Chainring Sets - Recommendations???

You would need to consider the implications in having such a wide range
chainset, ie: extra long cage rear mech to take up the chain slack, as with
such a difference in the chainring sizes, this would result in a degree of
chain slack when on the small ring. I don't think such a device exists as an
extra long arm mech, so you would need to look for some other chain
tensioning device.

I'm looking for a chainring set for my Marin Muirwoods bike. It's the
standard MTB sizing with 26" wheels.

I need as full a range as possible i.e. 48T, 34T, and 22T or something
like that. This is so that on the flat, I can move quickly but when I do
mountains with a full pannier load, I am able to move into easier gears.

I've looked at chainreactioncycles.co.uk and wiggle.co.uk and neither
seem to have anything that would meet my needs.

Is there anybody else out there who might be able to provide me with
what I need?

Thanks, Danny.

Your local LBS, or plenty of other mailorder places.

Do you mean you need a new chainset (cranks and rings) or do you just
want some different size chainrings for the existing set?

You can probably get replacement rings for your existing chainset to
provide something like you want - what chainset do you have at the
moment, what size rings? Hoe old is the bike? newer bike are now 9 speed
(narrower chain), older bikes 7/8.

If you want a new chainset, then a quick peek would suggest something
like this:

Shimano Deore 44/34/22 for about GBP 50 - you could replace the 44 with
a 48 ring. Though changes might not be so clean up the big ring.

Or they have a cheaper Acera one.

Note the ring arrangement you suggest isn't a stock arrangement - so you
will need to change a ring or two anyway on a new one.

I don't think you're going to get that to work. That said, why the 48?

Most (if not all) MTB cassettes are 11-up and 48x11 is a very big gear.

22/32/44 is a standard and easy to get setup, and gives a reasonable top
gear. If you want something a bit bigger then you should be able to swap out
the 44 for a 46, but I'd expect the shifting to be very poor to un-unusable wiht
a 48.

The other alternative is to go with a non-compact MTB chainset 26/36/48, but you
lose the very low gears.

Two things about that chainset (I've just bought one, so I know): it's
impressively light; and it sits about 5mm further out on the bottom
bracket spindle than the Icon chainset it replaced. Fortunately it had
the same bolt pattern, so I swapped the rings onto the Icon and
everything fits.

However, this looks like the typical Shimano trick of being just a
little bit incompatible with the generics (Icon is Trek's in house
brand and so I would assume generic), so that to fit the new Deore
Hollowtech chainset you need to change your bottom bracket as well.

However, like I say, it's remarkably light.

That's nonsense. There are plenty of long arm rear mechs which are entirely
adequate for what the OP wants.
(A normal triple is 20 or 22t range, the OP wants a 26t range - that's
hardly a huge difference).

You may not have sufficient capacity to make small/small work, but you
wouldn't be using those gears anyway.

Our tandems have 50/38/24 rings on them, which is the same range as the OP
wanted, and they work fine.

cheers,
clive

William. My Trice runs 24-42-52. XT rear mech, Ultegra triple front. As
long as I don't do anything silly, like try to run on the 24 ring and the
smaller end of the cassette it's quite happy.
