terry26rims Posted November 16, 2009 Report Share Posted November 16, 2009 i have been thinking about changing my sarcacen flea 4 to ffw, my step dad asked why and i dribbled off about weight saving and ground clearance could someone explain to true advantages of a ffw?

forteh Posted November 16, 2009 Report Share Posted November 16, 2009 The lightest FFW setup isnt any lighter than the lightest king setup (there isnt much in it though), what it does do is move the weight of the ratchet forwards off the back axle to give a more neutral centre of gravity; a ffw is also cheaper to replace than a king.However if you currently have a freehub then you will need a new rear hub (plus associated wheel rebuild), new set of screw on cranks, bashguard, screw on sprocket and the freewheel.

Token Posted November 16, 2009 Report Share Posted November 16, 2009 If you're already setup with a rear freewheel, the cost vs advantages of changing to FFW is rubbish. There are pros and cons of both front an rear freewheel but to just justify going from FFW when you've already got a RFW setup it's just stupid.

JT! Posted November 16, 2009 Report Share Posted November 16, 2009 The biggest advantage for me is that the weight is centered. When i went from a profile to a ffw the wight off the back wheel was just so nice. Quote Link to comment Share on other sites More sharing options...

Depends how you play your cards I guess.Which rear hub are you using at the mo? Quote Link to comment Share on other sites More sharing options...
terry26rims Posted November 16, 2009 Author Report Share Posted November 16, 2009 it's a echo tr with 18t dicta free wheel. Will a a tensile freewheel hold tight? Quote Link to comment Share on other sites More sharing options...
psycholist Posted November 16, 2009 Report Share Posted November 16, 2009 Starting with a screw on rear hub you can still use that, but you'll need new cranks and a 15T screw on sprocket (To give the most common ratio for a stock bike, if you ride a Mod you'll need a 12T screw on sprocket). Make sure the BB you have is long enough to have room for a FFW as well - certain combinations are known to have issues.I'm not too sure about the strength of the Dicta freewheels, but putting it on the front will load it slightly more heavily as the gear ratio multiplies up the torque seen by the freewheel, so if the freewheel you have already needs a lot of attention to keep it running it will need more on the front.

duncan_echo26 Posted November 16, 2009 Report Share Posted November 16, 2009 What size chainring have you got on the front just now?If its a 22 tooth then all you will need is a freewheel.22-18 is pretty much the same as 18-15.I would recommend just getting a new freewheel and putting it on the rear.
