Ye Olde Favorite the Raleigh Twenty

Now that I have one I'm cosidering doing a little hopping up. Although I'd love to do something radical al' la Sheldon Brown. I'm thinking something along a "product improved" Raliegh Twenty and keep it a workhorse bike as the Raleigh engineers had intended her to be. Specifically I was thinking lighter rims, Shimano Nexus seven speed hub, and dispensing with the front Dynohub entirely. Wow, I never saw a Dynohub on a Twenty. As well as racks front and rear for hauling groceries or other cargo; however, after looking at some of the other Twenty's on E-bay and studing the racks available from the large mail order houses I'm wondering how would I go about putting racks on it. The racks I've seen attached to other twenties on E-bay look like they were specially designed for the twenty (and lets face it if they were it means they have been out of production at least 25 years.). Starting with the racks are there any suggestions as to where to find racks that would work? Anyone still making racks that would mount to the Raliegh 20 frame and front fork? Probably the best option is a seatpost mount rack. There are lots of those out there. See: http://harriscyclery.net/site/page.cfm?PageID=49&Category=86&Brands=All&type=T As for the later phases of the project the improvement of the powertrain who sells Nexus Hubs We do! http://harriscyclery.com/hubs-internal.html and how much would a package of the the Nexus hub, a fron't hub, a set of good alloy 20 X 1.75 rims be with enough spokes to build up the new wheels? See: http://harriscyclery.com/wheels A partial reason for swapping out the hubs is that the Sturmey Archer 3 speed hub has something wrong with one of it's speeds (doesn't engauge) If it's 2nd or 3rd gear, it's probably just a cable adjustment (or replacement-the original cables are very long and don't use modern lined housing) If it's 1st gear, there's a decent chance that oiling the hub will fix it. and although I'd love to get the dynohub working my twenty came without the front light and based on past discussions on here the dynohub light isn't much of a light to begin with so I rather save a pound or two and run a conventional front hub and do lights another way. Getting Dynohubs to work well with small wheels is just about impossible, nobody makes a suitable bulb for that application. I used to have a Moulton with a Dynohub, and every bulb I tried either gave a dim yellow glow, or burned out on the first downhill.
