How to turn an inexpensive bike computer into an expensive Cadence Meter

Getting a chance today to do something I love to do, that’s talk about the mathematics, physics, and physiology of bike riding. Today I want to do something that has not been done to my knowledge and that is to convert a cheap, or at least, inexpensive cycle odometer, speedometer, computer into a more expensive cadence meter. I’m going to do that by changing the way we do the measurement of the going around and around of the front wheel to going around and around of the pedal.

Garmin Edge 810 Software Version: 5.10

Ken from OldManRider back in Thailand. Beautiful sunny days, middle of the rainy season now which means the rains will be coming. But, it’s great because that means the forest will be crazy green, the roads are clean, and the weather is a lot cooler. It’s just a joy to ride along the mountain tops or along the river, whatever it is. Come out and join us it’s a great place.

The purpose of today is to share how to crash a Garmin Edge. This is my 810. I got it for Christmas last year. It’s a wonderful tool that I use on every ride, long and short. Besides, I need the Strava miles. But, it crashes.

Why Wear Lobster Gloves?

Last day in Michigan. Another wondrously bright, sunny day down by the lake. Following up from the last video on Lobster Gloves.

Why do we wear these crazy things? Well, it’s pretty darn simple.

A Lobster Glove is half way between a warm fuzzy mitten and a glove – a little bit of mitten at this end, a little bit of glove at that end. It just gives us extra manual dexterity but keeps us warm at the same time. So we can use the finger part to shift gears, hit the brakes, ride in whatever position that we need, and keep the rest of the hand warm.

I guess our warm weather riders just don’t know these things so we let them know.

Anyway, it’s that simple.

Getting ready to head to Thailand tomorrow. See ya there.

How to Select Good Road Bike Gloves

What to look for in a good road bike glove

I go through a lot of road bike gloves and after being road bike gloves they get recycled as my motorbike gloves. I’ve just feel “safer” wearing gloves. In the Thailand heat having non-sweating hands feels better.

I wear gloves when riding back in Northern Michigan.  When it’s cold I wear warm lobster gloves.

In my opinion, gel-filled gloves are better than gloves without padding or with simple foam padding. Gel-filled gloves are generally a bit more expensive. I’ve paid a lot and I’ve paid relatively little. Expensive does not mean good, comfortable, well made, or smart. In fact, some of the more expensive have simply stupid designs. They were obviously created by some marketing department with connections to the bicycle accessory sales chain – but not real riders.

3 Week Vegan Challenge #hclfvegan Almost #rawtill4

I just finished a 3-week vegan challenge / experiment and I want to report what I learned from the experience.

First a bit of the backstory.  Out here in Chiang Mai, Thailand we meet other road bikers as we ride the wonderful hills and local loops.  The community isn’t that big so we tend to bump into the same people quite often. On one of those chance meetings a bunch of us were invited to attend the 2016 Vegan Bike Festival.  It’s not the purpose of this post but these guys put together a health conference where the venue was at the top of the mountain and everyone is expected to ride, run, or walk there.  This is a real put-your-money-where-your-mouth-is event and that intrigued me.  Anyway, I ended up riding with the group and attending the conference every other day.  The whole thing was a positive experience.

Riding over 50: My Top Ten List

  1. I ride because I can.

Wow! Elephants!
Wow! Elephants!

While I have never been very coordinated, I was given a bike early on and I learned to ride. My body never forget that skill.

Someday I’ll be too old to ride. I’m probably more than half way there.

Right now it turns out I’m a better than average rider.

I never mastered board sports or a guitar, although I desperately wanted to be great at both. So, I ride.

  1. I ride because riding is enjoyable.

Getting on a bike brings joy. Sometimes it’s getting out. Sometimes it’s riding fast. Sometimes it’s working hard, getting sun, breathing fresh air, accomplishing a goal, being with the guys, or being alone. Sometimes it’s simply riding – and that’s better than doing nothing (or doing work). Because Punching People Is Frowned Upon

  1. I ride because riding is something I can do until I can’t.

Not the same as reason #1. Someday each of us is going to have to stop doing what we find enjoyable. I’m mainly thinking that physically getting old will eventually force me off the bike. But, responsibilities to family, friends, and work, or illness, or the seasons, or a broken bike can happen first.

Someday that thing will happen, ‘till then I ride.

  1. I ride because riding changes my body.

Interval training, aerobic zone training, stretching, and just moving all are associated with better health. Regular hard riding burns a lot of calories, builds strength all over, not just the legs, increases muscle tone, builds stamina, is heart-healthy, helps improve coordination, reduces stress, and feels good.

The day is better after a ride.

  1. I ride because riding changes my mind.

Exercise changes the mind. Humans think better when they have been exercising – regularly. Biking is a good way to exercise. Ergo, biking makes us smarter.

But, that’s not what I’m talking about. Riding, especially, fast, hard riding, either alone or in a peloton takes my entire mind. Perhaps this is what is meant by mindfulness. I don’t have extra brain cells to sing, talk to myself, or daydream. The road, cars, my legs, feet, gears, hands, breathing, heart rate, cadence, sunburn, pot holes, the saddle, and what’s happening around me are seamlessly integrated into the moment. Just a few minutes of riding like this changes the entire day.

It is good for the soul.

  1. I ride because riding is simple.

Almost any kid can ride a bike. It isn’t much more difficult for me.

  1. I ride because riding is complex.

For me, as an older rider I’m interested in getting better and more fit rather than just getting older. I used to be sick and physically not able to participate, but now I am riding with the guys—this makes me excited. I push myself physically, read up on and try out riding techniques. I ride with riders that are better than me. I watch and listen to the mechanics working on the bike. I freely admit to being a fan of Strava (a social networking ride tracking website) and love to see each of the improvements that come after working to become a better rider.

I dream of a better bike, but I know the one I have is still beyond my ability – but I research and gather opinions when I can. I have upgraded my bike computer so that I have up-to-the-second performance data to encourage me to be my best and not slack off. I have become a student of the road and can describe several different surface finishings for asphalt and concrete.

Every facet of riding brings with it a complete universe.

  1. I ride because riding is cardio exercise.

The American Heart Association says the maximum heart rate for a guy my age should be around 164 beats per minute. The highest I’ve ever recorded on the bike is 165 BPM. That measurement was taken somewhere in the middle of a ride and I pushed on for miles after and didn’t die, so, I assume there are a few more beats per minute left in me. But 165 is the best I’ve measured.

  1. I ride because riding is strength exercise.

Look at a really good rider.  They are lean, strong, and tough as nails.

That’s my goal.

  1. I ride because I get to wear bike shorts and shoes I can’t walk in.

Who can’t resist an old guy in bike shorts and shoes he can’t walk in?

How to replace a swage nut on a road bike to fix a water bottle cage or other accessories.

To get it out of the way; PEM®nuts and RIVNuts® seem to be swage nut trademarks so here are links to both companies: Penn Engineering & Manufacturing Corp. and Bollhoff Inc.

Better known as swage nuts or self-clinching nuts these are found in several places on the bike.  On my bike they are the nuts built into the frame for holding water bottle cages.

The thin aluminum frame around the swage nuts sometimes just can’t hold them in place and they get loose or corrode out.  Both happened on the bottom water bottle nuts on my frame.
