Here is the link to the Mountaintamer Quad adaptor

They also make a triple adaptor. I used the triple with a 46,34,21 setup. The triple adaptor
replaces the inner ring and specers of my 5 bolt XTR crank. You can also use the triple to add a 4th
ring to a shimano road tripple. I am considering removing the outer ring on an Ultegra triple and
running a 42, 30, 18 tripple setup on my MTB.
I used to have an Avid, but sold it many years ago. It only went down to a 20t though. but, it
was lighter.

"Mountain Tamer" is mentioned. Avid is mentioned as "used to make one". I can find no links to
someone who sells them now..
The Mountain Tamer adapter would mount a Suntour freewheel cog on the 74mm bolt pattern.
Chainrings down to 18 (17?) teeth are possible. Want mine?
If you want to put a small chainring on a 130mm bolt pattern crank, Harris Cyclery sells TA
triplizer chainrings: sheldonbrown.comchainrings.htmlOpen ↗ . The smallest
chainring is 24 teeth, though.
