An article on shift gears effectively was forwarded to us recently by an anonymous I Bike TOer. We agreed this might be useful for our readers (and if they still can't get the hang of it they can stick to single speed bikes).
The author is a bike mechanic that realized that an experienced cyclist was complaining to him about his gears but realized that they did not know how to properly shift their gears. So he rode around with him and came up with some tips:
Tip one: Pedal at a brisk pace. It’s better to pedal at a brisk pace using the easier to pedal gears than to muscle the harder gears more slowly. This technique will increase your stamina over a longer ride and will enable you to accelerate more quickly if you need to "jump". I promise you’ll still get a good leg workout. A brisk pace on the pedals also improves the shifting.
Tip two: And this is hugely important. Lighten the pressure on the pedals when you shift. Keep them turning, but don't be muscling down on them while you shift. Lightening the pressure on the pedals significantly smoothes the gear change, reduces those grinding noises when you shift, and lengthens the life of your drive train. You’ll have to anticipate your shifts a bit as you approach the hills, but it only takes a beat to change your gears on a hill once you get your timing down.
Tip three: Use your low numbered gears on the left with your low numbered gears on the right; and use your high numbered ones with the high ones. Thus, if you're in gear number one on the left, you should use it with gear numbers one through four on the right. Likewise, if you're in number three on the left, you should use it with gear numbers five and above on the right.
This tip has to do with chain line. Although no real damage is done using the wrong gears together, avoiding them prevents those rattles and rubs you sometimes hear. With the number of gears that come on today’s bikes, you can avoid "mixing your highs and your lows" and still find a comfortable gear in which to ride.
On road bikes, where you have to look down to see what sprockets the chain is on to determine what gear your in, avoid running the large sprockets on the front with the large ones in the back, and similarly, avoid using the small ones in the front with the small ones in the back. Another way to say the same thing is, when you’re chain is on the inboard ring on the front, it should be on the inboard cogs in the back. Similarly, when you’re chain is on the outboard ring on the front, it should be on the outboard cogs in the back.
Tip Four: Remember to shift back to a low gear before you stop so that you’ll be in an easy gear for starting out again.
When to change gears will be pretty obvious. You’ll want to shift to an easier pedaling gear (i.e. down shift to a lower number) when the bike gets hard to pedal up hills, and then shift to a higher gear (higher number) so your pedals can catch up when you go down one. Thus, we have come full circle on our gear shifting discussion. Gears make it easier to go up hills and let you pedal down them.
If this is all too complicated for you, just get a single geared bike! It builds muscle.

I *hate* biking in low gear
Fri, 07/24/2009 - 12:41Re: tip #1, that would drive me crazy. I hate the complete absence of resistance on a low gear. I bike in the same gear (3 and 5) at all times, including hills. The only time it's a bit of a problem is starting up but it only takes a few seconds to get up to speed so it's not worth the trouble of changing gears just for that. I think the last time I changed gears was a few months ago when I had the flu and even the flat stretches were feeling like hills.

AnnieD, I used to be like you
Fri, 07/24/2009 - 15:18AnnieD, I used to be like you for a while. And then I discovered how much faster and smoother I when I used the gears on my bike to their full potential. I never looked back!
No one is saying that you should have NO pedalling resistance. You definitely should have some, but it should be low enough to permit you to spin at about 80-90 rpm (as opposed to 50-60 where most "mashers" find themselves"). The higher cadence and lower resistance is better for your knees, better for your drivetrain, and makes you go faster (look at the rpms bike racers use... they're doing 120+!) And, yeah, wobbly starts are not just slow and bad for your drivetrain - they can be dangerous. You might get clipped by drivers starting from a stop... not to mention unsafely passed by impatient cyclists behind you, who might not necessarily be faster than you once they get going, but who are annoyed at your slow starts (not defending them; just saying that's likely to happen).
One reason I personally was averse to changing gears was because I rode a crappy bike on which the gears really did not shift properly. No wonder I was avoiding it. Shifting on a good bike is a pleasure, not a chore. You do it almost unconsciously, and the bike appears to miraculously stays in that perfect sweet spot, no matter what the riding conditions (uphill, downhill, wind etc.) are.

I'll give it a try
Fri, 07/24/2009 - 15:54but I must say, the high resistance does wonders for my stamina dancing soukous.

I just had my miele converted
Fri, 07/24/2009 - 22:01I just had my miele converted into a fixed gear, no more shifting gears for me EVER again.
(Fixed gear for those who don't know is a single gear bike that you can pedal forward or backward. )
I spent the money on the conversion because as much fun switching gears can be is when they break.... they break hard, not to mention I have insane amounts of stopping power now.
Reliability>Efficiency in the perspective of a bike courier.
(And toe-clips while not for everyone are freaking awesome.)

Internal hub gearing
Sat, 07/25/2009 - 01:42My Pashley has a five-speed internal hub gear. It is simple to use, and I don't have to be pedalling, so can shift when stopped. Internal hub also means low maintenance.
I like my bike.

Internal Hub
Sat, 07/25/2009 - 10:04Internal Hub Gear:
Advantages
* Because the mechanism is sealed within the hub and bathed in lubricant it is not exposed to dirt or weather. Consequently, hub gears need less maintenance than derailleur gears, and are more reliable, making them suitable for utility bicycles.
* Internal hub gears are not susceptible to impact damage in use or when the bicycle is being shipped.
* The gear can be shifted when the bike is stationary; derailleurs need the chain to be moving, which takes some trouble if the bike has stopped while in a high gear.
* Shifting is smoother than in external rear derailleurs.
* As the chain does not move sideways, it can be covered with a chain guard or even fully enclosed, protecting the rider's clothing from grease and damage, useful for utility cycling. A fully encased chain will maintain clean lubrication and last much longer than if exposed.
* The rear wheel spokes are symmetric on both sides of the bike. Symmetric spokes more evenly distribute load across the rear wheel and are an advantage where wheel loadings are high as in utility or touring bicycles.
* Hub gears have a single range of gears without overlap; for example a 14-speed hub gear has a high-to-low range of about 5 to 1, while a 24-speed derailleur system has 3 overlapping ranges with about the same total range but only some 16 to 19 distinct gears and a more complicated gear-shifting pattern.
Disadvantages
* Hub gears offering a wide range of ratios are very expensive, costing more than a frame and fork of reasonable quality.
* Some, especially those with a high number of speeds, are less efficient than derailleur systems, although derailleurs become less efficient when dirty and worn. A simple 3-speed hub when run-in and properly lubricated can match or exceed derailleur efficiency, benefiting from the lack of the derailleur's jockey wheels and perfect chainline.
* They are heavier than a derailleur system, also concentrating the weight towards the rear of the bicycle. The greater unsprung weight is also disadvantageous for a full suspension bicycle.
* They are considerably more difficult to repair than derailleur gears, where every component is accessible. Spares availability can, however, be very good as the difficulty of rebuilding the rear wheel, and the cost of a new hub, can make repair rather than replacement an attractive option.
* With 3 or 5-speed hubs there is usually quite a big jump from one gear to the next. Sturmey-Archer once made medium- and close-ratio 3 and 4 speed gears for racing, but these have been out of production since the 1960s.
Just thought i'd give a pro's and con's list as I didn't know much about internal hub gearing and I figured most other people didnt either.

internal hub ref?
Sat, 07/25/2009 - 17:26Do you have a source for this internal hub pro/cons?
A mechanic friend says he finds the 3-speed hubs still the best - reliable and sturdy. The newer 7speed and up hubs have axles that are too small. You can double check his claim - maybe you won't have any problems with them.

Internal Hubs are interesting....
Mon, 07/27/2009 - 22:32Particularly because I was looking at belt-drive systems. Such a system could either be single-speed or single speed with an IGH.
The only reason I'd switch from a dérailleur is for cycling in extreme conditions. I still have a mid-level dérailleur from 1994 which works flawlessly under most conditions - except slush.
I was looking at these new carbon-fiber belts and IGHs as a way to fight slush/chain rust(i swear you can see the rust forming some days) However, after looking around I think i would stay single-speed carbon-fiber belt if i was to try it, and here is why.
IGHs are expensive, heavy, offer no easy way to change a flat rear tire and... I know the manufacturers claim they're impenetrable but, lets be realistic, there are only levels of impenetrability when it comes to delicate things under such conditions. Then, after learning a simple repair can cost $200 easy because parts can not come separately, instead one must order a "complete "replacement kit, the final nail was put in that coffin. So they're fine way north or way south but here where we get a lot of freeze/thaw and salt/slush I'm staying away.
Has anybody tried those new Gates drive carbon-fiber belts?

gearing: use speedometer
Sat, 07/25/2009 - 23:52I did not believe that higher revs was more efficient until I started doing comparisions with my speedometer: it is! You will go 5% faster and expend less effort. If your legs are tired much, gear down.
Fixed which I too love... that is a different kettle.
Fastest way to accelerate or conquer a small rise is to stand up on your pedals, for either type.

Then again, I don't *want* to go fast
Sun, 07/26/2009 - 09:36Commuting, the only time I go all out is going up hills. Otherwise, I hold back to go slowly enough that I feel completely in control stopping for opening car doors or pedestrians popping out from between cars, or veering out of the way of potholes and suicidal squirrels (anyone else notice extra squirrels this year?). Greater speed is not going to win me over to the lower gears argument, in which case this might fall under the "fewer reps at a higher weight" argument versus "more reps at a lower weight". I considered getting a fixed gear bike but worried that the one gear would be too low, and the ones I've seen are more expensive than what I like to commute with - I like the fact that I can park my bike anywhere and (knock on wood) not have thieves look twice at it.

conversion project
Thu, 07/30/2009 - 10:45Hi Annie,
You could convert your current bike to a single speed bike, picking the gear you like to ride in best! A single speed is cheaper to convert to than a fixed gear, plus if you like to coast then definitely go for single speed over fixed.
AnnieD
I didn't know I could do that
Thu, 07/30/2009 - 11:00And true, I do like to coast - especially going down hills where I don't like to go too fast. But without the braking benefits of a fixed gear bike, which is a plus in winter, what are the advantages of single gear?
Tanya Q (not verified)
Coaster brake?
Fri, 07/31/2009 - 13:15For easier winter maintenance you could put a coaster brake onto the single speed. The single speed will be lighter, will have less chain wear with a straight chain line, and less parts to maintain with no cassette or derailleurs.
Svend
Nothing like coasting!
Fri, 07/31/2009 - 10:28I can't understand people who don't like to coast, fixies are a bizarre lot to me. I can see why simplicity, lightness and more control appeal to some, but give me my downhill reward! :-)

Shifter construction matters too
Mon, 07/27/2009 - 16:00The first time I ever rode a bike with rapid fire trigger shifters, it was a revelation. I grew up with those cheesy mountain bike shifters which were controlled by a lever; these eventually evolved into grip-shifters which are total shite IMO. Now it's 2009 and rapid-fire shifters are on the scene, and they are a pleasure - they're responsive, easy to use and very low maintenance.
The most useful tip in the whole list was the one which tells you to anticipate your shifting needs ahead of time. Downshifting when you're already on the steep uphill grade ain't gonna help ya - you need to have downshifted while still on level terrain.
Sounds like common sense but I hear gear-crunching coming from even the most seasoned cyclists.
