Because I ought to be doing something much more important, but don't want to, I am wasting time planning a new build with left-side drive. Anyone done one? I'm thinking about just swapping the cranks over and thread-locking the fuck out of the pedals to stop them unscrewing, then turning the back wheel around and hoping the lock-ring holds.

Obvious refinements would be using a sync crank from a tandem so the pedal threads are correct, and using one of those left-threaded BMX hubs. But I am quite lazy and would rather risk a massive mechanical failure leading to serious injury than go out and find the correct bits.

Any thoughts? Sheldon built a left-drive bike with a SA 3-speed hub, but then went and died without writing a long essay on the intricacies of doing it, the lazy fuck. (RIP).

pedels will unscrew too.

Why would you want to? Benefits are clear for BMX, but it's a lot of faff and inconvenience for nothing in my opinion.

forget left hand drive goo look for belt drive.

Respect.

Ive always wondered if theres a quantifiable difference to which side your drivetrain is on.

Technically it shouldnt at all sureley?

But at the same time I find the thought of riding with everything on the left truly abhorrent!

In terms of hubs, a bmx one wont help as you cant get it fixed gear right?

What you need is a fixed gear trials hub, they are similar build quality to goldtecs but half the price, they also have genius splined sprocket fitting which is the key to your success!

Mate did that mtbstyele

B ad mofo eventually.

front disc hub conversion to fixed gear with spacers and axle to fit rear dropouts. makes no difference which way you run it then.

really, what's the point?

Just for fun.

I once saw a tandem classic campy crank for sale on e bay, it was identical to the old campy track cranks, really kick myself for not buying it.

If your just using normal cranks with the pedals glued on you have to swap the spindles in the pedals so there facing forward

for hubs use a level or some sort of bolt on cog to a disk hub and it should be fine

put yer cleats on backwards :)

it's a ball licker.
as in "why do dogs lick there balls"

answer
"because they can"

I would do it. I'm left-handed, so the idea suits me. Plus it freaks people out, but it's so subtle they don't know what's bothering them.

+1 rather than putting all the strain on the lock ring.

my dog can't lick his balls.

cos i had them cut off.

bet he still try's though.

yeah....

why only stick at left hand drive. I've often pondered building a bike with duplex drive, ie with a chain on both sides. A standard hub with two fixed sides ought to work, and then the load will only be half on each side.

Sounds good huh? Anyone willing/foolish enough to try it?

been done. same issue with pedals coming loose.

Now this is pointless. Have you ever had troubles with having an unequal load on your bike? You'd also get chainline issues x 2 especially since most bottom brackets are asymmetric.

To the original poster: as you've already said, your pedals will unscrew, and you may struggle to find a bottom bracket which fits.

If you had been at the last Rapha roller race in Waterloo Jos had one built up for display and rode it. He said it was weird.. just for fun clearly..

http://www.bikeforums.net/archive/in.../t-366418.html suggests many bottom brackets are symmetric....

I don't see it making much difference compared to running brakeless, in regards to the threads.. Lockring has almost as many threads as the cog anyway..

threads will run the other way though. helping it to unscrew rather than tighten under load

more load in skidding, than there is forward ;)
