terry26rims Posted September 28, 2009 Report Share Posted September 28, 2009 I belive you can if it's single speed but i'm sure you'd un screw all threads whilst pedaling. Why would you want to? Quote Link to comment Share on other sites More sharing options...
casualjoe Posted September 28, 2009 Report Share Posted September 28, 2009 If you want to ride backwards trials it would work. Quote Link to comment Share on other sites More sharing options...
Sam Moss Posted September 28, 2009 Report Share Posted September 28, 2009 Have anyone done this?Have you ever watched the top gear where them bmx`s are racing the white fiat? well one of them bikes have it on the left. I dont know how to do it thow. Why would you want this thow? Quote Link to comment Share on other sites More sharing options...
Jack Morton Posted September 28, 2009 Report Share Posted September 28, 2009 It's possiable if you get a LHD hub, Which oddessey ( bmx make ) do , But i dont think on of them hubs could take the amount of stress from trials. Quote Link to comment Share on other sites More sharing options...

casualjoe Posted September 28, 2009 Report Share Posted September 28, 2009 (edited) You could probably gap pretty far backwards with that set up and a bit of practice. it would be like a normal backwards gap but you could put a reverse pedal kick in just before take off.

Ben Swales Posted September 28, 2009 Report Share Posted September 28, 2009 (edited) I looked into doing this a few years ago (I sidehop to the right and was sick of ruining mech hangers etc). The trouble is, the only LHD hubs available wouldn't really stand up to trials riding; the threads on your cranks etc. would be backwards due to swapping sides (and so would come undone/f*ck themselves as you pedalled); in order to run a mech hanger you'd pretty much have to get a frame custom made to have gears fitted on the left etc. etc.All in all I decided it just wasn't worth the bother (if it was, someone would have come up with it a while ago I reckon) and that at the end of the day there was no real advantage to having LHD on a trials bike and just learned to sidehop better.

tkD Posted September 28, 2009 Report Share Posted September 28, 2009 My BMX Had it. You've gotta get a reversed hub though or something along those lines, I personally prefer it as I'm left footed - Handed - the works haha. When I used to ride BMX it made life so much easier for me. But yeah, its very possible Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted September 28, 2009 Report Share Posted September 28, 2009 It is ''possible'' but its so unrealistic its just not worth it. I would love nothing more than a left drive train but theres no real way to do it on a trials bike. For instance like has been said, you need an opposite hub....probably not up to trials use, but even if you used that, what cranks would you run? If you found some left hand drive train cranks they probably wouldn't suit a normal BB so you couldn't run them anyway. SO custom cranks are really whats needed.Also, you'd need horizontal drop outs or a 74Kingz.............so you add it all up and it just isn't going to happen. A lot easier if you wanted on on your BMX however...... Quote Link to comment Share on other sites More sharing options...
WIGAN Posted September 28, 2009 Report Share Posted September 28, 2009 (edited) maybe you could take all your pawls an springs out of your hub and swap them over making into a LHD hub, but then youd still have the problem of your front sprocket unscrewing Edited September 28, 2009 by WIGAN Quote Link to comment Share on other sites More sharing options...
DannyBazz (: Posted September 28, 2009 Report Share Posted September 28, 2009 I saw a kid once with an LHD profile. Limited edition though :/ Quote Link to comment Share on other sites More sharing options...
noname Posted September 28, 2009 Author Report Share Posted September 28, 2009 I guess having chain on left side would be better for left footers, because most of strenght then would go to freewheel when pedalkicking and not to BB. Thus would save some energy. I guess it would be possible if use fixed hub, with threads on both sides, chain would suite. Most problems would be with cranks and freewheel (it would go in opposite direction).Is it possible just put BB otherwise into frame, thus longest end would be on left side and i could put on right sided crank on that left side of bb.Still remains problem with freewheel...

The trouble is, the only LHD hubs available wouldn't really stand up to trials riding; the threads on your cranks etc. would be backwards due to swapping sides (and so would come undone/f*ck themselves as you pedalled); in order to run a mech hanger you'd pretty much have to get a frame custom made to have gears fitted on the left etc. etc.All in all I decided it just wasn't worth the bother (if it was, someone would have come up with it a while ago I reckon) and that at the end of the day there was no real advantage to having LHD on a trials bike and just learned to sidehop better.As I said, Profile would be fine - and there are some lighter BMX cranks out there too. If you got one with a 19mm spindle it might be alright with a Euro BB (aka MTB style), with a ti spindle 'n' stuff. Should work out reeeasonably light, but obviously not as light as a 'normal' FFW setup.I saw a kid once with an LHD profile. Limited edition though :/LHD Profiles aren't limited edition, unless you mean the colourway. Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted September 28, 2009 Report Share Posted September 28, 2009 If it helps my zhi hub has threads on both sides. It was from t-uk but dont buy from them!Heres a link anyway :http://www.trials-uk.co.uk/product.aspx?productid=2281 Quote Link to comment Share on other sites More sharing options...

It was from t-uk but dont buy from them!Heres a link anyway :http://www.trials-uk.co.uk/product.aspx?productid=2281It's a flip flop, not LHD. Means you can have 2 sprockets and just flip the wheel to change the ratio.It's doable! You'd need a set of BMX cranks though I think, and probably a custom sprocket to give you an 18t ring and a bash combined. Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 28, 2009 Report Share Posted September 28, 2009 That's purely for different sizes of freewheel/sprocket, rather than a LHD freewheel/sprocket... Quote Link to comment Share on other sites More sharing options...
sstein Posted September 28, 2009 Report Share Posted September 28, 2009 Technically you could just put your cranks on the wrong side. I know the pedals would be more likely to unscrew themselves, but if you use locktight and occasionally check them it should not cause a problem, just take a while to get used to.However I still don't see the point, most bmxer's who run lhd do so to stop themselves damaging the chain and sprocket when grinding, but that is no problem on  a trials bike as everyone runs a bash and don't slide along walls and rails! Quote Link to comment Share on other sites More sharing options...
Tony Harrison Posted September 28, 2009 Report Share Posted September 28, 2009 If you swap your cranks, the pedals, if anything, will tighten. Think about it. Usually the right-hand crank has a right-hand thread for the pedal, so when you're pedalling forwards it's trying to undo it (imagine the crank as a spanner rotating about the pedal).

Google for thread precession to find out what's actually happening where the pedal thread meets the cranks. Quote Link to comment Share on other sites More sharing options...
