I have a very old school fixed bike all steel except the bottle cage. It is a pre WW11 track frame and in nice shape. The rear hub(1930's) is fixed/fixed currently fixed/free 14/16, I have fixed in 14,16,18,20 extras. Rims are 28" (700c) steel with cool old style tires 28 x 1 3/8 x 1 5/8. The seat is Brooks B5 from 1930's. Bars are from 50's British bike. Bike never came with brakes I added them from 50's British bike, I added them when I put the freewheel on. I will go back to fixed/fixed soon and no brakes. The cranks are from 60's 10 speed with 50 tooth, I have extra chainrings in many sizes. The bike has eyelets for mudguards and I have both black and cream Bluemels mudguards for it. The bike is not light but a fun bike to ride. The bike is used for summer evening and weekend riding, I don't live in the city and commuting is not easy for me as I would have to ride busy highways in dark both ways. On my Sunday rides I usually put on 40 or more miles. I have a few more fixed bikes I am working on and will post them in time.
