Options For 23mm Adapters
 

As far as I have seen, there are 2 basic adapters for the 23mm Hex Rims.

one being for a savage, which doesn't increase width any, just converts to 23mm.

and the other being for 1/8 Buggies, which seems to slide over the 8mm stubaxle, with a pin n an oring. Now it seems to offset about 30mm to "bring the tire out to proper width"

I am lookin for an adapter like the buggy one (as I have the Savage 17mm conversion now, and could just change hexes) But I need an adapter that adds roughly 20mm of width (not zero like savage ones, and not 30mm like the buggy ones)

Does such a thing exist? I suppose I could go with the 30mm offset ones... but it might be too wide, and add extra stress on the knuckles that I don't need.

Thats just asking to wear out bearings. About the only other option I think you have other than wheel wideners is the FLM kit that increases the track width.

go with the 30 offset and settle with a non offset rimm.

or you could make your own!!
