Thanks all.
Another pointless question: some single speed trials bikes have a fixed cog on the back, and a LHD freewheel on the crank. What's the advantage to this, rather than just having them the other way around?
I had one on my trials bike back in the late 90's and I'm not sure what the benefit was. I just remember it eating my jeans a lot when I freewheeled it. I know it had a lot of points of engagement, but then regular trials hubs have that too.
Thanks all.
