yeah i like fixed! but riding downhills fixed definitely seems to be the hardest part. i mean riding slow downhills would be no problem but wheres the fun in that????
lately i been learning to just let my legs go limp and use the front break for control. i am still not as fast as on my freewheel bike but i am working on it. i always wonder what cars think when they pass me going downhill legs spinning at mach12....
igloo - if you didn't already know you can just count the teeth on your cogs to figure out the ratio. according to the website it's 42x16. not too bad, but maybe a little steep if you have any big hills.
i currently ride 44x17 freewheel and 46x18 fixed. i can keep up with geared people OK but with faster riders i really do have to spin quite quickly.
