I've had my Tokyo for over a year and rode somewhere between 500-1000 miles in sunny weather only. Got a rear flat last week so I upgraded the tires yesterday to 100 psi (they are slightly skinnier than the stock 45 psi tires) and will ride on them today for the first time. 7-speed 11-28t freewheels are impossible to find. I'd sell an organ for one. I have an 11-28t cassette but have been thinking about selling it and sticking with the stock 14t freewheel or maybe upgrading to the 13t until I find one of the 11-28t unicorns on ebay.
