ahhh but thats why i like big chain rings and a racing rear gearcluster for higher top speed... its only easy if you peddle slow. on your bike you hit top speed in what 200 feet??? my beater mountain bike was running 48;16 with the engine bolted to the frame for added weight the rear shifter is dosconected. i adjusted the rear shifter screws last week and am now running it in 48:11 but i now use the front derailer to shift into he smaler chain ring when my backpack is loaded with groceries and im going uphill.... 2:1 for off road nahhh i like speed and jumps and adrenalin
