Anyway, as long as we are talking about speed, this past week I took my youth group to a mission trip in Pittsburgh, PA. As we loaded the trailer with luggage I threw in the closest bike available, a Schwinn Prelude with an Aerospoke rear wheel that someone gave me. I had recently put 90psi in the tires (I know they are suppose to be at 100 or more, but I couldn't let myself do it). Since I was given this bike all I've done was swapped out the Look clipless pedals for platforms and put air in the tires. The Aerospoke has a little play in it.
So we get to the church where we would be staying for the week in Monroeville, PA. It's hilly here... I had no idea.
Tuesday morning I got up at 5:30 and got on the bike wearing cargo shorts, a t-shirt, and Converse all stars and I hit the road. I went uphill since I would rather return from a trip coming down than up. I got to the peak of a hill at speed at a 3 way stop and since nobody was around I blew right through. Let me add, I've never really had a road bike, as a kid I would ride 10 speeds if I had to, but I liked BMX, beach cruisers, and mountain bikes. The fastest documented for me was about 32 on my Trek 7000 mountain bike, then I crashed and got 14 stitches. More recently I puzzled as to why I couldn't get over 27 on my Gary Fisher mountain bike on a slight downhill.
Anyway, this hill ended up being steep, before I knew it all I could hear was the rush of wind blowing past my ears like my head was stuck out of a car window on the highway. My vision went blurred because the cool morning air blasting into my eyes made them water. I reached up wipe my eyes just in time to see the next 3 way stop... I didn't see anyone, so I pedalled... WHOA! I don't know how fast I was going, but soon I got to the bottom of the hill and the last 3 way stop, I had to blow this one, I didn't have enough brakes. I was scared the whole way down because someone else built and maintained this bike.
I would do it again... with a helmet on, but I didn't ride anymore the rest of the week and thought about putting the bike on the Pittsburgh craigslist thinking I might get some money for it there since nobody would buy it around here.
I need to see about tightening up that Aerospoke, now I wanna go fast again... too bad we don't have hills like that around here.
