am sure I would eventually drag something home. There seems to be a pattern .
I want to get ride of 3 step thru frames, the masi frame and the miyata frame. If you know a good home..... |
The Fuji is probably better. My miyata is an 81. It has short stays for a tourer. It is real comfy tho. It absorbs road shock real well.

Yeah it is. In fact I am thinking of downsizing to 1 bike. I like it better than anything else I have. If I sell the miyata and masi framesets I,can keep the wheels and change out wheelsets to get a new rig every other day.
I know 1 bike sounds crazy..... Actually doing it, is. . . . . . :ride: -Snuts- |

The advantage of 650b over 700c is mainly one of comfort. It doesn't really have anything to do with hills or gearing. You can now get much fatter 700c tires than previously, and bikes that fit them, so that does away with much of the advantage of 700c.
Yesterday I started commuting on a newly built up bike, which is a 45 year old Bottecchia frame now with 650b wheels. This is a good way to make an old racing bike much more comfortable. If one gets the same width 650b tire as a 700c tire, would the ride the same? What would be the differences? |

Riding with short cranks is a little odd at first, but I've done it, and I found I didn't notice the shorter crank after a few minutes; but when I went back to longer crank arms I noticed the unnecessary length for much longer, and strongly disliked it. I got over that; but the switch to short arms was much easier than the switch back. I still feel I am faster with shorter crank arms. Other than that, assuming the same rim and equivalent tires, the smaller wheel be lighter and will require less energy to get it spinning and less force to slow it down, so you 'should' get faster acceleration and faster braking; but the difference will be so marginal that I think you'll never notice it. Furthermore, most 650b road tires are pretty expensive, high quality tires. They will ride better than cheap 700c tires. But they will not necessarily ride better than 700c tires of the same quality. |
@rhm, I can't remember if I ever told you, but those 155mm cranks you convinced me to buy feel normal to me. I don't notice when I switch to them or back to 170mm cranks.

Okay, no, serioiusly, I'm glad to hear I didn't give you a bad tip. I have 160's on my daily commuter, and I don't notice the difference at all. I don't ride anything shorter than 160 at the moment, but I don't think I'd notice if I did. |

What I think it is, is that the longer the crank arm, the wider the range of motion in the knee. So even if none of my bikes had 170's, I'd maintain that range of motion by riding CitiBikes. But if I ride a bike with longer cranks, even just a little longer, I'm pushing my knees to the edge of unfamiliar territory. It's not painful, it doesn't do me any damage, and it doesn't seem to slow me down; but I definitely notice it.

Good theory, Rudi. I like it.
