Leak only inside the tire First time I inflated it at the gas station (40 psi). The other times I used a small hand pump, that give 20 psi at most (good enough for getting to the gas station) |

How accurate is Google Earth I also made a practical test. I draw a straigh line between two cities (~16 kms apart). With just 2 points, Google gives 13,240 mts. Then I divide each segment in two equals parts and move new points over the road (rinse & repeat). With 9 points, 13,982 mts. With 33 points, 15,044 mts. Finally, with 65 points, 15,502 mts. Now, when I trace a path keeping segments always inside the road (75 points), "real" distance is 16,300 mts. That is just 5% more than the 65 point all-segments-equal-length path. So, it really doesn't make much difference how precise is the path. |

How accurate is Google Earth Google Earth measure distance on the horizontal plane (I tested it). However, difference is minimum. Example: a 300 mts high hill with a 4,000 mts long straight road (my tipical ride). Google Earth gives 4.000 mts, but trigonometry say 4,011 mts. Less than 0.3% difference. Also, I draw my path inside existent roads, adding as many points as necesary to stay inside the road. Now, supose we ride tracing a sine wave with 1 meter amplitud (to each side) and 40 mts "wave lenght". So, for a straight 40 mts path, we travel 40.2 mts total. That's a mere 0.5% difference. |

Would hydraulic disc brakes be easier on my hands than mechanical disc brakes? Brakes are Shimano Alivio. Age 3 or 4 years (bought second hand). I have made near 2.000 kms. Never changed pads; they look good to me. They work well; just need lot of pressure for complete stop while running downhill (~30-50 k/h). I changed the cable casing for a new one (teflon inside). My handlebar is narrow (shoulders wide) and my setup oriented to minimize weight on my hands and get an upright position (I weight 100 kgs). As I said, I enjoy looking the landscape. I do basic maintenance myself, but take it regulary to my mechanics. |
