Finally got my Raleigh Twenty set-up with new wheels and it was a learning experience for me. Posted before about receiving Sun CR-18 451 rims instead of 406 from auction and went ahead and had a Sturmey 8 speed rear wheel built and a 90mm vintage hub installed in the front wheel. Primo Comet tires, tuffy tire liners, Koolstop pads and a new chain, 400mm seatpost and seat from my wife's 1980's Raleigh Marathon and I was ready. I had to remove the rear fender to install the 451 wheel. There is a spacer on the rear fender mount that prevented the wheel from going forward enough to get the axle in the dropouts. I love the gearing on the bike. I like to spin and don't find the gearing too low with the 46/25 as some have stated. I have experienced the 6th gear slippage that some have commented on even though everything seems to be properly adjusted. Even though I don't post a lot here I lurk and would like to tthank everyone for sharing their knowledge and experience on the Twenty. Pics attached. message.
