Title: Old school chain, how many links?
Post by: paulb113 on January 31, 2013, 05:53 PM: I am getting a 1986 Haro Fst built at the moment and looking to buy a chain for it. the rear freewheel has 18 teeth and I think the chain wheel is 39 teeth. How many links does it need? Some say 110link others 90link.

thanks :)

depends how far back you put the rear wheel. 110 will do you fine, you can always take the spare ones off. Nothing worse than being one link short. 90? sure it doesn't say 96. That's the normal amount. 96 or 110.

If you're going to ride it, probably not.

Post by: Retrodan72 on January 31, 2013, 06:23 PM: Paul what I tend to do is true the rim up to my brake blocks, then push the wheel forward half an inch, them I remove enough links to leave a fairly slack chain. Once linked together and fitted, pull the wheel back to its original position in the dropouts, remembering to centre the wheel whilst doing this.
Your chain should be tight but with a small amount of bounce. Making your chain as tight as possible will destroy your freewheel. :daumenhoch:

39 on the front = 14 on the back mate...... Not 18 ::)

Or 18 on the back = a coping-crunching 49/50 on the front....

Give the pair of simpletons a hug from me will ya ???

Post by: Jaypeg on February 02, 2013, 07:49 AM: I divide the number of teeth on my chainring by 2.75 to get the right size freewheel or just go with what spen said as he is correct ... :daumenhoch:

Post by: paulb113 on February 03, 2013, 10:56 AM: Darren is the front 39? I don't want to have to pedal like mad :LolLolLolLol:

Where is the best place to get a 14t rear one from?

Post by: HEYWOOD BMX on February 03, 2013, 11:19 AM: You`ll need a cassette or flipflop hub to run a 14t rear cog. :daumenhoch:
I have an unused 1/8 14T freewheel you can have for cost of post if you want it....
