bikeperson45 Posted January 25, 2011 Report Share Posted January 25, 2011 About why what is done? Trials? About the freewheel being front or back. Most people seem to say front these days, personally I prefer rear but I think it's mainly personal preference. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted January 25, 2011 Report Share Posted January 25, 2011 Centres the weight Quote Link to comment Share on other sites More sharing options...
Revolver Posted January 25, 2011 Report Share Posted January 25, 2011 On a mod to run a massive chainring means a lot less clearance underneath. Stock riders have been adopting it because it moves the weight into the middle of the bike, like was mentioned above. Quote Link to comment Share on other sites More sharing options...
CalopS Posted January 25, 2011 Report Share Posted January 25, 2011 front just make sense unless you doing streety stuff where you need the cranks to stay still. Quote Link to comment Share on other sites More sharing options...
Jon Alty Posted January 25, 2011 Report Share Posted January 25, 2011 Also i think because on mod, the common ratio is 18:12, and a 12T freewheel is harder to build than an 18T. Quote Link to comment Share on other sites More sharing options...

JD™ Posted January 26, 2011 Report Share Posted January 26, 2011 That's not how gear ratios work. He means that's why it's on the front, on the 18 tooth part of the ratio, rather than on the back on the 12t part of the ratio. Not that you could swap them round and they'd be the same Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 26, 2011 Report Share Posted January 26, 2011 It's a lot cheaper getting a good FFW setup compared to a freehub setup with comparative performance. Generally it's cheaper to get a light FFW setup. Wider choice of FFW bits compared to rear freehub or rear freewheel. Smaller and more compact. Shifts weight towards the centre of the bike. Theoretically means that your chain is constantly tight when you're rolling forwards (because of the freewheel spinning the chain) meaning you don't have to pedal through any chain slack before you start engaging the freewheel.

If you wanted to run your standard 18:12 gear ratio, your going to struggle to find a 12T freewheel to put on the back, where as its really easy to get 18T freewheels, for the front. You could i guess put a 16T on the back and then a 19/20 on the front, but then you get less ground clearance so. Most cranks take FFW now so why not Quote Link to comment Share on other sites More sharing options...
