Trek Commuter Update

I received the Specialized Armadillo tires and mounted them on the Trek 970 commuter bike. This is not the Trek.... It's just a recent photograph with a bike frame........My tastes have evolved to the right combination conglomeration of parts and ingenuity for me, and the Trek will be very similar to my Raleigh commuter bike.

Because the Trek has no fender eyelets on the front forks, fenders may be a challenge. Also, I had to go with 26X1.95 tires, the more narrow Nimbus Armadillos were no longer available. Beach cruiser style fenders would fit. A commuter bike needs fenders, so I guess I'll fit the cut down fenders that I had on the Raleigh at first.....

This afternoon I am off to photograph a local guitarist for an album release.

Wet Armadillos

The remnants of tropical storm Fay had drenched the streets before I left work for home this afternoon. Thankfully, the precipitation had dwindled to a minimum, but the streets still glistened with an iridescent coating of water and oil.

I had been cautioned that the Specialized Nimbus Armadillo tires I had mounted on the commuter bike might not perform too well on slick streets. I was eager to try them out, so I put on my gloves and began to search out puddles and manhole covers on the way home.

I pedaled at my usual pace, not a speed demon pace by any means, but still a notch above a relaxed spin. I hesitate to estimate my speed, but it was a speed that would give me confidence regardless of the surface conditions or tires. I was thankful for the full fenders, they kept me dry as the narrow red wall rubber sliced through the water.

At the speeds I was riding, the Nimbus Armadillos were capable and certain. Transversing manhole covers, metal grates, painted sections of the pavement made no difference. Perhaps I was not going fast enough to reach the outer envelope of these tires, but then, I would not have ridden that fast anyway considering the traffic I negotiate on my commute home. If I was pedaling for time, I might have found the limits of the traction afforded. I was, however, pedaling to get home in time for dinner, hopefully before the skies dumped another deluge, without exceeding the limits of my brakes. The Specialized Nimbus Armadillos were plenty safe for that.

Armadillo by Morning

I wore gloves for the pre-dawn commute today. I suppose, as one who works with his hands in infectious situations, I should wear gloves at all times while biking. I don't though. What made this morning different was that I was running new tires for the first time. Last night, I installed the 26 X 1.5 Specialized Nimbus Armadillos on the commuter bike.

The Specialized Armadillo line of tires is a kevlar belted tire that is billed as the most flat resistant tire available. They have a reputation for being hard to install on the rim, and for being a hard riding tire. I chose them for the virtual elimination of flats though. I commute through some rough urban areas littered with broken beer and wine bottles, and I do it in the dark pre-dawn hours. I see flattened puddles of glass shards held together by battered labels sparkling menacingly in the sun on my afternoon commute back home, and I wonder how I missed them on the morning commute. With the cheap Cheng Shin knobbies I was running, I would be flatter than Daddy's wallet one day after his daughter's wedding if I were to hit one of those. Intervention was needed.

Last night, putting the Armadillos on my commuter bike's 26 inch Araya aluminum rims, I used my hands only. I had no problems at all. I put them on with a tube, and pumped them up to 60 PSI. No big deal. This morning, I left home a half hour early to give them a preliminary wringing out.

The ride was more harsh. The cheapo knobbies had a mushy quality that cushioned the bumps, cracks, potholes, and all the other uneven surfaces that make up urban commuting. They hummed going across a smooth parking lot at speed. The Armadillos were silent, and rode more roughly. On a smooth surface, I am certain they would be faster. On the city streets, the comparison was similar to a Buick LeSabre and a Jeep. The ride was more solid, as well as more certain, but you felt the effects through the seat and handlebars. Suspension in either of those areas, or both, would minimize the effects. For a rigid frame bike like mine, tighten your nuts and bolts, and consider lock washers and Loctite®.

I may decrease the inflation to 40 PSI and re-evaluate, as that is the pressure I was running in the Cheng Shins. Maybe that extra 20 pounds of pressure in each tire made for an unfair comparison. When cornering, the Specialized Nimbus Armadillos were superb. No drift, and no mushiness. The commuter bike cornered like a quarter horse. I had worn the gloves in case I bit the pavement getting around turns. I didn't need them. One experienced reader had cautioned me about wet mornings, steel grates and manhole covers with the Specialized Armadillos. I will have to put the gloves on at another time to evaluate that. This morning, they were more than adequate in holding the road through turns.

One of the unexpected fringe benefits of these tires was the more narrow width. The skinny profile allowed me to swap out my fenders to some old rusty Raleigh classic middleweight fenders I had stashed in the garage. Saying that photography helps the appearance of these relics is an understatement. They are scratched, dented, rusty, and have a Rustoleum white paint job that is battered in it's own right.Click to enlarge The black and white color scheme is as stark as a Weegee photograph.

I wanted these old fenders on the commuter bike, and the Specialized tires allowed me to install them. They give the black and white Raleigh a quality of "don't touch me" that is usually reserved for rusty barbed wire, contaminated sharps containers, and lepers in Calcutta. OSHA may require me to place a biohazard sticker on the bicycle as a result of these fenders. In the genre of bicycle uglification, my commuter package is complete. With the rattling of the fender stays over bumps and such, a bell is redundant in warning pedestrians of my approach. I installed a bell on the handlebar stem anyway.

Do I like the Specialized Nimbus Armadillos? Yes. If they live up to their billing as being virtually flat proof, they are worth the money to me. Like the $70 Kryptonite lock that makes sure my bike is still there when I get off work, this $90 set of kevlar reinforced tires is insurance that will make certain I get to work on time in an unforgiving urban environment.

Pedaling Again

The weather was fair today and I could finally bike it to work again. Rather than appreciating the luxury of air conditioned comfort, I had longed for the freedom of the bike for the past two days. The pre-dawn trip to work, when the streets are deserted is the best. If it wasn't for the perceived urgency to get to work, I would just cruise around a while at that time.

When I left work, the sun was shining, the roads were warm and the air was fresh. Perfect for a ride. The $30 Raleigh was a smooth runner and the knobby tires hummed as I sped home through the sultry heat. Tomorrow we only have a slight chance of thunderstorms, so I am looking forward to riding again. OOOOOOOOOOOOOOOOOOOOOO

When I got home, my Specialized Nimbus Armadillo tires had arrived. I'll be mounting them later this evening. It looks as though the more narrow flat resistant tires will allow me to mount the fenders I really wanted. The commuter bike will just get uglier.

After I ride on the kevlar reinforced "armadillo" rubber for a few days, I will write a short review in case anyone is interested in investing in the same tire. For me, they are cheap security that I will get to work on time.

FWIW, I measured my commute today. 11.8 miles, one way.

Tiring Thoughts

Eventually different tires will be mounted on my commuter bike. Presently it wears it's old mountain bike tires, and while serviceable, some street tires would have less rolling resistance and better braking.

Jack "Ghost Rider" Sweeney at Bike Commuters wrote an excellent article regarding commuting on a retired mountain bike. Pun intended.

After a couple of weeks researching the 'net, I decided on the tire I really want. Specialized Nimbus Armadillo tires. At $45 a tire I just tripled what I have invested in the bike itself with the tire swap. The kevlar flat protection might be worth it though.

Another option is the Specialized Hemisphere. Of course, it has "Flak Jacket" protection rather than "Armadillo".
