11 speed gears

Has anyone ridden a bike with the Shimano 11 speed cassette and single
chain ring? I saw one at my local bike shop that had a 11 - 40 tooth
cassette and a single (looked like) 30 something tooth chain ring. It
looked like the difference in gear ratio between the gears would be
pretty big jumps.

Has anyone actually ridden one of these?

No, but I ride a Rohloff with 14 speeds (13.6% between gears) and I
would say that 14 is plenty for a rider like me (doesn't have to keep up
with a pack....).

Rohloff's total span is 526%.

Depending on the cogs put on the Shimano 11-speed, I could see it
working OK for certain riders - me included.

Yes.
The jumps are of course bigger than a 2x11 or a 3x11 but in
practice eleven is more than the 2x5 bicycles of my (very
high mileage) youth (8 useful) and wider gear range to boot.

8X2 is enough

can you say you understand know enjoy n appreciate more gears than 18 ?

Nope, I'm saying 1x11 is adequate, functional and popular.
There is no 'best'. Make your own choice. Me? Still on my
fixie this time of year.

Even when I was younger, it wasn't the number of gears, it was having a
high enough high and a low enough low.

In my area, if you want to do recreational riding that's any fun, you
have to head up out of the valley into the surrounding hills and
mountains, and for that you'll want a pretty low gear unless you're a
racer in extraordinary shape.

As long as you can get a range of around 22 to 110 gear inches, with
spacing that isn't more than 6 or 7 gear inches apart, I don't really
care what the mix is of front and rear chain rings and sprockets.

With 10-42 11 speed cassettes you can get the lowest and highest gears
you need with a front double at 52/36. Not sure if this is better than
going to a triple crank with say 54/36/28 and using a less extreme rear
cassette.

For me that still applies and now that I am older even more so. I do not
care at all about granularity. It could be way over 50% for all I care.
So I installed the steepest cassette I could fit on my old 1980's road
bike. To my surprise the old Shimano 600 rear derailleur took 32t.

Worse here. On road bikes we more or less roll down into the valley,
tool around down there, do some lengthy high speed stretches, run
errands or pick up a load and then have to slog it up the hills to get
home. 1200ft difference or so but with many ups and downs.

The last 6-7 miles are frustrating but I often sweeten that by carrying
home a growler. Where I can look forward to a nice evening with fresh
cold brewsky.

Triple plus a 32 or 36 cog on the cassette is IMHO the ultimate cat;s
meouw. Especially for that last steep hill after a zippy 45mi ride. Or
when taking a shortcut across rough turf.

thus sprake the LBS owner ....

kinda like Krygo's physics post.....in re how fast are you ?


when breaking on with 7 gears/friction shifters I would think....ahhhh thatsa nice gear.

3ith the 24 speed Redline cyclcrosser never happens only accidently. Now if I were faster, more practiced maybe I could thing ...ahhhhh 6/2 nice gear ahhhhh
yeah BS how do I know what gear ? I'm good to go if I know what CR we're in.

I understand the appeal of eliminating the third chain ring, or even the
second and third chain ring, but the cost of derailleurs that can handle
the 11-42 cassette, the cost of the cassettes, and the cost of the
chains, don't seem like a worthwhile trade-off to me. I've been using
triples for 35+ years without a problem. A 3 x 8 or 3 x 9 is fine with
me, I don't see the benefit of the 2 x 11.

Not worse there than the climbs around Steve -- at least not until you get up to Sierra passes or maybe down to that nasty climb on HWY 49 near Bagby. What you're describing is a rolling ascent. The SCV has stuff like this: https://s3.amazonaws.com/img.ultrasi...cc29262c5b.jpg One of my all-time favorite climbs except for the slippery crack seal **** they use in California. The Santa Cruz Mountain climbs are much steeper but shorter -- under ten miles.

Steve, however, does not have to contend with mountain lions -- just rich assholes in exotic cars trying to set speed records up Highway 9/Page Mill/Old LaHonda/Kings Mountain, etc., etc.
