go with something basic but classy:  black Tressostar cloth tape.  I spiced it up a bit, though, with red bar plugs.




To match those plugs--and the red parts of the frame--I found some vintage red Christophe straps.  And the one truly unsightly part of the bike as I got it--apart from the brake hoods and tape--were the toe clips, which were rusted and pitted even though nothing else on the bike was.  They were from "Cycle Pro", which offered some decent stuff back in the day.  But, since we're talking about a vintage Mercian with Campagnolo parts, I thought only Christophe clips would do.  And they're what I put on those Campy pedals.




Now, of course, we all know that we really make our bikes our own with accessories.  I could have sworn I had a Silca frame pump somewhere--but I couldn't find it for the life of me.  Oh, well.  Hal had one, but it looked like hell.  He made a suggestion:  a Zefal HP or HPX.  I just happened to have one in the latter, in just the right size.  And, while it's probably from the 80s or even later, it looks good, if not period-perfect, on the frame.







And, yes, that's a real, live Specialites TA cage on the handlebars.  Like the brake hoods, it was in pristine condition before I mounted it.  I found, though, that I needed to use longer screws than the ones that came with the clamp.  I have a feeling they were designed for old French handlebars, which are narrower at the "sleeve" area than my Cinellis.


Yes, the bike came with that saddle!


The bag is from Acorn.  I have another, larger, black bag that Eli made.  

Even with those minor changes, I still can't believe my luck in finding that bike--with a Brooks Professional saddle in perfect condition, no less.  And so soon after getting Dee-Lilah:  It was like getting two birthday presents!




After accessorizing, there's one more thing you (or I, anyway) have to do in order to make your (my) bike your (my) own: name it.  So, after putting that bottle cage on the handlebars, I christened her Negrosa. 

Now I really have decisions to make whenever I go out for a ride:  Dee-Lilah, Negrosa, Tosca (my Mercian fixed-gear), Arielle (my Mercian Audax) or Vera (my Mercian mixte).

Does Nobike Fit All?

So why do you have six bikes?

If you have more than one bike, you have heard some variant of this question--from a spouse, lover, other family member, co-worker or friend who doesn't share your enthusiasm for cycling.  That person might see that one of your bikes has drop bars and the other has uprights or flats.  Or he or she might notice that one bike has fatter or skinnier tires, or has only one gear or multiple gears.  On the other hand, that person might see only that your bikes are different colors or have different names on them.

The reason nearly all of us give--if we actually ride the bikes we own (I do) is that they have different ride characteristics.  One bike might be better for long distances, another for speed and yet another for "rough stuff".  One of our steeds might carry our groceries, books r even furniture, while another can and should be ridden only in its most stripped-down form.

Now, if you've gotten this far in answering your incredulous friend or lover, he or she might ask whether there's one bike that can "do it all".  Some bikes are billed, by their makers or marketers, as Swiss Army knives on wheels, if you will.  Swiss Army knives are great (I have a couple.) and they can perform a number of different tasks in a pinch.  But, for most of those tasks, if you had to do them every day, you probably wouldn't want to rely on your Swiss Army knife.

Still, it seems that there's always someone trying to create a bike that can give a satisfying ride in all conditions.  Likewise, it seems that there's always someone or another who's trying to design a bike that will fit everyone.  Nearly every folding bike I've ever seen is touted as a machine that will fit everyone from about 150 to 215 cm (a little less than five feet to a little more than seven feet) tall.

When you've been riding for as long as I've been riding, you become skeptical about either endeavor.  So, it might seem doubly dubious when you hear that someone has designed a bike that not only can be adjusted to a wide range of sizes, but can also be altered to suit different riding styles and conditions.



Well, Dynalab has just designed such a machine. The frame is made from four triangular slabs of aluminum slotted together by three joints with cylinder spacers.



According to the folks at Dynalab, the frame has 80 cm (about 31.5 inches) of vertical adjustability, making it "suitable for men, women adolescents and adults alike".  The aluminum slabs can also be moved horizontally and the angles varied to change the frame's geometry.



The bike actually sounds interesting and I wouldn't mind trying one, if only out of curiosity.  If it works, I could see using it as a travel bike, as it looks as if it could be disassembled rather easily and carried in a relatively small piece of luggage.  And it could be made into whatever kind of bike would suit the conditions you might encounter upon arrival.  

Even if the ride and fit qualities are as good as Dynalab claims, I have to wonder how sturdy those slotted joints are. Just how much assembling, disassembling and moving around could the withstand?  And how much shock and abuse.

Still, even if it is what it's claimed to be, I might have a hard time shelling out my money for something called Nobike.
