Replacement chainrings

I have noticed that the chainrings on my touring bike have become very worn and would like to
replace them. They are marked Shimano SG, the sizes are D-48, D-38, D-28. Could anyone recommend
some suitable replacements?

Thanks

Chris

It'll probably be cheaper to just buy new cranks.

I've been looking to replace some chainrings too ... freaking expensive. The cheapest I've seen
consistently would be about $30 - $35 for the set (plus shipping). Occasionally there are sales ...
Nashbar recently had a sale on their chainrings at $3 a pop, however I called immediately and my
sizes were all sold out.

Is it winter where you are now (and are you riding)? If you're not going to be riding until spring,
I'd suggest waiting and look for sales, if any come up then snag them. If not, it may indeed be
cheaper to buy a whole new crank set.

C.Q.C.

If you need just one sprocket, there are lots of choices available, including genuine Shimano. If
you need all three, I think you'll discover that a mid-price crank set complete with chainrings will
be cheaper. The 48 tooth large sprocket is more typically found on a mountain bike than a tourer in
my experience, so you'll probably have better luck looking for a crank set in that market. Depending
on how they line up, you may or may not need to replace the bottom bracket in order to use the
replacement cranks. (Be aware that there are differences in the bottom bracket shaft on some bikes,
though; you most likely are looking at a crank that has a square-taper "shimano style" mount; ISIS
and Octalink cranks definitely won't work with your existing bottom bracket, and most Campagnolo square-
taper cranks will look like they'll work, but they'd be wrong. If you buy a bottom bracket to match
the cranks, then any type can be installed.)

Which cranksets come 48/38/28?

Seconded. Sell me the cranks if they're 165's.

You may want to look at Sugino chainsets because they do touring sets with bigger chainrings. All
Shimano stuff (except possibly the exorbitantly priced XTR) is compact drive these days.

Shimano TY-30 for $40

Sugino XD with a $10 upgrade

And he didn't say it couldn't be just similar, like a 26-36-48.
