As a gigantic birthday present for turning 60, I bought myself a Lemond Prolog all-carbon e-bike. It is a beauty. And it handles like buttah.
However, in the years since buying it, I haven’t been riding it much. Why not? Insert your favorite reasons here, adding side helpings of lack-of-fitness shame and anxiety, and that pretty much explains it.
This year I’ve been cautiously venturing out of my inertial state of less activity and taking some steps and strokes and stretches, experiencing what movement has to offer me. A bit of yoga, some walking, some swimming, and yes, some cycling– they are all back on my schedule in modest portions.
And then there is the matter of this bike. I’m somewhat handy with easy maintenance and repair (with a lot of help from friends), but this bike is different from my previous ones. It has thru axle rather than quick-release wheels. Also it has disc brakes, and there’s a motor cable connected to the rear wheel. All this means I have to relearn how to change tubes on this bike.
So I began that journey this week. I went to my LBS (local bike shop) to get the right tubes (this bike has 38mm tires). Check. And I have the necessary 6mm and 8mm hex wrenches for loosening the front and rear thru axles, respectively (why different sizes? Only Greg Lemond knows; or maybe some of you do, too?) Check.
But (and it’s a big but): some of the internet recommends that I use a torque wrench (with 6mm and 8mm bits) to tighten the wheels. Uh, okay.
But what kind of torque wrench? I learned that I can buy a cheap one at Home Depot for $35, or a fancy one at the LBS for $240. Hmmm. And do I REALLY need the torque wrench for tightening the wheels? Yes, it’s an all carbon bike, and cracking the carbon by overtightening would be a world-ending (or rather, frame-ending) scenario. But can I just be careful while tightening them, making them not to loose but not too tight? In other words, can I get it juuuust riiight?
Given that I received mixed messages about torque wrench usage, I turned to friends and nice employees at the LBS. The consensus seems to be that while, yes, the torque wrench is recommended, and several people I know actually own one , they don’t actually use them for changing out tubes and tightening wheels. They’re all happy to lend me theirs.
Okay. I get the picture. So, all that remains is to bring up my bike stand from the basement and practice a bit so I can be comfortable changing a tube on the side of the road if need be. I’ve got my saddle back fully stocked with the right tubes and tools.
One more thing: I really like this e-bike, but in fact it doesn’t fit me like a glove the way my other bikes do. And I thought I was stuck with this configuration, as it has a monocoque (one-piece) cockpit (handlebar plus stem setup). So, it can’t be adjusted.
Or can it? The nice folks at my LBS (Belmont Wheelworks if anyone is interested) said it might be possible to change out the steerer tube (yes, I’m getting very bike wonky here, but will be done soon) to adjust the height of the handlebars. Or, I can go full Frankenbike and put on my own handlebars, stem, etc. (with the help of the kind LBS-ers). I will be exploring my options and will report back on the results.
In summary: I’m getting to know my e-bike much more intimately, and the two of us will make adjustments so we can ride along more happily together. Which is all we both ever wanted in the first place.
