Double Fixed Wheel.

[Boon 51]

Hi Guys.. I have just got myself a Specialized Langster and want to change the rear sprockets. Now I have seen a fixed/ freewheel wheel with the two sprockets on the same side. ( two one side and none the other) but can't find them anywhere so can anyone help in there location.

Cheers.

Mine's double fixed. The bike's from Condor in London so they would stock the hubs and build wheels if you wanted. Their wheels have been excellent

Same side, you wont find them. You ideally need a flip flop hub. Choices of fixed/fixed or fixed/freewheel. Sprocket each side.

Possibly was a bodge that you saw, but most importantly, the chain line will be poor and increases the chances of throwing the chain, which is something you don't want on a fixed.

OP says two sprockets on the same side.

They are located in Hades. One on each side is what you want, and will be able to find easily.

So he does. Didn't read it properly.
That said, why would it matter?

 

[Cycleops]

What would be the supposed advantage to having them both on the same side?

Yes you can get a double fixed sprocket with something like a 17/19 pair.

Will try and find a link.

These are the work of Satan

Given that the chain needs to be slackened to move it between sprockets, I don't see the point. You'd need to carry a 15mm spanner anyway, and I wouldn't want to risk the compromised chain line.
I've had a rear wheel lock up at 15 mph - 0/10 Would not repeat.

I had a set up once with a double 5242 on the front, with a flip flop rear with something like 14/17.

I Could train or ride out to an event using 42-17, flop the rear wheel and ride 52-14 for a time trial. May not have been those exact numbers, but the horizontal rear end coped with the required chain tension.

It only appears to make sense if you also have a 2 sprocket difference dual set up on the front to match it

How would you get the chain off without loosening the wheel?

no idea I've never used one. references to hades above suggests with difficulty.

potentially run your chain slack enough to accommodate changing set ups but tight enough so it doesn't unchain whilst riding - imagine that's a hard point to find and you're better of carrying a spanner with you, in which case you might as well flip flop.

probably why you don't see many around
