I just saw a Boston Globe arti­cle in which cycling advo­ca­cy groups are demand­ing that 18-wheel trucks be banned from the city after yet anoth­er cyclist fatal­i­ty caused by a turn­ing truck.

I think this is a great idea, but cycling safe­ty shouldn’t be the only moti­va­tion. I have always been annoyed at how waste­ful and ridicu­lous it is to have enor­mous diesel semis roar­ing through com­pact city streets to cov­er rel­a­tive­ly short dis­tances with small amounts of car­go. Star­bucks uses 53′ trail­ers to deliv­er cof­fee and cups to their stores, for exam­ple. Real­ly, you couldn’t do that with a light­weight van?

I’m sure that with all the con­struc­tion in town, an absolute ban is not fea­si­ble, but there’s no rea­son we couldn’t head the direc­tion of more pro­gres­sive cities like Oslo and Paris by requir­ing that deliv­ery vehi­cles get small­er, lighter, and more elec­tric.

pedal-wood-03-pair File this one under “first-world prob­lems.” Since putting togeth­er my belt-dri­ve city bike last fall, I have been look­ing for a bet­ter way to ride (occa­sion­al­ly) with nice leather-soled shoes. Every met­al- and plas­tic-sur­faced ped­al I tried rubbed uneven­ly against the shoe, destruc­tive­ly dug into the leather sole with sharp points, or both.

The solu­tion seemed to come in the form of the Moto Urban Ped­al, which has an unusu­al­ly large flat fric­tion sur­face as well as a dis­tinc­tive ply­wood body. Unfor­tu­nate­ly, the fric­tion is pro­vid­ed by “strong grip tape.” While their adver­tised claim is true–that the skate­board-style grip tape pro­vides slip-free con­tact even with wet leather soles–the man­u­fac­tur­er doesn’t men­tion that grip tape also destroys leather by grind­ing it down. As I found out, grip tape is just coarse sand­pa­per with an adhe­sive back­ing. That solu­tion is per­fect for the skate­board-indus­tri­al com­plex because it ensures a steady cycle of demand for new skate­board­ing shoes, but it is unsuit­able for my needs.

So I began my Edi­son-style exper­i­ment with every kind of fric­tion mate­r­i­al I could get my hands on. I tried sev­er­al dif­fer­ent mod­els of 3M Grip­ping Mate­r­i­al, the amaz­ing stuff that sim­u­lates gecko feet, but it quick­ly became clogged with debris. I tried a tex­tured self-adhe­sive neo­prene prod­uct designed for guns (?!), but it lacked the dura­bil­i­ty and adhe­sive strength I need­ed.

Final­ly, Feld­meier sug­gest­ed that the best fric­tion mate­r­i­al for shoes might be anoth­er shoe. From an online cob­bler sup­pli­er, I obtained two sheets of sol­ing mate­r­i­al: a 2 mm SoleTech sol­ing sheet for dress shoes and a 4 mm sheet of Vibram 7175 boot rub­ber. The Vibram mate­r­i­al is amaz­ing but way too thick and heavy for this appli­ca­tion, so I put it aside. The SoleTech (check-tex­tured SBR rub­ber) is per­fect.

I made a tem­plate of laser-cut acrylic so I could cut per­fect ped­al-shaped pieces from the sheet with a knife.

Rub­ber con­tact cement pro­vides a per­fect (although pos­si­bly too per­ma­nent) bond to the plas­tic pieces that form the plain bear­ings in the Moto ped­als. It also smells awe­some.

2014-09-14 11.41.37

The new ped­al sur­faces are work­ing great so far, wet and dry. And they don’t destroy leather. We’ll see how they hold up in the long term.

Hill climb gearing

July 18 was my one oppor­tu­ni­ty to attempt Mt. Wash­ing­ton by bicy­cle before race day. I had a cou­ple of goals in mind: find­ing a rea­son­able pace and test­ing my hill-climb set­up.

It’s worth point­ing out that the ride is much too steep and long for con­ven­tion­al road bike gear­ing to make sense—an effi­cient cadence would not be pos­si­ble. It seems like every­one has an opin­ion about what makes a per­fect set­up. Some peo­ple run with a road triple crankset up front, or maybe a com­pact crank. Some peo­ple install a moun­tain cas­sette on the rear wheel, which usu­al­ly requires a long-cage moun­tain derailleur to go with it. Since I have only one road bike, and re-tun­ing derailleurs is not my idea of a great time, I came up with a dif­fer­ent con­fig­u­ra­tion: a moun­tain crankset, hold­ing only a 22T chain­ring on the front, and a con­ven­tion­al 12–25T road cas­sette (and stan­dard derailleur) on the back. With this set­up, I can achieve bet­ter than a 1:1 gear ratio. And the only parts I have to swap out are the cranks, bot­tom brack­et, and chain! (Shame on Shi­mano for mak­ing road and moun­tain bot­tom brack­ets very slight­ly dif­fer­ent.) One unfor­tu­nate con­se­quence of hav­ing the bike con­fig­ured for hill-climb­ing is that my top speed on lev­el ground becomes about 8 MPH, which can be embarass­ing if you’re actu­al­ly try­ing to get some­where.

We stayed at a friend’s cab­in in Tam­worth, then drove up at the crack of dawn. There aren’t many oppor­tu­ni­ties to catch me awake and alert at 5:30 AM, but this was one, as the road would close to bikes after 7:00. Bad news greet­ed us upon our arrival, though: in spite of the stun­ning sun­rise and pic­ture-per­fect weath­er on the ground, the course was closed due to high winds. Above tree­line there was a steady 55 MPH breeze gust­ing to 70. Appar­ent­ly they will run the race in winds up to 45 MPH, but beyond that appar­ent­ly peo­ple have dif­fi­cul­ty stay­ing upright. After much moan­ing and groan­ing and re-check­ing of wind speeds, it was deter­mined that we would be allowed to ride only the first two miles of the auto road. So up we went. It was the hard­est two miles I’ve ever biked! At least there was a bonus: we were per­mit­ted the unusu­al oppor­tu­ni­ty to ride our bikes back down. Wheeee!

After all the bikes had cleared the course, the auto road opened to cars. We paid the toll and drove to the top so I could study the route. Check out the day’s pic­tures here. As you can see, the weath­er above tree­line is just as intim­i­dat­ing as the slope of the road!

One of my “res­o­lu­tions” for 2010 was to join a cycling team and start rac­ing. I have fall­en a lit­tle short on that task: although I trained all win­ter and even took a bike rac­ing class, my sum­mer sched­ule filled up so quick­ly that join­ing a team start­ed to seem like a waste of mon­ey. But months ago, when snow was still falling and every­thing seemed pos­si­ble, I seized upon a moment of mid-win­ter hubris and signed myself up for one epic race: The Mount Wash­ing­ton Auto Road Bicy­cle Hill­climb.

For some back­ground, let’s turn to a descrip­tion of the course from a Sep­tem­ber 2004 arti­cle in Out­side mag­a­zine:

The Rock­pile, as Mount Wash­ing­ton is unro­man­ti­cal­ly nick­named, tow­ers 6,288 feet above sea lev­el. We’ll be climb­ing the upper­most 4,727 feet, over a mere 7.6 miles. (For per­spec­tive, one of the tough­est races in the Rock­ies, the Mount Evans hill climb, near Den­ver, ris­es 7,000 feet over 28 miles.) With an aver­age grade of 12 per­cent and sus­tained stretch­es of 18 per­cent (high­way grades rarely exceed 7 per­cent), Mount Wash­ing­ton is steep­er than L’Alpe d’Huez or any oth­er climb in the Tour de France, Spain’s Vuelta, or the Giro d’Italia. Mile for mile, it is arguably the tough­est one-day bike race on the plan­et.

There are a whop­ping 72 turns on the Auto Road course, and the longest straight­away is only a few hun­dred yards—on dirt. Most hill climbs ease off at the top, allow­ing rid­ers to drop into a more mus­cu­lar gear and enjoy a burst of accel­er­a­tion. Not on Wash­ing­ton. In the final 100 yards—a sec­tion alter­nate­ly called the Corkscrew, the Lad­der, and the Wall—the grade steep­ens to a hor­ri­fy­ing 22 per­cent.

So there it is. Why did I sign myself up for this again? It’s true that I enjoy rid­ing on hills. And I do score rea­son­ably well on that gold­en met­ric of hill­climbers, watts per kilo­gram of body weight. But this is start­ing to sound a lit­tle intim­i­dat­ing. There’s no coast­ing: if you stop ped­al­ing on this hill, you’ll fall off the bike. And at a “race pace” of 5–6 MPH, draft­ing isn’t much use either. Will I even be able to eat or drink? Will my cus­tom hill­climb gear­ing pro­vide the right ratios for effi­cient rid­ing?

The Mt. Wash­ing­ton Auto Road is not nor­mal­ly open to bicy­cles, but to help answer some of these ques­tions, the orga­niz­ers allow for one unsup­port­ed prac­tice ride a month before the race. And with the actu­al race com­ing up on August 21, that prac­tice ride is hap­pen­ing this Sun­day. More to come!

Wells Ave 2010-05-02

As I have men­tioned, I’m try­ing a new sport for 2010: bike rac­ing. For this rea­son, I enthu­si­as­ti­cal­ly took to April’s NEBC Spring Rac­ing Clin­ic, even when that meant rent­ing cars every Sat­ur­day and dri­ving all the way to Fort Devens. While the pace of the class was a lit­tle uneven, it was com­plete­ly worth­while. Two drills took me most out­side my com­fort zone: the water bot­tle pick-up drill and high-speed cor­ner­ing.

“Grad­u­a­tion” was par­tic­i­pa­tion in the Wells Ave Train­ing Cri­teri­um on May 2. A cri­teri­um is a short race involv­ing many laps around closed-off streets. This for­mat is ide­al for spec­ta­tors! For us begin­ners, the total dis­tance is only 12 miles (15 laps), and it goes by fast! My bike com­put­er record­ed an aver­age speed of 23.6 mph. The class­es pre­pared me well, but I also fol­lowed the last-minute advice of an expe­ri­enced bystander: stay to the front and the out­side to avoid crash­es. Good advice, I think, because there were two pret­ty bad wrecks. It’s dif­fi­cult to resist the temp­ta­tion to look at them, but there is too just much going on when you’re near­ly rub­bing han­dle­bars and wheels with a dozen oth­er peo­ple.

Wells Ave 2010-05-02 I was get­ting excit­ed about being near the front, since by the penul­ti­mate lap I had worked myself up to 3rd or 4th place. But sud­den­ly, the guys who I had been fol­low­ing dropped back, and I found myself lead­ing the last lap—with the wind in my face and legs start­ing to tire, not a great sit­u­a­tion to be in! After a sur­prise last-minute encounter with a car on the course, the fin­ish line came into view, and sud­den­ly 5 or 6 guys sling­shot­ted around me. I start­ed my sprint. It was too late to catch the guys who passed me, but I man­age to get my speed up to 36 mph, fast enough to keep the rest of the pack from pass­ing. This left me some­where in the top 10 (out of 39), close enough to feel like a suc­cess but not high enough to appear in the race results.

As we were fin­ished, an ambu­lance showed up to attend to the two crash­es. One was caused by over­lapped wheels, and anoth­er guy had been stuck on the inside of a cor­ner was trapped too close to the curb. A lit­tle scary!
circa 1992

Before rid­ing home with anoth­er Rapha-clad blog­ger-friend named Scott, we stayed to watch the first half of the B race. The speeds are a lit­tle high­er, but most impor­tant­ly, they looked so much more order­ly! I have much to learn. So I’m moti­vat­ed to find a team. And to keep train­ing for my big race in August, which I will write more about in a sep­a­rate post.

Also: it is con­firmed that the Igle­heart road bike I got last year rocks!

I recent­ly found this pic­ture of me at age 12. It’s fun­ny that it took me so
many years to dis­cov­er this sport, since appar­ent­ly I’ve always had some enthu­si­asm for it.
