Old school gear ratio advice

<< < (5/6) > >>

HEYWOOD BMX:
 :) Thought only AC Racing made a freewheel (14t) to fit regular hubs,they weren`t very durable. Check before you buy. :daumenhoch:

dp and Chopper Dude:
Or if you have spoked wheels, could you use a Chopper rear wheel / hub & use the 3 speed off that? I'll check the width when I get the chance. Hmm I wonder if you can lace Z rims up to a chopper hub  :-\

Threaders:
I want to keep my red tuffs if I can :daumenhoch: Always wanted red tuff BITD :) The gear chart looks cool but  aside from the chainring and freewheel no's, I dont get the other Numbers (the ones with decimal points in) I take it there not miles per hour :laugh:

That's your gear ratio. ie if you went 42/14 it's the same ratio as having 45/15
So if that ratio works for you and your wheel doesn't take a 14t freewheel, go 15 with a 45 front ring!
Hope that helps :daumenhoch:

Threaders:
Aaahhh. I can see that from the chart, but...... What ratio am I after?? Is it the higher the number, the harder you have to pedal by anychance :) IE: 4.5 being harder to pedal than 2.81? :daumenhoch:
