Changing Gears

[Christopher Mah]

I cycle in to work from Battersea to Holborn in London, and I notice that I seen to use my gears
rather differently to others. I change gears as if I were driving so that I start of middle of the
mid range, speed up a bit then go top range and up shift from there, then when traffic light
approach I shift back down to middle-middle again. In London this means a lot of gear changes! A lot
of other people on bikes though seen to stick to the high range or high gears all the time
(necessitating a somewhat slow initial acceleration). I am wondering, am I using my gears
incorrectly, I mean is it possible I might 'wear them out' before time by shifting so often?

Sorry if this sounds like a silly question, but I keep wondering about it!

What you have described there is the same way that I ride. Yes, you might wear things on the bike
out slightly faster, but by spinning away from lights in a fairly easy gear, you're not going to
wear your knees out.

Some are doing it deliberately because they don't mind starting in high gears*, but most people in
London simply don't know how to use their gears and hardly shift at all. So your technique is more
"correct" than theirs! Wear won't be much of an issue unless using crossed-over gears a lot (eg.
small chainring with smallest rear cogs).

My guess is that you've got a mountain bike or hybrid with a triple chainset with something like
22-32-42 chainrings - which are not very well suited to city cycling in my opinion. Changing the
middle ring for a larger size would mean you could use it for more of the time without having to
shift up to the big ring so often. But no point in changing anything if you're happy with what
you've got and it all works well.

* I'm one of those people when on my road bike (with a triple). I use the 39 tooth middle ring
mostly in London and can't be bothered to change down to a low gear for every stop, plus I find it
easy and fun to rapidly accelerate the (lightweight) bike from a high gear (compared to what you'd
probably use). I blast past all the mountain bikers with just a couple of pedals! It may look
like the roadies are struggling away in a big gear but it's quite easy really with the right
technique.

Aye. You can always buy new chainrings and cassettes from any LBS, and they aren't *that* expensive.

It is a far more difficult matter to procure a new set of *knees*, even if you are on BUPA

Gears are replaceable -- knees aren't. Your doing it about right.

unless its san fransisco or sheffield?

Although actually I was going to say I never use the little ring, but I do - on a spiral ramp of
the car park.

You do lots of cycling in multi-storey car parks do you?

I think you're doing it right. The idea, as already suggested, is that you should spin the pedals
quite fast rather than stomp them up and down, it's easier on zee knees. Gears are there to be used,
you could manage with only one but why? <waits for replies about lack of complexity, less to go
wrong etc.> ;-)

I have 22-32-42 + 9spd 11-28 and use the entire range in my 3 mile commute, both ways. The middle
ring is used whenever it doesn't look like a hill but actually it is. The lowest gets used several
times for some cycle lanes put up some very steep but short roads, plus Pitsmoor Road. I did once
get the "might as well get off and walk mate" line but I just thought "but I get to sit down and do
the same speed as you for less effort".

Hmmm, I'm not so sure - spinning legs around compared to walking. Getting off the bike and pushing
it used to be something I'd never do
- I've been defeated! But after having 20 miles 'normal' cycling left in me and losing it all on a
half mile hill I now get off and push. It may be the same effort - I don't know - but walking and
having a break from the saddle retains that 20 mile for me.

Regards,

Pete

Actually...

The car park at work is about 2-3 floors up, and comes at the end of 90mins of moderately
undulating road.

Going up is fun, but coming down in the wet can be interesting - esp as even knees and elbows don't
stop you immediately on such a thing.

1) I was really thinking of central London when I said "city cycling" (as the OP rides in London).
2) I know a big range can be useful but mountain bike triples aren't as conveniently arranged for
urban road riding as road triples (or doubles and singles). A larger middle ring provides
suitable gears for all the following: climbing gentle hills, cruising along on the flat and
going quite fast down moderate hills, with the other two rings saved purely for steep hills and
belting it. You have to use the big ring more with an MTB.
3) I've got nothing against granny gears and know that they are useful even within the London area:
eg. Hampstead.
4) ...er, I've forgotten what my fourth point was.

True. In reply to the OP I too used a lot of gears commuting in London, even though my route was
nominally flat. I don't think I used the lowest though.

But if you're changing gear all over the place anyway it's not much more effort.

It just so happens that there's a longish uphill stretch of my journey in which the steepest bit can
be done with middle chainring plus largest sprocket, so if I had a larger middle chainring I'd be
defeating the purpose you describe. Roll on variable ratio gearing systems. A cyclist friend of mine
is keen on that idea but I can't see how it could be done. Mind you he's also keen on VTOL
microlights as a mode of personal transport, and I've never been able to convince him that that idea
is unlikely to fly either...

Yep a hybrid here. It seems that the gearing is defintely higher on my hybrid compared to most of
the mountain bikes I see, which is nice. Thanks for all the comments (still reading) very
re-assuring

I remember seeing one on Tomorrow's World some years ago, with a chainwheel that automatically
expanded and contracted. Must have been belt drive, but I can't recall the details.

If is flat or flattish you don't need a lot of gear changes. I don't change gear often but remain on
the middle chainring (38T) with third smallest sprocket (17T) when starting and remain there until I
am either descending significantly (move to 15T or 13T or with good tail wind/burst of adrenaline
then hit the big chainring, 48T) or ascending significantly (where shift is needed to ease the work
on the knees).
