It's Done--I Think!

My "winter" project is more or less complete.

Back in December, I found a 1981.5 Trek 412 at an estate sale.  It was looking for a good home.  I thought I'd finish it during my January recess from school and ride it during the winter.




Well, as with almost any project, not everything went exactly as planned.  Some parts I'd intended to use didn't fit or work with other parts, and, well, I changed my mind about a couple of things along the way.

I finally got it into rideable (for my purposes, anyway) condition by Spring recess, in April.  And, as I mentioned a few days ago, gearing wasn't quite to my liking--and the crankset (which had been sitting in my parts box for I-don't-know-how-long) stripped when I tried to remove it.  So I had to "destroy it in order to save it", to paraphrase one of the more unfortunate commands of all time.

But now I think the only thing I might change is the bars--to drops. (Actually, I might make this bike "bi" and switch between drops and Porteurs as need, and whim, dictate!)




In putting the bike together, I didn't try to do an "original" or even a "period" restoration.  Instead, I tried to rebuild the bike in the spirit of the original (Yes, I know, that's an extremely elastic term!) while suiting my needs and tastes as a rider.  So, I decided not to refinish the frame (also, in part, because I didn't want to spend the time or expense) and when I didn't use parts that came with the bike, I installed components and accessories from within a few years of when the bike was made--or that at least don't look out of place on a bike of its time.




What that means is that the bike now consists of the following:

Frame and fork-- Trek 412, of Ishiwata 022 tubing.

Headset--  Stronglight A9 roller bearing (came with frame)

Wheels--   Rear:  Specialized sealed bearing hub (made by                                       Sansin) sealed bearing 
                          Sun CR 18 Rim, 700C
                          36 DT spokes, 2.0 straight gauge, 3 cross
                
                  Front:  Suzue sealed bearing hub
                           Sun CR 18 rim, 700 C
                           36 Wheelsmith spokes, 2.0 straight gauge,                                3 cross

                  Continental Gatorskin Hardshell tires, 700 X 32

Crankset--   Shimano A 124 triple (1986 model), triple
                            46/42/28 rings

Derailleurs-- Rear:  SunTour VxS with sealed pulleys
                    Front:  SunTour Spirt (top-normal)
                    Shifters:  SunTour PD-M (racheted)

Freewheel--  SunTour Winner Pro five-speed, 13-26

Chain--         SRAM PC-830

Pedals--        MKS GR-10 Platform (like Lyotard Berthet)
                    MKS "Basket" toe clips
                    Generic leather toe straps

Brakes--        Weinmann Carrera (first version)
                       with Mathauser "Kool Stop" pads
                  
                    Tektro 4.1 inverse levers 

Handlebar--    Velo Orange Porteur 

Stem--           Specialized 9mm, made in Japan (Nitto?)

Seat post--     SR Laprade alloy (came with frame)

Saddle--         Brooks B17

Fenders--       Velo Orange Hammered, 45mm, with flap                              from RuthWorks SF

Rear Rack--     Blackburn Expedition stainless steel

Front Rack--    Nitto M18.

Bottle Cages--  Twofish

Pump--            Zefal Competition, converted

I plan to put a decaleur made by Mark Guglielmana on the stem.  I've been using it on Vera (my Mercian mixte) and like it a lot.  The reason I want to shift it to the Trek is that there isn't enough room under the headset nut for a decaleur (or anything besides a headset spacer).  The Stronglight A9 that came with this bike isn't the original:  Apparently, the original (probably Japanese) had a smaller stack height.  Moving the decaleur will allow me to use my RuthWorks Randonneur bag on this bike.

Rebuilding this bike has been an interesting--and so far worthwhile--experience!

A Trek Through The Heat Wave

The weather has been so strange this year.   February was warmer than April (or so it seemed), and after a spell of summer-like heat and sun in the middle of last month, skies turned gray and the air as chilly as that of early spring.  Now we are experiencing a heat wave:  For the third day in a row, the temperature topped 90F (32C).  

So I packed a mini-picnic lunch and rode to the most logical place:  the water--to the ocean, to be more exact.  I took a familiar route down to Rockaway Beach and along the south shore of Queens and Brooklyn to Coney Island, and along the Verrazano Narrows and East River back to my place.  In all, I did about 85 kilometers of riding.



And I took my winter-project Trek for the ride.  I've made a couple of changes on it, both of which turned out for the better.

For one thing, I converted the double chainring setup to a triple.  Actually, the crank is made for triples, but I had originally used  "Gran Fondo" 46/30 gearing on it, with a 46 in the middle position and a BBG bashguard/chainguard replacing the outer chainring.  



After a couple of rides, I remember why we used to ride half-step gearing.   If you ride, say, a 12-25 or even a 12-27 nine-speed cassette, the differences between the gears aren't nearly as great as they are on almost any five-speed freewheel, except for the "corncob"  (a.k.a. "straight block) ratio--which, at my age and given the fact that I'm long past racing, I will never use.



As it happens, I've been riding a 12-25 nine-speed on Arielle, my Mercian Audax.  On the other hand, the Trek now has a 13-26 five-speed freewheel, with between-gear gaps nearly twice as wide as those on the nine-speed cassette.  So, the 46 tooth chainring gives a 3.54 ratio (or, a 95.5 gear), while the next cog--15 tooth--provides a ratio of 3.06 (82.8).  I find ratios in the 3.2 to 3.4 range very useful--at least, that's what I often ride on Arielle (48 tooth chainring with 15- or 14-tooth cog).  



Now, I know the Trek is inherently a heavier bike with somewhat more relaxed geometery, and that I've added racks and fenders to it.  Still, I missed having gears in the 3.2 to 3.4 range.  So, I added a third chainring to the front:  a 42 tooth in the middle, with the 46 tooth in the outer position.  



Now it will just be a matter of re-acclimating myself to more frequent front shifts than I've become accustomed to making.  On Arielle, and even on Vera, my Mercian mixte (which has a 46-30 setup), I almost always ride the larger chainring.  



The other change I've made to the Trek is the brakes.  The Weinmann 605s, especially with the Mathauser Kool-Stop pads, were fine.  But I got a good buy on a lightly-used set of Weinmann Carreras.  I noticed the difference (also with Mathauser Kool-Stop pads) immediately:  The Carreras have a firmer, more positive, feel.  I think it's mainly a result of their beefier arms.  Next to the 605s, they're a bit clunky. But the Carreras have a nice finish, which looks especially good next to the hammered fenders, I think.



I may make one more change to this Trek.  I like the way they look with the Velo Orange Porteur bars, but I get the feeling the bike is really made for dropped bars.  And, now that Helene is gone, I've thought about returning the Porteur bars to Vera.  While Vera's been fine--not surprisingly, a bit more aggressive--with dropped bars, I liked her ride with the Porteurs.  And I liked the way she looked with them, too!

Then I have to name the Trek.

Trek To The Sea

Yesterday the Trek project got another rite of initiation, if you will:  I took it on a ride I have experienced with all of my Mercians--and some of the bikes of my youth.




I pedaled down to Long Branch, NJ.   I am glad I went there yesterday, when it was overcast and windy--and turned chilly.  Today is summer-like and, of course, it is Easter Sunday, so lots of families will be taking their post-church service or pre- (or post-) prandial strolls on the boardwalk.  Some may even venture onto the beach, even though it's still  too cold for just about any land, and even most amphibious, animals to swim.




Vehicular traffic  was pretty light throughout the ride, except in one spot where it's almost always congested:  Just past the Victory Bridge, where US 9 and New Jersey Route 35 converge for a couple of miles--which is near the point where the New Jersey Turnpike (the Jersey stretch of I-95) crosses the Garden State Parkway.  But until that stretch, and after it, I didn't see many cars or trucks, even in Newark.




I rode down to the World Trade Center and descended through three levels of "upscale" (i.e., glossy and overpriced) shopping and "fine" (i.e., see above) "dining" (i.e., eating) "expriences" to the PATH train platform.  If Dante's Inferno had been made of glass, steel and faux marble, and the people spent more money for clothes with names on them but weren't really any better-dressed than I was (if I do say so myself), it would have looked like that place.




And, the train parked itself in Journal Square, about halfway through the trip, for a "schedule adjustment".  Hmm...I'll try that the next time I have a deadline to meet. Anyway, a trip that normally takes about 20 minutes took double that amount of time: longer than it took me to ride from my apartment to the World Trade Center.

Once I got out of Newark Penn Station, which smells as if someone's been brewing the same pot of coffee since the day it opened (It's a WPA building.), I was about to swing my leg over my bike when one of the most charming homeless men I've ever encountered asked me for a dollar to help him buy some fried chicken.  Who doesn't like fried chicken?  How could I deny such a request?  Certainly not I, even if he wasn't telling me the truth!




I think, subconsciously, I chose to ride the Trek today because I knew its colors would mirror, more or less, the sea and sky.  It's almost as if the Trek wanted to be there today.  






The last part of the ride--from the Azzolina Bridge to Long Branch--was the flattest and, paradoxically, the most difficult part of the ride.   It took me longer to cover that distance than to ride nearly double that distance, from the intersections of Route 35 and 36 in Matawan to the bridge.  Once I got off the bridge, I was riding right into the teeth of the wind and the temperature felt as it had dropped about twenty degrees F.  When I finally stopped, at the Long Branch boardwalk, it might been good to be a polar bear.

Speaking of which:





I think it's the first time that place has been painted in about 45 years.  My first reaction was "Uh-oh!  They're turning it into a Cold Stone Creamery clone--with CSC prices.    Turns out, I had nothing to fear.  It's still an old-school Jersey Shore roadside ice cream stand.  You won't find exotic flavors there (unless you consider Yuengling Black and Tan exotic), just the stuff you remember from your childhood.  And it's just as good, maybe better, and reasonably priced.  I ordered a cone with vanilla-chocolate twist ice cream and a cherry topping.  Definitely old-school Jersey shore.  





It was good.  Real good.  So was my ride.  So was the day.
