I noticed my Miyata 1000 is kind of harsh?? Maybe a combo of too much pressure on the Vittoria Randonneur tires and triple butted tubing, but I seem to feel every pebble on the road through
the rear tire. I think I will play with tire pressure and see if it improves.
For both speed and smoothness, it would have to go to my Treks.
First up, the 86 520!! OMG what a sweet bike. It has sealed bearing hubs on Matrix rims. Super
smooth, and will coast for a block or two if you let it. Great handling too, for a touring bike!! I find it to be too nice condition wise to ride it except when I know there's no chance of rain. Just an all around sweet bike
Second is a 79 510 made from Ishiwata 022, with NGS derailleurs and Superbe cranks. The ride is actually quite smooth. You can feel the big stuff, but road ripples and pavement gaps disappear. It also handles really nice, and seems to fly down the road with very little effort.
The 83 560. Another bike that seems to fly down the road and handles like it's on rails. It also
seems to have no twitch at all in the steering. It rides a little stiffer than the 510 ,but not a whole lot.
Probably the Reynolds 501 vs Ishiwata 022.
Next in line Is my 85 Club Fuji. Very responsive ride, but handles as well as the two lower Treks mentioned above. Something about the geometry of that bikes fits me perfectly. I have to lose the aero Dia Compe levers. The reach on them is just too far for comforts sake. I can reach them just fine, but my fingers don't find find the levers naturally. Too much thought required. Other than it's a top notch ride in my book. Rides smooth, yet is stiff out of the saddle. No BB sway like many bikes.,,,,BD
