niconj Posted February 22, 2016 Report Share Posted February 22, 2016 Sorry if this question has been posted before, I can't find anything related. I'm in the process of building up an Onza Zoot Pro for which I've got a new frameset pretty cheap. Now I don't want to spent too much money on it and as I still have a fixed rear disc hub and a FFW, I was thinking of putting these things together. Would I get problems with the chain line? If not, what gear ratio is recommendable (FFW is 18T)? Thanks. Quote Link to comment Share on other sites More sharing options...
Dman Posted February 22, 2016 Report Share Posted February 22, 2016 Just put it on the front and sprocket on rear, 18-14. 1 Quote Link to comment Share on other sites More sharing options...
niconj Posted February 22, 2016 Author Report Share Posted February 22, 2016 (edited) True... oh my gosh... haven't thought about this. Still the chain line could be a problem as I need to put in a BB and I don't know if 128mm is too much. What about the gear ratio? 18:14 too small probably.

Dman Posted February 22, 2016 Report Share Posted February 22, 2016 That's how zoots come, ffw, 18-14, it's light but not too bad. Quote Link to comment Share on other sites More sharing options...
niconj Posted February 22, 2016 Author Report Share Posted February 22, 2016 OK. Didn't know that. Thanks a lot. Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 22, 2016 Report Share Posted February 22, 2016 If you're using an 18t freewheel on the rear you'd need to size up to around 23t up front. Stan's using that setup on his Fourplay and it works fine. Otherwise, you'd be needing a 16t freewheel with a 22t sprocket/chainring up front which would boost the cost a bit. If you're running 175mm cranks, I'd go 18:13. 18:14 felt too light to me when I ran it and I seem to remember you were wanting harder gearing on your 26" bike too?

CalopS Posted February 22, 2016 Report Share Posted February 22, 2016 another vote for 18:13 here. Similar to 22:16. Quote Link to comment Share on other sites More sharing options...

Not necessarily but it seems like a good plan. There's plenty of power in my legs with no technique whatsoever. Still indecisive as to build up a Street Trials or a Mod.

Scott Gibbs Posted February 22, 2016 Report Share Posted February 22, 2016 24-18 is roughly the equivalent of 22-16 Quote Link to comment Share on other sites More sharing options...
niconj Posted February 22, 2016 Author Report Share Posted February 22, 2016 If I build up the street trial, I'll be using my FFW cranks so probably going for 18/13. Quote Link to comment Share on other sites More sharing options...
ogre Posted February 26, 2016 Report Share Posted February 26, 2016 you really want a pro2 on it; and then you can go 16-12 for super tiny drivetrain gains Quote Link to comment Share on other sites More sharing options...
