Gear Ratios

Forgive the ignorance, but would a 14-28 result in a higher hear in the
smallest cog than a 14-24?

The smallest cog in both cases is 14, so the gear is the same in both cases.

No, they would be the same.

Ah, I'm evidently looking at it the wrong way around, the 14-28 then
would be lower in lowest than 14-24?

Yes. The difference (with a typical chainset, etc) is significant and worth
getting if you do/would find hill climbing a struggle with a 24.

Thanks, I believe my current one is a 24 and that's no problem.

I've often wondered what these MegaRange things were like to ride with
the 34 on the low gear. They seemed rather unnecessary for 6 speed
freewheels that they were/are on....!

I use mine all the time, with a 22 on the front. Very useful for towing
a trailer load of camping gear round the Lake District.

What puts me off with the Megarange specifically is not so much the 34T,
but the huge jump up to that gear. My MTB has a 32T biggest sprocket,
but it's a much smoother run up from the 11T smallest. This is coupled
with a 24/36 front, and is fine for winching myself up cliff-faces :-)

Depends where you are and how much gear you're carrying. Here we have a lot
of big hills but the gradients are on the whole not steep; I use a 53/39
double on the front and a 13/29 on the back, but my bikes are light and I
don't currently bring shopping home by bike. But in (e.g.) Devon, where
the gradients are steeper, I would really struggle. And if I were bringing
a week's shopping home on the bike, I'd probably change my route to the
longer-but-flatter one that I don't now normally use.

I agree with this concern. The 'bent has an 11-34 rear cassette with
fairly even jumps, and the 34 does get used and is appreciated, but I
had a MegaRange on a hire bike in Vancouver (which has some vintage
quality hills!) and I found it very annoying that 1st had been replaced
with a 0th, so changing down from 2nd led to a huge change which robbed
me of a lot of my momentum. I'd prefer a slight increase in all of the
jumps for a general purpose bike.

AOL. Although there is a big jump smack in the middle of the normal
cruising range on the 11-34s on both Speedmachine & Trice. I am stockpiling
parts for a rebuild of the latter's transmission, and one of the first bits
obtained is a SRAM 11-34 cassette, which seems to have slightly nicer
increments.

I used to think a "corn-cob plus underdrive" would be a Good Thing, until I
tried it...

Is it an Audi A4?

I'm currently thinking a corn cob (or at least more of a corn cob than
an 11-34) with no underdrive allied to an MTBish front triple might be
the thing to do when I've worn the current set out. It certainly won't
keep 52/42/30 on the front, which gives a barkingly silly high gear.

Or a Rohloff, if the boat comes in...
