Post by: pickle on October 28, 2011, 01:37 PM: 14t i think but you'll need a flip flop hub with micro threads :daumenhoch:

if its got a 16t on then its a big thread and wont get a 14t freewheel on

if its got a 15t on then its a small thread then you could use a 14t freewheel

Post by: Spen69 on October 28, 2011, 02:09 PM: I did a thread about this a while ago now as I run a 13T Oddysey freewheel on my park bike with a 36T drive at the front - I'll dig it out an post a link up, but you need a flip-flop hub.

Best thing is, you can keep the old-school look about the bike, but with the mid-school, lmost new school coping clearance (which is why I assume you're asking?)

Here's my bike now as it looks - you'd not know until you look closely at it :coolsmiley:

And here's a close-up of the freewheel so you can see the flip-flop hub :daumenhoch:

If you don't have a flip-flop, you're stuck at a 15T if you can find one, and it might be worth buying a new hub and lacing it in or even a new wheelset I'm afraid :-\

Post by: motomagII on October 28, 2011, 02:15 PM: thats the beauty now a lot of people have said in past the 13t ones are shite as they arent very strong because of the size but ive been running one for over year and riding 2 or 3 times a week on track and until last week had no probs with it so i reckon a year on a 15.00 freewheel is acceptable to me .
i have now ordered a white industriesw 16t though lol

Post by: pickle on October 28, 2011, 02:17 PM: if it's for a race bike then i don't see the point in going all micro geared :-\

16t and 44t work just fine for a track bike.

Park bike? now that's a diferent kettle of fish

Depending on the brake location on the dirtbike, make sure the chain will clear the brake before you go for anything less than a 13T

Post by: hunterdubber on October 30, 2011, 05:14 PM: DK made a 12T freewheel for use on a flip flop hub once upon a time ( 3 or 4 years ago)

That's definately the smallest I remember made ???

11t casette hub with chainstay mounted brake you have to have a constantly super tight chain so as to avoid any chain rub issues as Diggs mentioned

Like Gary says you can get a full wheel/set with 9t casette hub for mucho dheapness these days ;)

Post by: billstup on October 30, 2011, 06:03 PM: Smallest for a normall hub is 16 teeth, there were some 15t about but they broke easy, for a flipflop hub it`s 13t, but like Tom said check where the brake stays are because if they are on the chain stays and not the seat stays then sometimes the chain will hit the brake :-\
