pictures posted on your website inspired me to work on my old bike.
I believe it is a 12 speed centurion. I live in the San Fernando
Valley, California and a single speed bike is ideal for the terrain.
I used the existing 40T front sprocket. Sawed off the 50T sprocket
and used it as spacers. Visited Paul who runs a bike shop near my
work place and installed new inner tubes, tires,chain and a bmx
rear gear. Bought used shimano 105 calipers at e-bay and will install
them as soon as soon as they get shipped. I intend to ride my single
speed to work this summer.
the pictures will be posted in your website.
