The aesthetics of single speeds is pretty fun, but compared to my road bike is seriously lacking in utility.
So, one project that I have in mind would involve getting a Mercier TT single speed from Bikesdirect, and at some point in the future install an IGH on the rear wheel with a bar-end shifter. Apparently Sturmey Archer has some promising models for the 2009-2010 season.
Even better would be if I could just "drop in" the IGH without having to get new size spokes.
Anyone ever done it? thoughts?
Also, are there are any full-chain cases? Like, one that could cover both the top and bottom of the chain?
Lastly...lots of these bikes have a 48t front cog. For the rear, how big should it be? IGH's tend to have their 1:1 on the highest gear? so it would be like 48t-20t and then go down from there? If I went too high a ratio, like 48t-16t, would I run the risk of damaging the IGH?
