Who would want chrome plated shoes? We do! Not really. Chrome is a brand based in San Fransisco that makes messenger bags and urban cycling apparel. We will be wearing shoes made by Chrome while cycling (not hiking). We will be wearing them for a couple of reasons. First of all, they look cool. Rob has these ones, and Adie has these. They are also great for cycling. They were designed with a much stiffer sole than most shoes, which helps transfer power from your legs to the pedals. This also eliminates “pedal hot-spot,” an uncomfortable burning sensation in the sole of your foot caused by continuous pressure from your pedals. We also got them for free!
Adie had been eying the shoes for a while after they came out, then all of a sudden found out from Rob (and various blogs) that Chrome would be giving out free shoes as a publicity stunt! All you had to do was send in a pair of really beat up old shoes, and they would send you a brand new pair of shoes in your size! Sounded too good to be true, but we both sent off some old shoes. A month later we had heard nothing. Our parents had thought it was a hoax all along, but Adie did some research and found out that Chrome had been swamped with shoes people had sent in, many thousands of pairs, in several full UPS trucks, and were still sorting through all the shoes.
A few weeks later, the shoes arrived, and they have been our go-to cycling shoes for the last year or so.
Our bikes are awesome, you may think, but why would we want these particular bikes on a two month long unsupported bike tour in foreign countries, perhaps in remote areas of those countries, and almost definitely in mountainous areas of those countries? They don’t exactly seem like the ideal choice. And they aren’t.
There are a lot of things wrong with them. Well, not wrong, but less-than-ideal. First, we built them ourselves, with little or no prior experience. There are two issues wrapped up in that sentence. Part A is that we built the frames, using a relatively new and alternative technique, one that we had no experience of, and no-one, except our good friend The Internet, to show us the way. Part B is that we built up the bikes ourselves, meaning we installed all the parts, and didn’t go to a bike store once.
The second issue is a similar issue, also one of quality. We built these bikes really cheaply, probably only spending $300-$400 each (not a bad result for that kind of money, eh!), including the costs of materials and tools. That didn’t leave much to spend on parts.
The third shortcoming of these bikes is the way we set them up, as fixed gear bicycles. For those who don’t know, fixed gear bicycles were the original kind of bike. There is only one gear, and no freewheel. This means that you can neither change gears for riding up hills, nor coast (stop pedaling while the bike is in motion) on the way down. Most bicycles used for bike touring have more than 20 gears, ranging from very low, which lets people crawl slowly up steep hills while lugging around piles and piles of touring and camping gear, to very high, which lets them reach high speeds without having to pedal uncomfortably fast.
- Issue 1 — Part A) bike frames could fall apart — Part B) bike parts could fall off
- Issue 2 — bike parts could cease to function because we didn’t invest in good, reliable parts
- Issue 3 — we will not cover as much distance as a cyclist on a geared bike carrying an identical load
So…Why are we riding the bikes we are riding? There are several answers to this question, and you can read them in upcoming posts over the next few days.
In our first post, we said that our trip is unique in a couple of ways. To sum up, we are riding bamboo bikes, which are fixed gear (meaning they only have one gear, and it is impossible to coast — stop pedalling while still moving — on them), and travelling ultralight (carrying as few and as lightweight items as we can afford to, both in terms of survival/comfort and also financially). This post will touch on why we are riding bamboo bikes, and how we made them.
Our bikes are a bit special, or at least we think so. We built the frames ourselves for a school project in our senior year. It started like this:
In a hallway at Fieldston, our high school.
Adie: Hey Rob, want to build a bamboo bike?
Rob: Why not?
Adie had seen photos of a bamboo bike built by this guy, fell in love, then saw the price tag. Then he thought “Well, I dont see why I cant build one myself.” So he did some detective work, and found a bunch of people who not only had built their own bamboo bikes, but some of them had published instructions. We decided to build the bikes at school as a so called “senior project.” Senior projects are designed to keep very-bored-second-semester-seniors interested in coming to school. People do all sorts of things, we built bamboo bikes.
Why would we want to ride bamboo bikes? Well, a lot of people ask that. We will definitely talk more about this over the coming weeks and months, but here is a short explanation. We think they look amazing (and we hope you agree). They also happen to be one of the easiest types of bike to build yourself (requiring few specialized tools or skills) and they also happen to be very high quality bikes (light weight, responsive, and comfortable). So that was why, and here is how we did it:
We each took an old bike from Adie’s grandmothers’ shed, where they were collecting dust, to use as a donor bike. This bike would provide some parts but also the geometry of the finished bamboo bike.
We ordered bamboo on eBay, then heat treated the poles using a plumbing torch. Heat treating got rid of extra moisture in the bamboo, and also caused a chemical reaction that strengthened the structure of the bamboo.
We then took apart the bikes, using whatever tools we had lying around, most of which were wildly inappropriate for the job, which yielded several large trash bags and a small pile of parts to reuse.
The art department at Fieldston very kindly found us a space of our own to work in, which is visible in photo above. It was an interior balcony over looking one of the art rooms. It was only about 5 feet wide, and after setting up our workbench (made from some junk cabinets and sheets of plywood) maneuvering was difficult at times.
Once the bikes had been stripped down, we set about cutting up the frames. Then we replaced each section we cut out with a matching bamboo section.
Each joint was cut, carved and sanded to fit perfectly at each end. Some joints were bamboo-bamboo and some were bamboo-metal. Certain parts of the bikes simply had to remain steel.
Once we had replaced all of the steel sections of the bike with bamboo, and glued them into place, we set about reinforcing the joints. We bought carbon fiber in string form (rather than woven cloth form), and started wrapping the joints. As we added carbon, we painted on epoxy, which is essentially a very strong two part glue. When the epoxy cures, it hardens around the strands of carbon fiber and creates a very strong and light material (fancy road bikes and Formula 1 cars are generally made from carbon fiber). We each wrapped around 2000 linear feet of it on our bikes, so this stage took a while.
Once all of the joints had been wrapped, we sanded them down until they were relatively smooth and shapely. Then we built up the bikes with a mixture of salvaged and newly bought parts. And TA-DA!
Actually, the story isn’t that simple. We both rode our bikes (very briefly) during the summer of 2010 after having trouble getting parts to work. However between finishing the work on bike frames at school, and the day we considered the bikes finished (when the photo above was taken), nearly 10 months passed. For most of it, we were both traveling, but we finally got together again, with our bikes, in England (where part of Adie’s family is from), in early February. We took our bikes for a ride, and about a mile from home, at the bottom of the first big hill, Robert came suddenly to a halt and said something inappropriate. Adie cycled over to him, and immediately saw the problem. One of the bamboo tubes on his bike had cleanly pulled out of its carbon fiber housing, and was skewed off to the side. We carried his bike the mile back home, and then after some manhandling, were able to pop the tube back into place. We knew then that something had to be done if we were going to ride these bikes for two straight months, several countries from home. So a couple weeks later, after gathering the necessary supplies, we set to work rebuilding the bikes. First we stripped all the parts off the bikes, this time with more appropriate tools, then spent several days sanding the bamboo and the carbon joints. Then we re-wrapped the joints with carbon fiber. We aimed to extend the carbon of the joints to overlap the bamboo by at least four inches at every intersection. The problem area on Rob’s bike had an overlap of just 1.5 inches. While we were redoing the joints, we also made them a lot smoother and more shapely.
It is amazing to ride a beautiful, high-performance bike, and even more amazing to know you built it yourself. We hope these bikes will hold up during our trip, as we know this method of building bikes works.
