I guess it's official, Giant has no idea how to build wheels.

This is on my Giant Seek 0, which I like pretty well otherwise.

270 miles, 2nd broken spoke. I don't know how long ago it broke, I was just doing my pre-work week mechanical check and found it.

(viewing from the drive side, proceeding clockwise from the valve)
The first broken spoke was #12
The second broken spoke is #8
both drive side, of course. Not a big deal with an IGH, there's just a plastic ring that snaps off to get spokes in and out.

My previous Giant bike broke 12 spokes in about 1200 miles, at which point I gave up and bought a double walled rim and some butted Wheelsmith spokes and built my own rear wheel. That was my first ever wheel build and it ran for 15,000 miles without even going out of true a millimeter.

Given this experience, when the first spoke broke on the new Giant, I just bought a whole 50 pack assuming that I was going to need them.

The water sticking to the ground this evening is already somewhat crunchy and the forecast is for 28*F by morning, so the studded tires went on the new bike this evening.

And in the process, I found that there's already a broken spoke, at 163 miles. That's poor even for a crap bike, I expected more from a $1100 bike. I guess I'll retension the spokes after I replace that one. I may have trouble finding a replacement locally, it's a 266mm spoke, quite short due to the IG hub. So I went on Amazon and ordered a 50 pack of black Wheelsmith spokes from AE Bike, since I bet I'm going to break more of them.

Today's (*) flat tire actually had a reason (all previous flats on this bike have been due to snakebite - which I've pretty much eliminated by keeping the tires well inflated and changing my riding style to less in the gutter so I'm not hitting rough bits as much).

Looks a bit like a steel wire from a wire brush or something. Does not look like a wire from a tire band.

(*) this was from September 4. I changed the post date but this is not reflected in the post for some reason.

Had a flat tire (rear), was a bad patch - one of the old square ones done with bad technique. Replaced patch. Rear tire center is clearly worn flat but still lots of miles (it has 1000 miles on it now).

Reconfigured - moved handlebar bag to seat post on a ToPeak T bar to free up bar space for headlight in a normal position.

Chain cleaned and re-lubed with Chain-L lube (new lube). VERY quiet running, supposed to be an excellent lube. Really thick. Chain still does not register as even 0.75 wear on the chain gauge.

I got to work with a flat tire Friday morning. Could not find a leak. Dropped in a new tube. When I got home, I submersed the tube and found that the patch I put in last night was a bad job with a tiny little leak. Removed it and reapplied more carefully. In the future I will test the patches before reusing the tube.

My new road bike came with Michelin Dynamic Sport tires. Clearly they use these because they're the cheapest things they can get; they're basically just a paper thin skin over the tube. Fair enough, since everyone has their own favorite tire, there's no point in putting $80 tires on a new bike. I decided to see how long they would last.

Today the rear died. I was highly suspicious of it yesterday and intended to swap it out but I got involved with a car repair. Today on the way home I braked hard at one point, scuffed the rear, and within a mile I was getting "thump thump thump" - the tire had begun to bulge where the scuff happened. I let some air out of the tire and the bump bump bump mostly went away and I made it about 6 more miles, but then about a mile short of home due to the lower pressure I got a snake bite flat. I just walked it home from there.

So FWIW, a Michelin Dynamic Sport 700cX23 inflated to 110 PSI carrying a 180 pound dude lasts about 830 miles on the rear. The one on the front is barely worn. I swapped it out and put on two new tires anyway, I'll keep the front Michelin as a spare. The new ones are Nashbar Prima 2s made by Cheng Shin. They're on sale for about $12 right now, I should probably grab a couple more.

First flat on the new bike today. I hit a pothole and got a pinch flat. Observations:

  • I put my headlight on the helmet. That's a lousy place for a light, it gives you no contrast to see potholes. The handlebar bag is in the way for lighting, but I'm going to have to figure out something else - perhaps on the bars under the brakes or something. I have to get the headlight down lower.

  • The skinnier tires are actually a little easier to change than the 32 to 35s that I run on the other bike. Or maybe it's just these particular tires. I have some Nashbar Prima 2 tires coming - they're $15 and the reviews say they are long-lasting (4000/8000 miles on front/back) and pretty puncture-resistant.  The tires this thing came with are said to only last 2000 miles or so, so I'll be wearing them out this summer.

  • I flatted in a lovely spot for changing a tire - 5 foot wide paved shoulder, good lane markings, a proper curb and a nice sloping mowed grass verge. I've had to change tires on a rutted loose gravel spot with a dropoff into the ditch and no shoulder before.

  •  I hope I don't flat again before I get home - I only have one spare tube and no patch kit. I suppose I should toss a patch or two and some cement into the kit. (I hate glueless patches - they don't work well for me and I just have to scrape them off before putting on a REAL patch).

Should have put them on last night, but the forecast didn't look quite that bad and I didn't get home from the concert until 9:15 or so.

The Bontrager Race Lite 32 that I had on the back is showing cord through the rubber. I have no idea how many miles it has on it. It was on the front when I bought the pair. When the rear went, I replaced them both with Marathons and hung the one in the front up. When the rear Marathon died I put the Race Lite on the back. I really have given up on keeping track of mileage on tires but it has been quite a few miles on this tire, probably something like 10K all told.

The Marathon that was on the front is now on the back. I expect it to last until fall of 2013. The front now has a new Pacela Panaracer 32 that I bought on clearance for $12 about 3 years ago and has been in the basement.

Wow, eBay to the rescue. I picked up the three broken bits for the front end of the Malibu for about $100. Locally just one of them was $200 and the three together would have probably pushed > $350. Total time for the fix should be about 3 hours.

Not replacing the hood right now, because I can't put a new one in the winter weather in primer or it'll rust, and I can't really paint a hood in the current weather either, too cold. The existing hood isn't too bad after some jumping up and down and punching (literally). I'll probably replace the front bumper cover at the same time.

I still need to straighten out the hood latch, it's shoved back almost into the radiator.

I put my new Nokian W240s on the bike today, it was time to give in to the inevitable. On a quick trip down the driveway, wow, are those things noisy. Very aggressive studs. I'll see how they roll tomorrow.

The surviving Top Touring 2000 that Eric gave me a couple of years ago started acting wonky last week; the handling got really squirrelly feeling, like it was squirming, and I started to feel bumps when I was on smooth road. I didn't see anything on the first inspection, but when I looked again a couple of days later I found that there was some very slight sidewall bulging and some weathering. I suspect it has separated tread inside given how it was giving me a weird feeling while rolling.

Not wanting to have a tire blow out at 30 MPH, I pulled it off and trashed it today and put on the old Bontrager Race Lite from a few years ago. That should hold me until the studs go on next month. I also have a brand new Pacela tire in the basement for next year. I think the front tire is a Marathon. I'll probably put that on the back next spring and the Pacela on the front.

I don't really want to say that I'm actually looking forward to putting studded tires on, but I'm curious to see how the new Nokian W240s ride.

  1. I now have a bike tube with 7 patches on it. One of those is actually 3 patches, the 2nd two covering a big crack in the first. The other tube is a brand new one after the last one got too bad to mess with anymore.
  2. twice now I've had the name brand patches crack and cause a new leak. The cheap-assed 30 for $3 patches I got from Harbor Freight have yet to fail.

That flat tire took out the tube irreparably (rode a few feet too long on it, there are a dozen tiny holes). I had a brand-new spare in the garage, but it had dry-rotted. I guess in the future I'll keep my spare rubber in the basement, the garage gets very hot and very cold and probably has petroleum fumes and such, and I've had tubes rot there in the past. I should probably move my tires out of there as well.

Went to Meijers this morning, but they have nothing but those horrible "self-sealing" inner tubes. That's code for "won't actually self seal, but it'll spray gunk all over and make it impossible to patch. And we'll charge you double. Forget it, the bike shop will be open this afternoon.

They also stock nothing but 27" tubes. Now, 27" tubes will work in 700c tires, but they're not optimum. As far as I know, nobody has made 27" bikes for a decade. Maybe some of the department store crap bikes are 27", I don't know. It does lean me even more towards thinking that if I ever buy a touring bike it'll have 26" tires. You can ALWAYS buy 26" tires and tubes, at any department store and in any country in the world.

My tomato plants weren't terribly happy this year. I'm nursing some Big Boys and I think one Early girl and I think they'll make it and take off soon, but the Cherry that I put in the ground a few days ago died; I probably injured the roots. Next year I'm going to use rolled newspaper pots for everything. The cukes I started like that are happy.

...but Meijers doesn't open their garden section until some late hour like 8AM or something, so I went across the street to Lowes. It's too bad I didn't need Big Boy tomatoes or one of the ridiculously-sized tomato plants, because they have literally hundreds of those. They had ONE SPOT for cherry tomatoes, which means maybe 16 plants (2 flats) and of course they were gone.

So I grabbed one grape tomato plant. What the heck, I've got a couple of empty spots. Maybe we'll find a cherry tomato plant somewhere else.

Next year I'm going to put some work into a more proper seed starting system. I really need to have a cold frame, and perhaps a heated base for sprouting, they seem to be pushing that stuff. Just getting them up out of the basement and into actual sunlight would probably help a lot.

I don't get a lot of flats, but it does happen. This drywall screw made a hell of a racket when I picked it up, whacking against the fender stays. This was about 300 feet from the driveway into work so I only had about 1/4 mile to walk. It's a lot more comfortable dropping a new tube in at work than on the side of the road, and probably faster too; I was done and pumped back up again in about 6 minutes.

As an aside, I had a flat on, um, Thursday I think, slow leak. Patched it Friday morning, found that the Schwalbe Marathon that was on there was paper thin down the middle, so I tossed on the remaining Top Touring 2000 that E.O. gave me a couple of years ago (one of them self-destructed). It's doing well but it feels like it's filled with concrete in comparison to the Marathon. I think it's actually skinnier even though they're both theoretically 32s.

I didn't find what caused the flat, since I rode on it for at least 6 miles after noticing that it was going flat, it probably just came out. But since I'm not using that tire anyway, I guess it doesn't matter.

New studded tires arrived today, for use this coming winter. These have everything I think I want in a winter tire. They're knobby enough to grip in snow, yet have a fairly unbroken center line so they will still roll smoothly on pavement. They have studs down the center to grip on ice and down the sides to climb out of ruts.

Studded tires taken off the bike (perhaps a bit optimistic, but last year I took them off on March 7 and got away with it). Very little riding this winter, only 273 miles put on these tires this winter.

Got the power washer and a hose out and washed it for the first time in a few months, but since it'll still freeze, I had to blow the water back out of the washer.

Then I figured out why the tool kit has tried to fall out of the bottle cage a few times lately; broken weld. I replaced it with a spare cage I had sitting around, though it's a cheap piece of junk, it'll last a while.

The bike's rear tire was not quite totally flat but extremely soft this morning. Pumped up the tube, didn't find anything on a 15 second exam, wanted to get to work, so I just threw in another tube.

Found the leak this evening by water immersion - it was so slow that it wasn't immediately apparent even then. Pinch flat (snakebite). 2nd one I've gotten in the last few years. Not too surprising, since I let my pressure get down pretty low, perhaps as low as in the 30-40 PSI range, and the gravel road I ride on is getting relatively miserable - really bad washboarding. It may be about time to take another route for a while. The next shortest route is another 3 miles but only an extra 7 or 8 minutes since it's all relatively flat, decent paved roads, and it's still fairly low traffic.

Gotta remember to keep the tire pressure up.

Had a soft tire last night, started to change it but it was only soft, figured I could pump it up and see how far I could get; at least I could get to a road that wasn't busy with 60 MPH traffic. Made it home, but it was dead flat this morning.

Found a small puncture. Did not find the cause. Installed the spare, the punctured tube is at home awaiting patching, the alternate spare I put in the bag I'm not too sure of, it might be dry rotted. I didn't test it, as I don't have any more spares anyway. I'll test it tonight after I get the other tube patched.

This is my first flat with the Marathon tires. Rear tire, FWIW. It MAY have been a pinch flat, I didn't look at the tube closely. I'll check it better tonight.

I just cut up another tube that was dry rotted along the folds, to use as straps to tie up a tree that needs straightening, heavy duty rubber bands and other utilitarian uses.

Odometer: pretty close to 21000 miles.

I have one good Nokian studded tire (the other has a number of studs ripped out or pushed through the tire), and they do much better in deep snow than the Marathon Winters, so I put it on the back of the bike tonight. The Marathons do OK on the front, but on the back, which has most of the weight, when under power (downstroke) the rear tends to sideslip when on a few inches of wet, greasy snow.

So, the Marathon Winter that was on the back last year is off, the Nokian that used to be on the front a couple of years ago is on the back now.
