o0jack0o Posted July 12, 2012 Report Share Posted July 12, 2012 Hi, so i just bought a seemingly good bike off ebay for trials and have now found out that it is a fixed wheel! Basically is there a way i can make it a freewheel bike? Can i just replace the hub (i think - inside of the wheel middle) for a freewheel one and also get the cassette to freewheel? urgent response please! Thanks jack Quote Link to comment Share on other sites More sharing options...

isitafox Posted July 12, 2012 Report Share Posted July 12, 2012 Is there a freewheel on the cranks by any chance? Quote Link to comment Share on other sites More sharing options...
o0jack0o Posted July 12, 2012 Author Report Share Posted July 12, 2012 erm, not sure, when i spin the pedals the cassette moves with them and stops with them so i assume no? Sorry not the best bike mechanic as my dad does most of it =s Quote Link to comment Share on other sites More sharing options...
ghostrider88 Posted July 12, 2012 Report Share Posted July 12, 2012 (edited) Is there a freewheel on the cranks by any chance? Looks like there is I think. Edit,when you spin cranks back,does the rear wheel move or they spin freely? Edited July 12, 2012 by ghostrider88 Quote Link to comment Share on other sites More sharing options...
o0jack0o Posted July 12, 2012 Author Report Share Posted July 12, 2012 Rear wheel is off now but yeah spinning either way resulted in the wheel moving in that directing. Quote Link to comment Share on other sites More sharing options...
isitafox Posted July 12, 2012 Report Share Posted July 12, 2012 I'd assume, as it looks like it to me that you have a front freewheel fitted, that the freewheel has seized up. Can you get some close up pics of the cranks? Quote Link to comment Share on other sites More sharing options...
ghostrider88 Posted July 12, 2012 Report Share Posted July 12, 2012 Rear wheel is off now but yeah spinning either way resulted in the wheel moving in that directing. Ok,so last attempt,try to turn front sprocket,if it´s freewheel it will move relatively easy(but hold the crank still so it won´t spin with the sprocket/freewheel).

o0jack0o Posted July 12, 2012 Author Report Share Posted July 12, 2012 Sorry can't get any more photo's as my dad has gone out with his phone and not got another camera here. Will have a look though i may not be able to do much Ok,so last attempt,try to turn front sprocket,if it´s freewheel it will move relatively easy(but hold the crank still so it won´t spin with the sprocket/freewheel). Ok will go try this Quote Link to comment Share on other sites More sharing options...
Jake. Posted July 12, 2012 Report Share Posted July 12, 2012 If the front sprocket is small 18t and fat (width) its a front freewheel. Quote Link to comment Share on other sites More sharing options...
o0jack0o Posted July 12, 2012 Author Report Share Posted July 12, 2012 Ok so i tried spinning the cranks in reverse and holding the sprocket but it wont budge an inch but i may have found the reason. Looking at the inside part of what may be a freewheel the plate has partly come off i.e 1mm and i can see some ball bearings!!!!! It looks as if some have got out as there are some gaps. Very angry witht the seller who said it rides like a dream yet when arrive i had to replace the bracket hanger for the deraileuar If the front sprocket is small 18t and fat (width) its a front freewheel. Yes it is fat and looks like it is a freewheel Quote Link to comment Share on other sites More sharing options...
Jake. Posted July 12, 2012 Report Share Posted July 12, 2012 Then it probably is, most people wouldn't sell a bike with a fixed hub and fixed sprocket unless they're a f**kwit. Quote Link to comment Share on other sites More sharing options...
bike_dummie Posted July 12, 2012 Report Share Posted July 12, 2012 Of topic but what frame is that? Quote Link to comment Share on other sites More sharing options...
o0jack0o Posted July 12, 2012 Author Report Share Posted July 12, 2012 I assumed it would be freewheel which perhaps i should have asked but as none of this was on the description i agree with you. So far list of what i consider problems should have been mentioned: 1. Broken hanger bracket 2. Broken front freewheel 3. Fixed wheel!! Really pissed offff - any suggestions on getting new front freewheel and how to change the rear one to freewheel? Of topic but what frame is that?

harmertrials Posted July 12, 2012 Report Share Posted July 12, 2012 You want a rear fixed wheel with a freewheel. I reccomend buying a new freewheel (pick up an echo sl off here) and getting a new sprocket for the rear to replace that cassette. Also a sprung tensioner Quote Link to comment Share on other sites More sharing options...
isitafox Posted July 12, 2012 Report Share Posted July 12, 2012 The rear is supposed to be fixed, just buy a 2nd hand front freewheel off here or buy a new one from Tartybikes, they may have the correct mech hanger for you as well. In terms of what freewheel to get I'd suggest either a Tensile or Echo SL. Quote Link to comment Share on other sites More sharing options...

Also is the front freewheel hard to replace?

Ok, would probably get a new front freewheel from tarty and fit that, would that then mean i just need a new rear sprocket for it to work? Also got the mech hanger so that fine thanks heres the webby if anyone needs as really good service,great range and is CNC - http://gearmechhanger.com/ Edited July 12, 2012 by o0jack0o Quote Link to comment Share on other sites More sharing options...
isitafox Posted July 12, 2012 Report Share Posted July 12, 2012 Depends, if the rear cassette has a 15t sprocket on it then use that gear with the FFW. If not then buy a 15t sprocket and single speed spacer kit as well, will probably also benefit from a proper chain tensioner though that rear mech locked out will do the job if money is tight.

harmertrials Posted July 12, 2012 Report Share Posted July 12, 2012 You can indeed use your current rear wheel. It's no essential that you change to a singlespeed setup (removing the rear cassette and replacing with a 15t sprocket), but it's the norm in trials, knocks weight off too. Shouldn't be too hard providing that it's a splined hub (check www.tartybikes.co.uk if anything I'm saying goes over your head and you'll soon figure It out). As for the freewheel, probably best you send it to tarty to remove as they are a tricky bugger Quote Link to comment Share on other sites More sharing options...

Thanks, so the simplest (Cheapest) option would be to use one of the current if 15t (if not buy one) sprockets and use single speed spacers so the others can be removed and then also replace the FFW?

ogre Posted July 12, 2012 Report Share Posted July 12, 2012 1.you may find removing the freewheel is difficult/impossible tarty offer a removal service if you're struggling. 2.you will break mech hangers all the time, don't buy an expensive CNC'd one, get on the blower to tarty and work out the type you need (probably a K type) buy 2, one for a spare and make sure the seller refunds you for one of them... 3. your current mech will work fine for a tensioner, but if you want to save some weight and have a neater set up, buy one of these tensioners, they are the best performance/value out there, avoid the single wheel tensioners, they suck! 4. if you can run a singlespeed sprocket with a wide base, to protect the hub, you'll need some spacers in order for it to work right though. although this will run up a fair bill, trials bikes are relatively cheap to maintain compared to other disciplines.... happy riding!

Thanks, did get him to refund him for the hanger and just let him know how unhappy i was with the problems and he has just offered full refund less postage...looks like i got to weigh up the costs of fixing it Quote Link to comment Share on other sites More sharing options...
