Lhd ?

HI

Is there any company's out there that make heft hand drive hubs etc for trials or even jump bikes.

As far as i can see there isn't any thing out there.

I have run my Bmx LHD for years now and because i go to the right it cuts out so much hassle with the drive train. sourly this will help with the smashing your mech hanger off problem.

I for one would definitely run my trials bike LHD if I could.

If you can find Tandem Cranks that take a 22T chainring and a BMX LHD hub you might be able to make something with stock parts on a modstock frame or a mod. Running a RH crank on the left will leave the pedal working loose on you all the time (Wrong thread direction).

Presumably you're happy enough with the LHD freewheel you have on the BMX to trust it for trials? Finding cranks with a LH thread for a freewheel on the left crank may be possible if you want to try that. If you can get a LH thread crank you could run a fixed ECHO hub flipped over with the built in tensioner and you're sorted - big if on getting the cranks though...

LHD bmx usually uses a cassette hub not freewheel ;)

PROFILE they make a singlespeed hub for 135mm axles and pretty positive that the pawls in the freehub can be reversed and ran as lhd

I somehow doubt it will be suitable for a trials bike and it probably will only have 20 odd engagement points......

Gogz don't bother, it's too much hassle and it probably will be shite anyways. Just put some decent brakes on the BMX and use it for trials ;) haha

If you locktited the pedal in (and kept checking it) you could use flipped cranks, with FFW. Difference is, the FFW's teeth for putting it on/taking it off would be facing at the cranks, so it would never come off.

Loctiting won't help the pedal stay in at all. If you take a pedal off a bike that's got a lot of miles on it you'll see that the pedal axle has chewed it's way into the crank over time. This is because the thread direction causes the pedal to tighten as it's used (Due to a phenomenon known as thread precession). The forces involved in precession in pedals are much higher than loctite can resist. Machining a 45 degree taper after the thread on the pedal and a matching taper on the crank will potentially allow you to run a RH crank on the left. Of course the threading direction for a freewheel and the freewheeling direction will be wrong, and loctite definitely won't hold a freewheel with reversed pawls onto a crank...

A Echo 135mm fixed hub, Southpawl 1/8th freewheel and flipped Echo cranks? [edit] or light bmx cranks with 22t sprocket?

It sounds like more effort that it's really worth. Or more money and time than it's worth.

Maybe just a normal drivechain setup with a beefy tensioner and steel hanger?

But when you pedal forwards nothing would happen?

but you could ride backwards everywhere, if thats what you like..

It would be nice if there was a LHD option available.

I should technically sidehop to the right and I just know I'm gonna go through loads of mech hangers when I try and learn.

I like the idea of that Onza prototype frame with the chain stay lowered to protect the drive.

I think these Pashley forks are probably aimed more at street riders doing drop-out stalls who want to run a front disc and have the choice of which side they go to. Not strictly an issue in trials. I've never had an issue with which side my disc is on affecting the way I ride.

Has nobody thought to learn every move in both directions? You're only half the rider you could be otherwise.

Lots of BMX'ers learn tricks both directions. Like 360's both directions, tailwhips both directions etc. Takes a hell of a lot a skill to learn tricks 'goofy' style though.

I saw a BMX video the other day and the guy just rode along and bunnyhop tailwhiped one direction, and then he bunnyhop whipped back again :huh: frikkin amazing amount of skill.

indeed, spinning oppy is savage at pace.

Mainly because your feet are in the wrong place for scooping the bike around.

but yes i hear the arguement. i try and make sure i don'tt have a 'dominmat' direction but it always ends up being one favoured side :P

probably because im still sh*t
