hi, wanting to get a smaller inner (double) chainring for my wife's
bike than the 39t it came with. question is, how much lower teeth-wise
would i have to go for her to notice much at all when climbing?
already has a 12-27 cassette in the back.

likewise, anyone know where to get such a smaller one for a double?
seems like most retailers only have 39t.

thanks

39T is the smallest inner for most common double cranks. Get her a
so-called Compact 34-50 from anybody, and with that 27 in the back it will
climb walls.

On a standard crankset, the smallest chainring you can use is 39T.
To go smaller, you will need a new crankset (either compact bolt circle
or triple chainring).

If you have Shimano shifters, a cheaper solution may be to get a mountain
bike rear derailleur and cassette (up to 34T).

Just about. If it's a Shimano crank or other Japanese crank, a 38 can
sometimes be put on. But that's probably not enough to spend money
on.

buy a 34 rear cog, drill the cassette, take a lower out and out the 34
in
assemble it inside out
with 34 and buddy in the middle!

You might notice that the bolts that hold that chainring on are right next
to the teeth. Can't go any smaller. OK, you might find a 38 that will
fit, but it is not worth the expense.

You need to either go for a pie-plate cassette or a compact crankset,
which would let you get a 34-tooth inner ring. That would give a
significantly lower (13% lower than a 39) low gear.

You need to either go for a pie-plate cassette

You'll also need a long cage rear der and a longer chain.

Dear RB,

Er . . . maybe you're thinking of installing a larger rear cassette?
That might require a long cage rear derailleur and a longer chain.

But the original poster will be shortening his chain, not lengthening
it--he and David are talking about smaller front chain rings.

And changing to smaller front chain rings won't require a long cage
rear derailleur.

Cheers,

Er . . . yes, I am. That would be the "pie plate" cassette mentioned
above.

Perhaps I should have been more clear and written: "If you choose to
go with the larger cassette, you will need a... etc."

Dear RB,

Nah, you were clear enough.

I was the one who mis-read things, not you.

What could be more plainly a rear cassette than "pie-plate cassette"?

D'oh!

Sorry,

Well, I guess in the roadie 5-10% body fat world, a "pie plate
cassette" probably means a 12-27.

I think you'll find that, to Fabrizio, anything bigger than a /21/ in back
is a pie plate.
