Just bought an 04 Dahon Speed TR, have only put 29 miles on it in last three days and so far and very impressed.Will change the pedals for something not so slippery and looking for something other than the MicroAdjust stem. Tires, Marthaon Slicks seem fine. Also pleased with Thudbuster. I'm 67 years old and ride about 10 to 15 miles a day, hope to get back to the 25 miles per day I used to average about 10 years ago.
