The rage seems to be 9, 10, 11 speed bikes. Most the true roadies I see look like they could devour a hill with a Fixie!
This is masterful marketing, is it not?
Getting next to impossible to get quality alloy 6&7 speed chainrings derailleurs etc. to keep my old faithful fleet in top condition.

Yeah, we had to ride our bikes in 3-foot snow to school with only a half a gear. .... Wait.... Hey, get off my lawn! .... OK I'm back.

Seems the low to top ratio spread is the most important thing, not the number of gears.

"9, 10, 11 speed......"???????

I could swear my Specialized has 21 speeds.

I think he means on the back cassette.

I suppose it is a personal question... what is the dynamic range for your level of fitness, power and use?

Its no different then engineering a drivetrain for a car or truck - what is the engine's power band, what is the application, what is the bias in terms of performance and economy.

Just like you can get a 3.23 or a 4.10 rear end on a truck, its kind of the same.

But I suspect that the real question is, what are the best highest and lowest ratios for the rear cassette for a bike to do _______?

I think that fewer intermediate gears are better, less need for close tolerances and less to go wrong. My shifters double shift if operated a certain way, and I most often use the double shift when I can to skip because otherwise there are too many cogs to go through that I dont need.

I think that if you are mountain biking, 21 speeds might be necessary.

When I was looking for my bike, I tried everything from 3-speed to 21 speed bikes.

Quote:

Which is the reason I settled on a 7-speed bike. My biking is rolling hills (about 30%) and flat terrain the other 70%.

Biking IMV is a great exercise if you can no longer run.

I thought 21 speeds have been around for a while. My hybrid bike is a 2006 model and has that many. There is a bit in the owner's manual that says 7th gear and 15th gear are not recommended because it's too much of a bend for the chain, so it's really more like 19 speeds.

I always thought 12 speeds were ideal on a road bike.

With the six cog stack on the wheel, the derailleur has an easier time indexing the desired gear.

If you're off road, it's a totally different situation.

Calculate the "gear inches." Most bikes have far fewer gear ratios than the number of speeds indicate. Eventually, you learn which "gears" work for you. Having more just means you have a better chance of finding the handful that work for you. When I was really into cycling I had a "12 speed" road bike (Miyata 310). I used about five of the combinations regularly. No matter how well adjusted the gears are the chain will rub in certain combinations. I never used those.

I think 7-9 speeds should be lots . I never could understand the need for 21 in fact I think there were some with more gears than that . Must be a thing to brag about ??

Less is better IMO .

I lived in Canmore Alberta for a few years many moons ago. I lived on 3 sisters mountain and used my bike to get around since finding parking is usually a nightmare.
I have a specialized rock hopper with a 9 speed rear,27 total gears and I basically rode everywhere on the small front sprocket unless I was climbing the hill home.
That many gears will have some overlap.

Again, number of chain ring and freewheel gear combinations is not the same thing as distinctly different gear ratios.

The trend was(is?) to move to 2 front rings and then more rear sprockets. As realistically, not many people would bother doing a bunch of front and rear gear changes, to go up the ratios in order.
I tend to ride that way too, on my mountain bikes, on a normal trail I just use the middle front ring until I need the lowest gears to climb a hill. Use the first 3-4 gears on the small front chain ring and then double shift up the middle chain ring while shifting down one on the rear.

Looks like a bunch of marketing to me. The 10-11 speed cassettes with very large 40+ tooth sprocket look good when paired with a single chainring. I'm itching to convert my 3x8 mountain bike to this configuration. Using an 11 speed with multiple chainrings looks a little redundant. Certainly is with 3 rings.

Same here.. the old 12 speed Huffy is a fine commuter. Thought about a small gear to go a bit faster not wise on my commute though!

Keep in mind that most of those "9-11 speed" bikes are actually 18, 22 or 27 speeds, depending on the number of spockets on the front. Keep in mind also that there's a lot of overlap among all of those gears.

What *does* matter is the high and low gearing. Low/easy gears are key if you live in hilly terrain, and previously really low gears were only available with lot o' gears.

That's completely changed. My new mountain bike has 11 speeds, total--but it has a wider gear range than my old "27 speed" from a few years ago. It's a total game changer, and one of the first unique products from the bike industry in quite a while. No front derailleur, no chain slap off-road, and a chain that will pretty much never come off. All with the simplicity of one shifter. Right now it's exorbitantly expensive, but the tech will trickle down. My guess: most recreational mountain and hybrid bikes--and even some road bikes--will be 11 speeds total in the next 3-5 years.

Eleven is kinda the magic number where you can have a big enough "big" gear, low enough "low" gear, and reasonable jumps between them-even in really hilly terrain.

As others have said, it's not the number of gears but the gear ratios. I was looking for one more gear this AM on my ride smile

But I held off my companions as we sprinted to the turn, so I guess I had enough gears.

3 speeds is all you need, for a city cruiser in relatively flat terrain. I have a Raleigh 3 spd from the 70s that is a great around town bike. Fenders and a chain guard so you can ride it in any weather without any special clothing. Its basically maintenance free, all you need to do is oil the internal gear hub a couple of times a year.

Gear it down so the 3rd gear is your cruising gear and the 1st two gears are for hills and for starting off from a dead stop.

That being said, I also have a road bike, 9spd Cannondale, that has the closest possible gearing since I ride in flat terrain. 53/39 chainrings and 13-19 + 21 cogset. Close gearing gives you by far the best efficiency and/or speed.

I tend to agree. A good three-speed is surprisingly sufficient.

In theory, a person operates best at a particular, fairly narrow rpm range, much like a diesel engine. This depends on fitness, the terrain, bike weight, etc. I can ride at between 1 and about 160 rpm, but have peak power output at about 105 rpm. My son is more efficient at about 95 rpm.

So while you can certainly do fine for certain things with even a single speed, the closer you can get to your own performance band, the better. Thus, more speeds, allowing for better selection for the variables involved. Not that I wouldn't say marketing is involved, but their is indeed science behind part of it.

As far as old chainrings and derailleurs for 6 and 7 speeds, chainrings won't matter up thru 9 speeds, and 10 will likely work fine. Old 8 speed Campy derailleurs use the same pull as 5-8 speed freewheels (not cassettes). Loose Screws used to be a great source for things like this, but they are out of business now. Harris Cyclery is another good source for info (and parts)

I've got an old Cannondale 6 speed that I keep an eye out for parts for this reason (aluminum 126mm spacing - not upgradeable) and snag parts when possible.

I ride flat FL roads. As such, I really only ride on a few cogs. Into the wind, zero wind and with the wind. It's possible that 3 carefully chosen speeds would work OK on most days.

However, there is always the day with the wicked headwind and a long way to go. On Christmas day, I had a 20MPH headwind, and a 27 mile ride home from work. That was a first gear day much of the time. However, when a truck passed, I could upshift for a bit and pick up speed.

I have 24 speeds on my mountain bike. Geared quite low - so I can ride it up any hill.

Now the problem is it's geared a bit too low for the paved trails I mainly ride now.

24 speed is real nice though. I think I only use 3 or 4 total.

Both my wife and I have 21 speeds, and we both use most of them at some point.

If we're leisurely riding the trail or riding with friends we use a completely different gear set than we do if we're pushing ourselves for exercise. If I'm riding alone I use a different set because I usually push myself much harder, especially when riding the entire 40 miles of trail. Without the additional gearing I doubt that I would be able to make the entire 40 mile trail in 1 hour, 45 minutes (average speed of about 22 MPH). When leisure riding we do the same 40 miles in 4 hours (plus lunch stops).

Given that the trail is fairly hilly, if I'm pushing myself hard I use a lot of different gears to keep my heart rate up and stay on pace.

If you have a 7 speed cassette whose smallest cog has 11 teeth and the largest cog has 32 teeth, and an 11 speed with that same range, the ONLY difference between the 7 and the 11 speed cassette is the ratio; more cogs allows a closer ratio shift. Unless you were a monster TdF cyclist or some ultra Type A competitor, 7 speeds is fine.

Holy cow, that's [censored] impressive. I haven't had a bike in a few years. I should pick one up soon, start riding again.

I just built a couple of mountain bikes with 29" wheels for friends.
One of them got an 11-36 ten speed cassette and a 30 tooth single ring up front. Only one ring, no front derailleur, no shifter, no cable.
Another one got the same cassette but insisted on a triple up front.
After riding both bikes, I think I'm going to do the single on my bike as well.

While an 11-36/30 tooth combo won't cut it for the terrain I'm riding, I think for most people in most locations that's an ideal spread. I'm using a 30T with a 10-42, and I can tell you use all of it (I spent about an hour continuous yesterday in a 30x42, and I was glad to have it!).

For me though the real advancement is with the "narrow-wide" chainrings. I thought it was just hype, but along with a clutch-type derailleur they really do work. I've ridden in some crazy terrain and I have yet to drop a chain. The simplicity of a single ring up front is hard to beat, particularly when the chain never falls off the front ring.
