Miss-Higgy Posted May 7, 2012 Report Share Posted May 7, 2012 Just an idea me and my other half have been kicking about. And having looked at the hub and realising that i could quite easily fit a rear freewheel. What would you guy's say are the Pro's and Con's of doing this, also what freewheel would you recommend when doing this. And would this eliminate the need for a bash plate/ring? Main reason for asking is i really want to run a set of middleburn's and i know damn well i can't with a front freewheel.

isitafox Posted May 7, 2012 Report Share Posted May 7, 2012 (edited) You'd still need a bashplate or ring and you'd have to run a bigger than normal sprocket up front. Your best bet is trying to get hold of a profile or chris king freehub. Otherwise you want a 16t freewheel at the back and a 22t up front I think.

Jamie_Trials Posted May 7, 2012 Report Share Posted May 7, 2012 I wouldn't recommend it at all, most of the 16t freewheels are made of poop, if you really want to run middlesburns then you'd be best off getting a freehub, profiles are fairly cheap 2nd hand last time i checked. 1 Quote Link to comment Share on other sites More sharing options...
ogre Posted May 7, 2012 Report Share Posted May 7, 2012 with an 18t sprocket on the rear you'd need a 27 tooth sprocket up front to get the same ratio as 18 12 which would be hard to get for burns... you'd still need a bash ring, to protect the chain and sprocket...

mr_malcolm Posted May 8, 2012 Report Share Posted May 8, 2012 other then for cosmetic reasons why are you so adamant you want to run middleburns? providing you maintain your cranks they all do the same job. Im a big guy and rode a set of basic onza muscle man cranks on a mod for 2 years when i rode. just make sure you check cranks bolts etc when you ride. Also has been said most rear freewheels are shite you would need to get a freehub if you want something you can trust. Quote Link to comment Share on other sites More sharing options...
Miss-Higgy Posted May 8, 2012 Author Report Share Posted May 8, 2012 Was just an idea as we have two pairs of middleburns available for use, and I've been trying to find any way of getting my mod built and finished. Have realised the flaws of rear freewheel now. But thanks for all your help anyway guys Quote Link to comment Share on other sites More sharing options...

Last I checked freewheels are freewheels whether you choose to screw them to your crank or hub. There are a few reasons to put a freewheel on the cranks rather than the hub but increased reliability is not one of them. Saying this however, I also do think freehubs are more reliable than freewheels but that is a seperate issue. Quote Link to comment Share on other sites More sharing options...

Its been a long time since ive used a freewheel and a long day it work is making my brain struggle to engage properly at the moment. Quote Link to comment Share on other sites More sharing options...

No. Threads are the same but the freewheel would be flipped over, hope that makes sense 1 Quote Link to comment Share on other sites More sharing options...
Sherb Posted May 10, 2012 Report Share Posted May 10, 2012 Im running middleburns trials pro 22T to 16T rear mounted Viz 72 freewheel.(24") which is working out a great ratio for general/natural trials but slightly too low for street i think, depends on your riding style. I though the main reason for putting freewheels on the the front was for additional clearance if your bike had a Low BB. other than that, lossing a couple grams and not moving the chain when back pedaling I see no Difference in performance. If your left foot forward... why dontcha get real crazy and flip the wheel/ freewheel and cranks round and run it on the back and non drive side! funk the norm!

bing Posted May 11, 2012 Report Share Posted May 11, 2012 (edited) on my rock man 108 sl, the lockring is fastened on clockwise, so on ffw will stay tight. if it were on the back, it will become loose. an acs claw lockring is threaded on left hand, so would come loose on the front, I know this cos I had one. they are advised for rear use only because of this (null) Edited May 11, 2012 by danchandler Quote Link to comment Share on other sites More sharing options...
sstein Posted May 12, 2012 Report Share Posted May 12, 2012 that is just cause people dont maintain their bikes Quote Link to comment Share on other sites More sharing options...
