After all the riding around near my grandparents house and at Stony Creek a bunch of times this last week my bike had become pretty dirty. The area inside the rim around the spokes looked particularly bad. While it really wasn’t that bad compared to some I’ve seen photos of, the built up crap in the cassette and wheels and down tube (and everywhere else, it seems) had me wanting to wash it. So, I did. A bunch of time was spent with car wash soap in a bucket, brushes, some diluted degreaser, and a few rags to get the bike nicely clean. After concentrating on the frame and various other bits I gave the drivetrain itself a detailed cleaning.

After the rear cassette was shining brightly and the chain properly oiled I took the rear brake caliper bolts out one at a time and applied some Loctite Blue to hopefully hold them more solidly. I’d rather not have the problem I had last time, or the inverse, where my rear brakes would have simply stopped functioning. (Because of how the front calipers bolt on, this can’t really happen there.)

The rear frame was then put back on, and I was actually able to identify the source of the extra noise while riding over bumps. It seems that it wasn’t the bag / rack, but instead the place I had chosen to put my pump was rattling against the rack itself and had even worn a small hole in my bag. I repositioned the pump into the middle of the bag and wrapped the extra tools in two rags to both take up space and give me useful rags. A test ride around the neighborhood up and down some curbs (and managing to slightly bunny hop a few times) I didn’t hear anything more than chain slap, so I guess things must be better. (I do need to build a chainstay guard to eliminate this, but that can come later.)

If things go as planned, tomorrow and I will be heading out to Stony Creek for some nice riding, and Wednesday evening I’ll be participating in a regularly scheduled group ride in the same area.

On Saturday afternoon I took advantage of the unexpected lack of rain and headed out to Stony Creek to ride on the trails a bit more. While coming up over one of the hills I noticed a guy standing at the top of one of the hills taking some pictures. Later on, back near one of the high points on The Rollercoaster I saw him stopped, so I stopped to ask him about the pictures.

He’d said that he had been taking some, noted my email address, and said that he’d email me the photo. Later Saturday night I received the image above attached to a message from Eugene Mazur. It’s kinda neat to see a photo of yourself in motion, in context.

From what he said, Eugene is fairly new to mountain biking as well, so I mentioned the Wednesday Night Stony Ride which I’d recently been made aware of. Maybe he’ll head out there. It sounds like it would be fun to meet up with some people and ride around on the trails, so I’m going to try and make it this week. I’m also hoping to get out to the park and ride on Tuesday and Thursday with , so this could be a nice week of bike riding. I think tonight I’m going to wash my bike and give the drivetrain a good cleaning, because things are pretty dirty from the weekend of riding up at my grandparents house in very sandy soil and the few days out at Stony over the last week.

Just after starting to descend The Rollercoaster at Stony Creek (a windy, narrow, fun descent from the highest point in Macomb County) I applied my rear brake and started to hear a tremendous houl from my rear brake and found myself slowing very quickly. I was able to finish stopping with my front brake, just as someone behind me asked if I was all right, and what the sound was.

A quick check showed that the upper bolt on the bracket which connects the caliper to the frame itself had come off and that in squeezing the rotor the caliper had rotated forward and lodged itself against the disk, slightly stuck between the frame and the disc. Walking about 15′ back up the trail I found the screw, I was able to partially put it back in by hand. Because of the length of the tool I couldn’t fit it between the rear rack and screw head, but thankfully the person who had stopped had a much shorter wrench and I was able to tighten things back up. A quick readjustment of the brake and I was on my way, with the brake actually working better than it had previously.

I’m not really sure how the screw came out. It was tight the last time I checked it (a few weeks ago), and it had thread locking compound on it. I do wonder if the combination of the rear frame, the slightly ratting bag, and the rough trails contributed to the bolt loosening.

Today I headed back out to Stony Creek with the frame removed and with only a multi-tool and my keys. While I didn’t like riding without the ability to fix a flat, I accepted the risk of a five mile walk until I can sort out the CamelBak Question. Things went well, and it seemed like it was a generally a quicker ride with the lighter bike, except it seemed like I had a much harder time getting up some of the steeper / longer hills (generally in the two-track area) because I kept spinning the rear tire. Twice I just stopped part-way up and walked. It was a much quieter / pleasant ride, although I do think I’ll get (or fashion) a soft chainstay guard to cut down on the loud chainslap.

Now it’s time to shower, eat something, and poke a bit with Ivan’s P3. I received new firmware, but it still doesn’t seem to be working, so I’m going to write a little test software for the PICs and be sure they are working right.

To those of you who ride bikes and read this, I have a question about CamelBak bags.

See, I have a frame for the rear of my bike, and with its bag it’s great for touring type riding, but it has a couple deficiencies:

· It rattles a LOT on even small bumps.
· While it holds the normal bike stuff I’d want to bring (multitool, spare tube, pump, keys, wallet, cell phone, tire levers, Clif bar) it doesn’t hold my camera very well.

Yesterday I swung by REI and picked up an Aero Wedge Pack (Medium) for $26. It was really easy to fit to my bike, but with it I have nowhere to put my pump. I can fit a tube or patch kit, but not any method for reinflating things.

I’ve been hesitant to get a CamelBak because of the price, and because when outside in warm weather while wearing a backpack my back tends to get really, uncomfortably sweaty, to the point where it makes me hot a lot quicker than normal.

I’m just not sure what to do, and I’d love suggestions. I could keep the small Topeak bag, and carry a patch kit and CO2 inflator in it instead of a spare tube. The on-bike water (about 1.5L) is sufficient for most rides I’ve been on so far. I could return to Topeak bag and get a CamelBak and use it instead of the rear rack / bag full time, or at least until I need the rear stuff. Or I could deal with the really loud / bothersome rattling and lack of space.

If you would recommend a CamelBak for me, which model? The M.U.L.E. seems to be the most popular, but it’s also REALLY big. I don’t know if it’d be overkill. It’s $86 and REI, and returning the bag I purchased yesterday would offset $26 of that.

Something I’ll post about later, probably with a photo: While riding The Rollercoaster at Stony Creek yesterday my rear brake suddenly seize, accompanied by a loud howling sound. What had happened? Somehow the upper bolt on the rear disc brake mount had come out, causing the brake to pivot forward and the upper edge of the caliper to stop the bike as it ground against the edge of the disc.

I actually found the bolt a little ways back down the path, and it wasn’t too difficult to get it back in and get the brake readjusted. I did run into the problem the rear rack being in the way of the bolt, and my multitool wouldn’t fit in there. Thankfully someone who had stopped had a shorter one and I was able to tighten things up with that. What’s strange, though, is that this bolt was tight not too long ago, and it was Loctited.

Today after work I rode to Rochester, then a little ways down the Paint Creek Trail, then back to work. It was a total of just over 16 miles, but they were particularly tiring. I also learned a bunch of things during the ride, and here are some of them:

· Auburn Hills and Rochester Hills are named that way for a reason. What is a fun, hilly area to drive is hell under one’s own power. A few miles of uphill with no trees gets tiring quickly.
· The gates at work will not open for a pedestrian or a person on a bicycle, regardless of if a person is swiping a badge or the guard is pressing the button. There seem to be hall effect sensors or something similar in the pavement, and my bike is too small, too non-ferrous, or both. Thankfully an AT&T guy was pulling into one of the data centers behind me, so I just pulled forward until the gate opened for him.
· The sort of crosswalks Rochester has installed on the Clinton River Trail are crap. Here is one. It has a raised median on which it is too small for a bike to stop, but it is ringed with plastic posts making it difficult to traverse in one go. These should be replaced with crosswalk signals and flashing yellows which turn red when someone presses a button. It’d then be easy to cross in light traffic, and easy (despite stopping) if traffic is heavy.
· I could ride to and from work in a reasonable amount of time, but the area near work would make it pretty unpleasant. I’d also be quite stinky and there aren’t showers at work. As I’ve now ridden this route in two separate pieces, one day when I have more daylight available I’ll do it in one go.
· Armhair, particularly mine, is very good at trapping gnats and other small insects when riding through swarms.
· I still don’t feel very comfortable on non-paved areas nor around other people while using pedals which attach me to the bike. I may need to loosen the tension, and I definitely need to work on the positioning of the cleats themselves on the shoes.
· Way, way too many people don’t know how to handle themselves around bike. When someone says “passing on your left”, don’t stop and turn around. Yes, you have the right of way, but you should be reasonably comfortable with where you are as well. You also should be courteous and not take up the whole width of the path with strollers, dogs, or your desire to ride two or three abreast at all times, particularly when you can see people coming in your direction.
