I want a new chainset for my 'bent but need a triple that will take a 20
tooth small ring and have 165 or 170mm cranks. Any ideas what will do?

Deore?

My Deore chainset had a 22 tooth granny ring and 170mm cranks.

In current production, the Middleburn RS7 and RS8, and TA Vega and Carmina
spring to mind.

In general, you'll need a 56mm or the more common 58mm bcd 5-bolt fitting,
for which 20t was the smallest ring generally available.

If you're game to try eBay, many of the previous generation of mtb cranks
would fit the bill: Shimano XT M737, Ritchey Logic Compact, Sugino M900,
Suntour XC Pro Microdrive, RaceFace Turbine, and many others. Some were
available in both 110/74mm and 94/58mm (or 94/56mm) versions, so make sure
you know what you're bidding on if you choose that route.

There's also the TA Zephyr triple, later examples of which had a 110mm
primary bolt circle with drillings for both a 74mm and a 56mm granny ring.

They're all rarer in the lengths you're after than in 175mm.

For my money, the Ritcheys are the pick of the bunch, but they don't come
along all that often.
