both ends of the operation (cassette and chainset) and buy a new chain?

I'll respond until you get someone who knows what they're talking about.
You can *usually* install higher rated components with no problem. I
imagine the only real difference between the two CS is the smaller ring
on the Deore. The construction quality is probably very close.

Having said that, have you looked into just replacing the one chainring
instead of the entire crankset?

Contrary to your stated desire to have someone tell you the Deore 9 speed won't work on with your 8 speed, I regret to inform you the more expensive Deore 9 speed will work. Spacing between rings is a tad closer so there is a mild possibility you might need to adjust your fder cable to accomodate the minutely smaller tolerance your shifters would operate under with the closer rings.

BTW: Nashbar has lower prices on 26T Chainrings if you want to save some money:

You can use a nine speed chainset, 8 speed cassette with an 8 speed
chain. So, if you get the deore chainset, it'll be fine. However, why
don't you just get the chainwheel alone. If you can remove the 28
tooth chainwheel, replace it for a 26 and don't worry about the 8 or 9
speed denomination for the chainwheel. I am not sure of your chainset
model and it may be all welded together though.

If I remember correctly, the Nexave crankset does not have removable rings.

The 9 speed crank will work fine. Thats the way I went
till I got the rest of the parts, (9 speed chain,9 speed cassette,and 9
speed shifters) to finish up the upgrade to 9 speed. Also 9 speed
shifters work with 8 speed if you adjust the rear derailleur. And if
its a 8/9 speed rear derailleur.

Folks,

Many thanks to each for your kind help. Rhesus Monkey is correct in
suggesting that the Nexave crankset does not have removable rings, which is
why I unfortunately need to buy the complete unit . I hope the Deore comes
with removables, although I think this will be my final 'adjustment' (famous
last words I know!). But at least I have the solution so I'm happy.

Best regards to all,

Frank Tompson

Hi Frank,

I modified a Campag 32-42-52 set to 26-39-46 just by swapping the chainrings
(it was a road bike triple on a touring bike, and so too high-geared). You
have to be careful about the range - that is, the difference in tooth number
between the smallest and largest (in your case, currently 20). The front
mech won't tolerate your widening the range too much, although you can
nearly always use a wider range than the one specified (so I'm certain that
changing the 28T chainring for a 26T and thereby making the range 22 would
be perfectly ok).

With a drop as large as mine, from 39T to 26, I had problems with the chain
falling off when I shifted down to granny gears, but an Ngage Jumpstop put
and end to that.
