Garmin Edge 510 ANT+ Recording Stopped at Lap

Here’s something odd that happened during a long ride with my Garmin Edge 510 (firmware 2.90). While stopped in River Bends Park to climb over a tree I pressed the Lap button to mark the location so the tree could be removed, but then after that point the unit stopped recording data from either of the ANT+ sensors. Both the HR and Cadence values seemed to be stuck at whatever they were when the Lap button was pressed.

Firmware update 3.00 is out and I’ll try updating to that and see if it comes back, but as the change history simply states “Changes for manufacturing.” I wouldn’t be surprised if it happens again.

UPDATE: A bit of research has shown that it wasn’t actually when the lap button was pressed. It just happens to be right after that.

Here is the first record of the consistent/wrong 142 BPM, 24 RPM data:

<trkpt lat="42.64555980" lon="-83.04996448">
    <ele>160.6</ele>
    <time>2014-05-04T21:32:47Z</time>
    <extensions>
        <gpxdata:hr>142</gpxdata:hr>
        <gpxdata:cadence>24</gpxdata:cadence>
    </extensions>
</trkpt>

Here’s the lap marker, which shows it was earlier:

<gpxdata:lap xmlns="http://www.cluetrust.com/XML/GPXDATA/1/0">

    <startTime>2014-05-04T21:32:09Z</startTime>
</gpxdata:lap>

Close, but definitely earlier.

Carbon Fiber Shoes, Squishy Fork, Lubed Cassette

A rainy, quiet Saturday while Danielle is working gave me a nice opportunity to get some bike stuff done. In preparation for what I hope to be a long ride tomorrow and the Fun Promotions Stoney Creek 6 & 12 Hour Mountain Bike Endurance Race I removed the rigid fork from the El Mariachi Ti and put the original Fox and Arch EX-based wheel back on. While I like the high volume tire and rigid fork, it’s still a bit much for long rides. Thankfully the swap between forks and wheels is easy, taking only about 15 minutes. I imagine I’ll be switching this around a few times this year.

I also had to re-remedy a long-standing problem with the cassette on the El Mariachi Ti: it’s noisy. Last year I was dealing with some odd under-load ticking sounds that were worst mid-cassette and in the little chainring up front, especially when really mashing on the pedals. After a lot of experimentation I was eventually able to reproduce it and found it could be alleviated by lightly greasing the plastic spacers between the cogs. This seems to last for a few months, then it needs to be done again. This should go away once the cassette is replaced, unless the next one has a similar problem…

Finally, I got a pair of Specialized Pro MTB shoes set up and ready to use. At the end of last year I was able to pick them up on clearance at Cycletherapy, since they are the discontinued model with a strap closure, as reviewed here. These are very similar to the Comp model that I purchased in early 2011, except with more venting and a carbon fiber sole. Three years the Comp shoes were starting to get near the end of their usefulness, with holes appearing in the sides of the toes, the sole becoming more flexible than normal, and the insole seriously breaking down.

I appear to have the cleats positioned appropriately, although the pedal body on Eggbeaters seems to hit the lugs a bit. I’m not yet sure if this’ll cause a problem or is a good thing, but if it ends up not working I’ll have to shave a millimeter or two of rubber off of the lugs. Clipping in is a little stiffer than I’m accustomed to, but the solid shoe-against-pedal feeling makes for a very rigid interface. It should also move energy transfer to a larger area, cutting down on the pedal wing / shoe sole transfer that eats through Shoe Shields.

Trying the shoes out on the trainer and in the rain around the parking lot, they are definitely stiffer than the non-carbon fiber composite Comp shoes that I normally wear. They improve on the Comp shoes stiffness to the same degree that the Comp shoes (and my previous Sidis) improved on the Shimano SH-MT40 commuter shoes I’d first started out with. Fit is almost identical to the previous shoes, but with a new, stiff, less slipper-like feel. These should be good.

Ideas… Ideas…

Today is one of those days where I find myself with lots of ideas for things to do swirling around in my head. I just have to parse through them and figure out which ones are feasible, and when I can do them…

So, what am I thinking would be good to do? Here…

  • Take a half-day on Thursday and go ride Poto on a single speed before the Waterloo public meeting with the DNR.
  • Take a half-day on Friday to hike PLRA and gather more GIS data for mapping.
  • Order some wide, hookless carbon fiber rims from Light-Bicycle to build a new set for the El Mariachi Ti. Then sell the existing Arch EX wheels…
  • Hike River Bends and clean up any lingering deadfall. Maybe Saturday?
  • Attend the Stony Creek Trail Day.
  • Write up a new description for Massive Fallout.
  • Write up a document trying to convince more people involved in volunteering to work on MTB trail stuff.

Now, to find the time…

Defective REI Venturi Shorts (2014)

A few days back I picked up a pair of the REI Venturi shorts, as I needed more shorts and these were quite comfortable when tried on. I wore them for much of the day today and they were comfortable, but poorly engineered pockets is causing me to return them.

Upon arriving home from my parents’ Easter dinner, when reaching into my left pocket with my right hand to get my keys, I heard a tearing sound. It turns out that the thread used to stitch along the pockets is not as stretchy as the short material itself, and stretching the edge of the pocket causes the stitching to burst, as seen above. At $69.50/pair I expected better, and I’ll be returning these tomorrow. I’m disappointed in this because they are comfortable and met a need.

A Wish Fulfilled

Ever since beginning to do mountain bike trail work and seeing the effect of a heavy storm on trails I’d wanted to see this first hand. Today I saw this, and no longer wish to. JD Harvey and I were part-way through the more remote parts of some single track at Stony Creek when a hail storm arrived. Trees fell around us, an inch or two of 1-2cm hail fell in minutes, and we had to ride rough single track near-blinded to get out. This makes for a good story, but something that I do not wish to repeat.

Today’s weather was quite excellent, and after plans with Joy and Mark there was a bit of time, so I decided to go for a first-ride-of-the-season at Stony Creek on the El Mariachi Ti with the CroMoto Grande rigid fork. Not long after beginning the 6/12 Hour route I ran into JD riding his new fatbike, so he and I began riding together. After completing one lap we decided to start another, planning to part ways at the Swamp Cutout of the Roller Coaster so he could ride home to Rochester and me to the car. Not long after starting it seemed to be getting dark quickly, but we pressed on as we normally would have been out of the trails within fifteen minutes. Just before reaching the end of the Saturday/Sunday Reroute, within the span of 30 seconds a bit of rain spat, then the wind kicked up and hail began.

Unlike my usual experiences with hail and thunderstorms — where it lasts for a few moments before changing to torrential rain — this didn’t let up.

As we made our way to the climb to the Rest Area I called for us to stop and walk up the hill to save time, something which seemed to be over in a flash. Descending from the Rest Area to the Swamp Cutout was a haze as riding instinct took over. Whenever I’d look up from the trail I’d see branches and whole trees falling in what appeared to be a fog of painful ice. I fell briefly when rounding a small drop/corner (same places as here, five years earlier) due to my wheels rolling out from under me on the ball bearing-like ice, but save for interrupting our escape this was uneventful. Once getting down to the Swamp Cutout we found that the entire forest was covered in 1-2″ deep balls of quickly melting hail.

The usual route back to the parking lot, straight from marker 29 to 2 was blocked with an immense tree, so we turned back, detoured along the single track by marker 3. Between that point and the parking lot we had to climb over at least three more trees, and make a last-minute duck to avoid the neck-height wire which had fallen across the trail. I’m very fortunate this wasn’t a live power line, as I saw it just in time to duck, glancing my helmet off of it.

Once back at the car I quickly packed my bike inside, put JD’s on the rack, then got us both in the car with the heat turned on high. The photo above (and this one) were taken near the exit of the West Branch parking, as the hail began to melt. The river-like washes through the hail were exactly that: places where water was flowing down the pavement channeled through the ice. While packing the car this was flowing over my feet, something which I paid no mind as I was just happy to be out of the woods.

While this was quite an adventure, the worst storm I’ve been caught in, a good experience, a fulfilled wish, and something for good stories, I do not want to repeat it. We both were very fortunate that we didn’t get caught up in any of the falling trees, didn’t crash in a serious way, nor encounter any other catastrophe. Simply having wet/dirty bikes, some welts (I’ve got a large one on each forearm and a sore finger), and a story to tell show just how fortunate nature was with us. This shouldn’t be pushed a second time.

High Volume Tire for Rigid Fork

 

With Dually rims acquired I started looking around for parts to build up a high volume front wheel for the El Mariachi Ti when it is sporting its new rigid fork. Within a few days of poking around on eBay I had everything needed, some nice spokes, a Shimano XT hub (same as on the OE El Mariachi Ti wheels), and some generic (but nice) blue nipples.

On Wednesday evening I laced the wheel, and thinking everything had gone great I tensioned it on Thursday night, finding myself very happy with how it came out. Tension was very even, it was true to within 0.5mm, and dished to less than that. All was good until I started looking it over and found that I’d made a very amateurish mistake, something I haven’t done on any of the other wheels I’ve built: I put the valve stem hole in the wrong spot: photo.

If I’d made this mistake on a normal rim I could have easily shuffled the spokes one hole over and all would be good. Not so on the Dually with its offset drilling. This required me to completely unlace and rebuild the wheel to get it right. This morning I found myself awake particularly early (a combination of Danielle’s alarm and my consuming too much caffeine the day before), so I headed down to the basement and relaced the wheel before going to work.

This evening I tensioned it, fit the tire, and set it up as tubeless. During tubeless setup I was a bit concerned that I didn’t have tape wide enough to cover the spoke holes, but as this photo shows, Velocity’s 24mm Velotape is more than wide enough to cover the spoke holes. All went good, and now I’m looking forward to dry trails so I can try the wheel. I may also try it in the suspension fork, as it fits very nicely: photo.

The assembled wheel came out to be 1821g with tire and lockring, but without rotor. This is heavy, but it was expected, as the Dually is 215g heavier than the Arch EX normally used on the front of the bike. Being rotating weight this is likely to be noticeable, even with the ~400g saving of the rigid fork. Measuring 63mm wide (7mm more than the 2.25″ tire on the Arch EX) I’m expecting the extra volume to make it worthwhile. If not, it was a fun experiment and the wheel can likely be sold for what I’ve put into it. Total cost was $137.16, not counting the tire which I’ve had sitting on the shelf since late 2012. (I believe the tire was around $40 via Chainlove.)

Here’s the build specifics:

Rim:  Velocity Dually 29″ (45mm wide)

Tire: Schwalbe Racing Ralph 2.4″ (Old Tread Pattern, Tubeless Ready)

Spokes: Ritchey-branded DT Swiss Competition 2.0 (296mm)

Nipples: Generic Blue-anodized Aluminum

Hub: Shimano HB-M788 (15mm TA, Centerlock)

Rim Tape: Velocity Velotape (24mm wide)

Valve Stem: Stan’s NoTubes 35mm

Spoke Tension: ~120 kgF on the higher side.

2006 Honda Civic EX Valve Cover Gasket Replacement

Some time in mid-2013 I noticed that my car’s engine was getting a bit oily, with all of it appearing from just below the valve cover. This meant was time for a new valve cover gasket. While I’m not much of a car guy, I figured this should be a relatively easy DIY repair, and it was. By following both Chilton directions (thanks, MeL!) and some of this YouTube Video I had no issue with this repair. Following a test drive last night and today’s trip to work no new oil is visible on the engine, and it seems to be running properly. Out of pocket cost was $31.25 (for the gasket set and some RTV silicone), and I suspect I saved $100 – $200 in labor costs while learning something.

With new tires fitted yesterday, there’s only one active issue left with my car: a rattling/resonating when load is applied to a cold engine when the RPMs are low. I suspect it’s a tensioner or pump that’s sticking a bit. Hopefully within the next couple of days I’ll get some time to diagnose this one as well.

Velocity Dually and 2.4″ Schwalbe Racing Ralph

Velocity was at yesterday’s Detroit Bike City expo selling blemish / second rims, and I was lucky enough to pick up a pair of Dually 29″ rims for $60; an incredibly good price. While I’d previously discounted the idea of making a special / wide front rim for the rigid fork of the El Mariachi Ti, with the acquisition of this rim I think I will.

By fitting one of the new 2.4″ Schwalbe Racing Ralphs (old tread pattern) that I’ve had sitting around home I found what should be a great setup for the rigid fork. Set up tubeless it should feel especially nice. Hub-wise I think I’ll go with the same Shimano HB-M788 that I use with the original wheel build, some Sapiem or DT Swiss (depending on what I can find) spokes, and either silver brass or blue alloy (to match the rear wheel) nipples.

After fitting the tire for the test fit I let it sit for a while and measured it. For the Dually with a Racing Ralph 2.4″ it measured at 61.32mm, whereas the original Arch EX and Racing Ralph 2.25″ measures at 55.77mm. The Salsa Semi and Racing Ralph 2.4″ on the steel El Mariachi measures 58.47mm. Thus, this wider rim doesn’t seem to notably increase the width of the tire, but hopefully the additional volume will offer just the right amount of cushion to go with the rigid fork.

And hopefully I can do it on the cheap.

172.5mm Cranks and a Third Bottle Cage

This evening I fitted the Salsa Vaya with some eBay-special 172.5mm cranks. These are the same model (Apex) as came on the bike, but 2.5mm longer, which I hope will make me more comfortable on the bike. I also fitted a third bottle cage, which I hope to use this weekend. I’ve been invited to a century ride on Hines Drive, a popular road riding location on the west side of Detroit. If all goes as I hope — which includes weather cooperating — I intend to use this bike to do a wholly self supported road century on Sunday.

A Project Unfinished

Thirteen years ago, back when I moved into my apartment, I started building what was to be a solid oak mission style queen size bed. I got a fair ways into the project, finishing the posts and horizontal pieces for the head and foot boards, but I never went any further because mid-way through the project I bought the condo where Danielle and I now live. Most of my time was directed into fixing the place up, and then after that I found different hobbies; from beer brewing to electronics, traveling to cycling.

Finishing this bed is one of those projects I’ve kept meaning to do, but at this point Danielle and I are looking to purchase a king size mattress, which wouldn’t fit into this bed, rendering it somewhat useless. This is something I never got around to finishing, and found myself at the point where it was time to abandon it.

Last week I offered the wood to my dad as a project that he could finish up and today he picked it up. I’m really glad to that he wants to work on it, and thus I hope it’ll serve as an enjoyable project and end up as something my parents can use.
