Bill_B Posted March 27, 2007 Report Share Posted March 27, 2007 (edited) Tried searching but I didn't have much luck.I'm building a cheap mod and I have a pair of Truvative hussefelts with 22tooth front chainwheel (fixed) I was planning on using this, but now looking arround realise most mod riders use a gear ratio of about 18:12, here in lies the problem, 12 tooth rear freewheels don't seem to exist. I'd rather not have to buy a new pair of cranks for a front freewheel. So what are my options? I think If I wnt for a 24tooth front sprocket and 16tooth rear freewheel then I would be in roughly the same ratio, or a leave my 22tooth on for starters, I cannot find a rear freewheel smaller than 16t!!!So any advice? I'd prefer not to have to buy new cranks, this is a distinctly low budget build (not got my rear wheel yet, its not arrived, so no idea what is on that).Are mods pretty much exclusively front freewheels or do people use rear freewheels on them?thanks for any adviceEDIT: wheel is a tryall rim with monty fixed hub, so unless I fancy learning to ride trials on a fixed wheel single speed (which I don't ) I need to replace either the rear freewheel or new cranks. IMHO a rear freewheel (providing the hub is threaded) sounds a much cheaper option if possible, or should I just get new cranks and do it properly.

basher Posted March 27, 2007 Report Share Posted March 27, 2007 Yeah you can run a rear freewheel fine alot of the cheaper bikes have that on them. The reason a front freewheel is more popular and is used on more expensive bikes is that it allows you to run smaller cogs giveing you a greater clearance. Also the freewheel on the rear may not be coverved by the dropout so will get a couple of knocks to it where as on the ffw its protected fully. What about the gearing 22:18 is that high enough geared? Quote Link to comment Share on other sites More sharing options...
Lee Cable Posted March 27, 2007 Report Share Posted March 27, 2007 I used rear freewheel on my stock, and it was awesome, ran 22-18. Good decent ratio. Never once hit it. Quote Link to comment Share on other sites More sharing options...
Bill_B Posted March 27, 2007 Author Report Share Posted March 27, 2007 Thanks for the info guys, 22:18 seems to be the 'std ratio' for stock bikes, so I'm assuming going down from 26" wheels to 20"s I'll need to up the ratio a bit. I will try with the smallest rear freewheel I can find first (16t at the moment) and then up the front sprocket if I need to increase the gearing. I'm not too worried about protecting the freewheel and clearance issues while I gain a bit of confidence on the bike, if it becomes an issue I'll put the 12t rear cog back on that I'm getting with the wheel and invest in a 18t front freewheel and suitable second hand cranks....if I ever get that serious So I'm correct in thinking, I should have no problems fitting a rear freewheel to a 19" rear wheel on a mod.Thanks Quote Link to comment Share on other sites More sharing options...
basher Posted March 27, 2007 Report Share Posted March 27, 2007 You will be fine fitting the freewheel to rear 19' wheel Quote Link to comment Share on other sites More sharing options...
