I’ve been biking in Memphis for more than three years now. One thing is for certain when commuting in Memphis — you’ll get lots of flats. Street cleaning is minimal, broken bottles abundant and invisible shards of shredded steel-belted radials are everywhere. When I was using my road bike to commute I chose the expensive yet very tough Specialized Armadillo tires. The Armadillos were a pretty good tire and prevented most flats. They once even deflected an 1/8 inch drill bit which lodged in the rubber of the tire and spun around a few times scoring my frame — but no flat. However, the Armadillo was no match for the shredded steel-belted radials.

I switched to my mountain bike after a year on the road bike so I could take to the sidewalk on the busiest road I traveled. Slicks were out of the question since I often road in wet weather and in grassy areas. Nobbies were the answer for me. It allowed for good traction in all conditions and kept the casing and tube further off the ground and away from the road cacti. Despite the choice of nobbies, flats were still a common occurrence. That’s when I decided to switch to a Slime-filled tube on the rear tire.

I have not had a flat with the 26″ Slime tubes after about 2500 miles of commuting on them. I did have a puncture once that I heard and for which I stopped. It didn’t appear that the tube was sealing so I passed my finger over the hole as the Slime was seeping out. Upon doing this, the leak stopped and I haven’t done anything with it since.

It is noticeably different riding the Slime tubes. Mostly, they make you noticeably slower. These things do not roll well. However, since I’m so tired of flatting after 3 years, I’m willing to sacrifice the performance. And, I only use the Slime tube on the rear wheel as it flats far more frequently than the front.

I’ve also recently started riding a 700C Slime tube on my road bike. My first long distance ride in a while resulted in two flats on the Slime tube. One flat resulted from a small, sharp unidentifiable object. After several attempts at reinflating the tire, I was able to get about 80psi in the tire — just enough for me to reach the half-way point stop. However, prior to arriving at the stop, the tube flatted again. This time it was an all-to-common steel-belted tire shard. Although only a pin prick hole, I could not get the tube to hold pressure and I was forced to install my spare tube. Pulling the Slime tube was fun to say the least. First there’s the green goop everywhere, which happens, burns like hell when you get it in any open sore. Then, trying to fold the Slime tube up into a reasonable size to stuff in my Camelback proved almost impossible since the Slime seals the valve rendering it impossible to fully deflate the tube.

Conclusion: Slime-filled tubes work well for lower pressure tires like MTB tires but they do not suffice for high pressure tires. Thus, don’t buy the 700C Slime-filled tubes.

I don’t think bike commuting helps make friends in every city or community but it sure helps here.  Using my bike almost exclusively for transportation in the city of Memphis makes me a bit of a novelty.  Given that midtown Memphis is a pretty diverse place and there are a lot of bike commuters, I’m also not hated for being one that impeeds traffic.

Almost everywhere I go, people talk to me about commuting on a bike.  I have people at intersections roll down their window, usually to ask me a question about why I’m out on a bike.  I just started at a new gym and while very few people want to talk at 6:30am, the fact that I walk in wearing a bike helmet seems to be a great conversation starter.  Sure, most conversations center around the weather for that day but at least people feel compelled to interact with me.  These situations just confirm my belief that bike commuting makes for stronger communities by stimulating people to interact with each other.

I’ve been using my Forte Single Speed Conversion Kit (www.performancebike.com) for about 9 months now. It is still in reasonably good shape and functions. I can’t say that I’m extremely satisfied with it though. Here are my reasons:

1. The tolerance between the bolt and and the tensioner arm is loose and doesn’t get better with use. Therefore the pulley sits on the chain at an odd angle.
2. There is a cage around the pulley to keep the chain from coming off of the pulley. The axle bolt for the pulley comes loose frequently and alloys the cage to rotate and hit the chain. You have to stop and tighten the axle bolt. Sucks!
3. I thought that since I was going single speed in the back there’s no use for a front derailleur so I removed mine — mistake. Without the front derailleur, curb hops and off-roading sometimes sends my chain to the bottom bracket or my pedal spindle.
4. If your hub body is anything other than steel, the kit is not a good idea. You only put one cog on the back and the cog’s interface with the hub body is very small. Thus, with my aluminum hub body, the cog ate half-way through the hub-body splines — not good if your attached to your hub (mine is 12 years old with roughly 10,000 miles on it). I had to put on an old cassette to spread the load.
5. The spring tension isn’t great or adjustable. So, if your chain happens to be a bit on the long side and taking one more link out makes it too short, your chain may just skip over your cog.

It’s great to be free of a derailleur and all of its problems but the conversion kit needs some design iterations.

Things I Bought for Biking (that I can remember)*:

2 pairs of shorts (baggies), Two poly shirts, 3 pairs of socks, 2 chains, 2 pairs of pedals, numerous tubes and patch kits, 1 pair cranks, 1 bottom bracket, one rigid fork (the suspension was warn out), 2 rear tires (my front tire is about 5 years old and has about 8000 miles), 1 saddle, 2 rear lights, 2 front lights, two boxes gauze pads, 2 boxes band aids, two rolls medical tape, 1 tube of triple antibiotic goo, 1 pump, 1 rear hub rebuild kit, 1 single speed conversion kit, 1 brake cable kit, 2 sets of brake pads, 1 set of brake levers, repair of internal hub (I messed it up trying to adjust it), one rear fender, reflective tape, 1 pair shoes (my others were 6 years old)

Keep in mind that this was not my first year of commuting.  Most of these purchases were required just to maintain the bikes.

A lot of people, when becoming aware that I bike commute, say, “How do you bike commute in Memphis!? Drivers here are terrible and the roads are busy.” Until recently, I couldn’t understand why they would say that, other than they haven’t been on a bike in the past 10-20 years. Then I realized, “They only know the roads that they travel by undesirable vehicle to get from point A to B.” Now I know why they think I’m crazy. They think I ride my bike on the busiest roads in Memphis.

The fact is, I rarely get passed by cars with less than ten feet of distance between me and them. Okay, the distances are closer towards intersections but the passing cars are traveling slowly. I take a wide range of streets to get to and from work. Some are always lightly traveled, some are heavily traveled and some are walks (or rides) in the park. I know what the busy streets are. My friends who drive to work take them. I take the back streets. In town, that’s easy. There’s a thousand different ways to get to work, many of the ways on back streets. I also ride through a local and very historical park. On the one busy road I have to take, I utilize the sidewalk. First, it’s my understanding that in Memphis you can legally do that and second, since no one else is using it (they’re sitting inside watching tv or driving their undesirable vehicle), I might as well.

It’s taken me a while to find the best route to work. Just two weeks ago, after commuting for almost two years, I found a small but very meaningful shortcut through an abandoned airport parking lot, over a small wooden walking bridge and through the parking lot of a career college. I couldn’t believe I had just found such an obvious short cut after more than two years. But finding the right route has been a progression. When I first tried out the commute on a Sunday morning to determine it’s ‘doability,’ I took all of the major roads. That’s fine for Sunday morning but spine-tingling on a Monday morning or Friday night. As I’ve learned the streets of Memphis more and more, I’ve change my route. My route evolved twice within the last two months, each time becoming more safe.

So what do I recommend? Well since even people living in the areas you intend ride through probably don’t know all of the streets and won’t know how to connect them for a safe and comfortable commute, I recommend this: Take several weekend scouting trips, each time selecting different routes. Don’t select roads you know will be heavily traveled during the week. Stick to the parks and small neighborhood roads. If your only option for one section of the commute is the sidewalk, I recommend taking it — at least someone will be using it then. Select your final route based on low traffic or smaller hills or just by areas you enjoy seeing. And, your route to and from work may be different based on traffic flow.

Starting a bike commute, if you haven’t done it before, needs to feel safe and comfortable. To achieve this feeling, good preparation and a little weekend scouting will not only be enjoyable but ensure your commute will get you to work in one piece.

Note for web developers: If it hasn’t been done already, a Mapquest-like search tool that not only eliminates the highways from the search but also allows the searcher to identify very lightly traveled streets would be an excellent tool for bike commuters. (Remember, it’s taken me two years to develop my current route, and I can’t be sure it won’t change again.)
