Retired and want to get back into cycling in my 60s.

Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Well they are really bike fit measurements rather than frame measurements as an isolated component. They just happen to reference points on the frame in situ relative to the ground. It would certainly be odd to use them for frame production, where individual tube lengths are more appropriate and donít depend on anything else.

I tried to explain the same to DaveSSS above, but despite his claim of understanding the trigonometry underlying our reasoning, he insists that seat tube angle is somehow a more useful number than effective top tube merely because he is used to the former.

I just turned 47 recently, this Sept. 12th. I also have a 30" inseam. I ride a 56cm frame on all my road bikes. I love rim brakes. Maybe when I get into my 60s, the disc brake technology would have drastically improved by then

Disc brake technology doesnít require drastic improvement. Itís already pretty well refined.

Not if the gripes and grumbles I hear from club members are a decent measure of "refined or not".

Sounds more like your selective hearing. I just rely on my personal experience, which has been positive. I've been using mtb disc brakes for over 20 years and road disc brakes since 2019. Over that time period I have experienced the odd contaminated pad issue (causing squealing) and one issue of resonant vibration under braking in a mtb rear triangle, which turned out to be worn suspension pivot bearings.

Oh.

Terry lives in a part of the world where it rains mostly from the end of November to maybe March. During the rest of the year, wheel rims are dry. In dry rather than wet or muddy conditions, the advantages of discs are lessened, and their disadvantages magnified.

What disadvantages are magnified in the dry? The only disadvantage Iíve ever experienced in 20 years is persistent squealing if the pads should get contaminated. Iíve had that happen a few times and it is annoying. But I wouldnít go back to rim brakes, especially not with carbon wheels.

I will also be surprised If disc brakes are going to get ďdrasticallyĒ better over the next decade. It is a pretty mature technology even if it is still relatively new on road bikes.

Price and weight.

Yes. Most of the time around here, rim brakes are more than adequate. But on a wet day with carbon rims, not so much. A rain bike with disc brakes would be a nice addition to the stable.

The grumbles and gripes I've heard from disc brakes owners were not about their stopping power.

I think the grumbles and gripes about disc brakes are mostly a measure of how much cyclists grumble and gripe about everything. The refinement of the object being griped and grumbled about is mostly irrelevant.
