Bryce Canyon National Park

Once I got to Bryce I found out something really cool about the park which helped me out a lot. Apparently the park is too overpopulated during the summer months, so the park runs a shuttle bus along all the tourist points in the park. This gave me a break and saved some time and effort.

The major attraction at Bryce is the hoodoos which are tall rock spires. Basically it is part of the side of a plateau that has eroded strangely, not really a canyon at all.

I decided to use the shuttle bus a bit, but also take advantage of not having the bike to go hiking along the rim trail to see a bit more of the park. I have to say there is an amazing variety to the people in the parks. Most of them don't seem to be very much the outdoor type, but instead just the general tourist. There are a huge number of foreigners as well, some with large tour groups and others not. Most people also have gigantic cameras, many of whom probably also don't know how to even take it off of the auto setting.

More bad news

I woke up this morning to another flat tire, on the rear wheel. Apparently I missed a thorn, which had worked it's way further into the tire after I changed it last night, so I changed my third flat tire in the morning.

After that it was relatively uneventful until I got to the Capitol Reef area. Then the wind started to really pick up a lot, and of course it was a headwind. I saw some cool petroglyphs on the way in, and then went most of the way down the scenic drive in the park, until I was going up a steep road into a strong headwind, and didn't think I would see much of anything different I kept going. The way back was much nicer with the downhill and the tailwind.

That was until I got back to the campground area, where my rear tire blew out completely. I pushed my bike into the camping area and started to change the tire again, when I realized that the actual tire had worn through, and not just a popped tube.

I sat there for a bit trying to figure out my options until the camp hosts stopped by. I asked them about the area, and they didn't think there was anything close but offered to call the rangers. A bit later a ranger stopped by and told me he was going to call a place in the nearby town, about ten miles away. He took the info about the tire and rim and then left. A while later he came back and told me the store did have a suitable tire but that they would close in ten minutes. He offered to drive me and my bike there, so I threw everything in the back of his truck and he drove me into town. We arrived around 4:05 and the store was supposed to close at 4:00. Fortunately the owner hadn't arrived yet to lock up, so I was able to buy the new tire. It's a bit wider than the one I had, and more of a mountain bike tread, but it fits just fine. For $27 I was able to get back on the road and didn't even have to hitch a ride or take any extra time to get things up and running again.

Flats

I posted my last update from a picnic table in Hanksville UT where I was sitting with three other bikers who were headed east. I had already done fifty miles to get there and was planning on taking a break in the shade anyways so it worked out nicely. I know I made a post about how I hadn't had any flats yet, an it seems like I jinxed myself.

After taking care of everything in town I left, planning on spending several hours in the shade of a bridge by a river. I managed to get down to he water ok, and spent several hours relaxing in the shade. I realized that I had pushed my bike through some prickers to get there, since I was pulling them off of my socks, but didn't really think much of it. After I was done with my break I pushed my bike back u to the road, where I realized that both my tires were flat. Since I had been with my bike the entire time I knew it was punctures and not just someone letting the air out.

Replacing both tubes was interesting, since I was sitting on the side of the road with my bike completely in pieces. I started fixing one flat with a patch kit, when I decided to just use the two new inner tubes I had bought, and I would fix he flats later in camp. When I was part way through that I realized that the valves on the new tubes were different, being presta instead of schrader. I wasn't sure if my pump would work with these, but I knew some pumps were interchangeable. It took some work on the pump, and I had to take apart the pump head an reconfigure it, but eventually I got the two new tubes on, got the tires on the bike, and got them both inflated with air. Now I'm just hoping that the sharp points I felt on the inside of the tires were the only ones, and that I was able to fully remove the sharp bits. Otherwise I'll end up with more flats tomorrow morning.

Noise

Over the past 1000 miles my bike has been making more and more noise, mainly due to the chain. Each time I stop I mean to pick up some chain oil, but I have been forgetting each time. Yesterday when I was in Green River, UT, I met Ben, another long distance cyclist, in the town park. We talked for a while, and hung out a bit. Before I left I remembered to ask him if he had any oil I could use. Fortunately he did, so I applied a bit to each link in my chain before returning it.

Today as I was riding along I realized that my bike was making almost no noise, which was really strange. It was nice and calm, and there was very little traffic, so it seemed like I was just flying along. Now I really have to remember to pick up some chain oil next time I get a chance, since it is really nice to not listen to a chain rattle. I also think it runs smoother, since it seemed like it took a lot less effort to pedal today. That might have just been due to the lack of major hills all day, but it was still a nice change for once.

Repairs

On the way from Monticello to Moab my bike started making strange noises so once I got to Moab I wanted to have it checked out. I went to the first bike store I came to, which was Moab cyclery, and described the noise and what actions cause it. Basically every time my right pedal neared the top of it's rotation there was a creak that didn't use to happen.

After I described it to the mechanic he was able to tell right away that the bottom bracket was either loose or dirty. He proposed to take it apart, clean it and then re-oil everything. After about 25 minutes he had it back together and had me try it out. Fortunately that fixed the problem, so I am back in business, at the cost of $15. At some point in the near future I would like to re-oil the chain and everything, but it can hold off for a bit.

After my previous research I have also been looking for different gears for the bike to give me a better ratio, mainly for climbing all the hills. I checked every shop in Moab, but none if them had any smaller gears for a five bolt setup like I have in front. Ideally I would like to replace the 30t gear I have right now with a 24t gear. This would help out quite a bit, dropping the slowest gear down to an ideal 6 mph, instead of the 7.8 mph ratio I have now. I might also replace the rear cassette with something bigger, which would also help the situation. That change is a bit more involved, likely involving a change in rear derailler as well.

Proper gearing

I did a bit of research to find out more about proper shifting technique for long distance biking. It turns out that it is more efficient to rotate your feet at a higher rpm with lower gearing. The ideal rpm is roughly 80-85, which is much faster than most people would be pedaling.

I also counted my gearing on the front and back gears to see what that might translate into for mph.

On the front gear I have 3 gears, with 30, 42, and 52 teeth respectively.
On the rear gear I have 8 gears, with 12, 13, 15, 17, 19, 21, 23, and 25 teeth respectively.

Given the tire sizing, one complete tire rotation is roughly 86.35 inches traveled.

Putting this all together I can figure out the ideal mph for each gearing ratio, as follows:

52 teeth 42 teeth 30 teeth
12 teeth 28.34 22.89 16.35
13 teeth 16.16 21.26 15
15 teeth 22.7 18.31 13.08
17 teeth 20.01 16.16 11.51
19 teeth 17.9 14.45 10.33
21 teeth 16.22 13.08 9.35
23 teeth 14.78 11.97 8.5
25 teeth 13.6 10.99 7.85

This has a few interesting features. First, I should be pedaling a lot faster, instead of harder. Second, I had always assumed that the middle front gear was always a higher ratio than the smaller gear. It turns out that some of the ratios with the smaller gear in the front can actually be higher, so it is not always a low, medium, high gearing in terms of speed.

I can use this information with my bike computer to determine which gearing I should be using, in an ideal situation. I have previously just been going based on changing gears whenever it felt too easy or hard to pedal. I'll have to see how this actually goes though, but now I have some data to use.

Lizardhead cyclery

As I passes through Dolores CO I saw a sign for a new bike shop that had just opened. I didn't really need anything but I decided to stop by anyway. They didn't have a whole lot of inventory yet, but they did have a lot of scrap parts. Most of these parts get turned into artwork in some form, which looks kind of cool.

One thing I did realize that I needed was some type of spacer to rotate my rear rack back a bit. The way it has been the pockets sometimes get in the way of my heels, and the rack isn't level. They didn't have anything but the owner scrounged around for scrap metal and ended up cutting apart an old gear to make two extenders. His solution also looks pretty cool, somewhere between steampunk and punk rocker. He also only charged me for the metal he cut up, unlike most bike stores that charge an arm and a leg for labor. It probably helped that the metal wasn't useable, so he was able to get rid of scraps and help me out.

More equipment

I decided I needed to get front panniers for my bike. It has been a bit of a pain to tie my backpack on top of the rear panniers, so I have been checking in all of the bike shops along the way to see what they have in store. Pretty much all of the shops have been mountain biking shops, so they don't carry the front racks or panniers. I did finally hit one in Montrose that had a front rack for $40, so I got that just to have something. Then I am having more panniers shipped to Dolores, CO, so I will get a bit more room in a couple of days.

First Week of Biking

I've been on my trip for about a week now. I ended up getting into the bus station in Ft. Collins around 2:30am, and walked about 4 miles towards an REI, where I was planning on buying a Surly Long Haul Trucker. While I was waiting for REI to open I found a bike store just behind the REI, where I stopped in to see what they had. Andy, one of the guys at Re-cycle Cycle, convinced me into getting a Raleigh Road Three Hundred. It isn't quite as nice as the Long Haul Trucker, but it was roughly $800 cheaper, and will still work for me. I spent roughly $450 on the bike, plus another $400 on accessories, including a bike rack and panniers, before heading out.

I spent the first day riding around town getting used to the bike and making sure everything worked, then headed out the next day towards Estes Park. The entire way was uphill, heading into the Rockies from the plains, and it was quite a long ride. The views along the way were worth it though, and when I get a chance I'll be uploading a lot of pictures, most of which are already geotagged.

The next couple of days included a lot of hills, and I'm definitely not used to biking yet. There have been a couple of nice small mountain villages, and most of the drivers along the way have been decent. The only real problem I have had along the way was in Black Hawk, CO where there is a bike ban. They apparently are more than happy to ticket riders, even though the federal law states that places can't ban bikes without providing a nearby alternative route, which they don't have. That case is currently being debated in court, so we'll see how things turn out.

New Camera

In 2011 while hiking on the Florida Trail my camera broke. I was using a Canon A480, which I had also used on my Appalachian Trail hike.

I was hiking in Ocala National Forest, and wanted to take a picture of a pond and sunset. When I was pulling the camera out of the case, I hit the on button, and the lens tried to open while in the case, which broke something. The camera was still usable, as long as I pushed the lens in by hand each time. I've been using it for the past year like this, but on the recent hike of the Florida Trail, a bunch of sand got in the lens, causing dark spots on the pictures. I finally decided to upgrade.

My new camera is the just released Canon SX260HS. I have been eyeballing the SX230HS for a while now, and this is just an even better version. The main useful features are the built in GPS, 20x optical zoom, and 12 megapixels. No really exciting pictures yet, but I've been trying the camera out around the house, and I'm definitely liking it. The GPS is going to be really useful for documenting future trips.
